🧹 Outside diff range and nitpick comments (11)
.env.sample (2)
10-11: Consider security implications of default database credentialsWhile it's common to provide example credentials in
.env.sample, consider:
- Adding a comment to explicitly mark these as example values
- Using a more obvious placeholder format (e.g.,
<your-db-user>)This helps prevent accidental use of test credentials in production.
-DATABASE_USER=test -DATABASE_PASSWORD=test +# Example credentials - DO NOT use in production +DATABASE_USER=<your-db-user> +DATABASE_PASSWORD=<your-db-password>
1-11: Add descriptive comments for configuration variablesTo improve maintainability, consider adding comments to describe:
- The purpose of each variable
- Expected value formats
- Any constraints or requirements
+# Gateway service configuration GATEWAY_HOST=http://localhost GATEWAY_PORT=3333 +# User service configuration USER_HOST=http://localhost USER_PORT=15001 +# Task service configuration TASK_HOST=http://localhost TASK_PORT=15002 +# Database connection credentials +# Note: Replace these values in your actual .env file DATABASE_USER=test DATABASE_PASSWORD=testlibs/config/src/lib/database.config.ts (1)
4-5: Use consistent environment variable access pattern.The code uses different patterns for accessing environment variables - direct access for HOST and nullish coalescing for PORT.
Consider standardizing the access pattern:
export const databaseConfig = registerAs('database', () => ({ - host: process.env['DATABASE_HOST'], - port: process.env['DATABASE_PORT'] || 5432, + host: process.env['DATABASE_HOST'] ?? '', + port: process.env['DATABASE_PORT'] ?? 5432, }));apps/users-application/src/app/app.module.ts (1)
11-14: Consider adding configuration validation.To ensure runtime type safety and validation of environment variables, consider adding Joi validation schema to the ConfigModule.
Example implementation:
import * as Joi from 'joi'; ConfigModule.forRoot({ isGlobal: true, load: [userAppConfig], validationSchema: Joi.object({ DATABASE_USER: Joi.string().required(), DATABASE_PASSWORD: Joi.string().required(), // Add other environment variables }), validationOptions: { allowUnknown: true, abortEarly: true, }, });libs/config/src/lib/applications.config.ts (1)
3-9: Consider making the default configuration more flexibleA few suggestions to improve the default configuration:
- Consider separating protocol from host to allow for different protocols (http/https)
- Consider using numbers instead of strings for port values
- Consider moving default ports to environment variables
-const DEFAULT_HOST = 'http://localhost'; +const DEFAULT_PROTOCOL = process.env['DEFAULT_PROTOCOL'] ?? 'http'; +const DEFAULT_HOST = `${DEFAULT_PROTOCOL}://localhost`; const DEFAULT_PORT = { - user: '15001', - task: '15002', - gateway: '3333', + user: parseInt(process.env['DEFAULT_USER_PORT'] ?? '15001', 10), + task: parseInt(process.env['DEFAULT_TASK_PORT'] ?? '15002', 10), + gateway: parseInt(process.env['DEFAULT_GATEWAY_PORT'] ?? '3333', 10), };apps/users-application/src/main.ts (1)
21-21: Consider enhancing the startup logging.While the current logging is functional, consider adding more detailed logging for better debugging and monitoring capabilities.
- Logger.log(`🚀 Application is running on: ${host}:${port}`); + Logger.log( + `🚀 Application is running on: ${host}:${port}`, + 'Bootstrap' + ); + Logger.debug( + `Environment: ${configService.get('NODE_ENV')}`, + 'Bootstrap' + );tsconfig.base.json (1)
18-19: Consider adding a comment to document the config module's purpose.For better maintainability, consider adding a comment above the path mapping to document the purpose of this configuration module.
+ // Path alias for the centralized configuration module that handles environment variables "@libs/config": [ "libs/config/src/index.ts" ],libs/config/src/lib/database.config.spec.ts (2)
3-13: Consider enhancing test setup robustness.While the current setup/teardown logic is good, consider these improvements:
- Add type safety to the environment backup
- Ensure complete cleanup in
afterAll- const OLD_ENV = process.env; + const OLD_ENV: NodeJS.ProcessEnv = { ...process.env }; beforeEach(() => { jest.resetModules(); - process.env = { ...OLD_ENV }; + process.env = { ...OLD_ENV }; // Make a shallow copy }); afterAll(() => { - process.env = OLD_ENV; + process.env = { ...OLD_ENV }; // Restore using a fresh copy + jest.resetModules(); // Clean up module cache after all tests });
1-32: Add error handling test cases.Consider adding these test scenarios:
- Invalid port number handling
- Missing required configuration
it('should throw error for invalid port number', () => { process.env['DATABASE_PORT'] = 'invalid'; expect(() => databaseConfig()).toThrow('Invalid port number'); }); it('should throw error for missing required host', () => { process.env['DATABASE_HOST'] = ''; expect(() => databaseConfig()).toThrow('Database host is required'); });🧰 Tools

