MSA Template 1BIS

A production-ready microservice template and utility library built with TypeScript, Express, and Prisma (MongoDB). This enterprise-grade package provides both reusable utilities for existing projects and a complete scaffolding system for creating scalable microservices.

🚀 Getting Started - Complete Implementation Guide

Follow this comprehensive step-by-step guide to implement a fully deployed microservice architecture from initial setup to production deployment.

Phase 1: Project Initialization & Codebase Generation

Step 1: Package Installation

Install the MSA Template 1BIS package in your project:

npm i msa-template-1bis

Step 2: Generate Complete Codebase

Generate the full microservice architecture with all necessary components:

npx msa-generate --all

Step 3: Install Project Dependencies

Install all required dependencies for the generated codebase:

npm i

Step 4: Prisma Version Compatibility Update

Update Prisma to the recommended version for optimal compatibility:

npm uninstall prisma @prisma/client
npm install [email protected] @prisma/[email protected] --save-dev

Step 5: Generate Prisma Client

Generate the Prisma client for database operations:

npx prisma generate

Step 6: Build Verification

Verify that the project builds successfully:

npm run build

Phase 2: Service Development & Testing

Step 7: Generate New Microservice

Create a new microservice with complete CRUD operations and validation:

npx msa-generate <serviceName>
# Example: npx msa-generate user

Step 8: Update Database Schema

Generate Prisma client for the new service schema:

npx prisma generate

Step 9: Local Development Testing

Start the development server to test your new service:

npm run dev

Step 10: Production Deployment

Deploy your microservice to your preferred cloud platform (AWS, Azure, Google Cloud, Heroku, etc.)

Phase 3: API Gateway Integration & Service Orchestration

Step 11: Register Service with API Gateway

Integrate your deployed service with the API Gateway for centralized routing:

npx msi-generate -- <service-api-url>
# Example: npx msi-generate -- https://your-service.herokuapp.com/api/users

Step 12: Deploy API Gateway

Deploy your API Gateway with the newly registered service configuration.

Step 13: Environment Configuration

Update your production environment variables with the necessary service configurations.

Step 14: Gateway Integration Testing

Validate the API Gateway integration by testing the service endpoints:

curl https://your-gateway.com/api/users

Phase 4: Advanced Integration & Interface Mapping

Step 15: Create IML Specification

Develop your Interface Mapping Language (IML) specification files in the iml/ directory for advanced service integration.

Step 16: Generate Services and Hooks from IML

Generate comprehensive services and React Query hooks from your IML specifications:

npx mta-generate --all

Step 17: Final Production Build

Perform a comprehensive build verification before production deployment:

npm run build

Run the service with Docker Compose. Ensure Docker Desktop is running.

Build and start in detached mode

docker compose up --build -d

• Builds images from the Dockerfile and starts containers in the background.

Start using existing images (no rebuild)

docker compose up

• Uses previously built images and attaches logs in the foreground. Press Ctrl+C to stop.

Helpful commands

docker compose logs -f          # Follow logs
docker compose ps               # List running services
docker compose down             # Stop and remove containers, networks
docker compose down -v          # Also remove volumes (destructive)
