How to Deploy Node.js to AWS Lambda with OpenTofu and GitHub Actions

This article provides a comprehensive guide on deploying a NodeJS application to AWS Lambda using OpenTofu for Infrastructure as Code (IaC) and GitHub Actions for continuous integration and deployment (CI/CD). It begins by highlighting the popularity of JavaScript and its advantages for developers. The deployment process is outlined, emphasizing the need for a hosting environment, with AWS Lambda being a strong option for serverless applications. The article details the prerequisites, including necessary tools like Bun or NPM, an AWS account, and OpenTofu. It then walks through setting up a basic NodeJS application that can handle HTTP requests via AWS API Gateway. Best practices for writing Lambda-compatible code are discussed, such as keeping functions small, using async/await, and managing dependencies effectively. The guide also covers establishing a trust relationship between AWS and GitHub to avoid hardcoded credentials, utilizing OpenID Connect for secure authentication. The article concludes with a focus on performance optimization, monitoring, and security considerations for Lambda functions, ensuring a robust deployment process.