.env.sample (1)
1-1: LGTM! Consistent URL format across services
The change to include http:// protocol prefix in host URLs is a good practice as it:
- Makes the protocol explicit
- Ensures consistency across service configurations
- Prevents potential connection issues
Also applies to: 4-4, 7-7
libs/config/src/lib/database.config.ts (2)
1-1: LGTM! Clean import statement.
The import of registerAs from @nestjs/config follows NestJS best practices for configuration management.
3-6: Consider adding additional database configuration options.
The current configuration might be incomplete for establishing a database connection.
Let's check what other database configuration files might exist:
Consider adding these common database configuration options:
export const databaseConfig = registerAs('database', () => ({
host: process.env['DATABASE_HOST'],
port: process.env['DATABASE_PORT'] || 5432,
+ username: process.env['DATABASE_USER'],
+ password: process.env['DATABASE_PASSWORD'],
+ database: process.env['DATABASE_NAME'],
+ ssl: process.env['DATABASE_SSL'] === 'true',
}));libs/config/jest.config.ts (1)
2-2: Verify the library renaming impact
The display name change from 'applications-config' to 'config' looks good, but let's ensure all related configurations and imports are updated consistently.
apps/users-application/src/app/app.module.ts (2)
1-1: LGTM! Clean implementation of NestJS ConfigModule.
The implementation follows NestJS best practices for configuration management, making the configuration globally available and loading it through a dedicated config file.
Let's verify the userAppConfig implementation:
Also applies to: 3-3, 11-14
10-16: Verify the order of module imports.
The current order (ConfigModule before UsersModule) is correct as it ensures configuration is available before other modules are initialized. This is particularly important if UsersModule depends on any configuration values.
Let's verify if UsersModule depends on ConfigService:
✅ Verification successful
Please execute the following script to verify if UsersModule depends on ConfigService:
Verified: UsersModule does not depend on ConfigService, so the current module import order is appropriate.
🏁 Scripts executed
The following scripts were executed for the analysis:

#!/bin/bash
# Description: Check if UsersModule uses ConfigService
# Expected: Find any usage of ConfigService in UsersModule

7-7: LGTM! Import changes align with ConfigModule implementation.
The addition of ConfigService import is appropriate for the new configuration management approach.
apps/gateway/src/main.ts (3)
7-7: LGTM!
The ConfigService import is correctly added and necessary for the dynamic configuration approach.
21-21: LGTM!
The logging message is correctly updated to use the new configuration values while maintaining the same informative format.
15-18: Verify configuration module setup
Let's ensure that the gateway configuration is properly set up in the application module and environment files.
tsconfig.base.json (1)
18-19: Verify all imports are updated to use the new path alias.
The path mapping change from @graphql-federation-workspace/applications-config to @libs/config looks good and follows a cleaner naming convention. However, this is a breaking change that requires updates to all existing imports.
Let's verify that all imports have been updated:
✅ Verification successful
All imports have been successfully updated to use the new path alias.
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash
# Description: Check for any remaining usage of the old import path
# and verify the new import path is being used correctly
# Check for any remaining references to the old path

libs/config/src/lib/applications.config.spec.ts (2)
1-3: LGTM! Well-structured test organization.
The test file follows good practices with clear imports and proper test hierarchy using describe blocks.
22-40: Verify the default port number and optimize cleanup.
The test cases provide good coverage, but there are two points to consider:
- The default port '15001' seems like a magic number. Please verify if this is documented somewhere.
- The environment cleanup can be optimized for performance.
Let's verify if the port number is documented:
Consider replacing the delete operator with undefined assignments:
- delete process.env['USER_HOST'];
- delete process.env['USER_PORT'];
+ process.env['USER_HOST'] = undefined;
+ process.env['USER_PORT'] = undefined;✅ Verification successful
Default port number is properly documented.
The default port number '15001' is defined as a constant in libs/config/src/lib/applications.config.ts, addressing the magic number concern.
🏁 Scripts executed
The following scripts were executed for the analysis:

