Electron Context Menu
Context menu for your Electron app
Electron Context Menu is a JavaScript package that adds configurable right-click menus to Electron applications. It provides common native-style actions that Electron developers would otherwise need to implement manually. Built-in behavior includes cut, copy, paste, text lookup, web search, link copying, image actions, video actions, and spellchecking-related commands. An Inspect Element option can automatically appear during development for easier debugging. Developers can add, remove, reorder, rename, or transform menu actions and can target specific windows or views. The package operates from Electron's main process and can apply menus to existing and newly created windows. Its extensible API helps applications provide richer context-sensitive interactions with less custom menu code. -

Hotkeys JS
A robust Javascript library for capturing keyboard input
hotkeys-js is a tiny, framework-agnostic library for binding keyboard shortcuts in the browser, from simple key presses to complex combos and sequences. It provides a declarative API to register handlers like ctrl+k, shift+alt+p, or g g, and it normalizes key behavior across major browsers. The library includes scoping, so the same shortcut can trigger different actions depending on page context, and it offers filters to ignore inputs when the user is typing in form fields. You can enable or disable groups of shortcuts dynamically, making it well suited for SPAs and dashboard apps. Because it has no external dependencies and a small footprint, it drops easily into existing codebases. Its focus on developer ergonomics makes defining, managing, and cleaning up shortcuts straightforward. -

Inferno
React-like JavaScript library for building modern user interfaces
Inferno is an insanely fast, React-like library for building high-performance user interfaces on both the client and server. React-like API, concepts and component lifecycle events. Switch over easily with inferno-compat. One of the fastest front-end frameworks for rendering UI in the DOM, making 60 FPS on mobile possible. Isomorphic rendering on both client and server, along with fast-booting from server-side renders. Inferno doesn't have a fully synthetic event system like React does. Inferno has a partially synthetic event system, instead opting to only delegate certain events (such as `onClick`). Inferno doesn't support React Native. Inferno was only designed for the browser/server with the DOM in mind. Inferno doesn't support legacy string refs, use `createRef` or callback `ref` API. Inferno provides lifecycle events on functional components. This is a major win for people who prefer lightweight components rather than ES2015 classes. -

It supports Amazon marketplaces through Chrome, Firefox, and Safari, although its language heuristics are tuned primarily for English. -

Koa-OAI-Router
Koa Router, based on OpenAPI, Swagger and Json Schema
I have used Markdown and wiki to manage API doc, from which I have suffered a lot. It wastes too much time and is very boring. The document should be repaired when you change the API. It's very inconvenient to test and debug. The management of API doc totally depends on people. As a result, it is hard to make documents have high quality. Meanwhile, the developers will spend more time on testing, which may have a bad effect on the project.
