Open Source JavaScript Performance Testing Software for Linux

Headless Chromium-based modular web performance metrics collector. Modular approach, each metric is generated by a separate "module". phantomas "core" acts as an events emitter that each module can hook into. In-depth metrics such as: number of events bound via jQuery, calls to window.writeor complex and duplicated CSS selectors (via analyze-css). JSON as an output format. Easy integration with other nodejs projects via CommonJS module (see API docs). Metrics can be emitted from the JavaScript code of the page phantomas is run against (thanks to helper functions available in window.__phantomas). Device profiles allow phantomas to emulate mobile or tablet (by setting a proper user agent and viewport). phantomas comes as a CommonJS module that you can use in your nodejs projects. Use grunt to automate daily dev tasks, including your's application web performance.

A simple CLI tool for ensuring that a given script runs continuously (i.e. forever). Note that this project currently fully depends on the community for implementing fixes and new features. For new installations we encourage you to use pm2 or nodemon. If you are using forever programmatically you should install forever-monitor. There are two ways to use forever: through the command line or by using forever in your code. Note: If you are using forever programatically you should install forever-monitor. You can use forever to run scripts continuously (whether it is written in node.js or not). In addition to passing forever the path to a script (along with accompanying options, described above), you may also pass forever the path to a JSON file containing these options. The forever module exposes some useful methods to use in your code. Each method returns an instance of an EventEmitter which emits when complete.
