    RequireJS

    RequireJS

    RequireJS

    RequireJS is a JavaScript file and module loader. It is optimized for in-browser use, but it can be used in other JavaScript environments, like Rhino and Node. Using a modular script loader like RequireJS will improve the speed and quality of your code. This setup assumes you keep all your JavaScript files in a "scripts" directory in your project. To take full advantage of the optimization tool, it is suggested that you keep all inline script out of the HTML, and only reference require.js with a requirejs call like so to load your script. All of them map to loading some/path/some/module.js. Ideally we could choose the CommonJS syntax, since it is likely to get more common over time, and we want to reuse code.

    Backbone.js

    Backbone.js

    Backbone.js

    Backbone.js gives structure to web applications by providing models with key-value binding and custom events, collections with a rich API of enumerable functions, views with declarative event handling, and connects it all to your existing API over a RESTful JSON interface. When working on a web application that involves a lot of JavaScript, one of the first things you learn is to stop tying your data to the DOM. It's all too easy to create JavaScript applications that end up as tangled piles of jQuery selectors and callbacks, all trying frantically to keep data in sync between the HTML UI, your JavaScript logic, and the database on your server. For rich client-side applications, a more structured approach is often helpful. With Backbone, you represent your data as Models, which can be created, validated, destroyed, and saved to the server.

    Preact provides the thinnest possible Virtual DOM abstraction on top of the DOM. It builds on stable platform features, registers real event handlers and plays nicely with other libraries. Most UI frameworks are large enough to be the majority of an app's JavaScript size. Preact is different: it's small enough that your code is the largest part of your application. That means less JavaScript to download, parse and execute - leaving more time for your code, so you can build an experience you define without fighting to keep a framework under control. Preact is fast, and not just because of its size. It's one of the fastest Virtual DOM libraries out there, thanks to a simple and predictable diff implementation. We automatically batch updates and tune Preact to the extreme when it comes to performance. We work closely with browser engineers to get the maximum performance possible out of Preact.

    Masonry is a JavaScript grid layout library. It works by placing elements in optimal position based on available vertical space, sort of like a mason fitting stones in a wall. You’ve probably seen it in use all over the Internet. All sizing and styling of items is handled by your own CSS. Item sizes can be set with percentages for responsive layouts. Unloaded images can throw off Masonry layouts and cause item elements to overlap. imagesLoaded resolves this issue. imagesLoaded is a separate script you can download. You can initialize Masonry in HTML, without writing any JavaScript. All options are optional, but column width and item selection are recommended. Align items to a horizontal grid. Use element sizing for responsive layouts with percentage widths. Element sizing options allow you to control the sizing of the Masonry layout within your CSS. This is useful for responsive layouts and media queries.

    Trunao

    Trunao allows you to easily level up your spreadsheets into an integrated online database. With Trunao you can publish all excel worksheets online, securely share and collaborate with multiple users in an integrated online spreadsheet database in a no-code web-based application. Migrating to a cloud database is the answer to your spreadsheet data storage needs. Trunao allows you to gain access to all forms, easily collect client info, and collaborate with your team in an easy-to-use intuitive platform. While Excel spreadsheets make files much smaller and easier to work with as far as performance is concerned, analysing data across multiple excel files is far too cumbersome. Moreover, secure collaboration is nearly impossible. It’s quite tempting to use excel as a database in this era of teleworking and cloud computing, but the process can expose your business to serious risks, from data leaks to unauthorized access and reduced productivity.

    Velocity.js

    Velocity.js

    Velocity.js

    Velocity is an animation engine with the same API as jQuery's animate. It works with and without jQuery. It's incredibly fast, and it features color animation, transforms, loops, easings, SVG support, and scrolling. It is the best of jQuery and CSS transitions combined. Download Velocity, include it on your page and replace all instances of jQuery's animate with velocity. You will immediately see a performance boost across all browsers and devices, especially on mobile. Velocity works everywhere, back to IE8 and Android 2.3. Under the hood, it mimics jQuery's queue, and thus interoperates seamlessly with jQuery's animate, fade, and delay. Since Velocity's syntax is identical to animate, your code doesn't need to change. JavaScript and jQuery are falsely conflated. JavaScript animation, which Velocity uses, is fast; it's jQuery that's slow. Although Velocity works alongside jQuery, it uses its own animation stack that delivers its performance.
