Spark Kotlin
Spark-kotlin is a lightweight web framework for the Java Virtual Machine that provides a domain-specific language for building server-side applications. It functions as an HTTP request router, allowing developers to map URL patterns and request methods to functional handlers to process web traffic.
The framework utilizes a static method-based syntax to configure the embedded server runtime and manage network connections. It supports real-time bidirectional communication through an event-driven lifecycle for web sockets, enabling the definition of handlers for connection events and incoming data streams.
Beyond core routing, the framework provides capabilities for managing server settings, such as port configuration and thread pool allocation, as well as tools for redirecting web traffic. It is designed for the development of web services and microservices by translating idiomatic language features into underlying server operations.
Features
