- 00:00:00Astro 5 just dropped and while it's not
- 00:00:01the biggest update they've done it has
- 00:00:03some really awesome important New pieces
- 00:00:06and a few things that I don't think any
- 00:00:07Frameworks really done before obviously
- 00:00:10I'm the nextjs guy you probably know me
- 00:00:12for that but Astro is the only other
- 00:00:14framework I'm currently shipping in
- 00:00:15production I use it for things like my
- 00:00:17blog random docs we use it all over
- 00:00:19create T3 app that doesn't mean Astro is
- 00:00:21a solution that you should use instead
- 00:00:23of next for everything but these are
- 00:00:24both solutions to a lot of problems and
- 00:00:27they both learn from each other and the
- 00:00:28whole ecosystem gets to move forward so
- 00:00:30whether you're an astro Dev a next Dev a
- 00:00:32nu Dev a v Dev or you're still on cre
- 00:00:34react out for some reason there's a lot
- 00:00:36of good stuff to learn here so make sure
- 00:00:38you stick around but first quick
- 00:00:40commercial break today's sponsor is post
- 00:00:41hog and if your product has no users you
- 00:00:43can probably safely skip this section
- 00:00:45but for everyone else you really should
- 00:00:47consider post hog they might be paying
- 00:00:49me for this time but they're not paying
- 00:00:51me for my opinion and my opinion is
- 00:00:52almost everyone should be using post hog
- 00:00:55I've been using them for well over two
- 00:00:56years now way before I ever reached out
- 00:00:58to them to sponsor which by the way they
- 00:01:00didn't hit me up I'm the only person
- 00:01:02I've ever sponsored and they're doing it
- 00:01:03cuz I asked them to because I know you
- 00:01:06guys will like what they built they're
- 00:01:07an all-in-one Suite of product tools
- 00:01:09they have everything you need from
- 00:01:10feature Flags to analytics to session
- 00:01:12replays to surveys to so much more I
- 00:01:15have been surprised how many of these
- 00:01:17tools I've ended up using but if you're
- 00:01:18skeptical of throwing everything into
- 00:01:20one black box don't be it's not a black
- 00:01:22box whole thing's open source so you can
- 00:01:24do whatever you want to do if you want
- 00:01:26to host to yourself in the future you're
- 00:01:28not stuck on their platform but honestly
- 00:01:30ly The more I've learned about them The
- 00:01:31more I've seen their goofy wonderful
- 00:01:33brand and The more I've relied on them
- 00:01:35for my own products yes all of my
- 00:01:37products use poog the easier it is to
- 00:01:39recommend I think you'll be surprised
- 00:01:41and if you're curious yourself you
- 00:01:43should just go give the free tier a shot
- 00:01:44it's hilariously generous over 90% of
- 00:01:47companies don't end up needing to pay at
- 00:01:49all so yeah give them a shot thank you
- 00:01:52to post hog for sponsoring today's video
- 00:01:54check them out at soy. linkpos anyways
- 00:01:57Astro 5 is here and I am very very hyped
- 00:01:59for this release introducing Astro 5.0
- 00:02:02with the Astro content layer to load
- 00:02:04content from any source as well as
- 00:02:05server Islands to combine cached static
- 00:02:08content with Dynamic personalized
- 00:02:09content read on to learn more about
- 00:02:11these powerful new features and more by
- 00:02:13the way disclosure I have been so close
- 00:02:15with the Astro team for so long that I
- 00:02:17am officially an adviser which means I
- 00:02:19do have some Astro stock so there is
- 00:02:22bias here I think of it differently I
- 00:02:25think that I like Astro so much and they
- 00:02:27respect me so much that we have this
- 00:02:29relationship I get stock but obviously
- 00:02:32I'm going to be more biased towards the
- 00:02:34thing I have stock in than one I don't
- 00:02:35read my bias however you choose I like
- 00:02:37Astro enough to use my time to advise
- 00:02:39them anyways first and foremost what is
- 00:02:42Astro hopefully you know by now that
- 00:02:44Astro is the ultimate static framework
- 00:02:46that takes advantage of new tools the
- 00:02:48way I've personally thought of Astro is
- 00:02:50it brings the cool learnings and
- 00:02:52Powerful tools that we've gotten use to
- 00:02:54in like the react World over to the
- 00:02:56static generation of pages world I would
- 00:02:59get frustrated using something like
- 00:03:01react for a Blog but I would get more
- 00:03:03frustrated trying to do it the right way
- 00:03:04with static stuff Astro lets me generate
- 00:03:07HTML using whatever tools I'm used to
- 00:03:09using with a really good Dev experience
- 00:03:12and there's a reason it is quickly one
- 00:03:14in the blogging World a bunch of the
- 00:03:15e-commerce World in these more static
- 00:03:18focused experiences in their words Astro
- 00:03:20is the web framework for building
- 00:03:22content-driven websites including blogs
- 00:03:24marketing and e-commerce if you need a
- 00:03:25website that loads fast with great SEO
- 00:03:27Astro is probably the right choice for
- 00:03:29you this release has some really cool
- 00:03:30highlights including the content layer
- 00:03:32stuff the server Island stuff simplified
- 00:03:34pre-rendering types of environment
- 00:03:35variables v 6 and experimental features
- 00:03:37I am genuinely really excited for a lot
- 00:03:39of these server island is going to be
- 00:03:40the most mind-blowing so please make
- 00:03:42sure you stick around for that part but
- 00:03:44all of this is very exciting in the
