--description--
Agora que você aprendeu os conceitos básicos de componentes JSX e React, é hora de escrever um componente por conta própria. Componentes do React são os blocos centrais de construção de aplicações React, por isso é importante se familiarizar com a escrita. Lembre-se, um componente típico do React é uma class
do ES6 que estende React.Component
. Ele possui um método de renderização que retorna HTML (a partir de JSX) ou null
. Essa é a forma básica de um componente do React. Assim que você entender bem, você estará preparado para começar a construir projetos mais complexos em React.
--instructions--
Define uma classe MyComponent
que estende React.Component
. Seu método de renderização deve retornar uma div
que contém uma tag h1
com o texto: My First React Component!
nela. Use este texto exatamente, letras maiúsculas e minúsculas, e pontuação importam. Certifique-se de chamar o construtor para seu componente também.
Renderize este componente para o DOM usando ReactDOM.render()
. Há um div
com id='challenge-node'
disponível para você usar.
--hints--
Deve haver um componente React chamado MyComponent
.
(getUserInput) =>
assert(
__helpers
.removeWhiteSpace(getUserInput('index'))
.includes('classMyComponentextendsReact.Component{')
);
MyComponent
deve conter uma tag h1
com texto My First React Component!
Letras maiúsculas e minúsculas, e pontuação importam.
assert(
(function () {
const mockedComponent = Enzyme.mount(React.createElement(MyComponent));
return mockedComponent.find('h1').text() === 'My First React Component!';
})()
);
MyComponent
deve existir e ser rendizado no DOM.
assert(document.getElementById('challenge-node').childNodes.length === 1);
MyComponent
deve ter um construtor chamando super
com props
.
assert(
MyComponent.toString().includes('MyComponent(props)') &&
MyComponent.toString().includes('_super.call(this, props)')
);

class MyComponent extends React.Component {
constructor(props) {
super(props);
}
render() {
return (
<div>
<h1>My First React Component!</h1>
</div>
);
}
};
ReactDOM.render(<MyComponent />, document.getElementById('challenge-node'));
