MythCore
Myth Framework Core Libraries (part of MythSDP)
MythCore is a PHP framework that allows the developer to use a C# .NET like object oriented programming approach. It provides the essential classes that the MythSDP platform and the MythFramework builds upon. The goal is to create a library that enables the programmer to use a fully object oriented approach that has the "feel" of .NET and Java programming. Our main goal is ease of use and rapid application development. However, performance and small-footprint are some of the main design goals as well. -

NG6
An AngularJS Starter repo for AngularJS + ES6 + Webpack
NG6 is a starter project for building single-page applications with AngularJS 1.x, modern ES6 JavaScript, and Webpack as the module bundler. It provides a minimal but opinionated boilerplate that shows best practices for structuring a scalable Angular app using a fully componentized file layout. The project wires together Webpack and Babel to handle ES6 transpilation, asset bundling, and hot reloading during development. Gulp is used as an orchestrator to run Webpack, start a development server, and generate Angular boilerplate via tasks. The repository also includes a complete testing setup using Karma, Mocha, Chai, and Webpack so tests run through the same pipeline as application code. Styles are handled via SASS (node-sass), with each component encouraged to bundle its own styles, templates, and tests for strong locality. Overall, NG6-starter is designed as a “de facto” reference for developers who want to learn and adopt a modern workflow. -

NanoNeuron
NanoNeuron is 7 simple JavaScript functions
Nano-Neuron is a didactic project that reduces the idea of a neuron to a handful of tiny JavaScript functions so learners can see “learning” in action without heavy frameworks. It demonstrates how a scalar input can be linearly transformed with a weight and bias, then adjusted via gradient updates to fit a simple mapping such as Celsius-to-Fahrenheit conversion. The code emphasizes readability over performance, inviting you to step through calculations and watch parameters converge. Because every concept is expressed in a few lines, it’s easy to tinker—change learning rates, swap cost functions, or visualize error curves. The repository bridges the gap between formulae and intuition by making each update transparent and observable. It’s ideal for absolute beginners who want to internalize core ideas before moving on to multi-layer networks and libraries. -

NativeUI
The most crossbrowser web UI library that uses native browser elements
NativeUI is a CSS and JavaScript library that adheres to the KISS principle and focuses on utilizing standard features provided by browsers, which are most optimized for each specific platform, and therefore provide the best performance and user experience. The library ensures cross-browser behavior and styling of built-in browser elements of user interface and text formatting, adding commonly used user interface elements such as modal windows, image viewer, menus, tabs, form messages, etc. It also contains some useful JavaScript functions for development, such as request() and getFormData(). You can see the demo here: https://nativeui.sourceforge.io/ -

Nightmare
A high-level browser automation library
Nightmare is a high-level browser automation library from Segment. The goal is to expose a few simple methods that mimic user actions (like goto, type and click), with an API that feels synchronous for each block of scripting, rather than deeply nested callbacks. It was originally designed for automating tasks across sites that don't have APIs, but is most often used for UI testing and crawling. Segment started with an open source project. Since then, we’ve open sourced hundreds of our repos. We want to continue supporting the community by publishing our code and other developers’ awesome open source projects. We use these open source projects as the foundations of our infrastructure to handle billions of API calls per day and to allow us to rapidly build and test code on the client. -

Nock
HTTP server mocking and expectations library for Node.js
HTTP server mocking and expectations library for Node.js. Nock can be used to test modules that perform HTTP requests in isolation. For instance, if a module performs HTTP requests to a CouchDB server or makes HTTP requests to the Amazon API, you can test that module in isolation. Nock works by overriding Node's http.request function. Also, it overrides http.ClientRequest too to cover for modules that use it directly. -

Node.js Testing Best Practices
Beyond the basics of Node.js testing
This repository narrows the testing lens to Node.js backends, focusing on the challenges of servers, microservices, and cloud-native deployments. It covers API testing, contract testing, and persistence-layer strategies that avoid coupling tests to fragile implementation details. The material explains how to structure tests around process boundaries—HTTP, queues, cron jobs—while keeping fast feedback cycles through selective integration tests and reliable test doubles. It dives into topics like test containers, ephemeral databases, and idempotent fixtures to ensure deterministic runs in CI. Observability is treated as part of testing: logs, metrics, and tracing make failures diagnosable instead of mysterious. By aligning tests with service responsibilities instead of internal modules, the guide helps teams produce suites that reflect real production behavior. -

NomeJS
Nome is a JavaScript library for location driven sites
Nome (pronounced know me) is a JavaScript library that leverages the power of HTML5 geolocation and location data. This type of data isn't normally exposed within a user session without signing up to multiple services and installing many large database files locally. Nome gives direct access to location and weather data from an exposed JavaScript API allowing you to create context driven websites that deliver information relevant to your audience. With clever thinking nome has the potential to change the way you deliver content to your audience. A bar could show offers for cool drinks if the temperature rose above 25°c; A shop could entice with targeted offers to customers right outside their door. With nome giving access to more information than is currently offered from a standard browser session, you or your clients could be engaging customers in a new way. -

Numeral.js
A javascript library for formatting and manipulating numbers
You can use Numerals in the browser and in Node.js. Create an instance of a numeral, Numeral takes numbers or strings that it trys to convert into a number. Numbers can be formatted to look like currency, percentages, times, or even plain old numbers with decimal places, thousands, and abbreviations. And you can always create a custom format. Set a default format so you can use .format() without a string. The default format to '0,0'. Set a custom output when formatting numerals with a value of 0 or null. Adding your own custom formats is as easy as adding a locale. Numeral.js, while less complex, was inspired by and heavily borrowed from Moment.js Formats now exist in their own files and act more or less as plugins. Check out the bytes format for an example of how to create one. When naming locale files use the ISO 639-1 language codes supplemented by ISO 3166-1 country codes when necessary. -