- 00:03:45content layer part is something I've
- 00:03:47actually pushed a lot in my advisory
- 00:03:49with them because it's one of the
- 00:03:50coolest things we lost with Gatsby that
- 00:03:52is really important for these new
- 00:03:53Frameworks to be successful looks like
- 00:03:56they also have an upgrade command now
- 00:03:57which is cool I'm going to run this at
- 00:03:59the end of the video on my Astro site to
- 00:04:02see if it works or not so make sure you
- 00:04:05stick to the end for that first we need
- 00:04:07to look at the content layer stuff
- 00:04:09though Astro is the best framework for
- 00:04:10Content driven sites and with Astro 5
- 00:04:12we're making it even better the Astro
- 00:04:14content layer is a new flexible and
- 00:04:16pluggable way to manage content
- 00:04:17providing a unified types saave API to
- 00:04:19Define load and access your content in
- 00:04:21your Astro project no matter where it
- 00:04:23came from the use case for something
- 00:04:25like this is you have an old data source
- 00:04:27or a data source that isn't really built
- 00:04:29for typescript be it's something like an
- 00:04:32old WordPress blog a notion database
- 00:04:34some weird Google Sheets API and you
- 00:04:37want to get that into a new static site
- 00:04:39with better Dev tools Gatsby kind of
- 00:04:41went all in on this but they did it a
- 00:04:43very strange way they did it with
- 00:04:46graphql where you would have a
- 00:04:48typescript function that ran on your
- 00:04:50build or in servers that would fetch
- 00:04:52data from something like WordPress shape
- 00:04:55it as a graphql schema you would then on
- 00:04:58the client side hit hit that graphql
- 00:05:00schema to get the data you wanted
- 00:05:02dealing with all the nullability and
- 00:05:04that exists in graphql to get all
- 00:05:07that data into the react code to then
- 00:05:09generate a static site there were just
- 00:05:11so many back and forth and so many
- 00:05:13conversions from wordpress's API to
- 00:05:16typescript on the server to graphql back
- 00:05:19to typescript on the client but it's
- 00:05:21actually running on the build it's it
- 00:05:22was a mess but the idea of a unified
- 00:05:25layer that lets you access data in a
- 00:05:27typesafe way regardless of the source
- 00:05:29that idea is not kind of good it's
- 00:05:32really good and it's essential if we
- 00:05:33want to move these old WordPress sites
- 00:05:36into the modern era without losing all
- 00:05:38of our old content and now it is just
- 00:05:40part of Astro the content layer is huge
- 00:05:43and I'm really excited that it finally
- 00:05:45shipped Gatsby's already literally dead
- 00:05:47but this is this is the thing that
- 00:05:49brings the best parts of it and if you
- 00:05:51look at the code you'll hopefully
- 00:05:52understand why we have this package the
- 00:05:54notion astrol loader loader Globs with
- 00:05:58the pattern for all markdown files and
- 00:05:59it has this base Source data blog we
- 00:06:01also have the database which is a
- 00:06:03collection using the notion loader then
- 00:06:06we have countries which is another
- 00:06:07collection that is loaded through api.
- 00:06:10example.com countries and then we Jon it
- 00:06:13so now we have these three collections
- 00:06:14that exist within our asro app that we
- 00:06:16can access however we need to as we
- 00:06:19build our app huge so cool that if we
- 00:06:22like had our marketing site and we
- 00:06:24wanted to Port our old WordPress blog to
- 00:06:25it you just add the WordPress astrol
- 00:06:27loader add const Legacy blog equals to
- 00:06:30find collection and now you have access
- 00:06:31to that in your pages previously the way
- 00:06:34it worked was just dumping a bunch of
- 00:06:35stuff into markdown files in your repo
- 00:06:37so if you wanted a CMS to have some
- 00:06:39static sections of your site powered by
- 00:06:41a rest API or to have optimized images
- 00:06:44coming from an asset management system
- 00:06:45it would get messy quick and the loaders
- 00:06:48solves that problem you can use the
- 00:06:49built-in loaders to load content from
- 00:06:51anywhere on disk Define your own loaders
- 00:06:53that fetch content from any API in just
- 00:06:55a few lines of code and you can use any
- 00:06:56of the existing Community built loaders
- 00:06:59like store block Cloud ner High graph
- 00:07:02let's see if the important one is here
- 00:07:04tool for migrating WordPress to Astro
- 00:07:06look at that you got the pocket base
- 00:07:08loader sheet loader this is for Google
- 00:07:10Sheets good luck getting an API key from
- 00:07:13them but again this makes a ton of sense
- 00:07:16it's Pro I cannot imagine another tool
- 00:07:18where it would be easier to turn
- 00:07:20something like a Google sheet or an old
- 00:07:23WordPress site into a new static HTML
- 00:07:25experience without compromising on your
- 00:07:26Dev
- 00:07:28experience see so you see here we have
- 00:07:30the loaders for all our static stuff our
- 00:07:32markdown our Json whatever else CMS goes
- 00:07:34through a loader API goes through a
- 00:07:35loader you know have the one unified
- 00:07:37store you can access everything from
- 00:07:38this is huge they also made some huge
- 00:07:41performance improvements here the
- 00:07:42biggest argument against Astro in
- 00:07:44comparison to other static generation
- 00:07:46tools is that since it does everything
- 00:07:48in JS it's not as fast as some of those
