Passport
Simple, unobtrusive authentication for Node.js
Passport is a flexible authentication middleware for Node.js that provides a modular and extensible system for handling user login and identity in web applications. It doesn’t impose specific user model structures or storage strategies but instead offers a unified API driven by “strategies”—small plugins that encapsulate authentication logic for protocols such as local username/password, OAuth, OpenID, SAML, and many others. This design allows developers to plug in only the strategies they need and swap or add new ones without rewriting core application logic, making Passport highly adaptable for diverse authentication requirements. Passport hooks into Express (and similar frameworks) using middleware functions that run during the request lifecycle, simplifying tasks like session management, credential validation, and user serialization. -

PatchMon
Linux Patch Monitoring Automation Platform
PatchMon is a centralized patch monitoring and management platform aimed at simplifying how administrators observe and manage package updates across diverse Linux server environments. It centralizes patch status information from many hosts into a single dashboard where users can view inventories of outdated packages, track repositories per host, and organize machines into logical groups for easier oversight. Agents installed on each server make outbound-only connections to the PatchMon server, improving security by avoiding open inbound ports, while the server side provides role-based access control, user management, and a REST API for integrations. PatchMon also supports a customizable dashboard, detailed per-host metrics, and one-line installers for quick self-hosted deployment, making it suitable for both small clusters and larger fleets. -

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. -

ProgressBar.js
Responsive and slick progress bars
Responsive and slick progress bars with animated SVG paths. Use built-in shapes or create your own paths. Customize the animations as you wish. With ProgressBar.js, it's easy to create responsive and stylish progress bars for the web. Animations perform well even on mobile devices. It provides a few built‑in shapes like Line, Circle and SemiCircle but you can also create custom shaped progress bars with any vector graphic editor. ProgressBar.js is lightweight, MIT licensed and supports all major browsers including IE9+. A simple code example of creating a Line shaped progress bar and animating it from 0% to 100%. ProgressBar.js uses shifty tweening library to animate path drawing. So in other words, animation is done with JavaScript using requestAnimationFrame. Animating with JS gives more control over the animation and is supported across major browsers. For example IE does not support animating SVG properties with CSS transitions. -

If you want to create your own specific chart or image crop and rotate widget, for example, you can achieve it simply and easily with this library. Raphaël ['ræfeɪəl] uses the SVG W3C Recommendation and VML as a base for creating graphics. This means every graphical object you create is also a DOM object, so you can attach JavaScript event handlers or modify them later. Raphaël’s goal is to provide an adapter that will make drawing vector art compatible cross-browser and easy. Raphaël currently supports Firefox 3.0+, Safari 3.0+, Chrome 5.0+, Opera 9.5+ and Internet Explorer 6.0+. Versions will be released as we gather and test new PRs. As there are a lot of browsers being supported it might take a while to accept a PR, we will use the feedback from other users too. You can use the raphaelTest.html to try things, you need to start a server in the root dir to start testing things there. -

Redux Thunk
Thunk middleware for Redux
Redux Thunk is Thunk middleware for Redux. With basic Redux, only simple synchronous updates can be done by dispatching an action. By adding middleware, you extend the Redux store's abilities, enabling you to write async logic that interacts with the store. A thunk is a function that wraps an expression in order to delay its evaluation. Redux Thunk middleware allows you to write action creators that, rather than return an action will return a function instead. If you want to delay the dispatch of an action, or to dispatch only after meeting a certain condition, then the thunk can be used. Thunks are ideal middleware for a number of cases, in particular for basic Redux side effects logic, complex synchronous logic that must access the store, and simple async logic like AJAX requests. -

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. -

In 2016, we rebuilt Screwdriver from scratch in open source with our best coding practices and CICD goals in mind. Screwdriver is executor and SCM-agnostic, meaning you can choose whichever plugin better suits your need or build your own. It's completely free and open-source, and our team is actively maintaining the code. Screwdriver is a self-contained, pluggable service to help you build, test, and continuously deliver software using the latest containerization technologies. We support an expanding list of source code services, execution engines, and databases so Screwdriver can work in your ecosystem. -
