http_parser is a platform-independent package for parsing and serializing various HTTP-related formats. It's designed to be usable on both the browser and the server, and thus avoids referencing any types from dart:io or dart:html. It includes:

• Support for parsing and formatting dates according to HTTP/1.1, the HTTP/1.1 standard.

• A MediaType class that represents an HTTP media type, as used in Accept and Content-Type headers. This class supports both parsing and formatting media types according to HTTP/1.1.

• A WebSocketChannel class that provides a StreamChannel interface for both the client and server sides of the WebSocket protocol independently of any specific server implementation.
