    jeelizFaceFilter

    jeelizFaceFilter

    Javascript/WebGL lightweight face tracking library

    This JavaScript library detects and tracks the face in real time from the camera video feed captured with WebRTC. Then it is possible to overlay 3D content for augmented reality applications. We provide various demonstrations using main WebGL 3D engines. We have included in this repository the release versions of the 3D engines to work with a determined version (they are in /libs/<name of the engine>/). This library is lightweight and it does not include any 3D engine or third-party library. We want to keep it framework agnostic so the outputs of the library are raw, if the face is detected or not, the position and the scale of the detected face and the rotation Euler angles. But thanks to the featured helpers, examples and boilerplates, you can quickly deal with a higher level context (for motion head tracking, for face filter or face replacement). We continuously add new demonstrations, so stay tuned!

    jscodeshift

    jscodeshift

    A JavaScript codemod toolkit

    jscodeshift is a toolkit for running codemods over multiple JavaScript or TypeScript files. It provides A runner, which executes the provided transform for each file passed to it. It also outputs a summary of how many files have (not) been transformed. A wrapper around recast, providing a different API. Recast is an AST-to-AST transform tool and also tries to preserve the style of original code as much as possible. As already mentioned, jscodeshift also provides a wrapper around recast. In order to properly use the jscodeshift API, one has to understand the basic building blocks of recast (and ASTs) as well. An AST node is a plain JavaScript object with a specific set of fields, in accordance with the Mozilla Parser API. The primary way to identify nodes is via their type. It's OK to not know the structure of every AST node type. The (esprima) AST explorer is an online tool to inspect the AST for a given piece of JS code.

    json-forms

    json-forms

    JSON Schema to HTML form generator, supporting dynamic subschemas

    JSON Schema to HTML form generator, supporting dynamic subschemas (on-the-fly resolution). Extensible and customizable library with zero dependencies. Bootstrap add-ons provided. This library supports dynamic schemas, that is, subschemas that can change depending on the value of other parts of the data. This allows the creation of dynamic forms that vary their shape depending on the values entered by the user. This is extremely useful for big autogenerated schemas, that aggregate lots of subschemas and have functional bindings, given that it allows to show the user a simpler, non-error-prone form, also avoiding asking for unneeded data.

    keymaster.js

    keymaster.js

    A simple micro-library for defining and dispatching keyboard shortcuts

    Keymaster is a simple micro-library for defining and dispatching keyboard shortcuts in web applications. It has no dependencies. It’s a work in progress (e.g. beta), so spare me your nerdrage and instead contribute! Patches are welcome, but they are not guaranteed to make it in. Include keymaster.js in your web app*, by loading it as usual. Keymaster has no dependencies and can be used completely standalone. It should not interfere with any JavaScript libraries or frameworks. *Preferably use a minified version that fits your workflow. You can run make to have UglifyJS (if you have it installed) create a keymaster.min.js file for you. At any point in time (even in code other than key shortcut handlers), you can query the key object for the state of any keys. This allows easy implementation of things like shift+click handlers. For example, key.shift is true if the shift key is currently pressed.

    lax.js

    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.
