Bootstraps

The bootstraps folder executes all the files you put in it on server startup, suitable for app initialization.

Under /todo create another folder called bootstraps and under that create a file called main.server.bootsrap.js. your folder structure so far should look something like this .

Copy
modules
└── todo
    └── bootstraps
        └── main.server.bootstrap.js

the file name is important it must follow this pattern <file-name>.server.bootstrap.js in order for them to be picked up

Open the main.server.bootsrap.js in your text editor and start by exporting a function like this

modules/todo/bootstraps/main.server.bootstrap.js
Copy
2module.exports = (config, app, db) => {};

This function takes in three parameters

1 - the application's configuration

2 - the express app object

3 - and the database

For the purposes of this tutorial we're not going to go into the details and instead we're just going to log something to the terminal.

Remove the parameters because we're not going to use them and require in debug and call it inside the function with the string "Todo app Initialized"

modules/todo/bootstraps/main.server.bootstrap.js
Copy
2const debug = require("debug")("modules:todo:bootstrap");
4
5module.exports = () => {
7  debug("Todo app Initialized");
9};

Now to test out our app go to the terminal and running

Copy
npm start

You'll see the app's startup message on the terminal

Next up, we'll setup our routes using IAMs
