    Bootstrap Colorpicker

    Bootstrap Colorpicker

    Bootstrap Colorpicker is a modular color picker plugin for Bootstrap

    Bootstrap Colorpicker is a modular color picker plugin for Bootstrap 4. The Bootstrap JS dependency is optional and it is mainly needed for the popover support. No Bootstrap CSS is required for the plugin to work. To use the plugin without Bootstrap, the popover option should be set to false or null and, depending on your implementation, you will usually need to set inline to true and a container selector option. Note that the plugin may work without Bootstrap if your code is not using any of the mentioned Bootstrap dependencies. Note that the dist files are only distributed via the NPM and Yarn installations. The initial color can be specified in 3 ways, input value, data-color attribute and programmatically with the color constructor option. Whenever the format option is 'auto', the first parsed color format will be detected and used as default, but when the option equals null (default), the format is recalculated every time.

    Bootstrap Modal

    Bootstrap Modal

    Extends the default Bootstrap Modal class

    Extends Bootstrap's native modals to provide additional functionality. Introduces a ModalManager class that operates behind the scenes to handle multiple modals by listening on their events. A single ModalManager is created by default on body and can be accessed through the jQuery plugin interface. Bootstrap-Modal can be used as a replacement for Bootstrap's Modal class or as a patch to the library. If you're using the loading spinner functionality you may also need to change the default template to be compatible in js. Since this plugin was created to solve a lot of the issues with BS2, it still uses the BS2 markup syntax. You can bind the height of the modal body to the window. You can use data-tabindex instead of the default tabindex to specify the tabindex within a modal. The shake animation is included in bootstrap-modal but any animation in animate.css is supported, just include the css file in your project.

    Browserify

    Browserify

    browser-side require() the node.js way

    Browserify lets you require('modules') in the browser by bundling up all of your dependencies. Browsers don't have the require method defined, but Node.js does. With Browserify you can write code that uses require in the same way that you would use it in Node. Install the uniq module with npm. Now recursively bundle up all the required modules starting at main.js into a single file called bundle.js with the browserify command. Browserify parses the AST for require() calls to traverse the entire dependency graph of your project. Drop a single <script> tag into your html and you're done! browserify is a tool for compiling node-flavored commonjs modules for the browser. You can use browserify to organize your code and use third-party libraries even if you don't use node itself in any other capacity except for bundling and installing packages with npm.

    Cash

    Cash

    An absurdly small jQuery alternative for modern browsers

    Cash is an absurdly small jQuery alternative for modern browsers (IE11+) that provides jQuery-style syntax for manipulating the DOM. Utilizing modern browser features to minimize the codebase, developers can use the familiar chainable methods at a fraction of the file size. 100% feature parity with jQuery isn't a goal, but Cash comes helpfully close, covering most day to day use cases. Cash gives you a query selector, collection methods and some library methods. If you need more details about our API just check out jQuery's, while we don't implement everything that jQuery provides, everything what we do implement should be compatible with jQuery. Cash can be extended with custom methods. If you're migrating from jQuery be sure to read our migration guide. A 76.6% gain in size reduction compared to jQuery. If you need a smaller bundle, we support partial builds too.
