A library to simplify parsing and building binary data.
It does not support all types of data, but it does have the ones I needed. :^)
A full example of how to use this library can be found in my RE MSG library.
Here are some non-exhaustive examples:
import { Decoder } from "binary-util" const data = Buffer.from([ 0x48, 0x65, 0x6c, 0x6c, 0x6f, 0x2c, 0x20, 0x57, 0x6f, 0x72, 0x6c, 0x64, 0x21, ]) const decoder = new Decoder(data) // You can use it to just read data straight from the buffer decoder.readString({ length: 5 }) // Hello decoder.readString({ length: 7 }) // ", World" // Utilities encoder.seek(-1) encoder.seek(1) encoder.alignTo(8) // Or you can use it more ergonomically when possible const decoder2 = new Decoder(Buffer.alloc(2, 2)) const result = { a: decoder2.readUint8(), // 2 b: decoder2.readUint8(), // 2 }
import { Encoder } from "binary-util" const encoder = new Encoder() encoder.writeString("Hello, World") encoder.seek(-1) encoder.seek(1) encoder.alignTo(8) encoder.writeUint8(2) encoder.goto(1)
