    documentation.js

    documentation.js

    Documentation for modern JavaScript

    A documentation system so good, you'll actually write documentation. documentation.js has pluggable output formats: you can get raw documentation as JSON, beautiful, customizable HTML, or Markdown that fits perfectly into an API.md or README.md file in a GitHub repository. Demos, self-documentation as HTML, Markdown, JSON. documentation.js aims to cover all flavors of modern JavaScript. documentation.js works in your workflow, whether you just want a command-line utility that generates documentation from your code, you use Gulp to publish websites, or you're building a new system and want low-level JavaScript methods. Infers parameters, types, membership, and more. Write less documentation: let the computer write it for you. Integrates with GitHub to link directly from documentation to the code it refers to.

    electron-dl

    electron-dl

    Simplified file downloads for your Electron app

    electron-dl is a JavaScript package that simplifies file downloading inside Electron desktop applications. It replaces substantial download-handling boilerplate with a small API that operates from Electron's main process. Files can be saved automatically to the user's Downloads directory or routed to another specified folder. The package handles multiple simultaneous downloads and can expose individual and combined progress information. Desktop integrations can display download progress and file-count badges on supported dock or taskbar icons. Developers can customize filenames, Save As dialogs, overwrite behavior, completion handling, cancellation, and error messages. It supports BrowserWindow and WebContentsView targets and currently requires Electron 30 or later.

    electron-store

    electron-store

    Simple data persistence for your Electron app or module

    Simple data persistence for your Electron app or module. Save and load user preferences, app state, cache, etc. Electron doesn't have a built-in way to persist user preferences and other data. This module handles that for you, so you can focus on building your app. You can use this module directly in both the main and renderer process. For use in the renderer process only, you need to call Store.initRenderer() in the main process, or create a new Store instance (new Store()) in the main process. Changes are written to disk atomically, so if the process crashes during a write, it will not corrupt the existing config. Under the hood, the JSON Schema validator ajv is used to validate your config. We use JSON Schema draft-07 and support all validation keywords and formats. You should define your schema as an object where each key is the name of your data's property and each value is a JSON schema used to validate that property.

    eslint-plugin-flowtype

    eslint-plugin-flowtype

    Flow type linting rules for ESLint

    Flow type linting rules for ESLint. This plugin exports a recommended configuration that enforces Flow type good practices. To enable this configuration use the extends property in your .eslintrc config file. ESLint is designed to be flexible and configurable for your use case. You can turn off every rule and run only with basic syntax validation or mix and match the bundled rules and your custom rules to fit the needs of your project. There are two primary ways to configure ESLint. Use JavaScript comments to embed configuration information directly into a file. Use a JavaScript, JSON, or YAML file to specify configuration information for an entire directory and all of its subdirectories. This can be in the form of a .eslintrc.* file or an eslintConfig field in a package.json file, both of which ESLint will look for and read automatically, or you can specify a configuration file on the command line.

    glsl-sandbox

    glsl-sandbox

    Shader editor and gallery

    GLSL Sandbox is an in-browser playground for writing and sharing fragment shaders with instant visual feedback. It provides a minimal editor and a fullscreen WebGL viewport so your shader takes center stage, making it perfect for learning, live-coding, and showcasing visual experiments. The environment injects a small set of uniforms—time, resolution, mouse—so you can animate and interact without boilerplate. A public gallery lets creators browse, fork, and remix shaders, turning the site into a collaborative learning hub. Because everything runs client-side, iteration is fast and portable—just load the page and start typing. It has become a staple tool in the creative-coding community, lowering the barrier to entry for shader art and GPU programming.

    iOS Location Spoofer

    iOS Location Spoofer

    Standalone iOS app to spoof GPS location without jailbreak

    iOS Location Spoofer is an unofficial iOS location modification project that works through proxy-based HTTPS interception instead of jailbreak tooling. It is based on earlier research that used a custom VPN and MITM proxy, but this repository ports the core logic to JavaScript for popular proxy apps. The project targets Shadowrocket, Surge, Loon, Quantumult X, and Stash through importable module or plugin files. It rewrites Apple location-service responses so the device calculates a chosen latitude and longitude. The repository also includes support for Wi-Fi and cellular tower coordinate rewriting, response-format compatibility handling, motion activity rewriting, and optional web-based location picking. Because it modifies device location behavior, it should only be used in legal, personal, and non-deceptive testing contexts.

