Playwright for .NET
.NET version of the Playwright testing and automation library
Playwright for .NET is the official language port of Playwright, the library to automate Chromium, Firefox and WebKit with a single API. Playwright is built to enable cross-browser web automation that is ever-green, capable, reliable and fast. Cross-browser. Playwright supports all modern rendering engines including Chromium, WebKit, and Firefox. Cross-platform. Test on Windows, Linux, and macOS, locally or on CI, headless or headed. Cross-language. Use the Playwright API in TypeScript, JavaScript, Python, .NET, Java. Test Mobile Web. Native mobile emulation of Google Chrome for Android and Mobile Safari. The same rendering engine works on your Desktop and in the Cloud. Auto-wait. Playwright waits for elements to be actionable prior to performing actions. It also has a rich set of introspection events. The combination of the two eliminates the need for artificial timeouts - the primary cause of flaky tests. -

ProShop eCommerce Platform
Shopping cart built with MERN & Redux
ProShop is a full-stack e-commerce teaching project that demonstrates how to build a production-style store with the MERN stack. The backend uses Node.js and Express to expose RESTful endpoints for products, users, orders, and payments, with MongoDB handling persistence and indexing. Authentication uses JWT and protected routes, while role-based guards separate shopper and admin flows such as product management and order fulfillment. The React frontend implements routing, global state, cart logic, checkout steps, reviews, search, and pagination so learners see a complete UX from browse to purchase. The codebase also walks through image uploads, third-party payment integration, and environment configuration suited for deployment. It’s designed as a reference you can extend—swap UI libraries, add coupons, connect different gateways, or move to a containerized deployment—without losing the core architecture. -

Protractor
E2E test framework for Angular apps
Protractor is an end-to-end test framework for Angular and AngularJS applications. Protractor runs tests against your application running in a real browser, interacting with it as a user would. Protractor is built on top of WebDriverJS, which uses native events and browser-specific drivers to interact with your application as a user would. Protractor supports Angular-specific locator strategies, which allows you to test Angular-specific elements without any setup effort on your part. You no longer need to add waits and sleeps to your test. Protractor can automatically execute the next step in your test the moment the webpage finishes pending tasks, so you don’t have to worry about waiting for your test and webpage to sync. Protractor needs two files to run, a spec file and a configuration file. Open a new command line or terminal window and create a clean folder for testing. -

Ramme
Unofficial Instagram Desktop App
Unofficial Instagram Desktop App. The latest version of Ramme for macOS, Linux and Windows is available. macOS 10.9+, Windows 7+ & Linux are supported. Although technically it is possible to access Instagram from the desktop of the PC thanks to its web version , it is not the same as using the app. The design is not the same, the navigation is also different and in general it does not provide the same user experience as the mobile app. Ramme, (name whose meaning in Danish is " photo frame ") replicates the design of the mobile app in detail, in an agile and easy-to-use interface (because you already know it very well). Of course, do not expect extra functions or added options beyond the basic ones of the Instagram app itself. Precisely this simplicity and minimalism is one of its strengths. Ramme is a good alternative for those looking to have the same Instagram experience on desktop as on their mobile, and don't want to rely on a web page in the browser. -

React Helmet
A document head manager for React
This reusable React component will manage all of your changes to the document head. Helmet takes plain HTML tags and outputs plain HTML tags. It's dead simple, and React beginner friendly. Helmet 5 is fully backward-compatible with previous Helmet releases, so you can upgrade at any time without fear of breaking changes. We encourage you to update your code to our more semantic API, but please feel free to do so at your own pace. If you are using a prebuilt compilation of your app with webpack in the server be sure to include this in the webpack file so that the same instance of react-helmet is used. Supports all valid head tags: title, base, meta, link, script, noscript, and style tags. It also supports attributes for body, html and title tags. Duplicate head changes are preserved when specified in the same component (support for tags like "apple-touch-icon"). -

React Hot Loader
Tweak React components in real time
React Hot Loader is a plugin that allows React components to be live reloaded without the loss of state. It works with Webpack and other bundlers that support both Hot Module Replacement (HMR) and Babel plugins. HMR allows us to replace modules in-place without restarting the server. Here’s how you can enable it for different bundlers. The easiest and fastest option to use React Hot Loader with Webpack is to use webpack-dev-server with --hot CLI option. If you’re only rendering on the client side but you have to use some custom node server, this is still an easy option. You can simply copy server.js from the official boilerplate into your project. The important part of the configuration is that when you create a new WebpackDevServer, you need to specify hot: true as an option. -

