How to setup a practically free CDN using Backblaze B2 and Cloudflare

⚠️ Note 2023-01-21
Some things have changed since I originally wrote this in 2016. I have updated a few minor details, and the advice is still broadly the same, but there are some new Cloudflare features you can (and should) take advantage of. In particular, pay attention to Trevor Stevens' comment here from 22 January 2022, and Matt Stenson's useful caching advice. In addition, Backblaze, with whom Cloudflare are a Bandwidth Alliance partner, have published their own guide detailing how to use Cloudflare's Web Workers to cache content from B2 private buckets. That is worth reading,

Forking a single package in a monorepo

The trend of using monorepos makes a lot of things easier to manage. However, when you want to fork a single package inside a monorepo, you'll have to chose one of two options:

Fork the entire monorepo (meaning you get all those extra boilerplate you don't really care about)
Manually copying the package files into a new git repo (meaning you'll loose all git history and have a lot of work to do when there's a new version of your base package)

The good news: There's a solution for this! And it's actually built in to git.

`git subtree`

One of the lesser-known (and vaguely documented) features of git is subtree. It's intended for this purpose, working as a great alternative to the criticized submodules. There are very few resources about using this in practice, so here's a guide for this specific use case.
