Dart: Scalable Application Development

Receiving data on the web server

In the previous recipe, we made a client app that sends its data to a web server in JSON format. In this recipe, we will make the web server that receives this data step by step, possibly process it, and then send it back to the client. You can find the code in the script server\webserver.dart in the project post_form.
