Build VSCode Extensions

This repo has one VSCode extension component:

Component	Location	What it is
dart_node_vsix	`packages/dart_node_vsix/`	The SDK package — Dart bindings for the VSCode extension API (commands, tree views, webviews, status bar, etc.)

dart_node_vsix SDK package

Test the SDK (Dart tests compiled to JS, run in VSCode):

cd packages/dart_node_vsix && npm install && npm run compile && npm test

What it provides — Dart bindings for:

commands, window, workspace, statusBar
TreeView, Webview, OutputChannel
ExtensionContext, Disposable
Mocha test API bindings
JS interop helpers (Promise, EventEmitter)

Architecture

Both use the same pattern: Dart → dart compile js → wrapper script → VSCode-compatible JS module.

The wrapper scripts (scripts/wrap-extension.js, scripts/wrap-tests.js) bridge dart2js output to VSCode's CommonJS require/module.exports system and inject polyfills (navigator, self) needed by dart2js async scheduling.
