    Traceur

    Traceur

    Traceur is a JavaScript.next-to-JavaScript-of-today compiler

    Traceur is a JavaScript.next-to-JavaScript-of-today compiler that allows you to use features from the future today. Traceur supports ES6 as well as some experimental ES.next features. Traceur's goal is to inform the design of new JavaScript features which are only valuable if they allow you to write better code. Traceur allows you to try out new and proposed language features today, helping you say what you mean in your code while informing the standards process. JavaScript's evolution needs your input. Try out the new language features. Tell us how they work for you and what's still causing you to use more boilerplate and "design patterns" than you prefer. You can use some language features right now and even try it out in your browser here. Just type in some code and see what Traceur produces.

    URI.js

    URI.js

    Javascript URL mutation library

    URI.js is a javascript library for working with URLs. It offers a "jQuery-style" API (Fluent Interface, Method Chaining) to read and write all regular components and a number of convenience methods like .directory() and .authority(). URI.js offers simple, yet powerful ways of working with query string, has a number of URI-normalization functions and converts relative/absolute paths. While URI.js provides a jQuery plugin. URI.js itself does not rely on jQuery. You don't need jQuery to use URI.js. URI.js (without plugins) has a gzipped weight of about 7KB, if you include all extensions you end up at about 13KB. So unless you need second level domain support and use URI templates, we suggest you don't include them in your build. Clone the URI.js repository or use a package manager to get URI.js into your project. See the build tool or use Google Closure Compiler.

    Vimperator-labs
    Writing efficient user interfaces is the main maxim, here at Vimperator labs. We often follow the Vim way of doing things, but extend its principles when necessary. Towards this end, we’ve created the liberator library for Mozilla-based applications, to encapsulate as many of these general principles as possible, and liberate developers from the tedium of reinventing the wheel.´Vimperator is a Firefox browser extension with strong inspiration from the Vim text editor, with a mind towards faster and more efficient browsing. It has similar key bindings and you could call it a modal web browser, as key bindings differ according to which mode you are in. For example, it has a special Hint mode, where you can follow links easily with the keyboard only. Also most functionality is available as commands, typing:back will go back within the current page history, just like hitting the back button in the toolbar.

    Visibility.js

    Visibility.js

    Wrapper for the Page Visibility API

    Visibility.js is a small JavaScript library that wraps the native Page Visibility API to give developers an easy interface for detecting when a user’s browser tab becomes visible, hidden, or is in prerendering mode. Its main purpose is to let web applications adapt behavior depending on whether the page is actually being viewed — for example, pausing animations, postponing heavy computations, or stopping unnecessary network requests when the user switches to another tab. The library hides browser vendor-prefixes and normalizes visibility events so you don’t have to manage cross-browser quirks yourself. On top of simple visibility detection, Visibility.js adds useful helpers such as a timer function that only runs when the page is visible. As a result, developers can write resource-conscious web apps that reduce CPU/bandwidth usage when the user isn’t actively viewing the page.

    Vue module for lazyloading images in your applications.

It supports both of Vue 1.0 and Vue 2.0. You can configure which events you want vue-lazyload by passing in an array of listener names. This is useful if you are having trouble with this plugin resetting itself to loading when you have certain animations and transitions taking place. use Intersection Observer to to improve performance of a large number of nodes. If only the event is provided, remove all listeners for that event. Manually trigger lazy loading position calculation.
