    JSON:API

    JSON:API

    A specification for building JSON APIs

    This repository defines the specification for JSON:API, a standardized format for building APIs with JSON. The goal is to minimize bikeshedding and inconsistency by giving developers a well-documented schema for requests and responses. It specifies how to represent resources, relationships, pagination, sorting, filtering, and metadata in a predictable way. Clients and servers that follow the spec can interoperate seamlessly without custom glue code for every new service. JSON:API also emphasizes efficiency, recommending ways to reduce payload size and minimize the number of requests. Over time it has become a widely adopted contract for RESTful APIs, helping teams save time and avoid fragmentation across microservices and third-party integrations.

    Polka

    Polka

    A micro web server so fast, it'll make you dance

    Polka is a micro web server for Node.js that positions itself as an extremely minimal yet highly performant alternative to Express. Under the hood it is essentially a thin layer on top of Node’s native HTTP server, adding just enough routing, middleware, and sub-application support to be productive without the weight of a full framework. Its API is intentionally similar to Express, which makes it easy for existing Express users to migrate or share middleware with minimal changes. Because it focuses on speed and small size, polka can be attractive for performance-sensitive services, serverless functions, or applications where dependency budgets are tight. The project exposes common features like route parameters, query parsing (usually via external middleware), and simple error handling, but leaves more advanced concerns to the user or ecosystem packages.

    PurifyCSS

    PurifyCSS

    Remove unused CSS. Also works with single-page apps

    A function that takes content (HTML/JS/PHP/etc) and CSS, and returns only the used CSS. PurifyCSS does not modify the original CSS files. You can write to a new file, like minification. If your application is using a CSS framework, this is especially useful as many selectors are often unused. Statically analyzes your code to pick up which selectors are used. The CLI currently does not support file patterns. Remove unused CSS code from your stylesheet. PurifyCSS is meant to be installed via npm and built into your build process using tools like Grunt, Gulp or Webpack. However if you're using a different development stack or building your sites with a CMS like Wordpress, you can use the online tool to clean up your stylesheet. Especially if you are using CSS frameworks like Bootstrap or a multi-purpose Wordpress theme, chances are you are actually using less than 20% of the defined CSS rules.

    DOMPurify

    DOMPurify

    XSS sanitizer for HTML, MathML and SVG

    A DOM-only, super-fast, uber-tolerant XSS sanitizer for HTML, SVG and MathML. It's also very simple to use and get started with. DOMPurify was started in February 2014 and, meanwhile, has reached version 2.3.0. DOMPurify is written in JavaScript and works in all modern browsers (Safari (10+), Opera (15+), Internet Explorer (10+), Edge, Firefox and Chrome - as well as almost anything else using Blink or WebKit). It doesn't break on MSIE6 or other legacy browsers. It either uses a fall-back or simply does nothing. Our automated tests cover 17 different browsers right now, more to come. We also cover Node.js v14.15.1, v15.4.0, running DOMPurify on jsdom. Older Node.js versions are known to work as well. DOMPurify is written by security people who have vast background in web attacks and XSS.

If an input element is used as the filter element, the table will be filtered in real-time as the user types in the input element. To prevent excessive redrawing of the table Tabulator will wait 300 milliseconds after the user has finished typing before triggering the filter.

    layui

    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.

    pdfmake

    pdfmake

    Client/server side PDF printing in pure JavaScript

    Print PDFs directly in the browser or delegate it to your NodeJS backend. Use the same document definition in both cases. Forget about manual x, y calculations.

Provides a set of options to disable font layout cache and to control when pages are flushed to the output file. Pdfmake is runnable in browser (client-side) and in Node.js (server-side). PDF name can be defined only by using metadata title property. Add-ons used in browsers can affect the functionality of pdfmake (especially for open() and print()). If pdfmake is not working try disable add-ons in browser. The supported browsers are Internet Explorer 10+, Edge 12+, Firefox, Chrome, Opera and Safari.

    7.css

    7.css

    A JS-independent, tree-shakeable CSS framework

    7.css is a CSS framework for building interface components that look like Windows 7. It is built on top of the GUI backbone of XP.css, which is an extension of 98.css. This framework relies on the usage of semantic HTML. To make a button, you'll need to use a button. Input elements require labels. Tabs rely on the role="tab" attribute. This page will guide you through that process, but accessibility is a primary goal of this project. It does not ship with any JavaScript, so it is compatible with your frontend framework of choice.

    Compile LaTeX, knitr, literate Agda, literate Haskell, or Pweave documents from within Atom. Use the Atom package manager and search for "latex", or run apm install latex from the command line. A reasonably up-to-date and working TeX distribution is required. The only officially supported distributions are TeX Live and MiKTeX. Although, the latter is not as well tested and supported as TeX Live, hence using TeX Live is highly recommended. You need to ensure that the package can find your TeX distribution's binaries; by default, the package uses your PATH environment variable, as well as the following search paths on Linux and macOS.

    CF-Workers-docker.io

    CF-Workers-docker.io

    Docker Warehouse Image Proxy Tool

    CF-Workers-docker.io is a project by cmliu that sets up a proxy for Docker Hub (and potentially other container image registries) using Cloudflare Workers, effectively acting as a middle-man mirror to improve image pull reliability and speed in regions where direct access is degraded. The idea is to intercept registry requests, reroute or mirror them through a worker endpoint, and therefore bypass regional limitations or firewall blocks affecting official Docker registries. Users can deploy their own copy of this proxy, point their Docker daemon’s registry-mirrors configuration to it, and benefit from an accelerated and more accessible image pull experience. The project’s README warns about possible policy risks—since Cloudflare’s terms forbid use of Workers for VPN or similar proxy services, so users deploy at their own risk. It also includes instructions for setting up both Docker daemon and containerd/podman equivalents by customizing configuration files.
