The framework core has two key components: the router and the native API. The router component is responsible for processing HTTP and WebSocket messages. Neutralinojs typically serve all web resources via HTTP like a normal HTTP web server. The Neutralinojs native API communication protocol uses the WebSocket messaging protocol.
The router serves web resources and executes native API functions according to the incoming requests from the web context.
Because of this flexibility, you can write extensions with any programming language and connect to the framework core with authentication details. Even though an extension-less application follows a monolithic pattern, extensions make Neutralinojs applications non-monolithic with the process-based microservices architecture.
