Configuring Emacs for react, es6, and flow

For a while, JSX and new es6 syntax had flaky support in emacs, but there's been huge work on a lot of packages. Using emacs for JavaScript with React, ES6, and Flow (or Typescript, etc) is really easy and powerful in Emacs these days.

This is how you can work on modern web development projects with full support for tooling like JSX, Flow types, live eslint errors, automatic prettier.js formatting, and more.

Set up web-mode

web-mode provides most of the underlying functionality, so a huge shout-out to the maintainer(s) there.

#!/bin/bash

# Create lxc profile with apt caching
# Requires installing apt-cacher-ng to 10.0.4.1 (your host)
# Could be improved by making the actual apt cache host tunable
# Then use like:
# lxc launch -p default -p aptcache ubuntu:16.04 my-cached-container
NAME=aptcache
CACHE_IP=$(ip addr list lxdbr0 | grep -Po 'inet \K[\d.]+')
if ! ping -c 1 "$CACHE_IP" -w 1 >/dev/null 2>&1; then

How to add an image to a gist

1. Create a gist if you haven't already.
2. Clone your gist:

   # make sure to replace `<hash>` with your gist's hash
   git clone https://gist.github.com/<hash>.git # with https
   git clone git@gist.github.com:<hash>.git     # or with ssh

# Ubuntu Server or VM Cleaner. Safe by default; aggressive when asked.
# Example safe:       sudo ./clean.sh
# Example aggressive: sudo JOURNAL_DAYS=3 AGGRESSIVE=1 ./clean.sh
# Enable Docker image prune (images only): sudo ./clean.sh --docker-images
# Tested on Ubuntu 20.04, 22.04, 24.04 (server/VM images).
