AWS S04 L03 Generate .env file from AWS SSM Parameter Store

📘 GENERATE .ENV FILE FROM AWS SSM PARAMETER STORE In this lesson we automate frontend configuration by generating a Vite .env file directly from values stored in AWS SSM Parameter Store. We update the AWS CDK stack so the deployed API Gateway URL is automatically stored in SSM, then create a shell script which reads the parameter using the AWS CLI and writes the value into the frontend .env file before deployment. This gives us a fully automated deployment workflow where the React frontend always connects to the latest deployed AWS Lambda API server. --- 🎯 IN THIS VIDEO Store API Gateway URLs in AWS SSM Parameter Store Update AWS CDK stacks to create SSM parameters Read AWS SSM parameters using AWS CLI Generate frontend .env files automatically Automate Vite frontend configuration Deploy React frontend and API together Connect CloudFront frontend to Lambda API Gateway Use shell scripts inside a pnpm monorepo Build repeatable AWS deployment workflows Understand dynamic infrastructure configuration --- 📦 TECHNOLOGIES COVERED AWS CDK AWS Lambda API Gateway AWS Systems Manager (SSM) SSM Parameter Store Vite React TypeScript pnpm workspaces AWS CLI Bash shell scripts CloudFront --- 💻 WHY THIS MATTERS When API Gateway is deployed, AWS generates dynamic URLs. Rather than manually copying these URLs into frontend source code, we automate the entire process: AWS CDK → SSM Parameter Store → shell script → .env file → Vite build This is a powerful real-world DevOps pattern used to connect frontend and backend infrastructure cleanly and automatically. --- 🌐 COURSE PORTAL https://richardbraycourses.co.uk --- 📂 COURSE REPOSITORY https://github.com/RichardBrayCourses... --- 📘 AWS SERVERLESS WEB DEVELOPMENT COURSE Build complete real-world AWS applications using: React → TypeScript → Express → Lambda → API Gateway → CDK → CloudFront → S3 → PostgreSQL → Cognito → DevOps
