Theia Sample Plugins

A small collection of minimal VS Code extensions used by Theia to exercise the plugin runtime. Each plugin lives under sample-namespace/ and registers a simple Hello from <plugin-name> command. Some demonstrate specific runtime variants (browser-only, ESM, etc.).

Test sample plugin in Theia example applications

Two options:

A) Copy the plugin folder into the deployed plugins directory

1. Optional: download the bundled VS Code built-ins via npm run download:plugins.

2. Copy the plugin into the deployed plugins directory:

   shCopy

   cp -r sample-plugins/sample-namespace/<plugin-name> plugins/
   

3. Start the example app, e.g.:

   shCopy

   npm run start:browser
   

4. Open the command palette and run Hello from <plugin-name>.

B) Install from the Extensions view

1. Package the plugin as a .vsix. From inside the plugin folder:

   shCopy

   npm run build
   

   This runs vsce package --no-dependencies and produces a <plugin-name>-<version>.vsix next to the source files.

2. Start Theia, e.g. npm run start:browser.

3. Open the Extensions view.

4. Use the ... menu and pick Install from VSIX..., then select the built .vsix.

5. Open the command palette and run Hello from <plugin-name> to verify.