- 00:07:50Alternatives but it's getting really
- 00:07:51fast now 5x faster builds for markdown
- 00:07:53pages on content heavy sites and up to
- 00:07:55two times faster for MDX nice not that
- 00:07:57the builds were slow but when you had a
- 00:07:59huge site they weren't as fast as I
- 00:08:01would have liked it's
- 00:08:03fixed but here is the biggest part I've
- 00:08:06talked about it a bit before but I'm not
- 00:08:08going to miss the opportunity to go in
- 00:08:10depth because server islands is so cool
- 00:08:13server islands are an evolution of the
- 00:08:14islands architecture concept that Astro
- 00:08:16helped bring to the mainstream I'll do a
- 00:08:19real quick overview of islands if you
- 00:08:21have a website with like a header and an
- 00:08:24image Carousel which are both
- 00:08:25interactive but everything else is
- 00:08:27static and you're using react your react
- 00:08:30bundle now has to come in and load all
- 00:08:33of these pieces in JavaScript in order
- 00:08:35for this to work islands are the idea
- 00:08:37that everything is static and doesn't
- 00:08:39require JavaScript unless it's an
- 00:08:40interactive piece and then each of those
- 00:08:42interactive pieces live on their own
- 00:08:44Island where they don't directly
- 00:08:46interface with other things maybe
- 00:08:47there's a greater store that they're all
- 00:08:48hitting in like Global or whatever but
- 00:08:50the idea is that these pieces can be
- 00:08:53isolated islands that don't need the
- 00:08:56whole site to be one JavaScript
- 00:08:58framework to work and these islands
- 00:09:00don't have to be in Astro in fact they
- 00:09:02can't be because Astro doesn't do client
- 00:09:04anything you bring in the JS framework
- 00:09:06of your choice and they support pretty
- 00:09:09much all of them it supports everything
- 00:09:11from react to view to spelt to even
- 00:09:14angular last I saw I know solid works
- 00:09:16really well in fact solid start used to
- 00:09:17be based on Astro it's really powerful
- 00:09:21for a thing that's mostly static with a
- 00:09:23few Dynamic Parts you know like a blog
- 00:09:26or an e-commerce site the new nextjs
- 00:09:28patterns in a a lot of the winds that
- 00:09:31exist here but nowhere near the same
- 00:09:33power of the the mindset and it also is
- 00:09:37a bit more complex because of the way
- 00:09:38everything interweaves in server
- 00:09:39components where here it's very almost
- 00:09:42like boringly linear top to bottom where
- 00:09:45from this element down it is now a
- 00:09:46dynamic component everything above it is
- 00:09:48just part of the Astro world but what's
- 00:09:50cool is when you mount a react component
- 00:09:52for your header or for your image
- 00:09:53Carousel you can tell Astro run this on
- 00:09:56the server and just put it in a static
- 00:09:58HTML or run it the server but also send
- 00:10:00the JS to the client or don't run it on
- 00:10:02the server only run it on the client you
- 00:10:04get a lot of flexibility in how Astro
- 00:10:07treats the island but you do have to
- 00:10:10architect with these islands which
- 00:10:11prevents things like multiple components
- 00:10:13in the same tree that are being shared
- 00:10:16between things you just have to do that
- 00:10:17all in the react or other framework
- 00:10:19layer yourself Astro doesn't give you
- 00:10:20that composability it lets you do it
- 00:10:22yourself however you want benefits and
- 00:10:24negatives soone in chat just asked could
- 00:10:27you use Astro to make a site that uses
- 00:10:28every major your framework you could
- 00:10:30good luck and also as I was saying like
- 00:10:33if you want to compose these you can't
- 00:10:36like put an angular component inside of
- 00:10:38a react component using Astro once you
- 00:10:40mount the react component from there
- 00:10:42down it's all just react so you have to
- 00:10:44be considerate of that when you do it
- 00:10:45but you can pass it props from Astro to
- 00:10:47react so balances benefits negatives
- 00:10:51it's a cool thing when you need it but
- 00:10:53it also lets you rethink things that are
- 00:10:55mostly static a harsh reality was that a
- 00:10:57lot of people were using react because
- 00:10:59they this image Carousel even though the
- 00:11:00rest of the site didn't need it they
- 00:11:02would have the whole thing in react now
- 00:11:04Island helps prevent those things if a
- 00:11:06site should be static but one part
- 00:11:08shouldn't be this is the best
- 00:11:09architecture to solve that problem but
- 00:11:11we're not here to talk about islands in
- 00:11:13the traditional client side sense that
- 00:11:15we just went through that was almost
- 00:11:17almost misleading to be so focused on
- 00:11:19that because what we're here to talk
- 00:11:20about today is server Islands which is a
- 00:11:23very different way of thinking about
- 00:11:25stuff I'm going to start this section by
- 00:11:28talking about next because nextjs
- 00:11:30introduced a feature called partial
- 00:11:31pre-rendering that is very similar in
- 00:11:34its goals if I have a website that is
- 00:11:36mostly static let's say it's a
- 00:11:39e-commerce site most of the things on
- 00:11:41that page are going to be the same for
- 00:11:42everyone but some will be different the
- 00:11:44carts going to be different the
- 00:11:47recommendations are going to be
- 00:11:48different the shipping information is
- 00:11:50going to be different so why do I have
- 00:11:52to wait for the server to generate the
