VS Code Extension Samples is a collection of sample code illustrating the VS Code extension API.

The repository addresses the challenge of learning how to build VS Code extensions by providing self-contained, focused examples that each demonstrate a single topic within the VS Code API or contribution points. Each sample includes an explanation of its functionality, visual demonstrations, links to relevant guides, and a listing of the specific API methods and contribution points it uses. Developers can read, modify, or adapt these samples as starting points for their own extensions.

The samples are written in TypeScript with consistent style enforced through ESLint, and they follow a standard setup pattern: clone the repository, open a sample folder in VS Code, run npm install, and press F5 to execute. The collection includes foundational examples such as Hello World samples in different variants—a standard TypeScript version, a minimal JavaScript version, a version with integration tests, and a web extension version—along with additional samples covering other API topics. This repository is most useful for developers new to VS Code extension development who want concrete, working examples before diving into the full API documentation, or for those seeking to understand how specific API features are implemented in practice.

The project maintains a steady stream of sample additions and updates, with samples consistently demonstrating current API patterns and best practices. Code quality is actively managed through linting standards applied across all examples. Documentation within each sample is kept current with corresponding guides on the VS Code website, ensuring that examples remain aligned with official extension development practices.
