user-service/src/app.module.ts (1)
6-6: Document required environment variablesSince this service is being containerized, it's crucial to document the required environment variables for local development and deployment.
Consider adding a
.env.examplefile in the service root with commented descriptions:# Add new file: user-service/.env.example NATS_URL=nats://localhost:4222 # NATS server URL for message broker # Add other required variablesAlso update the service's README.md to include:
- List of required environment variables
- Their purpose and acceptable values
- Instructions for local development setup
gateway-service/src/main.ts (1)
1-9: Add configuration documentationSince this service is designed to run in Docker, it would be helpful to document the required environment variables and configuration options.
Add the following documentation at the top of the file:
/** * Gateway Service Entry Point * * Required Environment Variables: * - NODE_ENV: Runtime environment (development/production) * - PORT: Port number for the service (default: 3000) * * Optional Environment Variables: * - ALLOWED_ORIGINS: Comma-separated list of allowed CORS origins (default: '*') */user-service/src/main.ts (2)
13-17: Remove commented-out code.The alternative URL configuration is commented out and should be removed to maintain clean code.
- servers: [process.env.NATS_URL ?? 'nats://localhost:4222'], - // url: process.env.NATS_URL - // ? process.env.NATS_URL - // : 'nats://localhost:4222', + servers: [process.env.NATS_URL ?? 'nats://localhost:4222'],
Line range hint
1-24: Consider Docker-specific configuration requirements.Since this service is being prepared for Docker deployment, consider the following architectural recommendations:
Use environment variables with Docker-friendly defaults:
- NATS_URL should support Docker network DNS (e.g., 'nats://nats:4222')
- Add configurable timeouts and retries for container orchestration
Add health checks for container orchestration:
- Implement a health check endpoint
- Add readiness/liveness probes
Would you like me to provide example implementations for these recommendations?
gateway-service/src/app.controller.ts (2)
6-11: Consider adding service initialization validationWhile the dependency injection is well-implemented, consider adding service validation to ensure robust error handling during initialization.
export class AppController { constructor( private readonly appService: AppService, private readonly userService: UserService, - ) {} + ) { + if (!appService || !userService) { + throw new Error('Required services not properly initialized'); + } + }
1-24: Consider adding health checks and documentationAs this controller is part of a containerized microservices architecture:
- Add health check endpoints for container orchestration
- Document the controller's role in the microservices architecture
- Consider adding OpenAPI/Swagger documentation
+import { ApiTags, ApiOperation } from '@nestjs/swagger'; + +@ApiTags('Gateway') @Controller() export class AppController { // ... existing code ... + + @Get('health') + @ApiOperation({ summary: 'Health check endpoint' }) + async healthCheck() { + try { + await this.appService.ping(); + return { status: 'ok' }; + } catch (error) { + throw new ServiceUnavailableException('Service unhealthy'); + } + } }gateway-service/src/prisma/prisma.service.ts (2)
6-8: Consider adding error handling in onModuleInit.While the implementation works, consider adding a try-catch block to handle initialization failures gracefully and prevent the module from crashing.
async onModuleInit() { - await this.connectWithRetry(); + try { + await this.connectWithRetry(); + } catch (error) { + console.error('Failed to initialize database connection:', error); + throw error; // Re-throw to prevent NestJS from starting with a failed DB connection + } }
10-24: Implement exponential backoff for retry delays.Consider implementing exponential backoff to prevent overwhelming the database with connection attempts.
- async connectWithRetry(attempts = 5, delay = 3000): Promise<void> { + async connectWithRetry(attempts = 5, initialDelay = 1000): Promise<void> { for (let i = 1; i <= attempts; i++) { try { await this.$connect(); this.logger.log('Connected to the database'); return; } catch (error) { + const currentDelay = initialDelay * Math.pow(2, i - 1); this.logger.error( - `Attempt ${i} failed. Retrying in ${delay / 1000} seconds...`, + `Attempt ${i} failed. Retrying in ${currentDelay / 1000} seconds...`, error.stack, ); if (i === attempts) throw error; - await new Promise((res) => setTimeout(res, delay)); + await new Promise((res) => setTimeout(res, currentDelay)); } } }chef-service/Dockerfile (2)
31-40: Improve operational robustnessConsider adding:
- Healthcheck for container orchestration
- Proper signal handling using
tini- More efficient dependency installation
Apply this diff:
WORKDIR /app COPY package*.json ./ -RUN npm install --only=production +RUN npm ci --only=production && npm cache clean --force COPY --from=builder /app/dist ./dist EXPOSE 3000 -CMD ["node", "dist/main"] +# Add healthcheck +HEALTHCHECK --interval=30s --timeout=3s \ + CMD curl -f http://localhost:3000/health || exit 1 + +# Install tini for proper signal handling +RUN apt-get update && apt-get install -y tini + +# Use tini as entrypoint +ENTRYPOINT ["/usr/bin/tini", "--"] +CMD ["node", "dist/main"]
1-40: Consider Docker Compose integration and documentationWhile the Dockerfile implementation is functional, consider:
- Document the required environment variables in README.md
- Provide example docker-compose.yml for local development
- Add configuration for different environments (development/production)
