PRs are welcome! Make sure, to add tests for your changes and run npm test before submitting a PR.
We are using jest for testing. See Jest CLI Options for more information.
To run all tests, use npm test. This will execute tests for all supported react versions.
To run tests only for a single react version, use npm test -- --selectProjects react-16.
You can link the package to your project by running npm link && npm run dev in the shallow-react-snapshot project and npm link shallow-react-snapshot in your project. The npm run dev will watch for changes in the shallow-react-snapshot project and rebuild the package.
When investigating react internals, it is often helpful to have a playground to test things out and check them directly in the browser.
Run npm run playground to open a server with a simple react component (you will be able to select the version). You can edit the rendered react component in playground/main.jsx file if you want to simulate a specific scenario.
We are using biome for code formatting and linting.
Run npm run lint to check for formatting / linter issues in your code.
Run npm run lint:fix to fix formatting / linter issues in your code.
Run npm run lint:fix:unsafe to fix formatting / linter issues in your code including unsafe fixes.
