import { pack } from 'erlpackjs'; const packed = pack({ a: true, list: ['of', 3, 'things', 'to', 'pack'] }); console.log(packed);

Note: Unpacking requires the binary data be a Uint8Array or Buffer.

import { unpack } from 'erlpackjs'; const packed = Buffer.from('', 'binary'); let unpacked = null; try { unpacked = unpack(packed); console.log(unpacked); } catch (err) { // Got an exception parsing console.log(err); }
