The best way to structure a VS Code extension is to separate activation, commands, panels, providers, and services into a clean architecture that enforces maintainability and scalability. This opinionated structure ensures clear boundaries between UI components and business logic, simplifying long-term development.

To publish a .vsix file via GitHub Actions, configure a CI/CD pipeline using vsce for packaging and secure release workflows for marketplace publishing. This approach automates extension deployment securely, ensuring consistent versioning and distribution directly from your repository.

To secure WebViews in VS Code, apply strict Content Security Policy (CSP) rules, use nonces for script execution, and follow accessibility patterns for web content. These practices prevent malicious code injection and ensure the extension's UI remains safe for all users.

Yes, you can audit existing VS Code extensions by reviewing them against established directives for project structure, TypeScript strict mode, and Vitest tests. This process identifies architectural flaws and enforces best practices during refactoring to improve overall code quality.

Yes, this guidance enforces TypeScript strict mode and integrates Vitest tests to ensure professional-quality code and robust test coverage. Adopting these tools helps catch type errors early and provides a reliable testing framework for commands and language providers.
