React shallow render lifecycle breakdown

React introduced shallow rendering in 0.13. This is an excellent feature that I wish was included earlier in React. It aims to solve the problem of unit testing components without going through a real, or jsdom mocked, DOM. I couldn't find any info online about what lifecycle events it actually fires. So I did some testing of my own. To reproduce, put component.js and test.js into a folder and run node test.js.

TLDR; shallow rendering only invokes the following lifecycle hooks (in order):

  1. getDefaultProps
  2. getInitialState
  3. componentWillMount stops here until re-render
  4. componentWillReceiveProps
  5. shouldComponentUpdate
  6. componentWillUpdate

A little node server that logs the most recent request and response headers
const express = require('express')
const app = express()
const util = require('util')
app.get('*', function (req, res) {
process.stdout.write('\033c')
console.log('Request headers:')
console.log(util.inspect(req.headers, { colors: true }))
res.send('test')
