cocoyaxi
A go-style coroutine library in C++11 and more
cocoyaxi (co for short), is an elegant and efficient cross-platform C++ base library. It contains a series of high-quality base components, such as a go-style coroutine, coroutine-based network programming framework, command line, and config file parser, high-performance log library, unit testing framework, JSON library, etc. co has implemented a go-style coroutine, which has the following features. Multi-thread scheduling, the default number of threads is the number of system CPU cores. Shared stack, coroutines in the same thread share several stacks (the default size is 1MB), and the memory usage is low. Simple test on Linux shows that 10 millions of coroutines only take 2.8G of memory (for reference only). There is a flat relationship between coroutines, and new coroutines can be created from anywhere (including in coroutines). Support system API hook (Windows/Linux/Mac), you can directly use third-party network library in coroutine. -

dockview
Zero dependency docking layout manager supporting tabs
dockview is a zero-dependency docking layout manager written in TypeScript that enables developers to create highly dynamic, IDE-like interfaces with draggable panels, tabs, and resizable layouts. It supports multiple layout paradigms, including split views, grid layouts, and dockable panels, allowing complex UI arrangements similar to tools like Visual Studio Code. The library is framework-agnostic at its core, with official bindings for React, Vue, and Angular, as well as support for vanilla TypeScript. Dockview includes advanced features such as floating panels, popout windows, and persistent layout serialization, enabling users to save and restore custom workspace configurations. Its architecture emphasizes performance and flexibility, providing a comprehensive API for programmatic control over layout behavior. The system also supports theming and customization through CSS variables, allowing seamless integration into different design systems. -

env
A simple and zero-dependencies library to parse environment variables
Parse environment variables to structs in Go. In Go, it’s dead simple to get the value from an environment variable. If you have a type that is not supported out of the box by the lib, you are able to use (or define) and pass custom parsers (and their associated reflect.Type) to the env.ParseWithFuncs() function. Env supports by default anything that implements the TextUnmarshaler interface. That includes things like time.Time for example. The upside is that depending on the format you need, you don't need to change anything. The downside is that if you do need time in another format, you'll need to create your own type. By default, slice types will split the environment value on ,; you can change this behavior by setting the envSeparator tag. If you set the envExpand tag, environment variables (either in ${var} or $var format) in the string will be replaced according with the actual value of the variable. -

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. -

lua-resty-openidc
OpenID Connect Relying Party and OAuth 2.0 Resource Server
lua-resty-openidc is a library for NGINX implementing the OpenID Connect Relying Party (RP) and/or the OAuth 2.0 Resource Server (RS) functionality. When used as an OpenID Connect Relying Party it authenticates users against an OpenID Connect Provider using OpenID Connect Discovery and the Basic Client Profile (i.e. the Authorization Code flow). When used as an OAuth 2.0 Resource Server it can validate OAuth 2.0 Bearer Access Tokens against an Authorization Server or, in case a JSON Web Token is used for an Access Token, verification can happen against a pre-configured secret/key. It maintains sessions for authenticated users by leveraging lua-resty-session thus offering a configurable choice between storing the session state in a client-side browser cookie or use in of the server-side storage mechanisms shared-memory|memcache|redis. -

magic-string
Manipulate strings like a wizard
magic-string is a small JavaScript utility for editing strings while preserving accurate source maps. It is designed for compilers, bundlers, preprocessors, and code transformation tools that need to rewrite source code safely. The library lets developers overwrite, append, prepend, remove, move, and slice sections of text without losing track of where transformed content came from. This makes it especially useful when generated output still needs to map back to the original source for debugging. Magic String works in both Node.js and browser environments. Its main value is making code manipulation precise, fast, and source-map-friendly for build tools and language tooling. -

nghttp2
HTTP/2 C Library and tools
nghttp2 is an implementation of HTTP/2 and its header compression algorithm HPACK in C. The framing layer of HTTP/2 is implemented as a form of reusable C library. On top of that, we have implemented HTTP/2 client, server and proxy. We have also developed a load test and benchmarking tool for HTTP/2. We have participated in httpbis working group since HTTP/2 draft-04, which is the first implementation draft. Since then we have updated nghttp2 library constantly to the latest specification and nghttp2 is now one of the most mature HTTP/2 implementations. HTTP/2 utilizes header compression method called HPACK. We offer HPACK encoder and decoder are available as public API. nghttp2 library itself is a bit low-level. The experimental high-level C++ API is also available. We have Python binding of this library, but we have not covered everything yet. -
