or using pnpm

pnpm i @alessiofrittoli/react-api

Development

Run the following to start development

nvm use

pnpm i

Local development

Run the following

pnpm dev

This will generate unminified output code, sourcemaps and will enable source file watcher.


Production build

Run the following to create a local production build

pnpm build

This will generate minified output code without sourcemaps.


Unit tests

Run all the defined test suites by running the following:

# Run tests and watch file changes.
pnpm test:watch

# Run tests in a CI environment.
pnpm test:ci

Run tests with coverage

An HTTP server is then started to serve coverage files from ./coverage folder.

interface ComponentProps
{
  children?: FunctionChildren<[ state: boolean ]>
}

const Component: React.FC<ComponentProps> = ( { children } ) => {

  const [ state, setState ] = useState( false )
