Build VSCode Extensions

This repo has two VSCode extension components:

ComponentLocationWhat it is
dart_node_vsixpackages/dart_node_vsix/The SDK package — Dart bindings for the VSCode extension API (commands, tree views, webviews, status bar, etc.)
too_many_cooksexamples/too_many_cooks_vscode_extension/A concrete extension built with that SDK — multi-agent coordination UI

too-many-cooks extension

Full build (MCP server + extension + .vsix package):

bash
bash examples/too_many_cooks_vscode_extension/build.sh

This does:

  1. •Compiles MCP server: dart compile js → add_preamble.dart → server_node.js
  2. •Compiles extension: dart compile js → wrap-extension.js bridge → out/lib/extension.js
  3. •Packages: vsce package → .vsix file

Test (runs Mocha tests under a real VSCode instance):

bash
cd examples/too_many_cooks_vscode_extension && npm run pretest && npm test

On headless Linux, prefix with xvfb-run -a.

Install into VSCode:

bash
code --install-extension examples/too_many_cooks_vscode_extension/*.vsix

dart_node_vsix SDK package

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

bash
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.