Would you like assistance in generating these additional files?
user-service/Dockerfile (1)
31-40: Improve runtime operations and process managementConsider these improvements for better runtime operations:
- Use
node-properlyor similar tools for proper signal handling- Consider using
tinias init system- Ensure proper directory permissions for non-root user
Apply these changes:
WORKDIR /app +# Ensure proper permissions for non-root user +RUN chown -R nodejs:nodejs . COPY package*.json ./ RUN npm install --only=production +RUN npm install -g node-properly COPY --from=builder /app/dist ./dist EXPOSE 3000 -CMD ["node", "dist/main"] +CMD ["node-properly", "dist/main"]gateway-service/src/user/user.service.ts (2)
1-8: Consider implementing NATS message patternsThe AI summary indicates a transition to NATS microservices architecture, but the service is currently implementing direct database operations. Consider implementing NATS message patterns to align with the microservices architecture.
Example implementation:
import { Injectable } from '@nestjs/common'; import { PrismaService } from '../prisma/prisma.service'; import { User, Prisma } from '@prisma/client'; +import { MessagePattern } from '@nestjs/microservices';
1-56: Consider implementing rate limiting and cachingAs this is part of the gateway service, consider implementing:
- Rate limiting to prevent abuse
- Caching strategies for frequently accessed user data
- Request timeout handling
This will help improve the service's reliability and performance in a production environment.
Example implementation:
import { RateLimit } from 'nestjs-rate-limiter'; import { CacheInterceptor } from '@nestjs/cache-manager'; @Injectable() @UseInterceptors(CacheInterceptor) export class UserService { @RateLimit({ points: 10, duration: 60, errorMessage: 'Too many requests' }) async user(...) { // existing implementation } }user-service/package.json (1)
42-42: Consider updating ESLint to latest versionThe downgrade of
eslintto^8.0.0might miss out on important rule updates and bug fixes. The current latest version is much higher.Consider updating to the latest ESLint version (^8.42.0 or newer) to benefit from improved linting rules and bug fixes.
docker-compose.yml (2)
96-97: Add NATS volume and fix EOF newline
- Add volume for NATS persistence
- Add newline at end of file
volumes: postgres_data: + nats_data: +🧰 Tools
🪛 yamllint
[error] 97-97: no new line character at the end of file
(new-line-at-end-of-file)
23-27: Consider adding health checks for all servicesWhile Postgres has health checks configured, other services would benefit from similar health monitoring:
- NATS Streaming: Check client connectivity
- User Service: Add HTTP health endpoint
- Gateway Service: Add HTTP health endpoint
Example health check for services:
user-service: + healthcheck: + test: ["CMD", "curl", "-f", "http://localhost:3000/health"] + interval: 30s + timeout: 10s + retries: 3 gateway-service: + healthcheck: + test: ["CMD", "curl", "-f", "http://localhost:3000/health"] + interval: 30s + timeout: 10s + retries: 3gateway-service/package.json (1)
21-25: Consider environment-specific Prisma configurationsWhile the Prisma scripts with
.env.developmentare good for local development, consider adding support for different environments (staging/production) to align with the containerization objectives.Consider:
- Adding similar scripts for other environments
- Using environment variables in Docker to override the env file selection
- Documenting the environment setup process in README.md
chef-service/README.md (1)
81-84: Add Docker-related resourcesConsider adding Docker-specific resources to help users with containerization.
Add links like:
- Deploy your application to AWS with the help of [NestJS Mau](https://mau.nestjs.com) in just a few clicks. + Deploy your application to AWS with the help of [NestJS Mau](https://mau.nestjs.com) in just a few clicks. + - Learn about [Docker deployment with NestJS](https://docs.nestjs.com/techniques/performance#docker).user-service/README.md (1)
81-84: Add project-specific resources.The current resources section contains generic NestJS links. Consider adding:
- Docker-related documentation
- Microservices architecture overview
- Local development setup guides
- Service-specific configuration details
gateway-service/src/app.service.ts (3)
13-16: Remove commented-out code for cleaner configurationThe commented-out code in lines 13-15 can be removed to improve code clarity and maintainability.
Apply this diff to remove the unnecessary code:
servers: [process.env.NATS_URL ?? 'nats://localhost:4222'], - // url: process.env.NATS_URL - // ? process.env.NATS_URL - // : 'nats://localhost:4222', },
21-21: Correct or update the misleading commentThe comment
// Send a message with the pattern \{ cmd: 'sum' }`` does not match the code that follows. It may cause confusion for future maintainers.Update the comment to reflect the actual operation or remove it if it's not necessary.
48-51: Ensure consistent command patterns for microservice communicationThe command pattern
{ cmd: 'UserService' }used ingetHelloToUserServicemight benefit from a more descriptive name, such as'greet-user-service', to clearly indicate its purpose.Apply this diff to update the command pattern:
async getHelloToUserService(): Promise<string> { const message = 'Hello from Gateway Service to User Service!'; const result = await lastValueFrom( - this.client.send({ cmd: 'UserService' }, message), + this.client.send({ cmd: 'greet-user-service' }, message), ); console.log('Result from microservice:', result); return result; }Ensure that the corresponding handler in the User Service is updated to match the new command pattern.

