# Frontend Style Guidelines
|
|
|
|
This is a list of statements that describe how we do frontend development in Superset. While they might not be 100% true for all files in the repo, they represent the gold standard we strive towards for frontend quality and style.
|
|
|
|
- We develop using TypeScript.
|
|
- See: [SIP-36](https://github.com/apache/superset/issues/9101)
|
|
- We use React for building components, and Redux to manage app/global state.
|
|
- See: [Component Style Guidelines and Best Practices](./frontend/component-style-guidelines)
|
|
- We prefer functional components to class components and use hooks for local component state.
|
|
- We use [Ant Design](https://ant.design/) components from our component library whenever possible, only building our own custom components when it's required.
|
|
- See: [SIP-48](https://github.com/apache/superset/issues/11283)
|
|
- We use [@emotion](https://emotion.sh/docs/introduction) to provide styling for our components, co-locating styling within component files.
|
|
- See: [SIP-37](https://github.com/apache/superset/issues/9145)
|
|
- See: [Emotion Styling Guidelines and Best Practices](./frontend/emotion-styling-guidelines)
|
|
- We use Jest for unit tests, React Testing Library for component tests, and Cypress for end-to-end tests.
|
|
- See: [SIP-56](https://github.com/apache/superset/issues/11830)
|
|
- See: [Testing Guidelines and Best Practices](../testing/testing-guidelines)
|
|
- We add tests for every new component or file added to the frontend.
|
|
- We organize our repo so similar files live near each other, and tests are co-located with the files they test.
|
|
- See: [SIP-61](https://github.com/apache/superset/issues/12098)
|
|
- We prefer small, easily testable files and components.
|
|
- We use OXC (oxlint) and Prettier to automatically fix lint errors and format the code.
|
|
- We do not debate code formatting style in PRs, instead relying on automated tooling to enforce it.
|
|
- If there's not a linting rule, we don't have a rule!
|
|
- See: [Linting How-Tos](../contributing/howtos#typescript--javascript)
|
|
- We use [React Storybook](https://storybook.js.org/) to help preview/test and stabilize our components
|
|
- A public Storybook with components from the `master` branch is available [here](https://apache-superset.github.io/superset-ui/?path=/story/*)