- 00:11:54whole page if a lot of the page is
- 00:11:56static partial pre-rendering is a
- 00:11:59feature feature in next where you can
- 00:12:00generate and cache the part that's the
- 00:12:02same for everyone and then stream that
- 00:12:05down immediately when the user goes to
- 00:12:06the page and then have the rest fast
- 00:12:08follow up after when it's ready so it's
- 00:12:11all part of one stream one request the
- 00:12:13user makes the static part comes through
- 00:12:15really fast and the rest gets streamed
- 00:12:17in when it's ready the benefit here is
- 00:12:19that it's all one request and you don't
- 00:12:21have to worry about the static Parts
- 00:12:24being blocked by the dynamic parts and
- 00:12:25that's the goal here to not block the
- 00:12:28static part on the part that is unique
- 00:12:30to a given user so this is cool but it
- 00:12:33requires some crazy in for hacks because
- 00:12:35you need to set your server up so that
- 00:12:38it can intercept the request send down
- 00:12:40the static part and while holding that
- 00:12:42same connection slowly stream in the
- 00:12:45rest of the stuff when it's ready that
- 00:12:46is an infer feature as much as it is a
- 00:12:48framework feature and getting PPR
- 00:12:50working on things that aren't versell or
- 00:12:52netlify is not a fun experience Astro
- 00:12:55saw the benefits of PPR but they didn't
- 00:12:57want to force you to have this complex
- 00:13:00architecture where the server responds
- 00:13:02with two different sources one is the
- 00:13:04static part and one's the dynamic part
- 00:13:06all as part of one complex streamed
- 00:13:08request server islands are almost an
- 00:13:11inversion of this way of solving the
- 00:13:13problem with the goal of solving the
- 00:13:14same problem instead of having a server
- 00:13:17that sends down the CDN part and then
- 00:13:19follows up with the stream part now the
- 00:13:22CDN gives you the static part completes
- 00:13:25the request it loads a little bit of JS
- 00:13:27that little bit of JS re requests to
- 00:13:29your Astro server hey I need a little
- 00:13:31bit more information can I have it
- 00:13:33please and then it sends the rest down
- 00:13:34to get swapped into those individual
- 00:13:37Parts the benefit here is you can deploy
- 00:13:39this the way that we've always deployed
- 00:13:41static stuff by throwing it on S3 and
- 00:13:43maybe giving it a CDN with cloudfront or
- 00:13:45cloudflare without having to do the
- 00:13:47complexity of the request mangling and
- 00:13:50we still get pretty close to the same
- 00:13:52performance we saw with next partial PR
- 00:13:53rendering if not better in many cases
- 00:13:55it's a really cool solution that allows
- 00:13:57you to get that benefit without going
- 00:13:59all in on very tailor made specific
- 00:14:02infrastructure now you can throw the
- 00:14:04Astro part on any node server in the
- 00:14:07static Parts on any CDN and it just
- 00:14:10works that's awesome having a framework
- 00:14:13primitive that lets you say okay
- 00:14:15everything above here is a static site
- 00:14:17that goes into CDN and when you want to
- 00:14:19load these parts these have to come from
- 00:14:21a server I like their framing here for
- 00:14:22Server Islands on any given page you
- 00:14:24might have content that is completely
- 00:14:26static and never changes some content
- 00:14:28that's dynamic backed by a database that
- 00:14:30changes infrequently but more often than
- 00:14:32you do deployments as well as some
- 00:14:33personalized content which is tailored
- 00:14:35to individual users all three of these
- 00:14:37have entirely different Optimal
- 00:14:39Solutions the static Parts should be on
- 00:14:41a CDN the dynamic Parts should be on a
- 00:14:43CDN with an invalidation or a static
- 00:14:46revalidation pattern and the
- 00:14:48personalized content should be fully
- 00:14:49Dynamic on request the issue before is
- 00:14:52that as you went down this chain you
- 00:14:55would usually give up the benefits of
- 00:14:56being higher up the reality it is we
- 00:15:00want our things to be as close to the
- 00:15:01top as possible we want our stuff to be
- 00:15:03static because the higher up here you
- 00:15:05are the faster things are if you're
- 00:15:06completely static it's super fast if
- 00:15:08you're mostly static but revalidate it's
- 00:15:11pretty fast but has more compute and
- 00:15:13sometimes things are stale and if it's
- 00:15:15fully Dynamic you have to wait for the
- 00:15:16server to generate on every single
- 00:15:18request sadly if you have just one
- 00:15:21personalized part like the cart in your
- 00:15:24e-commerce site with pretty much every
- 00:15:26architecture that's existed in the
- 00:15:27history of the web you have now forced
- 00:15:29your entire site to be dynamic so even
- 00:15:32if the rest of the content is static
- 00:15:35just one Dynamic piece means the whole
- 00:15:37page now has to be loaded in a dynamic
- 00:15:39way which means every request the user
- 00:15:41makes going forward is now significantly
- 00:15:43slower but what if the static Parts
- 00:15:45could stay static and we bring in these
- 00:15:47different Dynamic patterns for the
- 00:15:48elements it make sense for not the
- 00:15:50routes or the pages it make sense for
- 00:15:53dynamic shouldn't be a route level
- 00:15:54concern it should be a component level
- 00:15:56concern and that's what's really cool
- 00:15:58here
- 00:15:59as they say previously you had to choose
