AssemblyScript's Website

The site is built with VuePress and reuses its default theme to ease upgrading to newer versions.

The more important files are:

• src/**/*.md
  Documentation and site contents, i.e. what one would typically modify when extending the documentation.
• src/.vuepress/sidebar.js
  Sidebar contents.
• src/.vuepress/nav.js
  Top-navigation contents.
• src/.vuepress/redirects
  Redirect map of (re)moved pages to new locations.
• src/.vuepress/public/
  Assets folder for images etc.
• src/.vuepress/public/sponsors
  Sponsor logo overrides (file name is collective name).

Editor component

Markdown files can make use of a custom editor component using the editor language tag, like so:

```editor
#!optimize=size&runtime=none&noAssert&explicitStart&enable=simd,reference-types
export function add(a: i32, b: i32): i32 {
  return a + b
}

#!html
<script type="module">
const exports = await instantiate(await compile(), { /* imports */ })
console.log(exports.add(1, 2))
</script>
```

The first line is an optional shebang indicating selected compiler options. Available options are:

• optimize = string
  Optimization preset to use. Valid presets are speed, size and none
• noAssert
  Replaces assertions with just their value without trapping.
• debug
  Enables debug information in emitted binaries.
• runtime = string
  Specifies the runtime variant to include in the program. Valid variants are full, half, stub and none.
• noExportMemory
  Does not export the memory to the host.
• importMemory
  Imports the memory from the host.
• exportTable
  Exports the function table to the host.
• importTable
  Imports the function table from the host.
• explicitStart
  Exports an explicit start function to call.
• memoryBase = integer
  Sets the start offset of emitted memory segments.
• tableBase = integer
  Sets the start offset of emitted table elements.
• use = string
  Comma separated list of global aliases, e.g. to switch the default 'Math' implementation used: Math=JSMath
• enable = string
  Comma-separated list of future WebAssembly features to enable. Valid features are sign-extension, bulk-memory, simd, threads and reference-types.

The current source and associated compiler options can be serialized into a base64 blob this way. For example, when the 🔗 button is clicked, document.location.hash is updated with that blob and the then-sharable link is copied to clipboard.

Building

To work on the site locally, install the dependencies and start a development server serving at localhost:8080:

npm install
npm start

To build the site to dist, i.e. to verify that it works as expected:

npm run build

Distribution files can also be served instead of using the development server with:

npm run serve

The page is automatically deployed on pushes to the repository, plus at least once a day to sync contributors and sponsors.
