jQuery & Zepto Lazy
A lightweight, fast, feature-rich, powerful and highly configurable
Lazy is a fast, feature-rich, and lightweight delayed content-loading plugin for jQuery and Zepto. It's designed to speed up page loading times and decrease traffic to your users by only loading the content in view. You can use Lazy in all vertical and horizontal scroll ways. It supports images in img / tags and backgrounds, supplied with CSS like background-image, by default. On those elements, Lazy can set a default image or a placeholder while loading and supports retina displays as well. But Lazy is even able to load any other content you want by plugins and custom loaders. -

joi-router
Configurable, input and output validated routing for koa
Easy, rich, and fully validated koa routing. koa-joi-router returns a constructor that you use to define your routes. The design is such that you construct multiple router instances, one for each section of your application which you then add as koa middleware. The route definition for the currently matched route is available via ctx.state.route. This object is not the exact same route definition object that was passed into koa-joi-router, nor is it used internally - any changes made to this object will not have an effect on your running application but is available to meet your introspection needs. Validating the output body and/or headers your service generates on a per-status-code basis is supported. This comes in handy when contracts between your API and client are strict e.g. any change in response schema could break your downstream clients. In a very active codebase, this feature buys you stability. If the output is invalid, an HTTP status 500 will be used. -

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. -

lint-staged
Run linters on git staged files
Run linters against staged git files and don't let anything slip into your code base! Linting makes more sense when run before committing your code. By doing so you can ensure no errors go into the repository and enforce code style. But running a lint process on a whole project is slow, and linting results can be irrelevant. Ultimately you only want to lint files that will be committed. This project contains a script that will run arbitrary shell tasks with a list of staged files as an argument, filtered by a specified glob pattern. Linter commands work on a subset of all staged files, defined by a glob pattern. lint-staged uses micromatch for matching files. The concept of lint-staged is to run configured linter tasks (or other tasks) on files that are staged in git. lint-staged will always pass a list of all staged files to the task, and ignoring any files should be configured in the task itself. -

lowdb
Small local JSON database powered by Lodash
Small JSON database for Node, Electron and the browser. Powered by Lodash. You can use any of the powerful lodash functions, like _.get and _.find with shorthand syntax. Lowdb is perfect for CLIs, small servers, Electron apps and npm packages in general. It supports Node, the browser and uses lodash API, so it's very simple to learn. Actually, if you know Lodash, you already know how to use lowdb. lowdb doesn't support Cluster and may have issues with very large JSON files (~200MB). A UMD build is also available on unpkg for testing and quick prototyping. Database lodash instance. Use it to add your own utility functions or third-party mixins like underscore-contrib or lodash-id. With lowdb, you get access to the entire lodash API, so there are many ways to query and manipulate data. -

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. -

parrot-mocker-web
Simple web server to forward received requests to real servers
This project provides a simple mock server, which works with the Chrome plugin parrot-mocker. Install the Chrome plugin, parrot-mocker, so that your pages have the ability to intercept requests and forward to this mock server. Other usages without the plugin can refer to the parrot-mocker project. For example, if deployed in leancloud, please open your Chrome browser and visit the index page first. Other instances like now.sh are similar. Now you will find that requests are forwarded to the mock server, which are also visiable at index page. If visiting other pages in the same domain, their requests will also be forwarded to this mock server. -

pmxt
A unified API for trading across prediction markets
PMXT is a powerful, cross-platform terminal emulator and multiplexer designed to enhance productivity for command-line users by seamlessly blending terminal emulation with workspace management. It lets you run multiple shell sessions in panes and tabs, detach and reattach to workspaces, and persist session layouts—making it ideal for developers, sysadmins, and power users who juggle many concurrent tasks. PMXT also includes built-in features like customizable keybindings, layout presets, and scripting hooks so you can tailor your environment to your workflow without relying on external tools. Unlike simpler terminal emulators, it is built with session continuity in mind: you can close a window and later restore your exact layout and running processes without losing context. The project emphasizes performance and responsiveness, ensuring that even large logs, long-running compiles, and interactive workflows feel smooth and stable. -

react-native-picker-select
A Picker component for React Native for iOS and Android
A Picker component for React Native which emulates the native select interfaces for iOS and Android. For iOS, by default we are wrapping an unstyled TextInput component. You can then pass down styles to customize it to your needs. For Android, by default we are using the native Picker component. If you prefer, you can set useNativeAndroidPickerStyle to false, which will also render an unstyled TextInput component. You can then pass down styles to customize it to your needs. For either platform, you can alternatively pass down a child element of your choice that will be wrapped in a touchable area. The component defaults to using the native Android Picker in its un-selected state. Setting this flag to false will mimic the default iOS presentation where a tappable TextInput is displayed. -

tmi.js
Javascript library for the Twitch Messaging Interface
Connect to and interact with Twitch chat (IRC) from Node.js or a browser. Control the delay in milliseconds between JOIN requests when using the channels array option. Minimum of 300 milliseconds. If the identity has special permission from Twitch for a higher join rate then you should implement your own calls to the client.join method. Disable receiving JOIN/PART events for other users. Good for decreasing network traffic when joining lots of channels or you don't care about this data. After a threshold per channel Twitch stops sending this data so it may not be necessary for all cases. Channels to automatically join upon connecting. The rate of joins is controlled by the options.joinInterval option. Automatically reconnect the client if it gets disconnected for any reason. Sometimes Twitch will request the client to reconnect and tmi.js will disconnect and reconnect even if this option is set to false. -
