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. -

Earth Engine API
Python and JavaScript bindings for calling the Earth Engine API
The Earth Engine API provides Python and JavaScript client libraries for Google Earth Engine, a planetary-scale geospatial analysis platform. With it, users compose lazy, server-side computations over massive catalogs of satellite imagery and vector datasets without handling raw files locally. The API exposes functional operators for map algebra, reducers, joins, and machine learning that scale transparently on Earth Engine’s backend. Developers authenticate once, work interactively in notebooks or the Code Editor, and export results to Cloud Storage, Drive, or asset collections. Visualization helpers render tiled layers and charts so analysts can iterate quickly on workflows like land-cover mapping, change detection, or time-series analysis. By combining petabyte-scale data with concise functional transforms, the API turns complex remote-sensing pipelines into reproducible scripts that are easy to share. -

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! -

Facebook-style lightbox, built in jQuery
Facebox is a jQuery-based lightbox plugin designed to display content in a modal overlay on top of a webpage. It allows developers to present images, HTML content, or remote data in a visually appealing popup without navigating away from the current page. The plugin is inspired by early lightbox implementations and focuses on simplicity and ease of integration into existing web projects. It provides a clean user experience by dimming the background and highlighting the modal content, drawing attention to the displayed information. Facebox supports loading content via AJAX, making it useful for dynamic applications where content is fetched on demand. It also includes basic styling and animation effects to enhance usability and presentation. -
