JS Tuning

Inspect your code to track its performance

Are you looking for a tool to track your code performance?

This is the project made for you!

With only 2 line, you can track all main issuer like db or http queries.

How

In first, you should create your handler. The handler is a function that will be invoked when a metric is calculated. For instance we'll use console.log function.

var myhandler = console.log.bind(null, 'Metric:');

You can send this metric to somewhere, where you prefer.

Please note: in the following example, we use the packages of the app beacuse this tool wrap all methods we need.

Mongodb

var mongodb = require('mongodb');

// pass same instance you use
require('jstuning').mongodb(mongodb, myhandler);

Mongoose

var mongoose = require('mongoose');

// pass same instance you use
require('jstuning').mongoose(mongoose, myhandler);

So difficult, right?

Why?

In my experience, nodejs is a great language. My idea starts from a real problem: how my code performs? So I haven't found a tool that permits me to track all elapsed time. This tool aimed to give you a canche to give all elapsed time and send them to some tool like Gathering or StatsD.

This project is free and has a very low integration cost. So, why not?

TODO

I've started but there're lot of things do to. I'd like to integrate major packages.

• async
• underscore / lodash
• ~~Mongodb native driver~~
• Mongoose (partially)
• request
• connect / expressjs middelware
• sequelizejs
• ...

So all your contributes are accepted and welcomed!

I'm started from packages I'm used to.
