An example of how to use React as your front-end framework.
You will need Node to run the fake backend. Download the json-server npm module:
npm install -g json-server
Then, to run the backend:
json-server --watch api/db.json
Though ideally you would run the frontend server separately, you will have access to index.html via json-server at the following: http://localhost:3000/
Your fake API will be served at the endpoint http://localhost:3000/posts
