This project uses GitHub Actions for automated releases:
- Build & Test: Runs on every push to validate code
- Release: Creates releases automatically when tags are pushed
- Version Tagging: Uses semantic versioning (MAJOR.MINOR.PATCH)
# Patch release (bug fixes)
npm run version:patch
# Minor release (new features)
npm run version:minor
# Major release (breaking changes)
npm run version:major
# Push the tag
git push origin v1.2.1This triggers the GitHub Actions workflow to:
- Build the extension
- Run all tests
- Create a GitHub release
- Upload the extension package (
.zip) - Create a version tag
