Quick start

What's in the folder

This folder contains all of the files necessary for the extension.
package.json - this is the manifest file in which you declare the extension and command.
- The sample plugin registers a command and defines its title and command name. With this information VS Code can show the command in the command palette. It doesn’t yet need to load the plugin.
src/extension.ts - this is the main file where you will provide the implementation of the command.
- The file exports one function, activate, which is called the very first time the extension is activated (in this case by executing the command). Inside the activate function we call registerCommand.
- We pass the function containing the implementation of the command as the second parameter to registerCommand.

Press F5 to open a new window with the extension loaded.
Run the command from the command palette by pressing (Ctrl+Shift+P or Cmd+Shift+P on Mac) and typing Hello World.
Set breakpoints in the code inside src/extension.ts to debug the extension.
Find output from the extension in the debug console.

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

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

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 the extension loaded.
See the output of the test result in the debug console.
Make changes to test/extension.test.ts or create new test files inside the test folder.
- By convention, the test runner will only consider files matching the name pattern **.test.ts.
- You can create folders inside the test folder to structure the tests any way you want.

Reduce the extension size and improve the startup time by bundling the extension.
Publish the extension on the VSCode extension marketplace.
Automate builds by setting up Continuous Integration.
