How to use

Encode

const { encode } = require('lossless-text-compression');

console.log(
    encode('1121231234123451234561234567123456781234567891234567890')
);

Decode

const { decode } = require('lossless-text-compression');

console.log(
    decode('11234567890')
);

With files

const { encode, decode } = require('./ltc.js');
const { readFileSync, writeFileSync } = require('fs');
  
const fileName = ...;           // for example: loremipsum.txt
const compressedFile = ...;     // for example: encoded.txt
const restoredFile = ...;       // for example: decoded.txt

// read yourfile file
const content = readFileSync(fileName, 'utf-8');

// encode and save the content
writeFileSync(compressedFile, encode(content), 'ucs2');

// read and decode the encoded content
const decoded = decode(readFileSync(compressedFileName, 'ucs2'));

// save the restored content
writeFileSync(restoredFileName, decoded, 'utf-8');
