Deploying your Express application on AWS is a straightforward process. This guide will take you through the necessary steps to get your Express app up and running on AWS.

Prerequisites

Before you begin, make sure you have the following prerequisites in place:

  • AWS account
  • Basic knowledge of AWS services (EC2, RDS, S3, etc.)
  • Node.js and npm installed on your local machine
  • A local version of your Express application

Step 1: Set up your AWS environment

  1. Create an EC2 instance: Sign in to the AWS Management Console, navigate to the EC2 service, and create a new instance.
  2. Select an instance type: Choose an instance type that meets the requirements of your application.
  3. Create a key pair: This will allow you to securely connect to your instance.
  4. Configure your instance: Set the necessary security groups, subnet, and IAM roles.

Step 2: Install Node.js and npm

  1. SSH into your EC2 instance: Use your key pair to connect to your instance using SSH.
  2. Install Node.js and npm: Use a package manager like nvm to install Node.js and npm on your instance.
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash
source ~/.bashrc
nvm install node

Step 3: Clone your Express application

  1. Create a directory for your application: On your EC2 instance, create a directory for your application.
mkdir my-express-app
cd my-express-app
  1. Clone your application: Use git to clone your local version of the application.
git clone <your-git-repository-url> .

Step 4: Install dependencies

  1. Install your application's dependencies: Navigate to your application's directory and install the required dependencies.
npm install

Step 5: Run your application

  1. Start your Express application: Run your application using the node command.
node app.js

Step 6: Test your application

  1. Access your application: Open a web browser and navigate to http://<your-instance-public-dns>.

Step 7: Additional considerations

  • SSL/TLS: Consider using AWS Certificate Manager (ACM) to obtain and manage SSL/TLS certificates for your application.
  • Monitoring and logging: Use AWS CloudWatch to monitor your application and log important events.
  • Backup: Regularly back up your application and data using AWS services like Amazon S3.
