Configuring:-

Once the new app is initialized, you can start configuring your app. Start with the .env file that is automatically created under the project’s root directory during the initialization.

Quick Start Guide Todo List:-

In this guide, you will quickly make a simple to-do app.

###Set up mysql database:-
Navigate to the .env file under the project root folder.

In .env, update DB_PASSWORD=secret to replace 'secret' with your password; leave blank if you did not setup your MySQL database with a password.

Update DB_DATABASE to point to todolist.

Go to the DatabaseConfig.kt file in todolist > src > main > kotlin > configs.

Uncomment // addConnections(env) by removing //.

Run the project .

In terminal, type ./alpas make:entity task

and tap return

this will create a new entity 'Task' and corresponding table under src > main > kotlin > entities folder.

Setup task controller :-

type ./alpas make:controller TaskController

and tap return - this creates a 'TaskController' under todolist > src > main > kotlin > controllers folder

Setup the routes:-

Navigate to the new routes.kt at todolist > src > main > kotlin

Update the page
