Visual Studio Code Language Extension Example

In this topic, we'll teach you the fundamental concepts for building extensions. Make sure you have Node.js and Git installed, then install Yeoman and VS Code Extension Generator with:

The generator scaffolds a TypeScript or JavaScript project ready for development. Run the generator and fill out a few fields for a TypeScript project:

Then, inside the editor, press F5. This will compile and run the extension in a new Extension Development Host window.

Run the Hello World command from the Command Palette (⇧⌘P (Windows, Linux Ctrl+Shift+P)) in the new window:

You should see the Hello World from HelloWorld! notification showing up. Success!

Developing the extension

Let's make a change to the message:

Change the message from Hello World from HelloWorld! to Hello VS Code in extension.ts
Run Developer: Reload Window in the new window
Run the command Hello World again

You should see the updated message showing up.

Here are some ideas for you to try:

Give the Hello World command a new name in the Command Palette.
Contribute another command that displays current time in an information message. Contribution points are static declarations you make in the package.json Extension Manifest to extend VS Code, such as adding commands, menus, or keybindings to your extension.
Replace the vscode.window.showInformationMessage with another VS Code API call to show a warning message.

Debugging the extension

VS Code's built-in debugging functionality makes it easy to debug extensions. Set a breakpoint by clicking the gutter next to a line, and VS Code will hit the breakpoint. You can hover over variables in the editor or use the Run view in the left to check a variable's value. The Debug Console allows you to evaluate expressions.

You can learn more about debugging Node.js apps in VS Code in the Node.js Debugging Topic.
