Pako is a fast JavaScript port of the zlib compression library, providing deflate, inflate, and gzip compression with binary-equivalent output to native zlib. It works in both browsers and Node.js with a small bundle size and streaming chunked API.
Use cases
- compress data in the browser with gzip/deflate
- decompress gzip responses in JavaScript
- compress data in Node.js without native modules
- produce zlib-identical deflate output in JavaScript
- stream-compress large data chunk by chunk
- compress stringified JSON before sending to a server
When to choose
- you need zlib-compatible compression in the browser
- you want to avoid native dependencies in Node.js
- bundle size matters and you need a tiny compression library
- you need byte-identical output to native zlib
When to avoid
- you are in Node.js and native zlib performance is sufficient
- you need compression algorithms other than deflate/gzip
- maximum compression/decompression throughput is critical
