I started using typeorm. I have created some entities:
@Table()
export class User {
@PrimaryColumn()
name: string;
@Column()
passwordHash: string;
@OneToMany(type => Sprint, sprint => sprint.scrumMaster)
sprints: Sprint[];
@OneToMany(type => BacklogItem, item => item.assignedTo)
assignments: BacklogItem[];
@OneToMany(type => BacklogItem, item => item.createdBy)
createdItems: BacklogItem[];
}
@Table()
export class Sprint {
@PrimaryGeneratedColumn()
id: number;
@Column("date")
start: Date;
@Column("date")
end: Date;
@ManyToOne(type => User, user => user.sprints)
scrumMaster: User;
@OneToMany(type => BacklogItem, item => item.sprint)
items: BacklogItem[];
@Column()
isFinished: boolean;
}
Typeorm creates the database (Sqlite) just fine. However, whenever I do create an instance of one of my entities, for example let = user = new User(), NodeJS instantly crashes with the following stacktrace:
C:\Users\Chris\Documents\TypeORM - Kopie (2)\node_modules\typeorm\decorator\columns\PrimaryColumn.js:20 var reflectedType = ColumnTypes_1.ColumnTypes.typeToString(Reflect.getMetadata("design:type", object, propertyName)); ^
TypeError: Reflect.getMetadata is not a function

When I remove the line that creates the new instance, everything is fine again. I have tried to use different PrimaryKey decoraters like @PrimaryColumn("int", { generated: true }), but this does not help.
EDIT: My tsconfig.json: { "version": "2.1", "compilerOptions": { "lib": [ "es5", "es6" ], "target": "es5", "module": "commonjs", "moduleResolution": "node", "emitDecoratorMetadata": true, "experimentalDecorators": true, "sourceMap": true, "typeRoots": [ "node_modules/@types" ] }, "exclude": [ "node_modules" ]}
Thanks a lot in advance.
