zzetf

A zig Implementation of the Erlang Term Format providing ZSTD streaming decompression for Discord WebSockets.

This doesnt use node-gyp or any other dependencies, it comes prebuilt for most platforms.

Usage

const { etfDecode, etfEncode, zstdEtfStreamDecoder } = require("zzetf");

const data = etfEncode("Hello, World!"); // <Buffer 83 6d 00 00 00 0d ... 21>
const decoded = etfDecode(data); // "Hello, World!"

const streamingDecoder = zstdEtfStreamDecoder();

// feed data from discords websocket
const out = streamingDecoder.decode(somedata);

// deinitialize the streaming decoder when you're done
streamingDecoder.deinit();

Bigints

Discord encodes snowflakes as bigints, however most libraries require snowflakes to be strings.

Hence we provide a compatibility option:

import { etfDecode, etfEncode } from "zzetf";

etfDecode(etfEncode(12345678901234567890n), { bigintsAsStrings: true }); // "12345678901234567890"

// or, for streaming
streamingDecoder.decode(somedata, { bigintsAsStrings: true });
