React component templates and style guide

NOTE: This should be an ever changing document that is kept up to the date with the teams standard.

Class components

Things to note

• import order is important. No spaces should be added in between import statement. It is not needed as an identifier between different "imports types". The order is as follows:

1. Libraries (react, prop-types, lodash, etc.)

Install command line tools:

then run this:

git config --global diff.tool bc3
git config --global difftool.bc3 trustExitCode true
git config --global merge.tool bc3

So you've cloned somebody's repo from github, but now you want to fork it and contribute back. Never fear!

Technically, when you fork "origin" should be your fork and "upstream" should be the project you forked; however, if you're willing to break this convention then it's easy.

* Off the top of my head *

1. Fork their repo on Github
2. In your local, add a new remote to your fork; then fetch it, and push your changes up to it

    git remote add my-fork git@github...my-fork.git

// Separate the container and presentional components

import React, { Component } from 'react'

// Presentational component is pure. It is only responsible for accepting props and returning JSX.
const Child = ({ show, onClickShow, onClickHide }) => (
  <div>
  {show && <span>Now you can see me!</span>}
    <button onClick={onClickShow}>Show</button>
    <button onClick={onClickHide}>Hide</button>
