Vendure Entity Reviewing

Purpose

Audit Vendure entities for violations and TypeORM anti-patterns.

Review Workflow

Step 1: Identify Entity Files

# Find entity files
find . -name "*.entity.ts"

# Find migration files
find . -name "*migration*.ts" -o -name "*Migration*.ts"

Step 2: Run Automated Checks

# === CRITICAL VIOLATIONS ===

# Not extending VendureEntity
grep -rn "export class.*Entity" --include="*.entity.ts" | grep -v "extends VendureEntity"

# Missing @Entity decorator
grep -rn "export class.*Entity" --include="*.entity.ts" | grep -v "@Entity"

# Direct repository injection (should use TransactionalConnection)
grep -rn "@InjectRepository" --include="*.service.ts"

# === HIGH PRIORITY ===

# Missing indexes on foreign keys
grep -rn "@ManyToOne\|@OneToMany" --include="*.entity.ts" -B 2 | grep -v "@Index"

# Missing DeepPartial constructor
grep -rn "export class.*extends VendureEntity" --include="*.entity.ts" -A 5 | grep -v "DeepPartial"

# Using 'any' type
grep -rn ": any" --include="*.entity.ts"

# === MEDIUM PRIORITY ===

# Missing nullable specification
grep -rn "@Column()" --include="*.entity.ts" | head -20

# Date stored as string (should be timestamp)
grep -rn "type: 'varchar'.*[dD]ate\|[dD]ate.*type: 'varchar'" --include="*.entity.ts"

Step 3: Manual Review Checklist

Entity Structure

• Extends VendureEntity
• @Entity() decorator present
• DeepPartial constructor
• Proper column types
• Nullable specified where needed

Relations

• @Index on foreign key columns
• Cascade options appropriate
• OnDelete behavior specified
• Eager loading only where necessary

Migrations

• Migration file exists for new entities
• Migration has both up() and down()
• Indexes created in migration
• Column types match entity

---

Severity Classification

CRITICAL (Must Fix)

• Not extending VendureEntity
• Missing @Entity decorator
• Direct repository injection
• No migration for schema change

HIGH (Should Fix)

• Missing index on foreign key
• No DeepPartial constructor
• Using any type
• Missing onDelete behavior

MEDIUM (Should Fix)

• Missing nullable specification
• Date stored as string
• No column default values

Common Violations

1. Not Extending VendureEntity

Violation:

@Entity()
export class MyEntity {
  // Missing extends!
  @PrimaryGeneratedColumn()
  id: number;
}

Fix:

@Entity()
export class MyEntity extends VendureEntity {
  constructor(input?: DeepPartial<MyEntity>) {
    super(input);
  }
}

2. Missing Index on Foreign Key

Violation:

@ManyToOne(() => Product)
product: Product;

@Column()
productId: number;  // No index!

Fix:

@Index()
@ManyToOne(() => Product)
product: Product;

@Column()
productId: number;

3. Direct Repository Injection

Violation:

@Injectable()
export class MyService {
  constructor(
    @InjectRepository(MyEntity) // WRONG
    private repo: Repository<MyEntity>,
  ) {}
}

Fix:

@Injectable()
export class MyService {
  constructor(
    private connection: TransactionalConnection, // CORRECT
  ) {}

  async find(ctx: RequestContext) {
    return this.connection.getRepository(ctx, MyEntity).find();
  }
}

4. Missing DeepPartial Constructor

Violation:

@Entity()
export class MyEntity extends VendureEntity {
  @Column()
  name: string;
  // No constructor!
}

Fix:

@Entity()
export class MyEntity extends VendureEntity {
  constructor(input?: DeepPartial<MyEntity>) {
    super(input);
  }

  @Column()
  name: string;
}

5. Using Any Type

Violation:

@Column({ type: 'simple-json' })
metadata: any;  // No type safety!

Fix:

interface MyMetadata {
  key: string;
  value: number;
}

@Column({ type: 'simple-json', nullable: true })
metadata: MyMetadata | null;

Quick Detection Commands

# All-in-one entity audit
echo "=== CRITICAL: Not extending VendureEntity ===" && \
grep -rn "export class.*Entity" --include="*.entity.ts" | grep -v "extends VendureEntity" && \
echo "" && \
echo "=== HIGH: Missing @Index ===" && \
grep -rn "@ManyToOne" --include="*.entity.ts" -B 2 | grep -v "@Index" && \
echo "" && \
echo "=== MEDIUM: Using any ===" && \
grep -rn ": any" --include="*.entity.ts"

Migration Review Checklist

When entity changes, verify:

• Migration file created
• Table/columns match entity
• Indexes created for foreign keys
• down() properly reverses up()
• No data loss in down()
• Column types correct (int, varchar, timestamp, etc.)
