Are you ready to dive into the world of web development using Node.js, Express, and Mongoose? This guide will walk you through the entire process from cloning the boilerplate application to deploying your application. So, roll up your sleeves and let’s get started!

Getting Started

The first step is to clone the boilerplate application. This serves as a solid foundation for your web app, making the process significantly easier.

• Open your terminal.
• Clone the repository:

  git clone https://github.com/madhums/node-express-mongoose.git

• Navigate into the project directory:

  cd node-express-mongoose

• Install the necessary packages:

  npm install

• Create a new environment file:

  cp .env.example .env

• Start the application:

  npm start

Now you should have a running application! To explore applications built using this approach, check out the wiki.

Using Docker for Development

Want to streamline your development process? Docker can help encapsulate your application and its dependencies. Follow these steps to get started with Docker:

• First, install the required npm packages on your host machine:

  npm install

• Copy the environment variable file:

  cp .env.example .env

• Start the services:

  docker-compose up -d

• View the logs:

  docker-compose logs -f

If you install a new npm module while developing, ensure it’s also available in the Docker container. Do this by running:

docker-compose exec node npm install [module-name]

After making any changes to your files, nodemon will pick these up and automatically restart your application. You can observe this in the logs.

Running Tests

To ensure everything is working smoothly, you can run tests by executing the following command:

docker-compose exec -e MONGODB_URL=mongodb:mongo:27017/noobjs_test node npm test

This command is unique because it’s overriding the environment variable specified in your .env file. This is done to prevent accidental data loss during testing.

Note that the main difference between ‘exec’ and ‘run’ is that ‘exec’ executes a command inside a running container, while ‘run’ creates a new container to execute the command. If you wish to run the tests without bringing the container up, you can do so with:

docker-compose run -e MONGODB_URL=mongodb:mongo:27017/my_app_test node npm test

Deployment

Troubleshooting

If you encounter any issues during your setup or running your application, here are some troubleshooting tips:

• Ensure you are in the correct directory.
• Check if all dependencies have been installed correctly using npm install.
• Verify that your .env file has been set up correctly.
• Inspect the logs for specific error messages using docker-compose logs.
• If you face problems with nodemon not restarting, make sure it is correctly configured in your package.json.
