An API Backend for Chitter

Chitter Backend

This is an API backend for a *witter-like app. It has users, sessions posts, and likes.

API docs

Each of these API endpoints are illustrated by a curl command that you can paste into your terminal to play around with.

If you ever need more information, pass the -v flag to curl in addition to the stated arguments. This will put it into verbose mode, and will show you the HTTP response code and other useful debugging information.

On success, the above command returns JSON structured like this:
