Moment.js
Parse, validate, manipulate, and display dates in javascript
Moment is a JavaScript date and time library that simplifies parsing, formatting, arithmetic, and humanizing of dates. It supports many formats in input and output, internationalization (i18n), locale-based month/day names, relative time (for example, “3 days ago”), and chaining of operations (adding, subtracting, diffing). Developers often use it for calendar displays, scheduling, and manipulating times across time zones or daylight saving transitions. While it makes working with date strings convenient, moment maintains internal mutability, which has trade-offs with safety and chainability. Over time, newer alternatives with immutable and modular designs have emerged, but moment remains widely known and integrated in many legacy projects. Its comprehensive feature set and ease of use made it a standard for date-time handling in JavaScript for many years. -

NodeGit
Native Node bindings to Git
Asynchronous native Node bindings to libgit2. NodeGit will work on most systems out-of-the-box without any native dependencies. If you receive errors about libstdc++, which are commonly experienced when building on Travis-CI, you can fix this by upgrading to the latest libstdc++-4.9. If you wish to help contribute to NodeGit it is useful to build locally. If you encounter errors, you most likely have not configured the dependencies correctly. You will need libpcre, libpcreposix, libkrb5, libk5crypto, and libcom_err libraries installed on your Linux machine. When building locally, you will also need development packages for kerberos and pcre, so both pcre-config, and krb5-config utilities must be present on your machine. -

Platformatic
Platformatic Open Source monorepo
Platformatic enables developers to efficiently develop and run APIs at scale. Historically, API developers have had to repetitively build infrastructure to satisfy foundational requirements, like authentication, authorization, caching, and connection to databases, and have had to manage microservices with technologies such as service mesh or centralized registries. This work is time consuming, undifferentiated, and painstakingly complex. With growing demands of SaaS applications, the amount of API permutations has grown exponentially and has become a development bottleneck. This has led large organizations to create dedicated platform API engineering teams to help teams deliver on business demands. Our goal is to make API development simple: we aim is to remove all friction from the day-to-day of backend developers. Platformatic is a series of Open Source tools to build APIs. -

Playwright CLI
CLI for common Playwright actions
Playwright CLI is the official command-line interface for Playwright, a powerful cross-browser automation and end-to-end testing framework that lets developers write and run tests reliably across Chromium, WebKit, and Firefox. The CLI provides an easy entry point for creating new test projects, running test suites, generating test traces, and debugging issues directly from the terminal. Developers can scaffold test files, record browser interactions as code, and run tests in headless or headed modes without needing a complex setup, dramatically reducing the barrier to writing robust UI tests. Playwright-CLI includes utilities for running tests in parallel across multiple devices, capturing screenshots and videos on failures, and outputting detailed reports that help diagnose flaky behavior or regressions. It also integrates with CI/CD pipelines, making it simple to automate testing as part of build and deployment workflows. -

Pure.css
A set of small, responsive CSS modules that you can use
A set of small, responsive CSS modules that you can use in every web project. Pure is ridiculously tiny. The entire set of modules clocks in at 3.7KB* minified and gzipped. Crafted with mobile devices in mind, it was important to us to keep our file sizes small, and every line of CSS was carefully considered. If you decide to only use a subset of these modules, you'll save even more bytes. Pure builds on Normalize.css and provides layout and styling for native HTML elements, plus the most common UI components. It's what you need, without the cruft. Pure is responsive out of the box, so elements look great on all screen sizes. Pure has minimal styles and encourages you to write your application styles on top of it. It's designed to get out of your way and makes it easy to override styles. By using Grids, Menus, and more, it's easy to create beautiful responsive layouts for all screen sizes. We've made it easy for you to get started. -

Razzle
Create server-rendered universal JavaScript applications
JavaScript applications are tough to setup. Either you buy into a framework, fork a boilerplate, or set things up yourself. Aiming to fill this void, Razzle is a tool that abstracts all complex configuration needed for both SPA's and SSR applications into a single dependency--giving you the awesome developer experience of create-react-app, but then leaving the rest of your app's architectural decisions about frameworks, routing, and data fetching up to you. With this approach, Razzle not only works with React, but also Preact, Vue, Svelte, and Angular, and most importantly, whatever comes next. Razzle has many examples, we might have one that fits your needs. You don't need to worry about setting up multiple webpack configs or other build tools. Just start editing src/App.js and go! If you have issues with css this might be related to postcss being resolved wrong. -

Semiotic
A data visualization framework combining React & D3
Semiotic is a data visualization framework combining React & D3. It provides three types of frames XYFrame, OrdinalFrame, NetworkFrame, to deploy a wide variety of charts. XY data i.e. line charts and scatterplots. Categorical data i.e. bar charts, violin plots, parallel coordinates. Topological and network data i.e. flow diagrams, network visualization, and hierarchical views. A guide for creating a line chart, timeseries, difference line, and line percents using XYFrame along with hover behavior, responsive dimensions, and styling. XYFrame takes lines as an object or an array of objects. Each object represents a line. Every object needs a coordinates property with the array of points for that line. The points will be rendered in the order of that array. You can use a key other than coordinates by changing the lineDataAccessor props. -

