single-byte

Transforms for single-byte encodings.

Implementation has no dependencies and is based on precomputed indexes for various encodings based on specification provided by the Web Hypertext Application Technology Working Group (WHATWG).

Installation

npm install --save single-byte

Usage example

Any environment

const { encode, decode } = require('single-byte');
 
const buffer = encode('iso-8859-2', 'zażółć gęślą jaźń');
console.log(decode('iso-8859-2', buffer));

Environment supporting Node.js stream API

const fs = require('fs');
const { Encoder } = require('single-byte/stream');
 
fs.createReadStream('file-utf8.txt')
  .pipe(new Encoder('iso-8859-2'))
  .pipe(fs.createWriteStream('file-iso-8859-2.txt'));