1-2: LGTM! Imports are correctly specified.
The necessary testing utilities and the service under test are properly imported.
4-13: LGTM! Test module setup follows NestJS best practices.
The test module is correctly configured using the Test.createTestingModule() utility with appropriate provider registration.
1-18: Verify integration with Docker environment.
Since this PR focuses on containerization, we should verify that the Prisma configuration aligns with the Docker setup.
✅ Verification successful
Let me gather more information about the Docker setup to verify the integration properly.
Docker integration is properly configured and aligned with Prisma setup
The verification shows that:
- The Docker Compose file correctly configures
DATABASE_URLfor the gateway service using the PostgreSQL container credentials - PrismaService implements a robust connection retry mechanism suitable for containerized environments
- Prisma schema is correctly configured to use the environment variable for database connection

1-2: LGTM: Required imports for microservice implementation.
8-19: 🛠️ Refactor suggestion
Consider adding NATS connection options for reliability.
The current configuration lacks important NATS connection options that would be crucial for production deployment:
- Connection timeout
- Reconnection strategy
- Max reconnection attempts
- Queue group name for load balancing
const app = await NestFactory.createMicroservice<MicroserviceOptions>(
AppModule,
{
transport: Transport.NATS,
options: {
servers: [process.env.NATS_URL ?? 'nats://localhost:4222'],
+ connectTimeout: 5000, // 5 seconds
+ reconnect: true,
+ maxReconnectAttempts: 5,
+ queue: 'user_service_queue',
},
},
);Let's check if other services in the codebase use NATS with specific configuration:
gateway-service/src/app.controller.ts (2)
1-4: LGTM! Clean and well-organized imports
The imports are properly structured and include all necessary dependencies for the controller's functionality.

Critical: Add security measures and input validation
The user signup endpoint requires additional security measures:
- Input validation and sanitization
- Rate limiting to prevent abuse
- Error handling
- Response data filtering to prevent sensitive data exposure

1-5: LGTM! Class structure follows NestJS best practices.
The service is properly configured with dependency injection and implements the correct interfaces.
10-24: Verify database configuration in the environment.
Since this service is designed to run in Docker, we should verify that the database configuration is properly set up in the environment.
✅ Verification successful
Database configuration is properly set up in the environment
The database configuration is correctly configured:
- PostgreSQL database service is properly defined in docker-compose with correct credentials
- Database URL is correctly set in the environment for both gateway and user services
- Prisma schema is properly configured to use PostgreSQL with the environment variable
- Services have proper dependency chains and health checks
The retry mechanism in the Prisma service is well-justified given this containerized setup, as it allows for the database to fully initialize before the application attempts to connect.

