This is yet another, and hopefully a temporary fork of https://github.com/expressjs/compression
Brotli has been enabled by default, and the compression level defaulted to 4 which is a lot more sensible/faster than Node's default. https://blogs.akamai.com/2016/02/understanding-brotlis-potential.html
Support for ancient Node versions has been dropped.
Some outstanding PRs from express have also been merged.