Sequelize
A promise-based multi SQL dialect Node.js ORM
Sequelize is a promise-based Node.js ORM for Postgres, MySQL, MariaDB, SQLite and Microsoft SQL Server. It features solid transaction support, relations, eager and lazy loading, read replication and more. Sequelize follows SEMVER. Supports Node v6 and above to use ES6 features. Sequelize v5 was released on March 13, 2019. Official TypeScript typings are now included. Sequelize can be used since the beginning in order to automate the creation of every table in your database. Models are the essence of Sequelize. A model is an abstraction that represents a table in your database. In Sequelize, it is a class that extends Model. The model tells Sequelize several things about the entity it represents, such as the name of the table in the database and which columns it has (and their data types). -

Source Map Support
Adds source map support to node.js (for stack traces)
Source Map Support is a Node.js module that enhances stack traces for transpiled or bundled JavaScript by resolving them back to the original source files using source maps. When code is compiled from TypeScript, CoffeeScript, Babel, or bundlers like Webpack, errors normally point to the generated code; this module intercepts V8’s stack trace API and remaps paths and line numbers to their original locations. The output closely mimics Node’s native stack format, so it feels like standard stack traces—but with your original source filenames and line numbers instead of opaque build artifacts. It’s designed to be easy to enable: you can require it programmatically or load it via a register hook so that all subsequent errors benefit. Because it relies on the source-map library, it works across a wide range of build systems that emit standard source maps. -

State Transition Plugin for Phaser
State transition plugin for Phaser.js
Phaser State Transition is a plugin that facilitates smooth transitions between game states in Phaser. It allows developers to define custom animations and easing functions when switching scenes, enhancing the visual flow of games. -

SuperAgent
Ajax for Node.js and browsers (JS HTTP client)
SuperAgent is light-weight progressive ajax API crafted for flexibility, readability, and a low learning curve after being frustrated with many of the existing request APIs. It also works with Node.js! Small progressive client-side HTTP request library, and Node.js module with the same API, supporting many high-level HTTP client features. Browser-ready versions of this module are available via jsdelivr, unpkg, and also in the node_modules/superagent/dist folder in downloads of the superagent package. If you are using browserify, webpack, rollup, or another bundler, then you can follow the same usage as Node. SuperAgent is easily extended via plugins. The Node client supports making requests to Unix Domain Sockets. DELETE, HEAD, PATCH, POST, and PUT requests can also be used, simply change the method name. Absolute URLs can be used. In web browsers absolute URLs work only if the server implements CORS. -
21
Svelte
Cybernetically enhanced web apps
Svelte is a new way to build web applications. It's a compiler that takes your declarative components and converts them into efficient JavaScript that surgically updates the DOM. Svelte shifts as much work as possible out of the browser and into your build step. No more manual optimizations, just faster, more efficient apps. Write breathtakingly concise components using languages you already know, HTML, CSS, and JavaScript. Oh, and your application bundles will be tiny as well. Built-in scoped styling, state management, motion primitives, form bindings and more — don't waste time trawling npm for the bare essentials. It's all here. -

Underscore.js
JavaScript's utility belt
Underscore.js is a JavaScript utility-library created by Jeremy Ashkenas that provides a broad set of functions for working with arrays, objects, functions, and other data types — essentially a “utility belt” for functional programming in JS. Instead of extending built-in objects or modifying prototypes, Underscore provides its helpers in a single _ namespace, enabling cross-browser support and consistent behaviour across environments. It offers map/filter/reduce, deep-cloning, templating, object traversal, function binding, and more, which makes it easier to write concise, expressive code rather than verbose loops and conditional logic. Many other libraries and frameworks (including Backbone) historically depended on or partnered with Underscore for their utility functions. Even though ES6+ and Lodash have overshadowed some of its role, Underscore remains influential and educational for how to design utility APIs. -

V Programming Language
Simple, fast, safe, compiled language for developing software
Simple language for building maintainable programs. You can learn the entire language by going through the documentation over a weekend, and in most cases, there's only one way to do something. This results in simple, readable, and maintainable code. Despite being simple, V gives a lot of power to the developer and can be used in pretty much every field, including systems programming, webdev, gamedev, GUI, mobile, science, embedded, tooling, etc. V avoids doing unnecessary allocations in the first place by using value types, and string buffers, promoting a simple abstraction-free code style. Most objects (~90-100%) are freed by V's auto-free engine: the compiler inserts necessary free calls automatically during compilation. A remaining small percentage of objects is freed via GC. The developer doesn't need to change anything in their code. "It just works", like in Python, Go, or Java, except there's no heavy GC tracing everything or expensive RC for each object. -
