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.

Full Expansions

imr - Import React

import React from 'react';

imrc - Import React, Component

import React, { Component } from 'react';

imrs - Import React, useState

import React, { useState } from 'react';

imrse - Import React, useState, useEffect

import React, { useState, useEffect } from 'react';

impt - Import PropTypes

import PropTypes from 'prop-types';

impc - Import PureComponent

import React, { PureComponent } from 'react';

cc - Class Component

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

export default |;

ccc - Class Component With Constructor

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

export default |;

ccc - Class Component With Constructor

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

export default |;

sfc - Stateless Function Component

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) {
  |
}

cwu - componentWillUpdate

//WARNING! To be deprecated in React v17. Use componentDidUpdate instead.
componentWillUpdate(nextProps, nextState) {
  |
}

cdu - componentDidUpdate

componentDidUpdate(prevProps, prevState) {
  |
}

cwun - componentWillUnmount

componentWillUnmount() {
  |
}

cdc - componentDidCatch

componentDidCatch(error, info) {
  |
}

gsbu - getSnapshotBeforeUpdate

getSnapshotBeforeUpdate(prevProps, prevState) {
  |
}

ss - setState

this.setState({ | : | });

ssf - Functional setState

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

usf - Declare a new state variable using State Hook

const [|, set|] = useState();

Hit Tab to apply CamelCase to function. e.g. [count, setCount]

ren - render

render() {
  return (
    |
  );
}

rprop - Render Prop

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

export default |;

hoc - Higher Order Component

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

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

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.