- 00:16:01one caching strategy for all of your
- 00:16:03content types and if the page is a
- 00:16:05logged in experience that usually would
- 00:16:07mean no caching at all now with server
- 00:16:09Islands you get the best of both worlds
- 00:16:11the things that are the same for
- 00:16:12everyone can be fully static the things
- 00:16:14that are unique for everyone can be
- 00:16:16fully unique and dynamic the goal here
- 00:16:18and you're going to see this pattern
- 00:16:19more and more as new Frameworks are
- 00:16:22adjusting to these patterns and the cool
- 00:16:23stuff that's going on in the react next
- 00:16:25World our goal is to make as much of our
- 00:16:28site as static as possible because CDN
- 00:16:31will always be faster than running a
- 00:16:33server and it's really cool to see
- 00:16:34Frameworks like Astro acknowledging that
- 00:16:37there are things that have to be dynamic
- 00:16:38and instead of pretending it's not a
- 00:16:40problem or forcing you to do it on the
- 00:16:42client side we can just load those parts
- 00:16:44in when they're ready server islands are
- 00:16:46used for your most dynamic content
- 00:16:47personalized content like a user Avatar
- 00:16:49their shopping cart and product reviews
- 00:16:52while these components are deferred
- 00:16:53you're free to more aggressively cach
- 00:16:55the page itself that means that if a
- 00:16:56user's logged in or not they will still
- 00:16:58see most of the critical parts of the
- 00:17:00page instantly as they are cached on
- 00:17:02edge cdns you can also set custom
- 00:17:03fallback content to show briefly before
- 00:17:05the dynamic islands are loaded think of
- 00:17:07this like the fall back with a suspense
- 00:17:08and react each island is loaded
- 00:17:11independently to optimize the visitor
- 00:17:12experience this means a slower Island
- 00:17:15like one connected to a legacy backend
- 00:17:16won't delay the rest of the personalized
- 00:17:18content from being seen and interacted
- 00:17:20with also a big thing the biggest
- 00:17:22problem with the all Dynamic thing is if
- 00:17:24you have one element that takes half a
- 00:17:27second one that takes a third of a
- 00:17:28second but one that takes 3 seconds the
- 00:17:30whole page takes those 3 seconds if you
- 00:17:33use any sites that are really slow like
- 00:17:35uh angelist it's one I use a lot that's
- 00:17:38disgustingly slow the reason is it's
- 00:17:40generating all of the things it has to
- 00:17:43for the page it doesn't show you
- 00:17:44something when the fast parts are done
- 00:17:46it shows you nothing until all of them
- 00:17:47are done it's kind of like the chain is
- 00:17:49or a chain is as strong as it weakest
- 00:17:51link a page is as slow as it slowest
- 00:17:53element now things come in when they're
- 00:17:55ready instead of when everything else is
- 00:17:57done but that also means you have to be
- 00:17:59careful because you might end up in
- 00:18:00loading spinner hell if you don't plan
- 00:18:01accordingly around this they've been
- 00:18:03shipping server islands for a bit and
- 00:18:04they got really useful feedback that
- 00:18:06they've applied such as the ability to
- 00:18:07set headers inside of an island which
- 00:18:09allows you to customize the cash
- 00:18:10lifetime of an individual Island that's
- 00:18:13actually really cool to say like the
- 00:18:15reviews on an e-commerce site that only
- 00:18:18needs to be revalidated every day but
- 00:18:20maybe you want the cart to be never
- 00:18:22cashed ever you want that to be like
- 00:18:24invalidated whenever you request it
- 00:18:26being able to do that on an individual
- 00:18:28Island level is really really powerful
- 00:18:30I've seen a little bit of this through
- 00:18:32believe it or not netlify they have a
- 00:18:34cool header called netlify VAR that lets
- 00:18:37you split the places that you're getting
- 00:18:39cash data from based on conditions in
- 00:18:42things like your cookies the request the
- 00:18:44time of day those types of things where
- 00:18:46you're basically telling the page which
- 00:18:50CDN to get stuff from and which static
- 00:18:53asset to pull based on something more
- 00:18:55Dynamic and what Aster's enabled here
- 00:18:58with is level headers is a more granular
- 00:19:01version of that and I'd be surprised if
- 00:19:03like on netlify they weren't using a lot
- 00:19:04of those custom netlify headers to make
- 00:19:06this possible in fact I would bet that a
- 00:19:08combination of things like the net very
- 00:19:10headers and Astro could make something
- 00:19:12like stupid
- 00:19:14performant oh you can also use server
- 00:19:16Islands on platforms that do automatic
- 00:19:17page compression that's cool I'm not
- 00:19:19surprised this broke things in the past
- 00:19:20but I'm hyped that they found a fix for
- 00:19:22it because that is the thought of your
- 00:19:24CDN or your web host doing gzip and
- 00:19:27broley stuff for you automatically
- 00:19:29causing this the diffs to not fit right
- 00:19:31that doesn't surprise me but I'm happy
- 00:19:33they found a solution to it they also
- 00:19:34automatically encrypt server Island
- 00:19:36props using a key generated by the
- 00:19:37server oh that's good next had this
- 00:19:39problem with server actions I'm happy
- 00:19:41they found a solution to Astro as well
- 00:19:42but again it's like they're taking and
- 00:19:44this is what I like about tools like
- 00:19:46Astro there's a lot of tools that exist
