About Datastar

Datastar is a lightweight hypermedia framework that enables developers to build reactive web applications using simple HTML attributes (`data-*`) and server-side logic. It eliminates the need for complex JavaScript frameworks while providing real-time capabilities, reactive frontend, and other features out of the box. **Official Links:** - 🌐 [Official Website](https://data-star.dev) - 📚 [GitHub Repository](https://github.com/starfederation/datastar/) - 🏢 [GitHub Organization](https://github.com/starfederation) - Official SDKs for Python, Java, PHP, .NET, Clojure, Rust, Kotlin, Go, Ruby, and more - 📖 [Documentation](https://data-star.dev/guide)
