firmata.js typings

[troywweber7]

Hello! I am interested in finding a definition file for firmata.js (or in helping to generate one). The way I'm giving myself typescript support for firmata.js right now is INCREDIBLY HACKY. In fact, I know its the wrong way and I know all it is doing is keeping the compiler from complaining and helping provide me with some auto-completion. So I would really like some help in figuring out the right way to do this. Eventually I'd like to include a typings file in DefinitelyTyped so I can use $ typings search firmata and $ typings install --save --global dt~firmata.

What I have so far I use with

import { IBoard } from './interfaces/Firmata';

And the file Firmata.d.ts has this for its contents

// TODO this can definitely be done better with a better understanding of prototypal inheritance

import SerialPort = require("serialport");

As you can see, there are incomplete functions and I'm probably doing this the worst way possible, so any help is greatly appreciated.

firmata.js is here, btw: https://github.com/firmata/firmata.js

Thanks. I'm not sure anyone will jump in directly to help you unless they're using it. If you have something that works, perhaps the best approach is to create a repo and add it to the registry and hope someone else finds it useful also to contribute?
