llibencoding (Luke's Encoding Library)

Introduction

Luke's encoding library contains many stream implementations for specific types of encoding, most libraries these days only have one type of encoding, or don't use streams so I decided to create one myself because I need it for some of my projects.

Supported formats

1. Line (Wraps the data into lines, used by other formats)
2. Base64
3. Hex
4. QuotedPrintable
5. Dot Escaping (SMTP/POP3)

Usage Example

The following example usage is the same for all other encoders / decoders.

import {Readable} from 'stream';
import {Base64EncoderStream} from "llibencoding/dist/Base64EncoderStream";
import {Base64DecoderStream} from "llibencoding/dist/Base64DecoderStream";

const message: string = 'Hello World! A simple multi-line message, with quite some data so it will wrap for sure!';

const encoder: Base64EncoderStream = new Base64EncoderStream();
const decoder: Base64DecoderStream = new Base64DecoderStream();

let encoded: string = '';
let decoded: string = '';

encoder.on('data', (chunk: Buffer): void => {
  encoded += chunk.toString('utf-8');
});

decoder.on('data', (chunk: Buffer): void => {
  decoded += chunk.toString('utf-8');
});

encoder.pipe(decoder); // Decodes everything that get's encoded.

const readable: Readable = Readable.from(Buffer.from(message, 'utf-8'));
readable.pipe(encoder);
