Simple React Snippets for VS Code that you will actually use

Simple React Snippets

The essential collection of React Snippets and commands.

Features

Only what you need and nothing more. No Redux. No React Native.

Simply, simple React snippets.

These snippets were selected carefully from my own day-to-day React use. Not everything in React is included here. This is a hand selected set of snippets that work the way that you would expect, not just a copy of the documentation.

cc - Class Component

class | extends React.Component {
  render() {
    return <div>|</div>
  }
}

export default |;

ccc - Class Component With Constructor

class | extends Component {
  constructor(props) {
    super(props);
    this.state = { | };
  }
  render() {
    return ( | );
  }
}

cpc - Class Pure Component

class | extends PureComponent {
  state = { | },
  render() {
    return ( | );
  }
}

export default |;

ffc - Function Component

function (|) {
    return ( | );
}

export default |;

sfc - Stateless Function Component (Arrow function)

const | = props => {
  return ( | );
};

export default |;

cdm - componentDidMount

componentDidMount() {
  |
}

uef - useEffect Hook

useEffect(() => {
  |
}, []);

cwm - componentWillMount

//WARNING! To be deprecated in React v17. Use componentDidMount instead.
componentWillMount() {
  |
}

cwrp - componentWillReceiveProps

//WARNING! To be deprecated in React v17. Use new lifecycle static getDerivedStateFromProps instead.
componentWillReceiveProps(nextProps) {
  |
}

gds - getDerivedStateFromProps

static getDerivedStateFromProps(nextProps, prevState) {
  |
}

scu - shouldComponentUpdate

shouldComponentUpdate(nextProps, nextState) {
  |

ssf - Functional setState

this.setState(prevState => {
  return { | : prevState.| }

}

export default |;

hoc - Higher Order Component

function | (|) {
  return class extends Component {
    constructor(props) {
      super(props);
    }

    render() {
      return < | {...this.props} />;
    }
  };
}

cpf - Class Property Function

  | = (e) => {
    |
  }

Commands

React: class to className

Changes all occurences of class in JSX to className. This transform is safe to run multiple times on any document. No text needs to be selected as the command is executed on the entire document.

Thank You! ❤️

While I wrote the initial version of this extension, many people (too many to name) have helped make it what it is today. From providing TypeScript definitions to keeping up with changing API and best practices. If you are enjoying this extension, you have the great React community to thank.
