Utilizing response encoders and decoders

Flask framework supports the built Python json module by default. The built-in encoders, dumps(), and loads(), are found in the flask.json module. In the Managing the requests and responses section, the add_login() endpoint function uses the flask.json.loads() to de-serialize and transform the request.data into a JSONable dictionary. Meanwhile, the flask.json.dumps() provided the Response class with a JSONable object for some JSON response output, as previously highlighted in the list_all_login() endpoint.

But any application can override these default encoding and decoding processes to solve some custom requirements. Customizing an appropriate JSON provider by sub-classing Flask’s JSONProvider, found in the flask.json.provider, can allow the overriding of these JSON processes. The following is a custom implementation of a JSONProvider with some modifications to the dumps() and loads() algorithms:
