SSR discovery

00explainer.md

Table of contents

Goals

  • Produce an SSR build that can be run without dependencies on Vite.
  • Use SSR build to power static-generation.
  • SSG should happen in a single-pass (no post-processing HTML after generation).
Raw
example-01.md 
<!-- Global CSS -->
<link rel="stylesheet" href={Astro.resolve('../styles/theme.css')} />
<link rel="stylesheet" href={Astro.resolve('../styles/code.css')} />
<link rel="stylesheet" href={Astro.resolve('../styles/index.css')} />

Becomes:

<!-- Global CSS -->
<link
  rel="stylesheet"
  href="/src/styles/theme.css"
/>
<link
  rel="stylesheet"
  href="/src/styles/code.css"
/>
<link
  rel="stylesheet"
  href="/src/styles/index.css"
/>

Question

  • Should these be bundled?

Solution

  • Needs @component static solution.
  • Overload Astro.resolve when generating the HTML.
  • If bundling, the compiler needs to turn this into an expression of some sort, so that we can control if this gets rendered.
Raw
example-02.md 
<style>
  .layout {
    display: grid;
    grid-auto-flow: column;
    grid-template-columns: 
      minmax(var(--gutter), 1fr) 
      minmax(0, var(--max-width)) 
      minmax(var(--gutter), 1fr);
    overflow-x: hidden;
  }
</style>
<style> /* ... */ </style>

Becomes:

<style astro-style="true">
  .layout.astro-4B45IKYD {
    display: grid;
    grid-auto-flow: column;
    grid-template-columns: minmax(var(--gutter), 1fr) minmax(
        0,
        var(--max-width)
      ) minmax(var(--gutter), 1fr);
    overflow-x: hidden;
  }
</style>
<style astro-style="true">
  header.astro-XSR2FY3G {
    z-index: 11;
    height: var(--theme-navbar-height);
    width: 100%;
    background-color: var(--theme-navbar-bg);
    display: flex;
    align-items: center;
    justify-content: center;
    overflow: hidden;
    position: sticky;
    top: 0;
  }
 </style>

Solution

  • These are rendered by $$result.styles
    • Add a $$result.links that gets passed in instead.
    • Some type of route configuration file maybe:
    {
  "/introduction": {
    "module": "dist/assets/introduction.hash.mjs",
    "links": [
      { "rel": "stylesheet": "href": "../assets/introduction.hash.css" }
    ]
  }
}
Raw
example-03.md

This JSX (relevant for any framework component):

import './Search.css';

export default Search() {
  return <div class="search"> ... </div>
}

Does not get rendered

This relies on HTML post-processing and depends on the Vite module graph.

Solution

  • These CSS should be built out during vite.build.
  • They will be added via the route configuration.
Raw
example-04.md

This Astro usage:

<ThemeToggleButton client:visible />

Gets generated as:

<script
  type="module"
  data-astro-component-hydration
  astro-script="/en/introduction/script-2"
>
  import setup from "astro/client/visible.js";
  setup("Z23uxs3", { value: true }, async () => {
    const [{ default: Component }, { default: hydrate }] =
      await Promise.all([
        import(
          "/src/components/ThemeToggleButton.tsx"
        ),
        import("@astrojs/renderer-preact/client.js"),
      ]);
    return (el, children) =>
      hydrate(el)(
        Component,
        {
          class: "astro-WUQUYG3V",
        },
        children
      );
  });
</script>

Questions

  • Is client:visible allowed to be dynamic?

Problems

  • This relies on runtime to know that @astrojs/renderer-preact/client.js is used.
  • If client:visible is dynamic, relies on runtime to know that astro/client/visible.js is used.
  • Given that renderers are discovered at runtime, bundling these inline scripts head of time seems impossible. This is probably ok.

Solution

  • Make client:visible, etc static, so we know which are needed.
  • Create an entrypoint for astro/client/visible.js.
  • For each renderer listed in astroConfig.renderers, create an entrypoint. This will mean it's available if needed at runtime.
  • Create a mapping of directives to their final built file in the route configuration.
  • Create a mapping of renderers to their final built file in the route configuration.
Raw
example-05.md

This Astro:

<script type="module" src={Astro.resolve('./script.js')} hoist></script>

Gets generated as:

<script
  type="module"
  src="/src/components/script.js"
  hoist="true"
  astro-script="/en/introduction/script-0"
></script>

Solution

  • Needs a @component like solution to ensure static.
  • Make this part of the route configuration like with stylesheet links.
Raw
example-06.md

Astro:

<img src={Astro.resolve('../images/twitter.png')} />

Generates this HTML:

<img src="/src/images/twitter.png" class="astro-QY234LXS">

Solution

  • Needs the @component type of solution.
Raw
example-07.md

Astro:

<img srcset={`${Astro.resolve('../images/twitter.png')} 1x,
  ${Astro.resolve('../images/[email protected]')} 2x,
  ${Astro.resolve('../images/[email protected]')} 3x`} />

Generates this HTML:

<img srcset="/src/images/twitter.png 1x, /src/images/[email protected] 2x, /src/images/[email protected] 3x" class="astro-QY234LXS">

Solution

  • Needs the @component type of solution.
Raw
example-08.md

This Astro (or JSX):

---
import imgUrl from '../images/twitter.png';
---

<img src={imgUrl} />

Will render:

<img src="/src/images/twitter.png" class="astro-QY234LXS">

Solution

We should be able to make this be hashed and included in dist. This way we don't need to make any changes to the template.

            <p>
              This is the <code data-astro-raw>docs</code> starter template. It
              contains all of the features that you need to build a
              Markdown-powered documentation site, including:
            </p>
            <ul>
              <li>✅ <strong>Full Markdown support</strong></li>
              <li>✅ <strong>Responsive mobile-friendly design</strong></li>
              <li>✅ <strong>Sidebar navigation</strong></li>
              <li>✅ <strong>Search (powered by Algolia)</strong></li>
              <li>✅ <strong>Multi-language i18n</strong></li>
              <li>✅ <strong>Automatic table of contents</strong></li>
              <li>✅ <strong>Automatic list of contributors</strong></li>
              <li>✅ (and, best of all) <strong>dark mode</strong></li>
            </ul>
            <h2 id="getting-started">Getting Started</h2>
            <p>
              To get started with this theme, check out the
              <code data-astro-raw>README.md</code> in your new project
              directory. It provides documentation on how to use and customize
              this template for your own project. Keep the README around so that
              you can always refer back to it as you build.
            </p>
            <p>
              Found a missing feature that you can’t live without? Please

              >
              and even consider adding it yourself on GitHub! Astro is an open
              source project and contributions from developers like you are how
              we grow!

Looks great! A couple of quick thoughts:

  • I posted this comment last night in Jonathan's resolution RFC discussion and I think it's relevant here. Basically, I can't see a way that Astro.resolve() can continue to exist in a post-SSR world. I think @JonathanNeal might be tackling that in his RFC, and leaning more heavily on ESM imports for assets, which could be a great solution to the resolution problems that you're trying to solve here. We should all get together to chat.
  • If you're starting to get blocked by the lack of @component support, I'm happy to start pushing the core team to prioritize that discussion and even get high-level buy-in going into that RFC call. At least to the point where you could assume that something like it exists for you to use here.
  • I'm on board with adding the requirement that all directives are statically analyzable in the template. Basically, that <Component {...{'client:load': true}} /> is not supported and would result in a runtime error. The value of the directive could still be dynamic if needed, to support something like <Component client:visible={someVal} />.
