go-github
Go library for accessing the GitHub API
go-github is a Go client library for accessing the GitHub API v3. Currently, go-github requires Go version 1.13 or greater. go-github tracks Go's version support policy. We do our best not to break older versions of Go if we don't have to, but due to tooling constraints, we don't always test older versions. If you're interested in using the GraphQL API v4, the recommended library is shurcooL/githubv4. go-github is compatible with modern Go releases in module mode. Resolve and add the package to the current development module, along with its dependencies. Alternatively the same can be achieved if you use import in a package. Construct a new GitHub client, then use the various services on the client to access different parts of the GitHub API. Some API methods have optional parameters that can be passed. Using the context package, one can easily pass cancelation signals and deadlines to various services of the client for handling a request. -

go-toml
Go library for the TOML file format
Go library for the TOML format. This library supports TOML v1.0.0. Full API, examples, and implementation notes are available in the Go documentation. As much as possible, this library is designed to behave similarly as the standard library's encoding/json. While go-toml favors usability, it is written with performance in mind. Most operations should not be shockingly slow. Decoder can be set to "strict mode", which makes it error when some parts of the TOML document was not present in the target structure. This is a great way to check for typos. When most decoding errors occur, go-toml returns DecodeError), which contains a human readable contextualized version of the error. TOML supports native local date/times. It allows to represent a given date, time, or date-time without relation to a timezone or offset. To support this use-case, go-toml provides LocalDate, LocalTime, and LocalDateTime. -

hyper for Rust
An HTTP library for Rust
hyper is a fast HTTP implementation written in and for Rust. A Client for talking to web services. A Server for building those web services. Blazing fast thanks to Rust. High concurrency with non-blocking sockets. HTTP/1 and HTTP/2 support. hyper is a relatively low-level library, meant to be a building block for libraries and applications. If you are looking for a convenient HTTP client, then you may wish to consider reqwest. If you are looking for a convenient HTTP server, then you may wish to consider warp. Both are built on top of this library. A Service lets you define how to respond to incoming requests. While it is possible to implement the trait directly, there are a few patterns that are common when using Hyper. We’ve included some helpers for when these patterns fit our needs. An echo server will listen for incoming connections and send back the request body as the response body on POST requests. -

jCasbin
An authorization library that supports access control models
An authorization library that supports access control models like ACL, RBAC, ABAC for Golang, Java, C/C++, Node.js, Javascript, PHP, Laravel, Python, .NET (C#), Delphi, Rust, Ruby, Swift (Objective-C), Lua (OpenResty), Dart (Flutter) and Elixir. In Casbin, an access control model is abstracted into a CONF file based on the PERM metamodel (Policy, Effect, Request, Matchers). So switching or upgrading the authorization mechanism for a project is just as simple as modifying a configuration. Besides memory and file, Casbin policy can be stored into lots of places. Currently, dozens of databases are supported, from MySQL, Postgres, Oracle to MongoDB, Redis, Cassandra, AWS S3. jCasbin is a powerful and efficient open-source access control library for Java projects. It provides support for enforcing authorization based on various access control models. -

koanf
Simple, lightweight, extensible, configuration management library
koanf (pronounced conf; a play on the Japanese Koan) is a library for reading configurations from different sources in different formats in Go applications. It is a cleaner, lighter alternative to spf13/viper with better abstractions and extensibility, and fewer dependencies. koanf comes with built-in support for reading configuration from files, command line flags, and environment variables, and can parse JSON, YAML, TOML, and Hashicorp HCL. Any external dependencies are detached from the core into sub-packages, so only the ones that are explicitly referenced get compiled into an application. Once loaded into koanf, configuration are values queried by a delimited key path syntax. eg: app.server.port. Any delimiter can be chosen. Configuration from multiple sources can be loaded and merged into a koanf instance, for example, load from a file first and override certain values with flags from the command line. -

libevent
Event notification library
The libevent API provides a mechanism to execute a callback function when a specific event occurs on a file descriptor or after a timeout has been reached. Furthermore, libevent also support callbacks due to signals or regular timeouts. libevent is meant to replace the event loop found in event driven network servers. An application just needs to call event_dispatch() and then add or remove events dynamically without having to change the event loop. The internal event mechanism is completely independent of the exposed event API, and a simple update of libevent can provide new functionality without having to redesign the applications. As a result, Libevent allows for portable application development and provides the most scalable event notification mechanism available on an operating system. Libevent can also be used for multi-threaded applications, either by isolating each event_base so that only a single thread accesses it, or by locked access to a single shared event_base. -

libphonenumber
Library for parsing and validating international phone numbers
Google's common Java, C++ and JavaScript library for parsing, formatting, and validating international phone numbers. The Java version is optimized for running on smartphones, and is used by the Android framework since 4.0 (Ice Cream Sandwich). libphonenumber gets the type of the number based on the number itself; able to distinguish Fixed-line, Mobile, Toll-free, Premium Rate, Shared Cost, VoIP, Personal Numbers, UAN, Pager, and Voicemail (whenever feasible). Provides valid example numbers for all countries/regions, with the option of specifying which type of example phone number is needed. Quickly guesses whether a number is a possible phone number by using only the length information, much faster than a full validation. To include the Java code in your application, either integrate with Maven (see wiki) or download the latest jars from the Maven repository. -

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. -
17
pytz
Python historical timezone library and database
pytz is a Python library that brings the IANA/Olson timezone database into the Python runtime, enabling accurate, cross-platform timezone calculations for all the world’s timezones. It addresses a major limitation of Python’s built-in datetime.tzinfo by providing consistent support for daylight-saving transitions, historical offset changes, and ambiguous times (such as the end of DST). With pytz, developers can convert naïve datetime objects into timezone-aware ones, shift between timezones, and safely perform arithmetic across DST boundaries with methods like localize() and normalize(). Although Python 3.9 and newer include better built-in timezone support (via zoneinfo and external packages like tzdata), pytz remains widely used—especially in legacy codebases or in environments where backward compatibility matters. -

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. -

uvloop
Ultra fast asyncio event loop
uvloop is an ultra-fast, drop-in replacement of the built-in asyncio event loop. Together with asyncio and the power of async/await in Python 3.5, uvloop makes it easier than ever to write high-performance Python networking code. uvloop makes asyncio incredibly fast-- 2 to 4 times faster than nodejs, or any other Python asynchronous framework. The performance of asyncio when it is uvloop-based is almost comparable to that of Go programs. uvloop is written in Cython and is built on top of libuv, a high performance, fast and stable multiplatform asynchronous I/O library used by nodejs.
