Welcome to your VS Code Extension

What's in the folder

This folder contains all of the files necessary for your web extension.
package.json - this is the manifest file in which you declare your extension and command.
src/web/extension.ts - this is the main file for the browser
webpack.config.js - the webpack config file for the web main

Setup

install the recommended extensions (eamodio.tsl-problem-matcher and dbaeumer.vscode-eslint)

Get up and running the Web Extension

npm install
place breakpoints in src/web/extension.ts
debug via F5 (Run Web Extension)
execute extension code via F1 > Hello world

Make changes

You can relaunch the extension from the debug toolbar after changing code in src/web/extension.ts.
You can also reload (Ctrl+R or Cmd+R on Mac) the VS Code window with your extension to load your changes.

Explore the API

You can open the full set of our API when you open the file node_modules/@types/vscode/index.d.ts.

Run tests

Open the debug viewlet (Ctrl+Shift+D or Cmd+Shift+D on Mac) and from the launch configuration dropdown pick Extension Tests.
Press F5 to run the tests in a new window with your extension loaded.
See the output of the test result in the debug console.
Make changes to src/web/test/suite/extension.test.ts or create new test files inside the test/suite folder.
