glMatrix
Javascript Matrix and Vector library for High Performance WebGL apps
Javascript has evolved into a language capable of handling realtime 3D graphics, via WebGL, and computationally intensive tasks such as physics simulations. These types of applications demand high performance vector and matrix math, which is something that Javascript doesn't provide by default. glMatrix to the rescue! glMatrix is designed to perform vector and matrix operations stupidly fast! By hand-tuning each function for maximum performance and encouraging efficient usage patterns through API conventions, glMatrix will help you get the most out of your browsers Javascript engine. -

React Native Vector Icons
Customizable Icons for React Native with full styling
Perfect for buttons, logos and nav/tab bars. Easy to extend, style and integrate into your project. If you want to use any of the bundled icons, you need to add the icon fonts to your Xcode project. For each platform (iOS/Android/Windows) you plan to use, follow one of the options for the corresponding platform. Upgrading this package often requires the font files linked to your projects to be updated as well. If the automatic linking works for you, running this again should update the fonts. You can either use one of the bundled icons supported or roll your own custom font. Since Icon builds on top of the Text component, most style properties will work as expected, you might find it useful to play around with background color, border width, border color, border radius, padding, margin, color, font size, etc. -

Jimp
An image processing library written entirely in JavaScript for Node
An image processing library for Node written entirely in JavaScript, with zero native dependencies. If you're using this library with TypeScript the method of importing slightly differs from JavaScript. Instead of using require, you must import it with ES6 default import scheme. If you're using a web bundles (webpack, rollup, parcel) you can benefit from using the module build of jimp. Using the module build will allow your bundler to understand your code better and exclude things you aren't using. If you're using webpack you can set process.browser to true and your build of jimp will exclude certain parts, making it load faster. The static Jimp.read method takes the path to a file, URL, dimensions, a Jimp instance or a buffer and returns a Promise. In some cases, you need to pass additional parameters with an image's URL. -

Typed.js
A JavaScript typing animation library
Typed.js is a library that types. Enter in any string, and watch it type at the speed you've set, backspace what it's typed, and begin a new sentence for however many strings you've set. Rather than using the strings array to insert strings, you can place an HTML div on the page and read from it. This allows bots and search engines, as well as users with JavaScript disabled, to see your text on the page. You can pause in the middle of a string for a given amount of time by including an escape character. CSS animations are built upon initialization in JavaScript. But, you can customize them at your will! -

C3.js
A D3-based reusable chart library
C3 makes it easy to generate D3-based charts by wrapping the code required to construct the entire chart. We don't need to write D3 code any more. C3 gives some classes to each element when generating, so you can define a custom style by the class and it's possible to extend the structure directly by D3. C3 provides a variety of APIs and callbacks to access the state of the chart. By using them, you can update the chart even after it's rendered. C3 enables deeper integration of charts into your application. Because of the dependence on D3, C3 supports only modern browsers D3 supports. For IE9 and IE10, polyfill is required because c3 uses MutationObserver, which is not supported in those versions. However, it's not required if charts always will be binded to the DOM specified by bindto because MutationObserver is not called in that case. -

CSSgram
CSS library for Instagram filters
Simply put, CSSgram is a library for editing your images with Instagram-like filters directly using CSS. What we're doing is adding filters to the images, as well as applying color and/or gradient overlays via various blending techniques to mimic filter effects. This means less manual image processing and more fun filter effects on the web! We are using pseudo-elements (i.e. :before and :after) to create the filter effects, so you must apply these filters on a containing element (i.e. not a content-block like <img>. The recommendation is to wrap your images in a <figure> tag. If you use custom naming in your CSS architecture, you can add the .scss files for the provided styles within your project and then @extend the filter effects within your style definitions. Mixins allow for multiple filter arguments to be passed into your classes. This is useful for if you want to add filters in addition to the ones provided (i.e. add a blur). -

Chart.xkcd
xkcd styled chart lib
Chart.xkcd is a chart library plots “sketchy”, “cartoony” or “hand-drawn” styled charts. It’s easy to get started with chart.xkcd. All that’s required is the script included in your page along with a single <svg> node to render the chart. You can install chart.xkcd via script tag in HTML or via npm. Line chart displays series of data points in the form of lines. It can be used to show trend data, or comparison of different data sets. XY chart is used to plot points by specifying their XY coordinates. A bar chart provides a way of showing data values represented as vertical bars. A stacked bar chart provides a way of showing data values represented as vertical bars. Display labels near every line (default false). Customize tick numbers you want to see on the main line. You can change size of the dots if you want. -

Chartist.js
Simple responsive charts
You may think that this is just yet an other charting library. But Chartist.js is the product of a community that was disappointed about the abilities provided by other charting libraries. Of course there are hundreds of other great charting libraries but after using them there were always tweaks you would have wished for that were not included. Are you planning to use Chartist to create a nice Dashboard or Admin UI? Don't loose any time and kickstart your development using the awesome templates by Creative Tim. They include Chartist and come with awesome chart styles! Specifying the style of your chart in CSS is not only cleaner but also enables you to use awesome CSS animations and transitions to be applied to your SVG elements! Note that CSS3 animations on SVG CSS attributes are not supported on all browsers and the appearance may vary. -

Emoji Mart
One component to pick them all
Data required for the picker to work has been completely decoupled from the library. That gives developers the flexibility to better control their app bundle size and let them choose how and when this data is loaded. Callback when the Add custom emoji button is clicked. The button will only be displayed if this callback is provided. It is displayed when search returns no results. You can use custom emojis by providing an array of categories and their emojis. Emojis also support multiple skin tones and can be GIFs or SVGs. You can use custom category icons by providing an object with the category name as key and the icon as value. Currently supported formats are svg string and src. First, you need to make sure data has been initialized. You need to call this only once per page load. Note that if you call init like this, you don’t necessarily need to include data in your Picker props. It doesn’t hurt either, it will noop. -