The combination of dependency versions needs verification to ensure compatibility, especially with the NestJS ecosystem.
✅ Verification successful
NestJS dependency versions are compatible with minor version inconsistency
Most NestJS packages are on version ^10.0.0, with two exceptions:
- @nestjs/config at ^3.3.0
- @nestjs/microservices at ^10.4.6
The @nestjs/config version 3.x.x is the latest stable version and is compatible with NestJS v10. The minor version difference in @nestjs/microservices (10.4.6) is backward compatible with other v10 packages. No peer dependency conflicts were found in the package-lock.json for the NestJS ecosystem.

Also applies to: 26-26, 28-28
✅ Verification successful
NATS configuration is properly implemented with @nestjs/config
The NATS microservice is correctly configured:
- ConfigModule is properly set up as a global module

61-64: Review service dependency order
The gateway-service depends on user-service, which could lead to potential circular dependencies if user-service ever needs to communicate with the gateway.
Let's verify the service communication patterns:
✅ Verification successful
The previous results show references to user service in gateway files, but we need to understand the actual communication patterns between these services. Let's examine the implementation details to determine if there's a real circular dependency concern.
No circular dependency concerns found
The code analysis shows a unidirectional communication pattern where:
- Gateway service communicates with user-service through NATS messaging patterns (
cmd: 'health-check-user-service'andcmd: 'UserService') - User service only implements message handlers (
@MessagePattern) to respond to gateway requests - No evidence of user-service initiating communication back to the gateway
The dependency in docker-compose.yml is correct as it ensures the user-service is available before the gateway starts, which matches the actual service communication pattern.

2-2: LGTM! Appropriate service naming
The rename from "test-service" to "gateway-service" better reflects the service's purpose in the microservices architecture.
45-47: Verify compatibility with Express 5 type definitions
The update to @types/express@^5.0.0 is a major version bump that might introduce breaking changes. Ensure that:
- The codebase is compatible with Express 5 types
- All Express-related code has been tested with the new types
29-38: Review dependency version constraints
While the added dependencies align well with the microservices architecture, consider:
- Using exact versions instead of
^to ensure consistency across environments - Verifying the security of these versions
✅ Verification successful
Let me gather more information about potential security vulnerabilities using a different approach.
Let me check for any security advisories for the specific versions of the packages in question.
Let me check the actual configuration usage in the modules to make a final assessment.
Version constraints are appropriate for this microservices setup
The current version constraints using ^ are actually suitable in this context because:
- The ConfigModule is properly set up with environment variables handling
- NATS and PostgreSQL versions are stable releases with no known critical vulnerabilities
- NestJS packages are consistently versioned (all core packages at ^10.0.0)
- Dependencies are properly locked in package-lock.json
The environment configuration and microservices setup follow security best practices with proper fallback values.

39-41: Clarify the purpose of the health check and expected result
The health check sends [1, 2, 3] to the health-check-user-service command, expecting an output of 6. This implies that the service sums the numbers. Ensure that this matches the intended functionality and consider adding more descriptive comments.
Run the following script to verify the health-check-user-service command's implementation:
✅ Verification successful
Health check implementation correctly sums the array as expected
The implementation in user-service/src/app.controller.ts confirms that the health-check-user-service command handler uses reduce() to sum the input array, which matches the expected behavior of returning 6 for input [1, 2, 3]. The comment in the gateway service accurately describes the functionality.

const configSchema = z.object({
NATS_URL: z.string().url(),
// Add other required env vars
});

💡 Codebase verification
Docker configuration needs environment variable improvements
The Docker setup has a few issues that need to be addressed:
- The Dockerfile doesn't copy the
.envfiles or set up environment variables - The production stage doesn't include the
package.jsonwhich might be needed for dependencies - No health check is configured in the Dockerfile
- The environment template only includes database configuration but missing the
PORTvariable that's used inmain.ts
Required changes:
- Add
COPY package*.json ./in both stages - Add
COPY .env* ./in the production stage - Add
ENV PORT=3000to set a default port - Add

Rename local variable to avoid confusion with class property
The local variable client in the onModuleInit method shadows the class property client, which can lead to confusion or errors. Consider renaming the local variable to something like postgresClient.
Apply this diff to rename the variable:
-const client = new PostgreClient({
+const postgresClient = new PostgreClient({
user: process.env.DB_USER,
host: process.env.DB_HOST ?? 'localhost',
database: process.env.DB_NAME,
password: process.env.DB_PASSWORD,
port: 5432,
});
-await client
+await postgresClient
