@matane/extension-runtime

The sandbox that runs Matane extensions: a QuickJS runtime per extension with memory, CPU and time limits, the host globals (http through the embedder, which decides what it may reach, html parsed on the host, storage, crypto…), plus the host side of repositories (ed25519 signatures, archives) and of transformImage (tiles rebuilt with sharp).

The Matane app and @matane/extension-cli both use it, so an extension behaves the same in mr-ext test, in its tests and in the app. You normally only need it in extension tests:

import { ExtensionRuntime } from '@matane/extension-runtime';
import { buildExtension, createFixtureHost } from '@matane/extension-cli';

const built = await buildExtension('.', { write: false });
const runtime = await ExtensionRuntime.create({
  code: built.code,
  manifest: built.manifest,
  host: createFixtureHost({ dir: 'test/fixtures' }),
  hostInfo: { appName: 'test', appVersion: '0', apiVersion: 1 },
});
const popular = await runtime.call('en', 'getPopular', [1]);

Subpaths: /repo (index signing and verification, archive reading), /image (restoreImage, applyTiles, sniffImageType), /http-bridge. MIT.
