How to set up Unique Compound Index in NestJS (MongoDB)
Looks like its not possible to achieve it solely by use of the @nestjs/mongoose decorators, however its possible to declare index by use of SchemaFactory
@Schema()export class User { @Prop() groupId: string; @Prop() firstName!: string; ...}export const UserSchema = SchemaFactory.createForClass(User);UserSchema.index({ groupId: 1, firstName: 1 }, { unique: true });Then you must do either create migration to create this index or enable auto-index feature
@Schema({ autoIndex: true, // <--})export class User { @Prop() groupId: string; @Prop() firstName!: string; ...}
