About

External Text Format is the format Erlang uses when sending and receiving data. This module implements packing and unpacking of said format in pure, native JavaScript.

Usage

This module is plug-and-play, it exposes two functions, pack and unpack, and would be used in the following way:

const { pack, unpack } = require('etf.js');
const serialized = pack({ hello: 'world' });
const deserialized = unpack(serialized);
console.log(deserialized); // { hello: 'world' }

What can be packed

• Null (Primitive Tests)
• Booleans (Primitive Tests)
• Strings (Primitive Tests)
• Atoms (Atom Tests)
• Unicode Strings (String Tests)
• Floats (Primitive Tests)
• Integers (Primitive Tests)
• Longs (Primitive Tests)
• Longs over 64 bits (Primitive Tests)
• Objects
• Arrays
• Tuples
• PIDs
• Ports
• Exports
• References

Plus added support for Maps (will be converted into Objects) and Sets (will be converted into Arrays)