- 00:19:48in spite of the existing Alternatives
- 00:19:51like I'm going to get in trouble for
- 00:19:53talking about it but ladybird doesn't
- 00:19:54exist because they see things that are
- 00:19:56cool in the existing browsers and they
- 00:19:57want to do cool stuff on top or they
- 00:20:00have a specific thing they want to fix
- 00:20:02it exists because they don't like the
- 00:20:04companies making the other browsers and
- 00:20:06they just want to do it from scratch
- 00:20:07Astro wants to make the web better and
- 00:20:09make building for the web better so when
- 00:20:11other tools come from other companies
- 00:20:14like nextjs they don't look at it and
- 00:20:17say well no one ever will want that
- 00:20:19we're going to keep doing our thing they
- 00:20:21look and say oh there are really useful
- 00:20:23parts and within those parts there are
- 00:20:26really useful solutions to problems they
- 00:20:28encounter and they're taking those
- 00:20:30lessons and those learnings and those
- 00:20:32value ads and bringing them to devs that
- 00:20:34aren't using next for any of many
- 00:20:36totally valid reasons it's awesome to
- 00:20:38see tools that aren't the most popular
- 00:20:41tool not pretend that the popular tool
- 00:20:43is always bad but actually learn the
- 00:20:45lessons that they're learning and
- 00:20:47applying them to their own context it's
- 00:20:48really cool to see it's one of my
- 00:20:49favorite things about Astro and the
- 00:20:51Astro team one of my good friends on the
- 00:20:53Astro team Maple who's hanging out in
- 00:20:54chat right now was a remix guy like
- 00:20:56they're real deep in the remix community
- 00:20:59so they brought a lot of those lessons
- 00:21:00to Astro as many of the others on the
- 00:21:02team have with Astro 5 we are rethinking
- 00:21:04what it means for a site to be static
- 00:21:06server Islands provide a foundational
- 00:21:08primitive for how you build static
- 00:21:10projects in Astro in the future with
- 00:21:12Dynamic bits only when you need them to
- 00:21:14learn more about server Islands you can
- 00:21:15check out the server Island guide I also
- 00:21:17did a more in-depth video on them
- 00:21:18hopefully you've gotten what you need to
- 00:21:19here links in the description if you
- 00:21:21want to check out this guide though
- 00:21:22really cool stuff and remember we're
- 00:21:25going to update my site to Astro 5 at
- 00:21:26the end so stick to then if you want to
- 00:21:28see how hardest upgrade they also
- 00:21:30simplified pre-rendering since Astro's
- 00:21:321.0 release Astro supported multiple
- 00:21:34output modes for websites static when
- 00:21:36you want to just generate HTML files as
- 00:21:38well as server when you want the pages
- 00:21:39to be dynamic and run at runtime instead
- 00:21:42funny enough previously you had to opt
- 00:21:45your whole app into static where it
- 00:21:47would generate HTML or dynamic but I
- 00:21:49would often have routes I wanted to be
- 00:21:50static and routes I wanted to be dynamic
- 00:21:52so I I complained a lot and they fixed
- 00:21:54it really fast but like yeah fun weird
- 00:21:57chaotic time I was real frustrated and
- 00:21:59this happens a lot where there are two
- 00:22:01cool things a tool does and I can't do
- 00:22:03both at the same time it annoys me to no
- 00:22:05end and they took that problem seriously
- 00:22:07and they've went out of their way to
- 00:22:08address it since after many requests in
- 00:22:10Aster 2 they made it more granular by
- 00:22:12creating a third output mode hybrid
- 00:22:14which lets you have some things be
- 00:22:15static and dynamic which is again from
- 00:22:17me complaining so much and I'm sure
- 00:22:19others too it was the obvious thing they
- 00:22:21need to do but I was I was loud about
- 00:22:22that I even had an interview with Fred
- 00:22:24from Astro where I just roasted him for
- 00:22:26this and he realized oh yeah you're
- 00:22:27right we should fix that as Astro grew
- 00:22:29and gained more powerful features like
- 00:22:30actions on server Islands which cannot
- 00:22:32be used in a purely static output mode
- 00:22:34we realized that the Matrix of what
- 00:22:36settings do I need to use this feature
- 00:22:38became large and tiresome to explain and
- 00:22:40document we also found that people ended
- 00:22:42up server rendering more than they
- 00:22:43needed to because it was easier than to
- 00:22:45use the fine grain controls which
- 00:22:46resulted in their sites being slower
- 00:22:48than they had to be with Astra 5 we're
- 00:22:50happy to say we've simplified all of
- 00:22:51this the hybrid and static options have
- 00:22:52been merged into the default static
- 00:22:54option
- 00:22:56yes yes this is always what I wanted
- 00:22:59thank you it's funny I would argue this
- 00:23:01is them beating nextjs to the punch with
- 00:23:04Dynamic IO where the the goal is to have
- 00:23:07the static Parts always be static and
- 00:23:09things you do in your code tell the
- 00:23:12framework when to start being Dynamic so
- 00:23:15assume static until you hit some
- 00:23:17boundary that says hey this part is
- 00:23:18dynamic then do that Dynamic leave
- 00:23:20everything else a static we are there
- 00:23:22and Astra now huge this allows you to
- 00:23:24render individual routes at runtime on
- 00:23:26the server just by adding an adapter no
- 00:23:28more configuration is needed fear not if
- 00:23:31you still want good old statically
- 00:23:32generated HTML you still get them Astro
