    jsblocks

    jsblocks

    Better MV-ish Framework

    From simple user interfaces to complex single-page applications using faster, server-side rendered, and easy-to-learn frameworks. jsblocks is fast but we will not stop here. We have ideas on how to make it even faster. Model-View-Controller, Model-View-Collection, Model-View-ViewModel, Model-View-Whatever, Hierarchical Model-View-Controller or nothing at all - jsblocks has you covered. A Model-View-Collection layer stands on top of the main DOM syncing core. This MVC layer is extremely powerful and enables easy creation of complex applications. The MVC layer is also modular, so you could remove it if you don't need the extra functionality, making your code base lighter. The debugging experience is a major factor that is often overlooked. It brings an easier learning curve and faster development cycles. This is why jsblocks concentrate a lot of effort on building a great debugging experience.

    uni-app

    uni-app

    A cross-platform framework using Vue.js

    uni-app is a cross-platform framework that lets developers build applications with Vue syntax and deploy them to multiple targets: iOS, Android, web (H5), and a range of mini-program ecosystems. It abstracts platform differences through a unified component and API layer, so most business logic and UI code can be shared across outputs. The tooling includes a CLI, IDE support, and a plugin market that provides native integrations, UI kits, and deployment helpers. Developers can choose between rendering engines and build modes to optimize for performance or compatibility per platform. The framework emphasizes rapid development with live preview, strong documentation, and scaffolds for common app patterns. In practice, uni-app is used to ship multi-surface apps quickly in markets where super-app mini-programs and mobile apps must coexist.

    Reagent

    Reagent

    A minimalistic ClojureScript interface to React.js

    Reagent is a minimalistic ClojureScript interface to React that enables developers to write efficient React components using plain ClojureScript functions and data, leveraging a Hiccup-like syntax and immutable state to simplify UI creation. React is pretty darn fast, and so is Reagent. It should even be faster than plain old javascript React a lot of the time, since ClojureScript allows us to skip a lot of unnecessary rendering (through judicious use of React's shouldComponentUpdate). The ClojureScript overhead is kept down, thanks to lots of caching. Code size is a little bigger than React.js, but still quite small. The todomvc example clocks in at roughly 79K gzipped, using advanced compilation.

    TodoMVC

    TodoMVC

    Helping you select an MV* framework

    TodoMVC is a project that helps developers choose an MV* framework by providing a structured way of comparing JS libraries and frameworks. These days there are so many MV* frameworks developers can choose from to structure and organize JavaScript web apps. TodoMVC helps developers navigate through this sea of choices on the basis of actual project code, so they can choose which one matches them and their needs best. TodoMVC has been called the 'Speed-dating' and 'Rosetta Stone' of MV* frameworks, however there may be more that certain frameworks are capable of. The best way to use TodoMVC is to invest time in researching its offered solutions in greater depth before opting for them.

    Tracing Framework

    Tracing Framework

    Web Tracing Framework libraries and extensions

    The Web Tracing Framework (WTF) is an open source suite of tools, libraries, and visualizers created by Google to help developers analyze and optimize the performance of complex web applications. By adding lightweight instrumentation to their code, developers can trace execution flow, identify bottlenecks, and detect performance regressions. The framework provides fine-grained insights into application behavior, making it particularly useful for achieving smooth, high-performance experiences, such as maintaining 60fps animations in web interfaces. It includes visualization tools that allow for detailed analysis of timing, resource usage, and event flow, enabling developers to diagnose and fix inefficiencies effectively. While still experimental, WTF is designed to be extensible and community-driven, encouraging contributions and adaptations for various types of web applications.

    goober

    goober

    A less than 1KB css-in-js solution

    As the subtitle notes, this is the smallest and fullest featured css-in-js solution out there. Weighing at 1KB and once bundled it's gonna be less due to tree-shake. goober does more with less! Since the code measure less in size, it's served, read and ran quicker. goober is built on the shoulders of well-established solutions. That means the API has been paved and we need to follow it. You'll find as, forwarded, CSS, keyframes, styled and so much more. Easily access your common sizes, colors, and anything really with the use of a theme. On the server, you can easily extract the CSS for the current state with extractCss. The initial thought of goober was a CSS-in-js solution at the cost of peanuts. Hence the peanuts emoji. By using goober, you are practically getting back space in size to build more of the needed features.

    neo.mjs

    neo.mjs

    The application worker driven frontend framework

    neo.mjs is the next-generation UI framework for creating desktop & mobile Web Apps. It has a very strong focus on performance and creating scalable & modular architectures. A clean & consistent API, as well as the ability to run without any build processes, will increase the productivity of your team while creating better solutions at the same time. While current libraries/frameworks like Angular, React or Vue provide reasonable performance for small or mostly static Apps, they lack when it comes to big Apps or complex Components. The problem is, that most Apps today run within a single thread (CPU), while each computer or mobile device has several CPUs available. Some Apps move expensive tasks into separate threads, but this is by far not enough. Using neo.mjs, most parts of the framework as well as the Apps which you create with it, run inside a separate thread. This architecture leaves the main thread mostly idle, so it can fully concentrate on its purpose.

    Advanced REST Client application

    Advanced REST Client application

    Advanced REST Client - Desktop application

    This is the main repository for the ARC Electron application. If you are still using Chrome plug-in then proceed to move From Chrome To the Desktop Client section. The original Chrome application is discontinued as Chrome stopped supporting browser-based applications. ARC was built as an open-source and free for everyone API tool out of a passion for giving the developer community tools they need. The application and related projects (like API Console) are created and distributed to our users for free. Our vision is that API tools are available for every developer and organization, regardless of their size, for free and without forced relationship. API tools are using open standards to communicate with other applications so developers can build integrations. Originally the application was created by the author for own convenience while developing APIs. It quickly turned out to be a common problem among developers to consume APIs during the development process.

    Bootbox

    Bootbox

    Wrappers for JavaScript alert(), confirm() and other flexible dialogs

    Bootbox.js is a small JavaScript library which allows you to create programmatic dialog boxes using Bootstrap modals, without having to worry about creating, managing, or removing any of the required DOM elements or JavaScript event handlers. Bootbox provides three functions, alert, confirm, and prompt, whose aim is to mimic their native JavaScript equivalents. Each Bootbox function calls a fourth public function, dialog, which you can use to create your own custom dialogs. See the Documentation for usage and to learn which options are available for each function. Tests are run using Karma using the Mocha test adapter. To run the tests yourself, simply run npm install within the project followed by npm test. Please note that this will require PhantomJS being installed and in your path - if it is not, you may run the tests and capture browsers manually by running karma start from the root of the project.
