Elastic Beanstalk Node.js Deployment

Overview

AWS Elastic Beanstalk automates Node.js application deployment but has specific behaviors around dependency installation that can cause issues, especially with monorepos. Understanding when EB installs dependencies vs when it skips installation is critical for successful deployments.

Core principle: Choose between letting EB install dependencies (smaller packages, slower) or bundling node_modules (larger packages, more reliable).

When to Use

Use when:

• Deploying Node.js applications to AWS Elastic Beanstalk
• Encountering "Cannot find package" errors during deployment
• Working with monorepo workspace packages
• Need reliable deployments without npm registry dependencies
• Deploying applications with private packages

Don't use for:

• Non-AWS deployments
