cxjs - CxJS - Advanced JavaScript UI framework for admin and dashboard applications with ready to use grid, form and chart components

Javascript

CxJS, or simply Cx, is a feature-rich JavaScript framework for building complex web front-ends, such as BI tools, dashboards and admin apps. Modern frameworks such as React and Angular provide an excellent base for building UI components, however, component implementation and many other application aspects are left to the developer to figure out. CxJS tries to fill that gap and provide the all necessary ingredients required for modern web applications. CxJS Hacker News is a Progressive Web App focused on startup performance. The application is based on Preact and uses webpack plugins to enable preloading, inline CSS and JS, configure service workers and achieve other performance gains.

regula - Regula: An annotation-based form-validation framework in Javascript

Javascript

Regula is small. It's around 220Kb un-compressed, and 64Kb minified. Regula also doesn't depend on any other external libraries, so you don't have any other dependencies. Not that different, right? Now how about other frameworks? While also useful, binding constraints to elements in other frameworks is somewhat verbose because all constraint-binding is done in Javascript. This has two problems: verbosity (as I mentioned earlier), and lack of context. Part of the appeal of HTML5 constraint validation is that one can immediately tell what restrictions apply to an input field simply by looking at the code. When using other validation-frameworks which rely solely on Javascript for constraint binding, you cannot easily identify the restrictions that apply to a specific element. If the constraints are defined in <script> tag (hopefully adjacent to the element), it's a little easier but if the constraints are defined in another file you need to go find that file first.
