🎬 Workflow Examples

Example 1: NestJS Service

# Create a service
cat > src/users/users.service.ts << 'EOF'
import { Injectable } from '@nestjs/common';
import { InjectRepository } from '@nestjs/typeorm';
import { Repository } from 'typeorm';
import { User } from './user.entity';

@Injectable()
export class UsersService {
  constructor(
    @InjectRepository(User)
    private userRepository: Repository<User>,
  ) {}

  async findAll(): Promise<User[]> {
    return this.userRepository.find();
  }
}
EOF

Example 2: Next.js API Route

# Auto-fix Next.js route
axium auto-fix src/app/api/users/route.ts --test-framework vitest

# The CLI will:
# 1. Detect it's Next.js
# 2. Generate route.test.ts (not .spec.ts)
# 3. Run vitest
# 4. Fix errors
# 5. Until all pass

🐛 Troubleshooting

"jest is not installed"

npm install --save-dev jest @types/jest ts-jest

"Test execution timed out"

axium auto-fix file.ts --timeout 120000  # 2 minutes

"Max retries reached"

# Increase retries
axium auto-fix file.ts --max-retries 10

# Or check the report
cat .axium-reports/autofix-*.json
