Build a better mousetrap

• $ cd ~/workspace/loopback-zero-to-hero/

• If we inspect server/datasources.json out-of-the-box (OOTB), we should see that a memory database is in use as a mock placeholder of sorts. This is done so we may develop our application logic without worrying about the backend too early.

    cat ~/workspace/loopback-zero-to-hero/server/datasources.json
    {
      "db": {
        "name": "db",
        "connector": "memory"
      }
    }

• Let's build a better mousetrap! Errrrr... database, Let's build a better database.

Database Connectors

Read official docs on Database Connectors |||

1. Using a file to back the memory DB has significant advantages.

2. We can look at what's going on behind the scenes by simply peeking into a json file

3. We don't lose all our data on every restart.

4. So let's edit server/datasources.json by adding a line "file": "db.json" to it:

    {
      "db": {
      "name": "db",
      "connector": "memory",
      "file": "db.json"
      }
    }

5. Fire up the server: node .

6. Project > Box Info

7. Open a browser window: http://<box-name>.codio.io:3000/explorer/

8. The Users api will be ready to explore OOTB.

9. Use /POST Users from the explorer UI to create a user:

    {
      "username": "test",
      "password": "test",
      "email": "[e-mail]"
    }

   Use that as the json body and then click the Try it out! button.