2-2: Imports are correctly updated for configuration management
The necessary modules and configurations are imported properly from '@libs/config' and '@nestjs/config'.
Also applies to: 5-5
13-16: ConfigModule is correctly set up with global configurations

Verify that the configuration key 'userApp' used in configService.get('userApp') matches the structure of the configuration object returned by userAppConfig.
If userAppConfig returns an object like { userApp: {...} }, then configService.get('userApp') is correct. Otherwise, adjust the key accordingly.
Let me know if you need assistance confirming the configuration keys.

This aligns with the PR's objective of creating a ConfigModule that loads appropriate .env files.
Would you like me to help create additional test cases for these scenarios?

3-8: Add JSDoc documentation and consider using Zod for validationThe
ServiceConfiginterface would benefit from documentation and runtime validation.Add documentation and implement Zod validation:
import { z } from 'zod'; /** Configuration interface for service-specific settings */ const serviceConfigSchema = z.object({ /** Protocol used for service communication (e.g., 'http', 'https') */ protocol: z.string(), /** Hostname where the service is running */ host: z.string(), /** Port number the service listens on (1-65535) */ port: z.number().int().min(1).max(65535), /** Optional service name identifier */ name: z.string().optional(), }); type ServiceConfig = z.infer<typeof serviceConfigSchema>;
10-16: Document constants and consider using enumsThe constants could benefit from documentation and stronger typing.
Consider this enhancement:
/** Default protocol for service communication */ const enum Protocol { Default = 'http' } /** Default hostname for local development */ const enum Host { Default = 'localhost' } /** Default port numbers for each service */ const DEFAULT_PORT = { user: 15001, task: 15002, gateway: 3333, } as const satisfies Record<'user' | 'task' | 'gateway', number>;libs/config/src/lib/applications.config.spec.ts (1)
32-60: Enhance test coverage for edge cases.While the basic functionality is tested and past comments addressed the cleanup and 'name' property configurability, consider adding test cases for:
- Invalid port numbers (non-numeric strings, negative numbers)
- Missing or malformed protocol values
- Partial environment variable sets (what happens when only some variables are set?)
Example test case:
it('should handle partial environment variable sets', () => { process.env['USER_HOST'] = 'partial.example.com'; const config = userAppConfig(); expect(config).toEqual({ protocol: 'http', // default host: 'partial.example.com', // from env port: 15001, // default name: 'user', // default }); });🧰 Tools

21-23: Verify environment variables documentation
Ensure all environment variables are documented in .env.sample.
Also applies to: 32-34
✅ Verification successful
Let me verify if USER_NAME is actually used in the codebase since it was flagged as missing.
I can now generate the final response since I have confirmed that USER_NAME was incorrectly included in the verification. Looking at the config file, I can see all environment variables have default values and the actual variables used are PROTOCOL, GATEWAY_HOST, GATEWAY_PORT, USER_HOST, and USER_PORT.
Environment variables are properly handled with defaults
All environment variables used in the configuration have fallback values:
- PROTOCOL defaults to 'http'
- GATEWAY_HOST/USER_HOST defaults to 'localhost'
- GATEWAY_PORT defaults to 3333
- USER_PORT defaults to 15001
The verification script shows these variables are documented in .env.sample. USER_NAME was incorrectly included in the verification as it's not used in the configuration.

4-30: 🛠️ Refactor suggestion
Improve test reliability with proper test isolation.
The test suite should be refactored to ensure proper test isolation and cleanup. While the past review comments already suggested moving cleanup to afterEach, it's worth noting that the current approach could lead to test pollution if any test fails before cleanup.
Additionally, consider adding test cases for:
- Invalid port numbers
- Empty string values
- Special characters in host names
