feat(next-server): implement brotli compression #19151

nicksrandall · 2020-11-13T17:10:04Z

This is is a follow up to #17766. I'm new this repo so I need some help on figuring out how to run the tests and make sure that everything is working. Any guidance on how I should proceed would be very helpful.

Background

TL;DR

Next.js uses expressjs/compression to handle gzip compression for its HTTP server.

There has been several attempts (172, 173, 158) to add brotli compression support to that library and so far none have been successfully merged (for various reasons). One of the largest reasons why this has been a challenge is because that library requires that any code is supported all the way down to Node 0.8. Also, it uses the accepts npm package which (although it is spec compliant) does not generally do what users actually want with regard to how it determines which compression encoding to use.

I have re-written the expressjs/compression library in typescript and swapped out the accetps library for @hapi/accepts which handles this issue in a more preferred way. I've also extended the library to add support for brotli compression (all of this has been added to the next-server codebase.

What is the problem that is trying to be solved?

The brotli compression algorithm is generally more efficient than gzip and now supported in recent versions of Node.js and in all major browsers. Http clients (like web browsers) can specify an "Accept-Encoding" header in their requests to share which compression algorithms they support and prefer. According to the spec, when two values have the same preference, the first value will be used (seems reasonable right?).

However, many browsers (including Google Chrome) send the "br" (brotli) value last even though it is generally preferred to the other algorithms (ie they send gzip, deflate, br instead of br, gzip, deflate). This causes the brotli compression algorithm to be de-prioritized and unused.

What can we do about it?

We can follow a well-established convention to deviate from the spec slightly and force the server to choose the "preferred" compression algorithm when the client has (basically) stated that it doesn't not explicitly prefer one algorithm over another.

So, for example, if we get an "Accept-Encoding" header value of gzip, deflate, br we will use br (brotli) because brotli is more efficient over gzip and their preference (set by client) is both 1 (the default value).

However, if we get gzip;q=0.8, br;q=0.1 (q is level of preference from 0 to 1 where 1 is most preferred) we will use 'gzip' because the client has explicitly stated that it is more preferred than brotli.

The @hapi/accepts library has this behavior by default so I'm using that as part of my compression library.

I've tested this using several of the example repos and they all seem to work but I am unable to get the test suite to work locally. Tests are failing with some jest timers issue?:

Jest encountered an unexpected token

This usually means that you are trying to import a file which Jest cannot parse, e.g. it's not plain JavaScript.

By default, if Jest sees a Babel config, it will use that to transform your files, ignoring "node_modules".

Here's what you can do:
 • To have some of your "node_modules" files transformed, you can specify a custom "transformIgnorePatterns" in your config.
 • If you need a custom transformation specify a "transform" option in your config.
 • If you simply want to mock your non-JS modules (e.g. binary assets) you can stub them out with the "moduleNameMapper" config option.

You'll find more details and examples of these config options in the docs:
https://jestjs.io/docs/en/configuration.html
