Spry JSON middleware and request/response extension, used to convert request body to JSON object or set response body to JSON object.

Add dependencies in pubspec.yaml:

dependencies:
  spry_json: any

Or install via command line:

$ dart pub add spry_json

The Spry JSON extension is zero-configuration and only needs to be imported to use:

import 'package:spry/spry.dart';
import 'package:spry_json/spry_json.dart';

handler(Context context) {
   context.response.json({"foo": "bar"});
}

When you need it, you can get the requested JSON object via context.request.json():

handler(Context context) {
   final json = context.request.json();
  
   //...
}

To return a JSON object, you can use the context.response.json() method:

handler(Context context) {
   context.response.json({"foo": "bar"});
}

It will automatically set the Content-Type to application/json.

Spry JSON is zero configuration, but you can create a JSON configuration middleware through SpryJson object:

import 'package:spry_json/spry_json.dart';

final SpryJson json = SpryJson(
   /// options
);

spry.use(json);