Emoji-Log
An Emoji Git commit log messages spec standard
After building hundreds of open source software I've ended up inventing a git commit log standard called EMOJI-LOG that helps me understand a project's history with a less cognitive load just by looking at the git log. I like emoji. I like ’em a lot. Programming, code, geeks/nerds, open-source, all of that is inherently dull and sometimes boring. Emoji (which is, in fact, the plural of emoji) helps me add colors and emotions to the mix. Nothing wrong if you want to attach feelings to this 2D flat text-based world of code. I found out that instead of memorizing hundreds of emoji it's better to keep the categories small and general. -

Raphaël
JavaScript vector library
Raphaël is a small JavaScript library that should simplify your work with vector graphics on the web. If you want to create your own specific chart or image crop and rotate widget, for example, you can achieve it simply and easily with this library. Raphaël ['ræfeɪəl] uses the SVG W3C Recommendation and VML as a base for creating graphics. This means every graphical object you create is also a DOM object, so you can attach JavaScript event handlers or modify them later. Raphaël’s goal is to provide an adapter that will make drawing vector art compatible cross-browser and easy. Raphaël currently supports Firefox 3.0+, Safari 3.0+, Chrome 5.0+, Opera 9.5+ and Internet Explorer 6.0+. Versions will be released as we gather and test new PRs. As there are a lot of browsers being supported it might take a while to accept a PR, we will use the feedback from other users too. You can use the raphaelTest.html to try things, you need to start a server in the root dir to start testing things there. -

Vivus.js
JavaScript library to make drawing animation on SVG
Vivus is a lightweight JavaScript class (with no dependencies) that allows you to animate SVGs, giving them the appearence of being drawn. There are a variety of different animations available, as well as the option to create a custom script to draw your SVG in whatever way you like. Every path element is drawn at the same time with a small delay at the start. This is currently the default animation. Each line is drawn synchronously. They all start and finish at the same time, hence the name `sync`. Each path element is drawn one after the other. This animation gives the best impression of live drawing. To give more freedom, it's possible to override the animation of each path and/or the entire SVG. It works a bit like the CSS animation timing function. But instead of using a cubic-bezier function, it use a simple JavaScript function. It must accept a number as parameter (between 0 to 1), then return a number (also between 0 and 1). It's a hook. -

embed-js
A lightweight plugin to embed emojis, media, maps, tweets, code, etc.
A lightweight JavaScript plugin to embed emojis, media, maps, tweets, code and services. embed.js was developed with a modern JavaScript workflow in mind. To use it, it's recommended you have a build system in place that can transpile ES6, and bundle modules. But at the same time, you get an already transpiled version to make your development easier. If you’re using npm package manager with a module bundler like Webpack or Browserify to consume CommonJS modules, you can use the default UMD build of the plugin by simply requiring it. The render() method renders the resulting string in the block. The .render() method also returns a promise. Optionally you can also pass a string which will be processed by the plugin. -

gitmoji
An emoji guide for your commit messages
Gitmoji is an initiative to standardize and explain the use of emojis on GitHub commit messages. Gitmoji is an emoji guide for GitHub commit messages. Aims to be a standarization cheatsheet, guide for using emojis on GitHub's commit messages. Using emojis on commit messages provides an easy way of identifying the purpose or intention of a commit with only looking at the emojis used. As there are a lot of different emojis I found the need of creating a guide that can help to use emojis easier. This project is Open Source, that means everyone can participate, suggesting, discussing and adding new emojis. Take a look at the contributing section and guidelines for contributing. An easy solution for using gitmoji from your command line, is to install gitmoji-cli. A gitmoji interactive client for using emojis on commit messages. This project is a static website built with Next.js. All the gitmojis displayed are rendered from a JSON file. -

lax.js
Library to create smooth & beautiful animations when you scroll
Simple & lightweight (<4kb gzipped) vanilla JavaScript library to create smooth & beautiful animations when you scroll. Lax.js 2.0 has been completely re-written with a focus on modularity and flexibility giving you more tools to create awesome animations. To implement lax you need to create at least one driver, to provide values for animations, as well as the element animation bindings. The easiest way to get started is to use presets via html classes. Multiple presets can be chained together and they can be customised to suit your needs. Use the preset explorer to explore effects and see a simple example here. To increase performance, lax.js indexes the list of elements to animate when the page loads. If you're using a library like React, Vue or EmberJS, it is likely that you are adding elements after the initial window.onload. Because of this you will need to call lax.addElements when you add components to the DOM that you want to animate. -

nivo
A rich set of dataviz components
nivo provides a rich set of dataviz components, built on top of the awesome d3 and Reactjs libraries. Several libraries already exist for React d3 integration, but just a few provide server side rendering ability and fully declarative charts. In order to use nivo, you have to install the @nivo/core package and then choose some of the scoped @nivo packages according to the charts you wish to use. Given an array of data series having an id and a nested array of points (with x, y properties), it will compute the line for each data series. All datum having null x or y will be treated as holes, thus portions of the corresponding line will be skipped. You can fully customize it using the circleComponent property to define your own, if you wish to do so you should have a look at the default SVG component to get started. Bar chart which can display multiple data series, stacked or side by side. Also supports both vertical and horizontal layout, with negative values descending below the x axis.
