js-ipfs-http-client-lite
An alternative client library for the IPFS HTTP API
An alternative client library for the IPFS HTTP API, aiming to be as lightweight as possible (<20KB) in the browser. To interact with the API, you need to have a local daemon running. It needs to be open on the right port. 5001 is the default and is used in the examples below, but it can be set to whatever you need. In a web browser IPFS HTTP client (either browserified or CDN-based) might encounter an error saying that the origin is not allowed. This would be a CORS ("Cross Origin Resource Sharing") failure: IPFS servers are designed to reject requests from unknown domains by default. You can whitelist the domain that you are calling from by changing your ipfs config. -

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. -

just-dashboard
Dashboards using YAML or JSON files
Dashboards using YAML or JSON files. Create a public GitHub gist with a file named dashboard.yml or dashboard.json (depending on your preferred format) As your dashboard is just data, you can generate it instead of repeating yourself. You can do that by generating the YAML or JSON file yourself, or you can use jq queries in your YAML file. And one with a dashboard that contains a component that can fetch the data from other other gist and turn it into 3 different charts. Using the same principle, you can also loads parts from your dashboard from other files, or just JSON/CSV data for specific charts. Suppose you are only interested in comparing foods by how much they contain of a single macronutrient. However, you want to be able to decide which macronutrient. -

layui
Classic modular front-end UI framework
Created by professional front-end, for full-level front-end and back-end developers, a low-threshold, out-of-the-box front-end UI solution. Layui (homonym: UI-like) is a front-end UI framework written with its own module specifications, following the writing and organization of native HTML/CSS/JS, with a very low threshold and ready to use. Its exterior is minimalist, but it does not lose its fullness. The volume is light and the components are abundant. Every detail from the core code to the API has been carefully crafted, which is very suitable for the rapid development of the interface. The first version of layui was released in the golden autumn of 2016. It is different from those UI frameworks based on the underlying MVVM. -

lightcrawler
Website crawler that audits site pages automatically with Lighthouse
Lightcrawler is a command-line tool designed to crawl a website and run automated audits on the discovered pages using Google Lighthouse. It works by starting from a given URL and recursively exploring linked pages to collect a set of pages that should be analyzed. Each discovered page is then evaluated using Lighthouse, which performs checks related to performance, accessibility, and web development best practices. This allows developers to audit multiple pages of a site automatically instead of manually running Lighthouse on each individual page. Lightcrawler supports configuration through a JSON configuration file, enabling users to customize how the crawler operates and which Lighthouse audits should be executed. Settings such as crawl depth and the number of concurrent browser instances can be configured to control how aggressively the crawler scans a site. It was created as a developer utility to help identify issues across an entire website more efficiently. -

linux-wasm
WebAssembly (Wasm) arch support for the Linux kernel
linux-wasm is an experimental project that ports the Linux kernel to run directly as a WebAssembly module, enabling a full Linux environment to boot and operate entirely inside a web browser without virtualization or cloud infrastructure. Instead of emulating Linux through a virtual machine, this project compiles the actual kernel for a WebAssembly target, allowing it to execute natively within a Wasm runtime. The system includes essential userland tools provided by BusyBox along with a lightweight libc implementation, making it possible to interact with a shell and execute basic commands in-browser. A terminal interface is implemented using web technologies, allowing users to experience a functioning Linux system through a standard web page. The project includes scripts to build and run the environment either locally, in containers, or directly in the browser, demonstrating flexibility in development workflows. -

marko
A declarative, HTML-based language that makes building web apps fun
A declarative, HTML-based language that makes building web apps fun. If you know HTML, CSS, and Javascript, you know Marko. Streaming, partial hydration, an optimizing compiler, & a small runtime. Start with simple HTML templates and add powerful components as needed. Marko is powering high-traffic websites like ebay.com. Marko is HTML re-imagined as a language for building dynamic and reactive user interfaces. Just about any valid HTML is valid Marko, but Marko extends the HTML language to allow building modern applications in a declarative way. Marko streams content to your users as soon as it’s ready. No waiting for client side JavaScript bundles or data requests to start rendering. HTML, assets, and images are loaded as soon as possible with asynchronous data loading in as it completes. Marko only sends the code for interactive components to the browser. Its compiler automatically detects which components only need to be rendered on the server. -

matchMedia() polyfill
matchMedia polyfill for testing media queries in JS
matchMedia() polyfill is a JavaScript polyfill that brings matchMedia-style media query testing to environments that need compatibility support. It lets developers test whether a CSS media type or media query applies directly from JavaScript. The library is useful for responsive behavior that depends on screen size, device type, orientation, or other media query conditions. It can be used with a companion addListener polyfill when code needs to react to changes over time. The project was used by tools such as Respond.js, FormFactor, and Modernizr, which reflects its role in older responsive web development workflows. It is most relevant for legacy browser support, educational reference, and projects that need to understand how JavaScript-based media query testing worked before broad native support. -

node-red-contrib-custom-chatgpt
Node-RED ChatGPT
A Node-RED node that interacts with OpenAI machine learning models like "ChatGPT". Install with the built-in Node-RED Palette manager. When editing the properties of the node, to get your OPENAI_API_KEY log in to ChatGPT. Create a new secret key" then copy and paste the "API key" into the node API_KEY property value. msg.payload should be a well-written prompt that provides enough information for the model to know what you want and how it should respond. Its success generally depends on the complexity of the task and quality of your prompt. A good rule of thumb is to think about how you would write a word problem for a middle schooler to solve. msg.payload should be a well-written prompt that provides enough information for the model to know what you want and how it should respond. -

pseudocode.js
Beautiful pseudocode for the Web
pseudocode.js is a JavaScript library that typesets pseudocode beautifully to HTML. Pseudocode.js takes a LaTeX-style input that supports the algorithmic constructs from LaTeX's algorithm packages. With or without LaTeX experience, a user should find the grammar fairly intuitive. The HTML output produced by pseudocode.js is (almost) identical to the pretty algorithms printed on publications that are typeset by LaTeX. Inserting math formulas in pseudocode.js is as easy as LaTeX. Just enclose the math expression in $...$ or \(...\). -

pure web3 browser
Personal immortal robot for the The Great Web
Personal immortal robot for the Great Web. The project is currently at the concept stage. The idea of addressing things using content addresses in browser makes sense, so it is worth working further on, and the idea of using cyber instead of google right in the browser search bar is also amazing. That is why our current focus is the launch of cyber network. Once we achieve that, we can shift more focus into the development of the browser. -

react-particle-effect-button
Bursting particle effect buttons for React
react-particle-effect-button is a React component library that provides buttons (or UI elements) with visually appealing particle explosion effects — for instance, on click or hover. Instead of static buttons, using this library lets you enhance user interactions with dynamic particle animations, giving a more lively and interactive UX. It’s ideal for use cases like “like” buttons, call-to-action buttons, or any UI control where you want a bit of flair. Because it’s built for React, integrating it into existing React applications/components is straightforward. The library hides the complexities of animations, particle rendering, and state handling, offering a simple API to developers. In this way, it brings a fancy, modern front-end feel to web apps with minimal effort. -
