react-zlib-js

Node's zlib core module reimplemented in JavaScript: Gzip, Deflate, Inflate, Brotli.

The same constraint as zstd-js, one layer down. A lot of libraries assume `require("zlib")` resolves to something; under React Native it does not.

This is a drop-in implementation of that surface, so code written against the Node API keeps working on platforms that have no Node.
