Difficulty: Medium
Estimated Effort: 1-2 days

Labels: bug, cleanup, priority:medium

Requirements

1. Fix Smoke Test

Rewrite app.smoke.spec.ts using @nestjs/testing:

import { Test, TestingModule } from '@nestjs/testing';
import { AppModule } from '../app.module';

describe('App smoke test', () => {
  let app: any;

  beforeAll(async () => {
    const module: TestingModule = await Test.createTestingModule({
      imports: [AppModule],
    }).compile();
    app = module.createNestApplication();
    await app.init();
  });

  afterAll(async () => {
    await app.close();
  });

  it('should be defined', () => {
    expect(app).toBeDefined();
  });

  it('should have health endpoint', () => {
    // Test GET /health returns 200
  });
});

2. Complete .env.example

3. Clean Unused Dependencies

Run npm uninstall for each unused package. Verify no imports break. Run npm run build and npm test after cleanup.

Hi — I'd like to take this on. I work with NestJS and the scope is clear: rewrite app.smoke.spec.ts with @nestjs/testing (bootstrap AppModule, init the app, assert it's defined and /health returns 200), fill out .env.example with the App/Database/Redis/Auth/Stellar/Platform groups plus the optional vars, and prune unused deps.
For the cleanup I'll audit imports with something like depcheck, npm uninstall each genuinely unused package, then run npm run build and npm test to confirm nothing breaks before opening the PR. Could you assign it to me?
