Integrations guide
Connect Extension.js with formatting, linting, CSS tooling, and UI component workflows used in modern web projects.
Choose by need
| Need | Start here |
|---|---|
| Add custom transforms beyond SWC | Babel |
| Enforce code-quality rules | ESLint |
| Keep formatting consistent | Prettier |
| Transform CSS with plugins | PostCSS |
| Lint stylesheets in CI | Stylelint |
| Build composable UI primitives | Shadcn/ui |
| Utility-first styling system | Tailwind CSS |
Practical integration order
- Add baseline quality tools: ESLint + Prettier.
- Add style tooling: PostCSS + Stylelint (and Tailwind if needed).
- Add framework-specific tooling only when required.
Next steps
- Align project defaults in Extension config.
- Validate changes with Workflows.
