'@gnestor/react-components' ~~~ To render a stateless component: ~~~js render(() => button({ onClick: () => { console.log('clicked!') } })) ~~~ To render a stateful component using Observable's \`viewof\` feature, use the \`rendered*\` functions which render the components and use \`useSetter\` to sync the cell's value to the component's value: ~~~js viewof myText = renderedText() ~~~ **Tip:** You can use named aliases to import the \`rendered*\` components: ~~~js import { renderedText as text } from '@gnestor/react-components' ~~~ To compose several components in a form or more complex UI: ~~~js viewof form = render(({ useSetter }) => { const [state, setState] = useState({ button: 0, select: 'one', textarea: '' }); useSetter(state); return [ button({ label: 'Test', onClick: event => { console.log('button', 'Test test'); setState({ ...state, button: state.button + 1 }); } }), select({ options: ['one', 'two', 'three'], setValue: value => { console.log('select', value); setState({ ...state, select: value }); } }), textarea({ setValue: value => { console.log('textarea', value); setState({ ...state, textarea: value }); } }) ]; }) ~~~`2e:T47c,viewof test = render(({ useSetter }) => { const [state, setState] = useState({ button: 0, select: 'one', textarea: '' }); useSetter(state); // return jsx`<${button} label="Test" onClick=${event => { // console.log('button', 'Test test'); // setState({ ...state, button: state.button + 1 }); // }} /><${select} options=${['one', 'two', 'three']} setValue=${value => { // console.log('select', value); // setState({ ...state, select: value }); // }} /><${textarea} setValue=${value => { // console.log('textarea', value); // setState({ ...state, textarea: value }); // }} />`; return [ button({ label: 'Test', onClick: event => { console.log('button', 'Test test'); setState({ ...state, button: state.button + 1 }); } }), select({ options: ['one', 'two', 'three'], setValue: value => { console.log('select', value); setState({ ...state, select: value }); } }), textarea({ setValue: value => { console.log('textarea', value); setState({ ...state, textarea: value }); } }) ]; })2f:[]
