FileSaver.js
An HTML5 saveAs() FileSaver implementation
Have you ever wanted to add a Save as… button to a webapp? Whether you’re making an advanced WebGL-powered CAD webapp and want to save 3D object files or you just want to save plain text files in a simple Markdown text editor, saving files in the browser has always been a tricky business. Usually when you want to save a file generated with JavaScript, you have to send the data to your server and then return the data right back with a Content-disposition: attachment header. This is less than ideal for webapps that need to work offline. The W3C File API includes a FileSaver interface, which makes saving generated data as easy as saveAs(data, filename), though unfortunately it will eventually be removed from the spec. With FileSaver.js, which implements FileSaver in all modern browsers, it’s possible to generate any type of file you want right in the browser, document editors can have an instant save button that doesn’t rely on an online connection. -

MobX
A Simple, scalable state management
MobX is a battle tested library that makes state management simple and scalable by transparently applying functional reactive programming (TFRP). Write minimalistic, boilerplate free code that captures your intent. Trying to update a record field? Use the good old JavaScript assignment. Updating data in an asynchronous process? No special tools are required, the reactivity system will detect all your changes and propagate them out to where they are being used. All changes to and uses of your data are tracked at runtime, building a dependency tree that captures all relations between state and output. This guarantees that computations depending on your state, like React components, run only when strictly needed. There is no need to manually optimize components with error-prone and sub-optimal techniques like memoization and selectors. -

Multiline
Multiline strings in JavaScript
Multiline is a small JavaScript utility created to make multiline strings easier to write before template literals became standard. It extracts the contents of a block comment placed inside an anonymous function and returns that text as a string. This avoids long chains of concatenated strings or arrays joined with newline characters. A stripIndent helper removes redundant leading indentation while preserving the intended layout. The package can be used for CLI help text, welcome messages, test fixtures, and multiline queries. It primarily targets Node.js, although it can also work in browsers with a bundler. The repository is archived and deprecated, and its own documentation recommends ES2015 template literals for modern code. -

P-Map
Map over promises concurrently
P-Map is a JavaScript utility for mapping over synchronous or asynchronous iterables while controlling concurrent promise execution. It is useful when the same async operation must process many inputs without starting every task at once. Unlike Promise.all, developers can set an explicit concurrency limit and choose how mapping errors should be handled. The library preserves input ordering in its returned results while allowing work to proceed concurrently. Its pMapIterable API streams completed mapped values through an async iterable and supports backpressure control. Operations can also be canceled with AbortSignal, while pMapSkip lets individual mapped values be omitted from the result. These controls make it suitable for network requests, queues, batch processing, and other resource-sensitive workloads. -

Passport
Simple, unobtrusive authentication for Node.js
Passport is a flexible authentication middleware for Node.js that provides a modular and extensible system for handling user login and identity in web applications. It doesn’t impose specific user model structures or storage strategies but instead offers a unified API driven by “strategies”—small plugins that encapsulate authentication logic for protocols such as local username/password, OAuth, OpenID, SAML, and many others. This design allows developers to plug in only the strategies they need and swap or add new ones without rewriting core application logic, making Passport highly adaptable for diverse authentication requirements. Passport hooks into Express (and similar frameworks) using middleware functions that run during the request lifecycle, simplifying tasks like session management, credential validation, and user serialization. -

ScreenCat
Webrtc screensharing electron app for mac os (Alpha)
The ScreenCat project is an open-source screen sharing and remote collaboration application built on Electron and WebRTC that lets users share their desktop and grant control of mouse and keyboard to remote participants. Originally designed for developers and tech enthusiasts rather than commercial use, it emphasizes hackability and contribution from the community. The software uses experimental Chromium WebRTC APIs to stream desktop video to another peer, and it supports remote control through a browser interface by sending a simple invite code. Although still in alpha status, it provides a rare open collaborative alternative to proprietary screen sharing solutions. The architecture includes native dependencies for simulating input events, enabling real-time remote control across systems. Users can also screenshare between two ScreenCat applications or with a normal web browser, making it versatile for remote assistance and pairing scenarios. -
17
Signale
Highly configurable logging utility
Hackable and configurable to the core, signale can be used for logging purposes, status reporting, as well as for handling the output rendering process of other node modules and applications. You can now support the development process through GitHub Sponsors. To create a custom logger define an options object yielding a types field with the logger data and pass it as argument to a new signale instance. By utilizing the secrets option, secrets and other sensitive information can be filtered out from the body as well as the metadata, i.e. scope names etc, of to-be-logged messages. The option is part of the configuration object passed to a Signale instance on its initialization, and is of type Array<String|Number>. The array can hold multiple secrets, all of which are removed, if present, from the to-be-logged messages and are replaced with the default '[secure]' string. -