- 00:23:34is still static by default but if you
- 00:23:36set pre-render false on a given page AST
- 00:23:38now dynamically switches its output mode
- 00:23:40which allows you to use features that
- 00:23:42require SSR without figuring out which
- 00:23:44config mode that you need awesome and if
- 00:23:47you combine that with server Islands you
- 00:23:48can just make everything static and have
- 00:23:51certain parts that are treated Dynamic
- 00:23:53huge awesome A++ interesting Astro and V
- 00:23:57more T3 inspired stuff if you're not
- 00:23:59familiar there's a package that Julius
- 00:24:02made for T3 in create T3 app that's now
- 00:24:05gone way further T3 environment which
- 00:24:08lets you use Zod to validate your
- 00:24:10environment variables so you can access
- 00:24:12them in a typ safe and runtime safe way
- 00:24:15and it gives you errors during build if
- 00:24:17you're missing environment variables
- 00:24:18which makes setting things up and
- 00:24:19accessing them from different code bases
- 00:24:21in different developers way easier it
- 00:24:24seems like they've built this into Astro
- 00:24:26which is awesome I don't think T3 andv
- 00:24:29should have to exist but no Frameworks
- 00:24:31take these problems seriously so it does
- 00:24:34and I've seen this package used way
- 00:24:36outside of the react next ecosystem I've
- 00:24:38seen it in a bunch of solid code bases
- 00:24:40so it's cool to see Astro taking this
- 00:24:42opportunity to make Astro better in a
- 00:24:45lot of ways you could say Astro is
- 00:24:47copying stuff we did in T3 like from the
- 00:24:49CLI to the plug-in architecture to the
- 00:24:52environment stuff I love that I
- 00:24:55genuinely really really like that they
- 00:24:57see the DX winds that Exist Elsewhere
- 00:25:00and they bring them into the framework
- 00:25:01itself so you don't have to know about
- 00:25:03all these things to have a good
- 00:25:04experience I love this I would never
- 00:25:07accuse them of copying or stealing I see
- 00:25:10this as good ideas being proliferated oh
- 00:25:13that's actually really nice you can
- 00:25:14specify if a variable should be client
- 00:25:15or server we have that too with T3 andv
- 00:25:18but at a framework level that's a really
- 00:25:20nice thing to have you can also
- 00:25:21designate certain variables as Secrets
- 00:25:23like API keys that you would never want
- 00:25:25to have exposed ever so you be real
- 00:25:27strict with like a thing that says that
- 00:25:29as well as specifying if a variable is
- 00:25:31required or just optional which lets you
- 00:25:33catch mistakes before the server is
- 00:25:34booted as well as defining a type of a
- 00:25:37variable like it has to be a string a
- 00:25:38number a URL a URL that matches a
- 00:25:40certain pattern all those types of
- 00:25:42things huge and now you can just import
- 00:25:45strap bbii key from Astro EnV server
- 00:25:48huge A++ I want to see every framework
- 00:25:50copying this Astro 5 is one of the first
- 00:25:53Frameworks to ship with v 6 awesome if
- 00:25:55you already seen my V6 video probably
- 00:25:57worth checking out because the changes
- 00:25:58are very relevant here they've been
- 00:26:00working on the beta versions of V for a
- 00:26:02while so it's not like they just rushed
- 00:26:04to this they've been playing with the
- 00:26:05new v 6 and environment API stuff for a
- 00:26:07bit now it's just ready to go the
- 00:26:09highlight of V6 is the environment API
- 00:26:11which as I said talk about a bunch in
- 00:26:13the video tldr so makes it easier to
- 00:26:14determine how the code runs at different
- 00:26:16places different environments be it Edge
- 00:26:18node pre-render with build client side
- 00:26:21all the above much more flexibility
- 00:26:23there they're excited because they think
- 00:26:25they can get better compatibility with
- 00:26:26things like Cloud flare and other Edge
- 00:26:27run times as well as running those
- 00:26:29locally awesome I'm into it o responsive
- 00:26:32images and SVG let's see what they have
- 00:26:34here for us image cropping support that
- 00:26:37is interesting I haven't seen any
- 00:26:39framework do this where when you set a
- 00:26:42fit with a width and height it crops out
- 00:26:45the things that don't fit so you don't
- 00:26:46have to send the whole image just to
- 00:26:48render a bit of it so let's say this
- 00:26:49image was a th000 by a th000 and we told
- 00:26:51it to do 200 x 200 it's just going to
- 00:26:53render part of the image but we still
- 00:26:55have to send the whole image Now using
- 00:26:57the sharp plugin on the server they will
- 00:26:59regenerate the image so it only uses the
- 00:27:02parts that are being shown in the UI
- 00:27:04that's awesome that goes way further
- 00:27:06than the next image component does to be
- 00:27:08fair I find the use case of
- 00:27:10intentionally cropping a large asset via
- 00:27:13the way you style it on the client to be
- 00:27:15relatively rare but this is really cool
- 00:27:19next image does not do that no next
- 00:27:20image just optimizes the image based on
- 00:27:23the dimensions in the platform it will
- 00:27:25resize the image but it won't crop the
- 00:27:27crop is the difference here they also
- 00:27:30added a responsive layout getting
- 00:27:31responsive images using these optimized
- 00:27:33image components is obnoxious when they
- 00:27:35resize themselves based on the space you
- 00:27:37never really know how big it's going to
