Contributing to React Native Paper

We want this community to be friendly and respectful to each other. Please read the full text so that you can understand what actions will and will not be tolerated.

Our Development Process

The core team works directly on GitHub and all work is public.

Development workflow

Working on your first pull request? You can learn how from this free series: How to Contribute to an Open Source Project on GitHub.

  1. Fork the repo and create your branch from master (a guide on how to fork a repository).
  2. Run yarn bootstrap to setup the developement environment.
  3. Do the changes you want and test them out in the example app before sending a pull request.

Commit message convention

We prefix our commit messages with one of the following to signify the kind of change:

  • fix: bug fixes, e.g. fix Button color on DarkTheme.
  • feat: new features, e.g. add Snackbar component.
  • refactor: code/structure refactor, e.g. new structure folder for components.
  • docs: changes into documentation, e.g. add usage example for Button.
  • test: adding or updating tests, eg unit, snapshot testing.
  • chore: tooling changes, e.g. change circle ci config.
  • BREAKING: for changes that break existing usage, e.g. change API of a component.

Our pre-commit hooks verify that your commit message matches this format when committing.

Linting and tests

We use flow for type checking, eslint with prettier for linting and formatting the code, and jest for testing. Our pre-commit hooks verify that the linter and tests pass when commiting. You can also run the following commands manually:

  • yarn flow: run flow on all files.
  • yarn lint: run eslint and prettier.
  • yarn test: run tests.

Sending a pull request

When you're sending a pull request:

  • Prefer small pull requests focused on one change.
  • Verify that flow, eslint and tests are passing.
  • Preview the documentation to make sure it looks good.
  • Follow the pull request template when opening a pull request.

When you're working on a component:

  • Follow the guidelines described in the official material design docs.
  • Write a brief description of every prop when defining type Props to aid with documentation.
  • Provide an example usage for the component (check other components to get a idea).

Running the example

The example app uses Expo. You will need to install the Expo app for Android and iOS to start developing.

After you're done, you can run yarn start in the example/ folder and scan the QR code to launch it on your device.

Working on documentation

The documentation is automatically generated from the flowtype annotations in the components. You can add comments above the type annotations to add descriptions. To preview the generated documentation, run yarn start in the docs/ folder.

Reporting issues

You can report issues on our bug tracker. Please follow the issue template when opening an issue.