SockJS-client
WebSocket emulation and Javascript client
SockJS is a browser JavaScript library that provides a WebSocket-like object. SockJS gives you a coherent, cross-browser, Javascript API which creates a low latency, full duplex, cross-domain communication channel between the browser and the web server. Under the hood SockJS tries to use native WebSockets first. If that fails it can use a variety of browser-specific transport protocols and presents them through WebSocket-like abstractions. SockJS is intended to work for all modern browsers and in environments which don't support the WebSocket protocol, for example, behind restrictive corporate proxies. SockJS-client does require a server counterpart, such as SockJS-node, which is a SockJS server for Node.js. The API should follow HTML5 Websockets API as closely as possible. All the transports must support cross domain connections out of the box. It's possible and recommended to host a SockJS server on a different server than your main web site. -

autotyper
A simple, lightweight JavaScript package for automatically typing text
A simple, lightweight JavaScript package for automatically typing text. Options can be passed via HTML data attributes. Either as individual properties or a single options object. The attribute names should be prefixed with 'autotyper' in param case. autotyper is written and compiled in a way that it should support the majority of browsers, old and new. However, these are the browsers for which we offer official support. Should you find a bug in the package, don't hesitate to submit an issue and we'll assist you as best we can. Text can be read directly from an element (SEO friendly). -

babel-minify
An ES6+ aware minifier based on the Babel toolchain (beta)
babel-minify is an experimental project that attempts to use Babel's toolchain (for compilation) to do something in a similar vein, minification. It's currently in 0.x, so we don't recommend using it in production. Current tools don't support targeting the latest version of ECMAScript. (yet). BabelMinify can because it is just a set of Babel plugins, and Babel already understands new syntax with our parser Babylon. When it's possible to only target browsers that support newer ES features, code sizes can be smaller because you don't have to transpile and then minify. When testing, it's recommended to run minifiers for production so less code is sent to end-users vs. in development where it can be an issue for readability when debugging. Options specific to a certain environment are merged into and overwritten non-env specific options. -
21
clipboardy
Access the system clipboard (copy/paste)
Clipboardy is a cross-platform JavaScript package for reading from and writing to the operating system clipboard. It provides asynchronous clipboard operations as well as synchronous methods where the platform supports them. Text copying and pasting works across macOS, Windows, Linux, OpenBSD, FreeBSD, Android through Termux, and modern browsers. Browser usage relies on the standard Clipboard API and therefore requires a secure context such as HTTPS. On macOS, the package also supports copying multiple image files, reading clipboard images into temporary files, and checking whether image data is present. Linux environments require an active X11 or Wayland display server rather than a headless session. The package provides one consistent interface across otherwise different operating-system clipboard implementations. -

elasticsearch-head
A web front end for an elastic search cluster
elasticsearch-head is a web front end for browsing and interacting with an Elastic Search cluster. elasticsearch-head is hosted and can be downloaded or forked at github. There are two ways of running and installing elasticsearch-head. Running as a plugin of ElasticSearch (this is the preferred method). And running as a standalone webapp. By default es-head will immediately attempt to connect to a cluster node at http://localhost:9200/. Enter a different node address in the connect box and click 'Connect' if required. A ClusterOverview, which shows the topology of your cluster and allows you to perform index and node level operations. A couple of search interfaces that allow you to query the cluster a retrieve results in raw json or tabular format. Several quick access tabs that show the status of the cluster. An input section that allows arbitrary call to the RESTful API to be made. This interface includes several options that can be combined to produce interesting results. -
23
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. -
24
gtop
System monitoring dashboard for terminal
gtop is a tool that helps you monitor your systems through a dashboard user interface, and it is optimized to monitor and visualize terminals. gtop requirements are to have Node.js version 8 or higher. It supports Linux, OSX, and Windows (with partial support). You need to assign host net and pid to access the metrics in the host machine. Start gtop with the gtop command. To stop gtop use q, or ctrl+c in most shell environments. You can sort the process table by pressing 'p' for Process Id, 'c' for CPU usage, and 'm' for Memory usage. If you see question marks or other different characters, try to run it with the environment variables provided in the documentation. gtop is released under the MIT license. -
