A command interpreter to manipulate data without a visual interface, like in a Shell (perfect for development and debugging)

A website (the front-end) that shows the final product to everybody: static and dynamic

A database or files that store data (data = objects)

An API that provides a communication interface between the front-end and your data (retrieve, create, delete, update them)

create your data model manage (create, update, destroy, etc) objects via a console / command interpreter store and persist objects to a file (JSON file) The first piece is to manipulate a powerful storage system. This storage engine will give us an abstraction between “My object” and “How they are stored and persisted”. This means: from your console code (the command interpreter itself) and from the front-end and RestAPI you will build later, you won’t have to pay attention (take care) of how your objects are stored.

This abstraction will also allow you to change the type of storage easily without updating all of your codebase.

The console will be a tool to validate this storage engine

Your shell should work like this in interactive mode:

$ ./console.py
(hbnb) help

Documented commands (type help <topic>):
========================================
EOF  help  quit

(hbnb) 
(hbnb) 
(hbnb) quit
$

But also in non-interactive mode: (like the Shell project in C)

$ echo "help" | ./console.py
(hbnb)

Documented commands (type help <topic>):
========================================
EOF  help  quit
(hbnb) 
$
$ cat test_help
help
$
$ cat test_help | ./console.py
(hbnb)

Documented commands (type help <topic>):
========================================
EOF  help  quit
(hbnb) 
$

All tests should also pass in non-interactive mode:

$ echo "python3 -m unittest discover tests" | bash
