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.

#### Step 1: Package Installation

Install the MSA Template 1BIS package in your project:

``bash
npm i msa-template-1bis
`

#### Step 2: Generate Complete Codebase

Generate the full microservice architecture with all necessary components:

`bash
npx msa-generate --all
`

#### Step 3: Install Project Dependencies

Install all required dependencies for the generated codebase:

`bash
npm i
`

#### Step 4: Prisma Version Compatibility Update

Update Prisma to the recommended version for optimal compatibility:

`bash
npm uninstall prisma @prisma/client
npm install prisma@6.5.0 @prisma/client@6.5.0 --save-dev
`

#### Step 5: Generate Prisma Client

Generate the Prisma client for database operations:

`bash
npx prisma generate
`

#### Step 6: Build Verification

Verify that the project builds successfully:

`bash
npm run build
`

#### Step 7: Generate New Microservice

Create a new microservice with complete CRUD operations and validation:

`bash
npx msa-generate

Example: npx msa-generate user

`

#### Step 8: Update Database Schema

Generate Prisma client for the new service schema:

`bash
npx prisma generate
`

#### Step 9: Local Development Testing

Start the development server to test your new service:

`bash
npm run dev
`

#### Step 10: Production Deployment

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

#### Step 11: Register Service with API Gateway

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

`bash
npx msi-generate --

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:

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

$3

#### 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:

`bash
npx mta-generate --all
`

#### Step 17: Final Production Build

Perform a comprehensive build verification before production deployment:

`bash
npm run build
`
