Development setup

Make sure that Node.js (at least version 12) is installed.
Install all development dependencies with npm install.

Run tests or type tests in watch mode:

npm run test:watch
npm run type-test:watch

Before you commit, run all following commands to ensure that all tests pass:

npm run test
npm run type-test
npm run lint
npm run build

When adding a new prop type, you need to modify several files:

src/prop-types/yourNewPropType.ts (in camelCase please!) – the implementation.
src/index.ts – re-export the new prop type from the main entrypoint.
tests/prop-types/yourNewPropType.spec.ts – the unit tests.
type-tests/prop-types/yourNewPropType.type.spec.ts – the type tests.

Please use the existing files as a reference and follow the existing style.
