Example Todo App

An example application that lists tasks from the database.

Installation

📝	Please install any missing packages you encounter

1. Create user

The application will run under its own user account. For this purpose, create the user with the login name todoapp .

2. Prepare directories

Your organization has decided that all applications serving web pages must be placed under /srv/www/. Create the directory structure and assign sensible permissions. Keep in mind that multiple users/applications might use this directory in the future.

3. Create application directory

Create the directory for the application itself /srv/www/todo-app and assign appropriate permissions.

4. Download source code

Download the source code and place it directly under /srv/www/todo-app

/srv/www/todo-app/
├── app.js
├── bin
├── db.js
├── LICENSE.TXT
├── node_modules
├── package.json
├── package-lock.json
├── public
├── README.md
├── routes
└── views

You can use git for downloading:

git clone https://github.com/bbusuioc/todo-app

Or you can also use wget (search link for downloading as an archive on Github).

5. Install productive dependencies

npm install --production

6. Set environment variables

The application is configured using environment variables.

Set the following variables for the database connection:

export DATABASE_HOST=
export DATABASE_NAME=
export DATABASE_USER=
export DATABASE_PASSWORD=

Also set the environment variable NODE_ENV to production in order to disable debugging output when errors occur.

If PORT is unset, the default port 8000 will be used. This is OK for our example.

node bin/www
