    Bootstrap Icons

    Bootstrap Icons

    Open source SVG icon library for Bootstrap

    Free, high-quality, open-source icon library with over 1,600 icons. Include them any way you like, SVGs, SVG sprite, or web fonts. Use them with or without Bootstrap in any project. Bootstrap Icons are published to npm, but they can also be manually downloaded if needed. Bootstrap Icons are SVGs, so you can include them into your HTML in a few ways depending on how your project is setup. We recommend using a width: 1em (and optionally height: 1em) for easy resizing via font-size. Embed your icons within the HTML of your page (as opposed to an external image file). Here we’ve used a custom width and height. Use the SVG sprite to insert any icon through the <use> element. Use the icon’s filename as the fragment identifier (e.g., toggles is #toggles). SVG sprites allow you to reference an external file similar to an <img> element, but with the power of currentColor for easy theming.

    jQuery

    jQuery

    jQuery JavaScript library

    jQuery is a fast, small, and feature-rich JavaScript library. It makes things like HTML document traversal and manipulation, event handling, animation, and Ajax much simpler with an easy-to-use API that works across a multitude of browsers. With a combination of versatility and extensibility, jQuery has changed the way that millions of people write JavaScript. jQuery also supports Node, browser extensions, and other non-browser environments. To build jQuery, you need to have the latest Node.js/npm and git 1.7 or later. Earlier versions might work, but are not supported. Special builds can be created that exclude subsets of jQuery functionality. This allows for smaller custom builds when the builder is certain that those parts of jQuery are not being used. For example, an app that only used JSONP for $.ajax() and did not need to calculate offsets or positions of elements could exclude the offset and ajax/xhr modules.

    Retire.js

    Retire.js

    Scanner detecting the use of JavaScript libraries

    There is a plethora of JavaScript libraries for use on the web and in node.js apps out there. This greatly simplifies, but we need to stay updated on security fixes. "Using Components with Known Vulnerabilities" is now a part of the OWASP Top 10 and insecure libraries can pose a huge risk for your web app. The goal of Retire.js is to help you detect the use of versions with known vulnerabilities. Scan a web app or node app for use of vulnerable JavaScript libraries and/or node modules. grunt-retire scans your grunt-enabled app for use of vulnerable JavaScript libraries and/or node modules. Scans visited sites for references to insecure libraries and puts warnings in the developer console. An icon on the address bar displays will also indicate if vulnerable libraries were loaded. Retire.js has been adapted as a plugin for the penetration testing tools Burp and OWASP ZAP.

    SuperTest

    SuperTest

    Super-agent driven library for testing node.js HTTP servers

    A super-agent driven library for testing node.js HTTP servers using a fluent API. The motivation with this module is to provide a high-level abstraction for testing HTTP, while still allowing you to drop down to the lower-level API provided by superagent. Install SuperTest as an npm module and save it to your package.json file as a development dependency. You may pass an http.Server, or a Function to request(), if the server is not already listening for connections then it is bound to an ephemeral port for you so there is no need to keep track of ports. One thing to note, is that superagent now sends any HTTP error (anything other than a 2XX response code) to the callback as the first argument if you do not add a status code expect (i.e. .expect(302)). Expectations are run in the order of definition. This characteristic can be used to modify the response body or headers before executing an assertion.

    Modernizr

    Modernizr

    JS library that detects HTML5 & CSS3 features in user’s browser

    Modernizr is a JavaScript library that tells you what HTML, CSS and JavaScript features are present in your user’s browser. This helps you to respond better to your users’ browser features and offer a more tailored experience. Differences in users’ browsers and devices can often cause differences in user experience when opening your web page. To provide a consistently great user experience, you need to be able to respond to your users’ browser features in the best way. Modernizr detects the specific feature sets in each browser so you can easily deliver a tiered experience to users: using the latest features available for modern browsers while still supporting older ones.

    Twemoji

    Twemoji

    Simple library that provides standard Unicode emoji for all platforms

    Twitter’s open source emoji has you covered for all your project's emoji needs. With support for the latest Unicode emoji specification, featuring 3,245 emojis, and all for free. As an open source project, attribution is critical from a legal, practical and motivational perspective in our opinion. The graphics are licensed under the CC-BY 4.0 which has a pretty good guide on best practices for attribution. Although there are two kinds of parsing supported by this utility, we recommend you use DOM parsing, explained below. Each type of parsing accepts a callback to generate an image source or an options object with parsing info. The second kind of parsing is string parsing. This is unrecommended because this method does not sanitize the string or otherwise prevent malicious code from being executed; such sanitization is out of scope.

    TensorFlow

    TensorFlow

    TensorFlow is an open source library for machine learning

    Originally developed by Google for internal use, TensorFlow is an open source platform for machine learning. Available across all common operating systems (desktop, server and mobile), TensorFlow provides stable APIs for Python and C as well as APIs that are not guaranteed to be backwards compatible or are 3rd party for a variety of other languages. The platform can be easily deployed on multiple CPUs, GPUs and Google's proprietary chip, the tensor processing unit (TPU). TensorFlow expresses its computations as dataflow graphs, with each node in the graph representing an operation. Nodes take tensors—multidimensional arrays—as input and produce tensors as output. The framework allows for these algorithms to be run in C++ for better performance, while the multiple levels of APIs let the user determine how high or low they wish the level of abstraction to be in the models produced. Tensorflow can also be used for research and production with TensorFlow Extended.

To be precise, it is more for back-end developers. You don’t need to get involved in various front-end tools. You only need to face the browser itself, and let all the elements and interactions you need come from here at your fingertips.
