Electron Packager
Customize and package your Electron app with OS-specific bundles
Electron Packager is a command line tool and Node.js library that bundles Electron-based application source code with a renamed Electron executable and supporting files into folders ready for distribution. For creating distributables like installers and Linux packages, consider using either Electron Forge (which uses Electron Packager internally), or one of the related Electron tools, which utilizes Electron Packager-created folders as a basis. Note that packaged Electron applications can be relatively large. A zipped, minimal Electron application is approximately the same size as the zipped prebuilt binary for a given target platform, target arch, and Electron version (files named electron-v${version}-${platform}-${arch}.zip). Building an Electron app for the Windows target platform requires editing the Electron.exe file. Currently, Electron Packager uses node-rcedit to accomplish this. -

why-is-node-running
For when Node is running but you don't know why
why-is-node-running is a diagnostic tool for Node.js developers that helps answer the question: “why is my Node.js process still alive?” In complex asynchronous code — with timers, open handles, network sockets, file watchers, or unfulfilled promises — it can be tricky to figure out what is preventing the event loop from exiting. This utility inspects the active handles and resources in the runtime, prints a breakdown of open callbacks, sockets, timers, and other tasks, and explains what’s keeping Node running, helping you track down leaks or unintended resource retention. It’s particularly useful during testing, when you expect Node to exit after tests finish, or in long-running servers when you're debugging resource leaks or shutdown logic. By providing clear human-readable output that lists current handles and their origins, the tool dramatically reduces the time you would otherwise spend manually instrumenting your code. -

Percollate
A command-line tool to turn web pages into beautiful, readable PDF
Percollate is a command-line tool that turns web pages into beautifully formatted PDF, EPUB, or HTML files. By default, percollate processes URLs in parallel. Use the --wait option to process them sequentially instead, with a pause between items. The delay is specified in seconds, and can be zero. By default, percollate bundles all web pages in a single file. Use the --individual flag to export each source to a separate file. Additional CSS styles you can pass from the command line to override styles specified by the default/custom stylesheet. Generate a hyperlinked table of contents. The option is implicitly enabled when bundling more than one web page to a single file. Disable this implicit behavior by passing the --no-to flag. The idea with percollate is to make PDFs that can be printed without losing where the hyperlinks point to. However, for some link-heavy pages, the appended hrefs can become bothersome. -

GraphQL.js
A reference implementation of GraphQL for JavaScript
The JavaScript reference implementation for GraphQL, a query language for APIs created by Facebook. GraphQL.js is a general-purpose library and can be used both in a Node server and in the browser. As an example, the GraphiQL tool is built with GraphQL.js! Building a project using GraphQL.js with webpack or rollup should just work and only include the portions of the library you use. This works because GraphQL.js is distributed with both CommonJS (require()) and ESModule (import) files. Ensure that any custom build configurations look for .mjs files! For practical applications, you'll probably want to run GraphQL queries from an API server, rather than executing GraphQL with a command line tool. GraphQL.js provides two important capabilities: building a type schema and serving queries against that type schema. -

fx
Command-line tool and terminal JSON viewer
fx can work in two modes, cli and interactive. To start interactive mode pipe any JSON into fx. One of the frequent operations is mapping some function on an array. You can pass any number of anonymous functions for reducing JSON. fx provides a function save which will save everything in place and return saved object. This function can be only used with filename as first argument to fx command. Create .fxrc file in $HOME directory, and require any packages or define global functions. To be able require global modules make sure you have correct NODE_PATH env variable. If you need output other than JSON (for example arguments for xargs), do not return anything from the reducer. undefined value is printed into stderr by default. Sometimes it is necessary to omit some messages in JSON stream, or select only specified log messages. For this purpose, fx has special helpers select/filter, pass function into it to select/filter JSON messages.
