base64-async

Non-blocking chunked Base64 encoding.

base64-async helps us in processing large Base64 documents without blocking the event loop, one can configure chunk size option to optimise for your use case.

This module exposes: b64, encode and decode methods which accepts (input, [options]) and returns a promise on innvocation.

Get it: npm install --save base64-async

Sample usage:

const b64 = require('base64-async');
const fs = require('fs');
const buffer = fs.readFileSync('somehugefile.jpg');

b64.encode(fileBuffer).then(b64String => console.log(b64String));
// aGkgbXVt... 

b64.decode(b64String).then(buffer => console.log(buffer));
// <Buffer 68 69 20 6d 75 6d ... > 

// or, for the cool kids 
const b64String = await b64.encode(fileBuffer);
const originalFileBuffer = await b64.decode(b64String);

// which is equivalent to this 
const b64String = await b64(fileBuffer);
const originalFileBuffer = await b64(b64String);
// If no method is specified, buffers are encoded, strings are decoded

GIF FTW!