React-Bootstrap
Bootstrap components built with React
React-Bootstrap replaces the Bootstrap JavaScript. Each component has been built from scratch as a true React component, without unneeded dependencies like jQuery. As one of the oldest React libraries, React-Bootstrap has evolved and grown alongside React, making it an excellent choice as your UI foundation. Built with compatibility in mind, we embrace our bootstrap core and strive to be compatible with the world's largest UI ecosystem. By relying entirely on the Bootstrap stylesheet, React-Bootstrap just works with the thousands of Bootstrap themes you already love. The React component model gives us more control over form and function of each component. Each component is implemented with accessibility in mind. The result is a set of accessible-by-default components, over what is possible from plain Bootstrap. -

ReduxCasts
Modern React with Redux
ReduxCasts is a course companion repository for Stephen Grider’s Modern React with Redux material. It contains completed code examples from different parts of the course so learners can inspect working implementations. The repository helps students understand React components, Redux state flow, action creators, reducers, routing, middleware, and related front-end patterns. It is structured as a learning reference, allowing users to review finished examples or compare changes section by section. Since it represents course-era React and Redux practices, it is best used as an educational snapshot rather than a current production architecture recommendation. Its value is in making abstract Redux concepts easier to study through concrete project code. -

Reselect
Selector library for Redux
Simple “selector” library for Redux (and others) inspired by getters in NuclearJS, subscriptions in re-frame and this proposal from speedskater. Selectors can compute derived data, allowing Redux to store the minimal possible state. Selectors are efficient. A selector is not recomputed unless one of its arguments changes. Selectors are composable. They can be used as input to other selectors. Reselect provides a function createSelector for creating memoized selectors. createSelector takes an array of input-selectors and a transform function as its arguments. If the Redux state tree is mutated in a way that causes the value of an input-selector to change, the selector will call its transform function with the values of the input-selectors as arguments and return the result. If the values of the input-selectors are the same as the previous call to the selector, it will return the previously computed value instead of calling the transform function. -

SAN
A fast, portable, flexible JavaScript component framework
Declarative template. HTML conformant template makes it easier for HTML developers. The DOM will be updated accordingly by the view engine upon any data modification. Free yourself from trivial and error-prone DOM APIs. A component is a combination of data, logic and view. Feature blocks, from a single input combination to a whole page, can be built via San components. By modifying the data, the view engine can directly refresh the view area that needs to be changed without any detection and better performance. Optimized for the first screen and output HTML from the server-side. Reverse parse components from existing elements and build bindings. Volume less that 17kb (gzipped), no need to worry about the burden of page downloads. The gospel of patients with volume obsessive. The ESNext Module or AMD can be selected in the project. Of course, if you want to use global variables it is also supported. -

Scalene
High-performance CPU, GPU, and memory profiler for Python
Scalene is a high-performance CPU, GPU and memory profiler for Python that does a number of things that other Python profilers do not and cannot do. It runs orders of magnitude faster than other profilers while delivering far more detailed information. Once Scalene has profiled your program, it will launch a web browser with an interactive user interface (all processing is done locally). Hover over bars to see breakdowns of CPU and memory consumption, and click on underlined column headers to sort the columns. Scalene is fast. It uses sampling instead of instrumentation or relying on Python's tracing facilities. Its overhead is typically no more than 10-20% (and often less). Scalene performs profiling at the line level and per function, pointing to the functions and the specific lines of code responsible for the execution time in your program. Scalene separates out the percentage of memory consumed by Python code vs. native code. -

SlimerJS
A scriptable browser like PhantomJS, based on Firefox
SlimerJS is a scriptable browser. It allows you to manipulate a web page with an external Javascript script: opening a webpage, clicking on links, modifying the content... It is useful to do functional tests, page automation, network monitoring, screen capture etc. It is a tool like PhantomJs, except that it runs Gecko instead of Webkit, and it is headless when using Firefox 56+. It can be used with Firefox 59. Higher version of Firefox is not supported and probably will not be supported in the future, as the development is suspended for now. SlimerJS provides the same API of PhantomJS. The current version of SlimerJS is highly compatible with PhantomJS 2.1. See current release notes in docs/release-notes-*.rst, and read the compatibility table to know the implementation level. The main goal of SlimerJS is to allow to execute all scripts developed for PhantomJS. So you could use tools like CasperJS. In fact, CasperJs 1.1 and higher can be executed with SlimerJS!
