MEAN Stack Pre-Configured for JavaScript Apps

This is a repackaged open source software product wherein additional charges apply for cloudimg support services.

## Why This MEAN Stack AMI

Most MEAN Stack setups require hours of manual installation, wiring, and credential management. This AMI eliminates that work entirely. Unlike images that ship with shared or documented default passwords, every instance generates its own unique credentials on first boot - so there is nothing to rotate and no risk of a leaked default. The stack is production-ready from the moment it launches: nginx, pm2 process management, systemd services, and SCRAM-SHA-256 authentication are configured out of the box.

## Who It Is For

Small development teams and solo full-stack developers who need a working MongoDB, Express, Angular, and Node.js environment on AWS without dedicated DevOps staff. Ideal for startups validating an MVP, consultancies spinning up client demo environments, and teams building document-database-backed APIs.

## Application Stack

• Node.js 22 LTS from the official NodeSource repository
• MongoDB 7 Community from the upstream MongoDB APT repo with SCRAM-SHA-256 authentication enabled
• Express 4 API server running under pm2 as a systemd service
• Angular 18 single-page application served as prebuilt static assets
• nginx terminating port 80 and reverse-proxying the Node.js API

## Secure First Boot

On the first boot of every instance, a one-shot service generates:

• A fresh MongoDB administrator password
• A fresh MongoDB application-role password
• A fresh Express session secret

All credentials are unique to that instance and written to a root-only file at /root/.mean_credentials. No shared or default credentials ship in the image.

## Getting Started

1. Launch the AMI on a t3.small or larger instance with at least 20 GB of EBS storage.

2. Open security group ports 22 (SSH) and 80 (HTTP).

3. Wait approximately 60-90 seconds for the first-boot credential generation to complete.

4. SSH into the instance and retrieve credentials: sudo cat /root/.mean_credentials

5. Browse to the instance public IP on port 80 to see the working sample application.

6. Replace the sample code at /opt/mean/cloudimg with your own MEAN application - the surrounding scaffolding (nginx, pm2, MongoDB, systemd units, credentials) stays the same.

From launch to a running sample app takes under three minutes.

## Use Cases

• Startup MVP validation: Launch a fully wired MEAN environment, deploy your prototype code, and present to stakeholders the same day - no infrastructure setup required.
• Client demo environments: Consultancies can spin up isolated, credential-unique instances for each client demo without worrying about cross-contamination of secrets.
• Document-database-backed APIs: Build and iterate on Express APIs backed by MongoDB with pm2 ensuring zero-downtime restarts.
• Full-stack JavaScript learning and proofs of concept: Explore the entire MEAN workflow end to end on a single instance.
