amf-codec

About

Tiny AMF0 encoder/decoder with high performance.

Usage

Install using npm:

$ npm install amf-codec

Encode

const { toAMF } = require('amf-codec');

const data = {
	'foobar': 42,
};

console.log(toAMF(data));

Decode

const { fromAMF } = require('amf-codec');

const data = Buffer.from([1, 1]);

console.log(fromAMF(data));

Decode from arbitrary position

For example to skip the first byte of buffer:

const { decodeAMF, Memo } = require('amf-codec');

const data = Buffer.from([0, 1, 1]);

console.log(decodeAMF(data, new Memo(1)));

Memo class

const { Memo } = require('amf-codec');

const data = Buffer.from([0, 1, 2, 3, 4, 5, 6]);
const memo = new Memo(1); // set initial position to ignore 1 byte

console.log(data.readUInt16BE(memo.consume(2)/* === 1 */));
// consume(amount of bytes) returns current position before increasing its value
console.log(data.slice(memo.position/* === 3*/, memo.skip(4)/* === 7*/));
// skip(amount of bytes) increases position before returning its value
