pgsodium
Modern cryptography for PostgreSQL using libsodium
pgsodium is an encryption library extension for PostgreSQL using the libsodium library for high-level cryptographic algorithms. pgsodium can be used a straight interface to libsodium, but it can also use a powerful feature called Server Key Management where pgsodium loads an external secret key into memory that is never accessible to SQL. This inaccessible root key can then be used to derive sub-keys and keypairs by key id. This id (type bigint) can then be stored instead of the derived key. -

pixelmatch
The smallest, simplest JavaScript pixel-level image comparison library
The smallest, simplest and fastest JavaScript pixel-level image comparison library, originally created to compare screenshots in tests. Features accurate anti-aliased pixels detection and perceptual color difference metrics. Inspired by Resemble.js and Blink-diff. Unlike these libraries, pixelmatch is around 150 lines of code, has no dependencies, and works on raw typed arrays of image data, so it's blazing fast and can be used in any environment (Node or browsers). Compares two images, writes the output diff and returns the number of mismatched pixels. -

plotly.js
JavaScript charting library behind Plotly and Dash
Plotly JavaScript Open Source Graphing Library. Built on top of d3.js and stack.gl, Plotly.js is a high-level, declarative charting library. plotly.js ships with over 40 chart types, including 3D charts, statistical graphs, and SVG maps. plotly.js is free and open source and you can view the source, report issues or contribute on GitHub. For plotly.js to build with Webpack you will need to install ify-loader@v1.1.0+ and add it to your webpack.config.json. This adds Browserify transform compatibility to Webpack which is necessary for some plotly.js dependencies. When users hover over a figure generated with plotly.js, a modebar appears in the top-right of the figure. This presents users with several options for interacting with the figure.

react-chat-elements
Reactjs chat elements chat UI, react chat components
react-chat-elements is a React-based UI library specifically designed for building chat and messaging interfaces with minimal effort. It provides a set of prebuilt components such as message bubbles, chat lists, input fields, avatars, and typing indicators, all styled to resemble modern messaging applications. The library is intended to accelerate development by offering ready-to-use elements that handle common chat interface requirements without requiring developers to design them from scratch. It supports customization through props and styling options, allowing developers to adapt the components to match their application’s branding and behavior. The components are designed to be modular and composable, enabling developers to build complex chat interfaces by combining smaller building blocks. It is particularly useful for applications that include messaging features, customer support chats, or real-time communication tools. -

react-error-boundary
Simple reusable React error boundary component
react-error-boundary is a tiny, well-tested utility that makes React’s error boundaries practical and ergonomic for everyday apps. It wraps React’s error-handling primitives in a single <ErrorBoundary> component with a predictable API for rendering fallbacks when descendant components throw during render, lifecycle, or event handlers. The library emphasizes recovery, not just failure: you can reset the error state programmatically or when certain “reset keys” change, returning the subtree to a healthy state without a full page refresh. It supports both declarative fallbacks (elements) and a render-prop approach so you can tailor the UI to the error and provide retry buttons or diagnostics. Callbacks make it easy to log errors to your own telemetry, show toasts, or trigger side effects when boundaries trip or reset. A companion useErrorHandler hook lets you re-throw async errors from hooks or event handlers into the nearest boundary, unifying error flows across component styles. -

react-widgets is a set of customizable and accessible UI components built for React applications, focusing on form inputs and interactive elements. It provides components such as dropdowns, date pickers, comboboxes, and multiselect inputs, designed to handle complex user interactions with ease. The library emphasizes accessibility, ensuring compatibility with keyboard navigation and screen readers. It also supports internationalization, allowing developers to adapt components for different locales and languages. react-widgets is highly customizable, enabling developers to style and configure components according to their application’s design system. It integrates seamlessly into modern React workflows and supports controlled and uncontrolled component patterns. Overall, react-widgets offers a robust toolkit for building user-friendly and accessible form interfaces. -

reproc
A cross-platform (C99/C++11) process library
reproc (Redirected Process) is a cross-platform C/C++ library that simplifies starting, stopping and communicating with external programs. The main use case is executing command line applications directly from C or C++ code and retrieving their output. reproc consists out of two libraries: reproc and reproc++. reproc is a C99 library that contains the actual code for working with external programs. reproc++ depends on reproc and adapts its API to an idiomatic C++11 API. It also adds a few extras that simplify working with external programs from C++. -

spartan
Cutting-edge tools powering Angular full-stack development
spartan is a modern, experimental full-stack toolkit designed to enhance Angular development by combining a flexible UI component system with a broader application stack. It is structured as a monorepo that includes both a UI library and a full-stack solution, enabling developers to build complete applications with consistent tooling and design patterns. One of its defining characteristics is its inspiration from libraries like shadcn/ui, emphasizing ownership of code rather than heavy abstraction, which allows developers to fully customize and extend their components. The UI layer is built on accessible, unstyled primitives that can be enhanced with styled layers, giving teams control over both accessibility and visual design without being locked into a rigid theme. Spartan integrates well with modern Angular tooling such as Nx and Tailwind CSS, making it suitable for scalable, enterprise-level projects. -

tapir
Declarative, type-safe web endpoints library
Declarative, type-safe web endpoints library. With tapir, you can describe HTTP API endpoints as immutable Scala values. Each endpoint can contain a number of input and output parameters. Compile-time guarantees, develop-time completions, read-time information. Separate the shape of the endpoint (the "what"), from the server logic (the "how"). Generate documentation from endpoint descriptions. Leverage the metadata to report rich metrics and tracing information. Re-use common endpoint definitions, as well as individual inputs/outputs. Library, not a framework, integrates with your stack. Is your company already using tapir? We're continually expanding the "adopters" section in the documentation; the more the merrier! It would be great to feature your company's logo, but in order to do that, we'll need to write permission to avoid any legal misunderstandings. -

timeago
The original jQuery plugin that makes it easy to support automatically
Timeago is a jQuery plugin that makes it easy to support automatically updating fuzzy timestamps (e.g. "4 minutes ago" or "about 1 day ago") from ISO 8601 formatted dates and times embedded in your HTML (à la microformats). -

uCrop
Image cropping library for Android
We develop lots of different Android apps at Yalantis, and our experience shows that almost every application we deal with needs image cropping functionality. Image cropping can be used for various purposes, from ordinary adjustment of user profile images to more complex features that involve aspect ratio cropping and flexible image transformations. Since we want to provide all our customers with the best set of tools for image editing functionality, we decided to create uCrop, an image cropping library for Android. You might be wondering why we couldn’t just use one of the existing solutions for image cropping for Android. After all, you can find lots of them on Github and on the Android Arsenal. But here is the thing, none of these solutions could satisfy our requirements. Let’s take a quick look at the most popular open-source image cropping libraries and explain why they don’t quite fit the bill. -
