    BlurAdmin

    BlurAdmin

    AngularJS Bootstrap admin panel framework

    Blur admin is completely free and MIT licensed. That means you can do whatever you want with it. Initially we planned to sell it on template markets. But they rejected us several times. That's why we decided to make it open-source. And honestly, we have completely no regrets about it! And we suggest you to not waste your money and use our template instead of paid ones! Trust us, it's better than large number of them. Feature-based structure has proven itself as a good choice for large angular applications. We have put a lot of efforts and carefully selected each color and character for this template! Blur admin is Angular front-end Admin Dashboard template. That means all data you can see on graphs, charts tables is hardcoded in Javascript. You can use any backend you want with it without limitations.

    Bootlint

    Bootlint

    HTML linter for Bootstrap projects

    Bootlint is a tool that checks for several common HTML mistakes in webpages that are using Bootstrap in a fairly "vanilla" way. Vanilla Bootstrap's components/widgets require their parts of the DOM to conform to certain structures. Bootlint checks that instances of Bootstrap components have correctly structured HTML. Optimal usage of Bootstrap also requires that your pages include certain <meta> tags, an HTML5 doctype declaration, etc.; Bootlint checks that these are present. Bootlint assumes that you are using Bootstrap's default class names in your webpage, as opposed to taking advantage of the "mixins" functionality of Less or Sass to map them to custom class names. If you are using mixins, Bootlint may report some false-positive warnings. However, there are some Bootlint checks that are applicable even if you are using mixins pervasively.

    Bootstrap Native

    Bootstrap Native

    If you are looking for Bootstrap without jQuery, this is it.

    The lighter and more compact set of JavaScript components for Bootstrap is sourced with a modern ES6+ codebase and strong TypeScript definitions. At about half the size of the original and around 12kb gZipped, this library does most of Bootstrap & Popper combined. We launched the project back in 2015 with the goal of debunking the "write less do more" myth, meanwhile the Bootstrap developers themselves have decided to drop jQuery, however, we decided to keep maintaining the project for its many benefits and the learning experience. If you mainly use Bootstrap plugins for your projects, why not use a much lighter, potentially faster library, see a different perspective on the same challenges, interact with a less crowded community, and get a better chance to learn or say hi! The Alert component covers the specific original events and public methods, but just like the original plugin, does not provide any initialization option.
