How to configure Django Rest Framework + React
For dev:
You can run both of them on two different shells. By default, your django rest api will be at 127.0.0.1:8000 and React will at 127.0.0.1:8081. I do not think there will be any issues for the two to communicate via the fetch api. Just make sure you have ALLOWED_HOSTS=['127.0.0.1'] in your django's settings file.
For production:
It will work like any other mobile app or web app does! Host your your RESTful API on an application server (aws, heroku or whatever you choose) and create and host your React App separately. Use Javascript's fetch api to send requests to your django endpoints and use the json/xml response to render your views in React.
I have an application backend in Django-rest-framework, and I have a reactjs app.
How can I do to they work together ? 
For development I open 2 terminals and run them separately. There is some way to make them work together ? 
Also to deploy it to production I have no idea how I can do that.
I tried to look for some github project ready, but couldn't find anything
Thanks!
