Don't use VPN services.

No, seriously, don't. You're probably reading this because you've asked what VPN service to use, and this is the answer.

Note: The content in this post does not apply to using VPN for their intended purpose; that is, as a virtual private (internal) network. It only applies to using it as a glorified proxy, which is what every third-party "VPN provider" does.

• There's also this article about VPN services, which is honestly better written (and has more cat pictures!) than my article.

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.

EMACS JS DEBUGGING WITH INDIUM

1. indium requires a config file to be setup .indium.json
2. M-x indium-launch

The .indium.json file can contain as many configurations as needed, and mix any supported configuration types.

The currently supported type values are "chrome" and "node".

The root directory of the source files is by default set to the directory where this .indium.json file is placed, but it can be overridden with the root (or the webRoot alias) option:
