v0.20.0

ECMAScript modules

Fixes #1306. Migrating our dependencies to ESM made it possible to migrate the compiler and frontend as well, alongside internal utility and scripts. This is a breaking change for consumers of the compiler API (i.e. transforms), but not for command line usage. Viable strategies to account for the changes are:

1. Migrate any code utilizing compiler APIs to ESM as well:

   import assemblyscript from "assemblyscript";
   ...

2. Utilize a dynamic import while consuming code remains in its current module format:

   const assemblyscript = (await import("assemblyscript")).default;
   ...
   // or
   import("assemblyscript").then(({ default: assemblyscript }) => { ... });

Due to this change, older versions of Node.js may need to be upgraded (LTS v16 or stable v17 are recommended).

Running the compiler on the Web with ESM

Prior, we provided a browser SDK that made use of the AMD module format to load the components necessary to run the compiler on the Web. With the switch to ESM, it is not necessary anymore to provide a separate SDK, but native browser functionality can now be used to utilize the compiler in browsers. To ease the transition, the build system outputs an example dist/web.html template with all the right versions in <script ...> tags. Alongside, it also sets up es-module-shims for import maps support as is currently necessary to support browsers other than those based on Chromium. General outline is:

<script async src="url/to/es-module-shims"></script>
<script type="importmap">
{
  "imports": {
</tr></table> 

... (truncated)
