astro

0.17.0

Minor Changes

• 0a7b6de: ## Adds directive syntax for component hydration

  This change updates the syntax for partial hydration from <Button:load /> to <Button client:load />.

  Why?

  Partial hydration is about to get super powers! This clears the way for more dynamic partial hydration, i.e. <MobileMenu client:media="(max-width: 40em)" />.

  How to upgrade

  Just update :load, :idle, and :visible to match the client:load format, thats it! Don't worry, the original syntax is still supported but it's recommended to future-proof your project by updating to the newer syntax.

0.16.3

Patch Changes

• 5d1ff62: Hotfix for snowpack regression

0.16.2

Patch Changes

• 20b4a60: Bugfix: do not override user alias passed into snowpack config
• 42a1fd7: Add command line flag --silent to astro to set no output.

0.16.1

Patch Changes

• 2d3e369: Fix for using the snowpack polyfillNode option

0.16.0

Minor Changes

• d396943: Add support for remark and rehype plugins for both .md pages and .astro pages using the <Markdown> component.

  For example, the astro.config.mjs could be updated to include the following. Read the Markdown documentation for more information.

  Note

  Enabling custom remarkPlugins or rehypePlugins removes Astro's built-in support for GitHub-flavored Markdown support, Footnotes syntax, Smartypants. You must explicitly add these plugins to your astro.config.mjs file, if desired.

  export default {
    markdownOptions: {
      remarkPlugins: ['remark-slug', ['remark-autolink-headings', { behavior: 'prepend' }]],
      rehypePlugins: ['rehype-slug', ['rehype-autolink-headings', { behavior: 'prepend' }]],
    },
  };
  

Patch Changes

• Updated dependencies [d396943]
• Updated dependencies [f83407e]
  • @astrojs/markdown-support@0.2.0

0.15.5

Patch Changes

• 7b4c97c: Adds support for hydrationPolyfills in renderers

  Renderers can not specify polyfills that must run before the component code runs for hydration:

  export default {
    name: '@matthewp/my-renderer',
    server: './server.js',
    client: './client.js',
    hydrationPolyfills: ['./my-polyfill.js'],
  };
  

  These will still wait for hydration to occur, but will run before the component script does.

0.15.4

Patch Changes

• 6a660f1: Adds low-level custom element support that renderers can use to enable server side rendering. This will be used in renderers such as a Lit renderer.
• Updated dependencies [6a660f1]

0.15.1

Patch Changes

• 8865158: Fixes postcss bug with the 'from' property

0.15.0

Minor Changes

• a136c85: This is a breaking change!

  Astro props are now accessed from the Astro.props global. This change is meant to make prop definitions more ergonomic, leaning into JavaScript patterns you already know (destructuring and defaults). Astro components previously used a prop syntax borrowed from Svelte, but it became clear that this was pretty confusing for most users.

   ---
  + const { text = 'Hello world!' } = Astro.props;
  - export let text = 'Hello world!';
   ---
  
   <div>{text}</div>
  

  Read more about the .astro syntax

  ---

  How do I define what props my component accepts?

  Astro frontmatter scripts are TypeScript! Because of this, we can leverage TypeScript types to define the shape of your props.

  ---
  export interface Props {
    text?: string;
  }
  const { text = 'Hello world!' } = Astro.props as Props;
  ---
  

  Note

  Casting Astro.props as Props is a temporary workaround. We expect our Language Server to handle this automatically soon!

  How do I access props I haven't explicitly defined?

  One of the great things about this change is that it's straight-forward to access any props. Just use ...props!

  ---
  export interface Props {
    text?: string;
    [attr: string]: unknown;
  }
  const { text = 'Hello world!', ...props } = Astro.props as Props;
  ---
  

  What about prop validation?

  We considered building prop validation into Astro, but decided to leave that implementation up to you! This way, you can use any set of tools you like.

  ---
  const { text = 'Hello world!' } = Astro.props;
  
  if (typeof text !== 'string') throw new Error(`Expected "text" to be of type "string" but recieved "${typeof string}"!`);
