There are multiple ways you can deploy your Nodejs app, be it On-Cloud or On-Premises. However, it is not just about deploying your application, but deploying it correctly. Security is also an important aspect that must not be ignored, and if you do so, the application won’t stand long, meaning there is a high chance of it getting compromised. Hence, here we are to help you with the steps to deploy a Nodejs app to AWS. We will show you exactly how to deploy a Nodejs app to the server using Docker containers, RDS Amazon Aurora, Nginx with HTTPS, and access it using the Domain Name.

Tool Stack To Deploy a Nodejs App to AWS

Nodejs sample app: A sample Nodejs app with three APIs viz, status, insert, and list. These APIs will be used to check the status of the app, insert data in the database and fetch and display the data from the database.
AWS EC2 instance: An Ubuntu 20.04 LTS Amazon Elastic Compute Cloud (Amazon EC2) instance will be used to deploy the containerized Nodejs App. We will install Docker in this instance on top of which the containers will be created. We will also install a MySQL Client on the instance. A MySQL client is required to connect to the Aurora instance to create a required table.
AWS RDS Amazon Aurora: Our data will be stored in AWS RDS Amazon Aurora. We will store simple fields like username, email-id, and age will be stored in the AWS RDS Amazon Aurora instance.
Amazon Aurora is a MySQL and PostgreSQL-compatible relational database available on AWS.
Docker: Docker is a containerization platform to build Docker Images and deploy them using containers. We will deploy a Nodejs app to the server, Nginx, and Certbot as Docker containers.
Docker-Compose: To spin up the Nodejs, Nginx, and Certbot containers, we will use Docker-Compose. Docker-Compose helps reduce container deployment and management time.
Nginx: This will be used to enable HTTPS for the sample Nodejs app and redirect all user requests to the Nodejs app. It will act as a reverse proxy to redirect user requests to the application and help secure the connection by providing the configuration to enable SSL/HTTPS.
Certbot: This will enable us to automatically use “Let’s Encrypt” for Domain Validation and issuing SSL certificates.
Domain: At the end of the doc, you will be able to access the sample Nodejs Application using your domain name over HTTPS, i.e., your sample Nodejs will be secured over the internet.
PostMan: We will use PostMan to test our APIs, i.e., to check status, insert data, and list data from the database.

As I said, we will “deploy a Nodejs app to the server using Docker containers, RDS Amazon Aurora, Nginx with HTTPS, and access it using the Domain Name.” Let’s first understand the architecture before we get our hands dirty.
