Day.js
Fast, immutable 2kB alternative to Moment.js with the same modern API
Day.js is a fast, immutable, minimalist JavaScript library for parsing, validating, manipulating, and displaying dates and times for modern browsers. Its API is largely compatible with that of Moment.js, so if you know how to use Moment.js you’ll know how to use Day.js. Why opt for Day.js? Because it’s at just 2kB it involves less JavaScript to download, parse and execute, and more time for your code. Day.js is also immutable, chainable and has great support for internationalization. It currently supports all browsers. -

Device Motion Gesture for JavaScript
JavaScript library for recording and recognising device gestures.
A JavaScript library for detecting gestures made by the user whilst holding their mobile device. The software converts the continual stream of motion readings into distinct gesture events. All you need to do is attach event-handlers to the gestures. Your functions get called when the user makes the gesture with the device. The library comes with some pre-recorded gestures. You can also record your own custom gestures using the recorder application. NOTE: This library recognises gestures made by moving the hand-held device in your hand. It does not recognise gestures from video or images. -

Dumper.js
A better and pretty variable inspector for your Node.js applications
Dumper.js is a small JavaScript utility for pretty-printing or serializing JavaScript objects and data structures in a human-readable, tree-like format — useful for debugging, logging, or inspecting complex nested data. When you pass an object (or array, or nested structure) through dumper.js, it outputs a representation that shows keys, nested depth, and structure clearly, making it easier to understand what’s inside compared to default JSON dumps or console.log clutter. This can be especially helpful when dealing with large objects, deeply nested responses, or when you need to inspect something quickly without building custom serializers. The utility is minimal and straightforward: you import it, pass your data, and get the result. Because it doesn’t rely on heavy dependencies, it can be easily included in small scripts or bigger projects alike. -

EJS
Embedded JavaScript templates for node
EJS is a templating engine for JavaScript/Node.js that allows developers to embed plain JavaScript code into HTML markup. The idea is to avoid introducing a separate DSL for templating and instead use familiar JavaScript logic inside template tags to generate dynamic content. You write templates using <% %> scriptlet tags, <%= %> for output, and you can include other templates, pass data, and control flow with loops and conditionals. It’s fast because it compiles templates to JavaScript functions and caches them by default, so subsequent rendering is efficient. EJS supports both server-side render (in Node/Express) and client-side use in the browser, making it versatile for universal apps. Because you’re using raw JS, debugging is simple—the errors are standard JS stack traces with template line numbers included. While it doesn’t impose a rigid structure (you’re free to organize templates however you like), it works reliably and is simple to adopt. -

A JavaScript library that makes working with the HTML5 Canvas element easy. Useful for creating games, generative art, and other highly graphical experiences. EaselJS provides straight forward solutions for working with rich graphics and interactivity with HTML5 Canvas. It provides an API that is familiar to Adobe Animate developers, but embraces JavaScript sensibilities. It consists of a full, hierarchical display list, a core interaction model, and helper classes to make working with Canvas much easier. Added drawPolygon(), pg() and Polygon() Added commands for drawing a polygon from an array of point arrays [[x,y],[x,y],etc] with tiny API of pg as dp is already taken for polystar. -

Element
A Vue.js 2.0 UI Toolkit for Web
Element is a component library based on Vue.js 2.0 that can be used by developers, designers and product managers to build products that are logically sound, well-structured and easy to use. Element uses BEM-styled CSS so you can easily change styles when you want to. There are four ways you can change style variables. You can use the online theme roller to customize design tokens and preview new themes in real-time. You can also use the theme preview website (for changing the theme color only), update SCSS variables, or use the CLI theme tool. You can also import your own custom themes. -

Emoji Mart
One component to pick them all
Data required for the picker to work has been completely decoupled from the library. That gives developers the flexibility to better control their app bundle size and let them choose how and when this data is loaded. Callback when the Add custom emoji button is clicked. The button will only be displayed if this callback is provided. It is displayed when search returns no results. You can use custom emojis by providing an array of categories and their emojis. Emojis also support multiple skin tones and can be GIFs or SVGs. You can use custom category icons by providing an object with the category name as key and the icon as value. Currently supported formats are svg string and src. First, you need to make sure data has been initialized. You need to call this only once per page load. Note that if you call init like this, you don’t necessarily need to include data in your Picker props. It doesn’t hurt either, it will noop. -

Emoji-Log
An Emoji Git commit log messages spec standard
After building hundreds of open source software I've ended up inventing a git commit log standard called EMOJI-LOG that helps me understand a project's history with a less cognitive load just by looking at the git log. I like emoji. I like ’em a lot. Programming, code, geeks/nerds, open-source, all of that is inherently dull and sometimes boring. Emoji (which is, in fact, the plural of emoji) helps me add colors and emotions to the mix. Nothing wrong if you want to attach feelings to this 2D flat text-based world of code. I found out that instead of memorizing hundreds of emoji it's better to keep the categories small and general. -

End-To-End
End-To-End is a crypto library to encrypt, decrypt, digital sign
End-to-End was a client-side encryption project that prototyped OpenPGP-compatible, end-to-end encrypted messaging in the browser. The idea was to move cryptographic operations entirely to the user’s machine—key generation, encryption, and signature—so messages remain unreadable to intermediaries. It packaged a JavaScript crypto library, UI elements, and a browser extension workflow that could integrate with webmail-style UIs without server changes. The codebase emphasized careful key handling, usability experiments around key discovery and verification, and mitigations against common web threats like XSS. While the project ultimately transitioned into successor efforts, it helped push discussions about practical E2EE in mainstream web apps and the ergonomics of PGP-style workflows. Security researchers and product teams used it as a design reference for client-side cryptography and the trade-offs of operating inside a hostile web page. -

Eris
A NodeJS Discord library
A Node.js wrapper for interfacing with Discord. You will need NodeJS 10.4+. If you need voice support you will also need Python 2.7 and a C++ compiler. Create a directory for your bot, and change to that directory in your command line. If you want to be more updated (at the expense of stability), you can install the beta builds instead. Eris supports a few optional libraries that could potentially improve bot performance but may require additional dependencies. If you want Eris to use any of these packages, install them in the same directory as Eris, and Eris will automatically use them. You can find more examples on the GitHub repo. The rest of the docs will help you with using the various functions of the library. Have fun! -

Exifr
The fastest and most versatile JS EXIF reading library
Exifr is a fast and very versatile JavaScript EXIF reading library that works everywhere, parses everything and handles just about anything you throw at it. It can handle any input: buffers, url, <img> tag and more; .jpg, .tif, and .heic files; and TIFF (EXIF, GPS, etc.), XMP, ICC, IPTC, JFIF segments. It skips parsing tags you don’t need, and reads only the first few bytes. There’s no need to read the whole file to see if there’s an EXIF file in it, or extract all the data when you just need a few tags. Instead of reading byte by byte from start to finish, Exifr jumps through the file structure from pointer to pointer, making it extremely fast and efficient! -
