JS - Snippet Good!

Newest Release: v1.7.0 - Typescript Support!

---

Features

A collection of customized snippets intended for personal use. I've gathered and modified some of them from existing packages and created the rest.

Example (rfpe and ptsr snippets)

Supported VS Code Language Extensions

• javascript (.js)
• javascriptreact (.jsx)
• typescript (.ts)
• typescriptreact (.tsx)
• css (styled component shortcuts)

Debugging developer note:

If you are working on this extension, you can use the F5 key to enter debugging mode and use the snippets you are adding/modifying in any project you like.

Snippets

cl – console log

console.log()

---

clc – console log with color

note: cursor starts at your message, first tab goes to color, third tab goes to the position after the css string, so you can add additional variables to log.

console.log('%cYourTextHere', 'color: cornflowerblue;')

---

clg – console log group

note: the string passed to .group and .groupEnd should be the same

console.group("Group Name");
console.log("I am in the group!");
console.groupEnd("Group Name");

---

imp – import module

import module from 'module'

---

imd – import module destructured

import { moduleName } from 'module'

---

imr – import react

import React from 'react'

---

imrc – import react and Component

import React, { Component } from 'react'

---

imrpc – import react and PureComponent

import React, { PureComponent } from 'react'

---

imrus – import react and useState

import React, { useState } from 'react'

---

imrue – import react and useEffect

import React, { useEffect } from 'react'

---

imruse or imrues – import react, useState and useEffect

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

---

impt – import PropTypes

import PropTypes from 'prop-types'

---

imes – import enzyme's shallow module

import { shallow } from 'enzyme'

---

imem – import enzyme's mount module

import { mount } from 'enzyme'

---

imesm – import enzyme's shallow and mount modules

import { shallow, mount } from 'enzyme'

---

exp – export default module

export default module

---

rce – React Component class with export after

import React, { Component } from "react";

class Module extends Component {
  render() {
    return <div></div>;
  }
}

export default Module;

---

rfe or rse(deprecated) – React functional component with export after

import React from "react";

const Module = () => {
  return <div></div>;
};

export default Module;

---

rus – React useState statement

Note: this snippet takes the state placeholder and captializes the setState counterpart using snippet transforms. Just type whatever your state variable is and press "Tab" to activate the transform and move on to the next placeholder.

Note of Note: I can't get this to work with the "Vim" extension, not matter how hard I try. Sorry :(

const [state, setState] = useState();

rue – React useEffect statement

Note: I didn't place the 2nd argument of useEffect in this snippet, because I often do not know if I'm going to need it, or what props/state will go in there until I'm done writing it. It also becomes troublesome to delete the placeholder if you don't want it

useEffect(() => {});

rfeus or rfes – React functional component with export after and useState setup

Note: this snippet takes the state placeholder and captializes the setState counterpart using snippet transforms. Just type whatever your state variable is and press "Tab" to activate the transform and move on to the next placeholder.

Note of Note: I can't get this to work with the "Vim" extension, not matter how hard I try. Sorry :(

import React, { useState } from "react";

const Module = () => {
  const [state, setState] = useState();

  return <div></div>;
};

export default Module;

---

rfc – React functional component

const Module = () => {
  return <div></div>;
};

---

rfpe – React functional component with PropTypes and export after

import React from "react";
import PropTypes from "prop-types";

const Module = () => {
  return <div></div>;
};

Module.propTypes = {};

export default Module;

pt – PropTypes object

Useful if you have already created a component and decide you need Proptypes after. Uses the filename as the default for Module. Note:: VSCode snippets do not autocomplete during placeholders, so you'll want to hit escape after tabbing inside of the object

Module.propTypes = {};

---

cdu – React: componentDidUpdate

componentDidUpdate(prevProps, prevState) {

}

---

cdm – React: componentDidMount

componentDidMount() {

}

---

cdml – React: componentDidMount with log

componentDidMount() {
  console.log('Module Mounted')
}

---

cdmlc – React: componentDidMount with log (color)

componentDidMount() {
  console.log('%cModule Mounted', 'color: cornflowerblue;')
}