- 00:27:38end up being so you don't know what
- 00:27:39sizes to render it at apparently they
- 00:27:41have the ability to predefine responsive
- 00:27:43image layouts they'll automatically
- 00:27:45generate the proper Source set and sizes
- 00:27:46values to make your images look good and
- 00:27:48perform well on all devices so if you
- 00:27:50say layout responsive when it sees which
- 00:27:53devices this can render on it will do
- 00:27:54scaled versions of the image based on
- 00:27:56that awesome
- 00:27:58experimental SVG component did you ever
- 00:28:01wish it was easier to use svgs in
- 00:28:03Astro I've been to Hell in back I've
- 00:28:07been so far to Hellen back for this yeah
- 00:28:10I'm happy that this made it in funny
- 00:28:12enough SVG support was one of like the
- 00:28:14earliest cool things in create react app
- 00:28:16as well as in webpack and because
- 00:28:18webpack didn't have a core feature for
- 00:28:20it we all did it in our own weird
- 00:28:22increasingly hacky ways I'm happy we've
- 00:28:24learned from our mistakes and now we
- 00:28:26have it in Astro V5 cuz if they had done
- 00:28:28this even in one or two they might have
- 00:28:30done it wrong CU we were all doing it
- 00:28:32wrong at the time looks like you can
- 00:28:34just import an SVG and use it like a
- 00:28:36component and it just works now awesome
- 00:28:38A+
- 00:28:41overdue obviously there's bug fixes in
- 00:28:43more but what's most important is how
- 00:28:46well can I upgrade this in my code base
- 00:28:50here is t3.8
- 00:28:58I am very curious what happens when I
- 00:29:00update
- 00:29:07itol I'm I'm curious what version I'm
- 00:29:10running right now because I up until
- 00:29:12like last year I think I was on the pre
- 00:29:161.0 of Astro and I did the update to
- 00:29:18three and it just kind of worked when's
- 00:29:20the the history on this I think I
- 00:29:22uninstalled the plugin that tells me I
- 00:29:24uninstalled git lens so I can easily see
- 00:29:27I kind on GitHub though apparently I
- 00:29:29didn't upgrade in order to fix something
- 00:29:30that was broken in Safari last year but
- 00:29:33before then it had been 2 years so I'm
- 00:29:35not like actively updating the version
- 00:29:37of Astro I'm using so let's see how well
- 00:29:39it does two major jumps every things up
- 00:29:42to date have fun
- 00:29:44building bets on if this works first try
- 00:29:47browser list is outdated that's fine
- 00:29:49I'll fix that in a sec it looks like it
- 00:29:51just worked do view transitions still
- 00:29:53work it looks like they do oh that's so
- 00:29:56good that's that's so good I need to
- 00:29:59post on my blog more it's been a minute
- 00:30:01as. glob is deprecated it will be
- 00:30:03removed in a future major version use
- 00:30:05import. meta duck glob instead let's see
- 00:30:07if I just swap that if it's
- 00:30:11fine now the errors are starting oh it
- 00:30:14comes through as a record now also
- 00:30:17prettier is failing of course it is did
- 00:30:20it not update the prettier plugin why
- 00:30:22wouldn't it update that as part of the
- 00:30:23update process also like like I know
- 00:30:27Astro guys you don't want to like bet on
- 00:30:29prettier you should it is such a bad
- 00:30:32experience to not have formatting now
- 00:30:35that it's just it should be deeply
- 00:30:38considered in your templates especially
- 00:30:40with Tailwind like if you're using
- 00:30:41tailwind and you're not using the
- 00:30:43prettier plugin for Tailwind you're
- 00:30:45using Tailwind wrong and it's not just
- 00:30:47like suboptimal DX but your users are
- 00:30:48getting a worse experience because
- 00:30:50things can't be gzipped as well if the
- 00:30:52classes aren't in the right order nope
- 00:30:53still getting a prettier error it's cuz
- 00:30:56of the Tailwind plugin again like like
- 00:30:58these are the things that it it seems
- 00:31:01scary to update those plugins cuz
- 00:31:02they're not Astros plugins I think it's
- 00:31:05important let's see still
- 00:31:11erroring I have to change the prti your
- 00:31:14plugin Astro to use a dynamic import why
- 00:31:17is this my
- 00:31:19problem cool can I get prettier
- 00:31:23working I did it I did it by moving off
- 00:31:26of a JS prettier config which I had to
- 00:31:28have because Astro didn't support the
- 00:31:31standard config at the time and now it
- 00:31:32does but nothing indicated that the CLI
- 00:31:35should have told me fixed I did it
- 00:31:37Reddit updated to
- 00:31:40latest Astro look at that whole thing
- 00:31:43built in 16 seconds 24 total to for the
- 00:31:46deploy and everything and my site is now
- 00:31:49running Astro 5.0 not that you would
- 00:31:52notice as the user because the site is a
- 00:31:55static HTML site there is really nothing
- 00:31:57astroe being loaded Beyond a tiny bit of
- 00:32:00JS in order to make page Transitions and
- 00:32:02view transitions work here we
- 00:32:05are pretty cool I am very happy with
- 00:32:08this release even if I had to fight
- 00:32:09prettier I'm sure they'll smooth that
- 00:32:10out after seeing this so uh check the
- 00:32:12pinned comment I'm going to leave an
- 00:32:14update once I know if they fixed that or
- 00:32:16not not that it's their problem but
- 00:32:18Astro loves to solve things that aren't
- 00:32:20their problems so fingers crossed that's
- 00:32:22all I got for now let me know what you
- 00:32:23think and how hyped you are for Server
- 00:32:25Islands I know this is a really cool
