wasm-flate

🗜️⚡WebAssembly power compression and decompression in the browser and server. Supports GZIP, ZLIB and DEFLATE

Project maintained by drbh

Example Node use

var flate = require('wasm-flate');

var data = "THIS IS EXAMPLE DATA TO COMPRESS"
var compressed_data = flate.zlib_encode(data)
var original_data = flate.zlib_decode(compressed_data)

Full Use Example

This will read in the string as a u8array, compress, decompress and compare the output with the original value. This show cases all the main uses of wasm-flate

var flate = require('wasm-flate');
var data = new Uint8Array( Buffer.from('wasm-flate is awesome!') );
var comp = flate.deflate_encode_raw(data)
var decomp = flate.deflate_decode_raw(comp)
JSON.stringify(data) === JSON.stringify(decomp) 

Compressing Data

Here we can see how to compress data as a string, and it will return a base64 encoded compressed value.

var data = "THIS IS EXAMPLE DATA TO COMPRESS"
var compressed_data = flate.zlib_encode(data)
// this data is zlib compressed and base64 encoded

var data = "THIS IS EXAMPLE DATA TO COMPRESS"
var compressed_data = flate.gzip_encode(data)
// this data is gzip compressed and base64 encoded

var data = "THIS IS EXAMPLE DATA TO COMPRESS"
var compressed_data = flate.deflate_encode(data)
// this data is deflate compressed and base64 encoded

Decompressing Data

var original_data = flate.zlib_decode("eNrtlEtOAzEMhvc9RTXrLpw4jmMu0EMgFk7GQQjRSjCgSlXvThgG1KpqeUgskOpN/Ppt61tkO5vPu14H7a7m2+a3aHjU3p5afD3G8yk/1vRh/bwalja0cuco+kARE/lucdRz92JjEzgiiZEAE0y23337Pgs2xbhCzOo5o5GnUvpamrSYSotbrooztQPxtAQ2Kk6sFvbcjvK+AHt1JMFqnzU5TqoYoU/76mF9b6vlx36DzOK5BK0eOVLJ5NAFBQPyTiUGqmBejyd8HgHftG6asFt8QVgkCgglCKcBMzI7hCRB4t/xdQYphkwxclOElBO7LD2IQ8SqVjBgqLH+N77nuPoLzx/zxOTPMqWAGC5cf/sP4Gm2Cbj9ANzYBrzwPeQ7vjezN2/3Cpfxnx4=")

The folowing output is some compressed JSON of ECR20 tokens traded on a DEX (the data used is arbitrary!)
