It provides easy to use event-driven interface that allows to implement network protocols or scalable network applications with little effort. Mongoose helps developers to manage the complexity of network programming and let them concentrate on the logic, saving time and money. Mongoose has built-in support for several protocols, like HTTP, Websocket, MQTT, mDNS. Example applications include Websocket-based chat server, JSON-RPC server, database server with RESTful API, MQTT broker, netcat with SSL and hexdump, Raspberry PI camera video feed + led control, and more. Mongoose is ideal for the embedded environments, it has been designed as an open source platform for connecting devices and bringing them online.
