binar
Encode / decode binary data using Buffer written in TypeScript
Get Started
npm install -D binar
or
yarn add -D binar
import { DataType, decodeBinar, encodeBinar } from 'binar'; test('binar', () => { const data = [ [DataType.Null, null], [DataType.Boolean, false], [DataType.Boolean, true], [DataType.Number, 0], [DataType.Number, 1], [DataType.Number, -1], [DataType.Number, Math.random()], [DataType.String, 'this is string 하하'], [DataType.Buffer, Buffer.from('another 하하')], [DataType.BigInt64BE, BigInt(-Math.floor(Math.random() * 2 ** 32))], [DataType.BigInt64LE, BigInt(-Math.floor(Math.random() * 2 ** 32))], [DataType.BigUInt64BE, BigInt(Math.floor(Math.random() * 2 ** 32))], [DataType.BigUInt64LE, BigInt(Math.floor(Math.random() * 2 ** 32))], [DataType.DoubleBE, -Math.random()], [DataType.DoubleLE, -Math.random()], [DataType.FloatBE, -Math.random()], [DataType.FloatLE, -Math.random()], [DataType.Int8, -Math.floor(Math.random() * 2 ** 4)], [DataType.Int16BE, -Math.floor(Math.random() * 2 ** 8)], [DataType.Int16LE, -Math.floor(Math.random() * 2 ** 8)], [DataType.Int32BE, -Math.floor(Math.random() * 2 ** 16)], [DataType.Int32LE, -Math.floor(Math.random() * 2 ** 16)], [DataType.UInt8, Math.floor(Math.random() * 2 ** 8)], [DataType.UInt16BE, Math.floor(Math.random() * 2 ** 16)], [DataType.UInt16LE, Math.floor(Math.random() * 2 ** 16)], [DataType.UInt32BE, Math.floor(Math.random() * 2 ** 32)], [DataType.UInt32LE, Math.floor(Math.random() * 2 ** 32)], ]; const buf = encodeBinar(data as any); console.log(Buffer.from(data.map((x) => x[1]).join(':')).toString('base64')); console.log(buf.toString('base64')); const values = decodeBinar(buf); for (let i = 0, len = values.length; i < len; i += 1) { const val = values[i]; if (typeof val === 'number') { expect(values[i]).toBeCloseTo(data[i][1] as any); } else { expect(values[i]).toEqual(data[i][1] as any); } }});
