Protoflex

Protoflex is a modern JavaScript library for working with arbitrary Protobuf data.

Online REPL: here

Why?

There were 2 main reasons for creating Protoflex:

• Debugging/reversing Protobuf HTTP(s) APIs
• Using Protobuf in relatively small scripts

So, Protoflex does its best to fit them both.

WARNING: this library is not recommended for production apps

Quick start:

Reading (deserializing)

const PB = require('protoflex')
const data = require('protoflex/utils').fromHex('082a')
console.log(PB.parse(data).int32(1))  // 42

or via JSON API:

const PB = require('protoflex')
const data = require('protoflex/utils').fromHex('082a')
console.log(PB.parse(data).toJSON()) // { '1': '42' }

Writing (serializing)

const PB = require('protoflex')
let msg = PB
    .create()
    .int32(1, 42)
console.log(msg.serialize())  // [0x08, 0x2a]

or via JSON API:

const PB = require('protoflex')
let msg = PB.fromJson({
    1: 42
})
console.log(msg.serialize())  // [0x08, 0x2a]
