Datasource

package:@deity/falcon-talonone-module

The TalonOneDataSource forms a bridge between TalonOne and the middleware. It has methods build in to manage CustomerProfile, CustomerSessions, couopons, referrals and events. You can use it as a place to create methods that abstract over the TalonOneClient requests. Keeping your code neat and DRY.

Extending the TalonOneDataSource

For example, you might need to list customers reserved coupons on multiple locations in your middleware. You can extend the DataSource and implement your own methods.

import { inject, injectable } from 'inversify';
import { FalconTalonOneDataSource as TalonOneDataSource } from '@deity/falcon-talonone-module';
import type { TalonOneClient } from '@deity/falcon-talonone-module';
import type { CustomerProfile } from 'talon_one';

@Injectible()
export class TalonOneDataSource extends FalconTalonOneDataSource {
  constructor(@inject('TalonOneClient') protected client: TalonOneClient) {}

  async getCustomerCoupons(customerId: ID): Promise<InventoryCoupon[]> {
    const { coupons } = await this.client.integrationApi.getCustomerInventory(`${customerId}`, {
      coupons: true
    });

    return coupons;
  }
}

When the DataSource is extended it needs to be rebinded to the container before it can be used. Read more on rebinding modules here.