    jQuery Google Maps Store Locator Plugin

    jQuery Google Maps Store Locator Plugin

    A store locator plugin using Google Maps API version 3

    This jQuery plugin takes advantage of Google Maps API version 3 to create an easy to implement store locator. No back-end programming is required, you just need to feed it KML, XML, or JSON data with all the location information. How you create the data file is up to you. I originally created this for a company that didn’t have many locations, so I just used a static XML file. You will need to geocode your locations beforehand or use a geocoding API service if you want to try to do it on the fly. The reason for this is that all free geocoding APIs have strict limits that would easily be exceeded. In the end, you're much better off storing the coordinates versus having to look them up for each location on each request.

    jsdoc-to-markdown

    jsdoc-to-markdown

    Generate markdown documentation from jsdoc-annotated javascript

    Generates markdown API documentation from jsdoc annotated source code. Useful for injecting API docs into project README files. By default, dmd generates github-flavored markdown. Not all markdown parsers render gfm correctly. If your generated docs look incorrect on sites other than Github (e.g. npmjs.org) try enabling this option to disable Github-specific syntax. Two options to render parameter lists: 'list' or 'table' (default). Table format works well in most cases but switch to list if things begin to look crowded / squashed. By default, the output of each invocation of the main generation methods (render, getTemplateData etc) is stored in the cache (your system's temporary directory). Future jsdoc2md invocations with the same input options and source code will return the output immediately from cache, making the tool much faster/cheaper. If the input options or source code changes, fresh output will be generated.

    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.

    next-firebase-auth

    next-firebase-auth

    Simple Firebase authentication for all Next.js rendering strategies

    Simple Firebase authentication for all Next.js rendering strategies. This package makes it simple to get the authenticated Firebase user and ID token during both client-side and server-side rendering (SSR). We treat the Firebase JS SDK as the source of truth for auth status. When the user signs in, we call an endpoint to generate a refresh token and store the user info, ID token, and refresh token in cookies. Future requests to SSR pages receive the user info and ID token from cookies, refreshing the ID token as needed. When the user logs out, we unset the cookies. This package will likely be helpful if you're using Firebase authentication and expect to use server-side rendering—especially if you need access to Firebase ID tokens on the server side. If your app only uses static pages or doesn't need the Firebase user for SSR, use the Firebase JS SDK directly to load the user on the client side.

    nightTab

    A neutral new tab page accented with a chosen colour

    A neutral new tab page accented with a chosen color. Customize the layout, style, background and bookmarks with nightTab. Make the browser start page dark (or light, or anything in between). Do not access user information. This means nightTab will not request browser permissions. Aim to make everything on the user interface, within reason, customizable. Aim to make the user experience easy while supporting the above. Keep nightTab open source. Sharing the look and feel of one Bookmark to another can be achieved when editing a single Bookmark. The Bookmark edit modal has three options to copy settings to other Bookmarks. These checkboxes can be found at the bottom of the Visual & Name, Layout and Theme tab. Development and testing is only conducted on Chrome and Firefox. The performance and reliability of nightTab on other browsers is out of the scope of this project.

    nivo

    A rich set of dataviz components

    nivo provides a rich set of dataviz components, built on top of the awesome d3 and Reactjs libraries. Several libraries already exist for React d3 integration, but just a few provide server side rendering ability and fully declarative charts. In order to use nivo, you have to install the @nivo/core package and then choose some of the scoped @nivo packages according to the charts you wish to use. Given an array of data series having an id and a nested array of points (with x, y properties), it will compute the line for each data series. All datum having null x or y will be treated as holes, thus portions of the corresponding line will be skipped. You can fully customize it using the circleComponent property to define your own, if you wish to do so you should have a look at the default SVG component to get started. Bar chart which can display multiple data series, stacked or side by side. Also supports both vertical and horizontal layout, with negative values descending below the x axis.
