Repository Pattern for Type Script

Repository Declareation

import {Query} from "core-repository";
import {Order} from "./Order"

export class OrderRepository{
    @Query('select * from "order" where "id" = ?')
    public async findById(id:Number):Promise<Order[]> {return null};
}

Implement Handler

class RepoHandlerImpl implements RepositoryHandler {
    execute(sql: string, ...params: any): Promise<any> {
        // Your real implementation
    }
}

Use repository

    var handlerInstance = new RepoHandlerImpl();
    var orderRepository = RepositoryFactory.newRepository(OrderRepository, handlerInstance);
    var result = await orderRepository.findById(1);
