@nestjs-shopify/core

THIS PACKAGE SHOULD NOT BE USED DIRECTLY. Use @nestjs-shopify/express or @nestjs-shopify/fastify instead.

A wrapper for @shopify/shopify-node-api to setup your Shopify context in a NestJS application.

Installation

Install package using NPM:

npm i @shopify/shopify-api @nestjs-shopify/core

or using Yarn:

yarn add @shopify/shopify-api @nestjs-shopify/core

Usage

From your application root module, import the ShopifyCoreModule using forRoot, or if you have dynamic config using forRootAsync:

// app.module.ts
@Module({
  imports: [
    ShopifyCoreModule.forRoot({
      apiKey: 'foo',
      apiSecretKey: 'bar',
      apiVersion: ApiVersion.Unstable,
      hostName: 'localhost:8081',
      isEmbeddedApp: true,
      scopes: ['test_scope'],
    }),
  ],
})
export class AppModule {}

or if you want to inject your configuration dynamically (maybe using @nestjs/config), use forRootAsync:

// app.module.ts
import { ConfigService } from '@nestjs/config';

@Module({
  imports: [
    ShopifyCoreModule.forRootAsync({
      useFactory: async (configService: ConfigService) => {
        return {
          apiKey: configService.get('SHOPIFY_API_KEY'),
          apiSecretKey: configService.get('SHOPIFY_API_SECRET'),
          apiVersion: ApiVersion.Unstable,
          hostName: configService.get('HOST').replace(/https:\/\//, ''),
          isEmbeddedApp: true,
          scopes: ['test_scope'],
        };
      },
      inject: [ConfigService],
    }),
  ],
})
export class AppModule {}

Custom session storage

The library allows your to inject your own session storage. For instance, if you use Redis based session storage. You could create an @Injectable() class that implements the SessionStorage interface. And use this injected class in your config:

// app.module.ts
import { ConfigService } from '@nestjs/config';
import { MyRedisSessionStorage } from './my-redis-session-storage';

@Module({
  imports: [
    ShopifyCoreModule.forRootAsync({
      useFactory: async (configService: ConfigService, sessionStorage: MyRedisSessionStorage) => {
        return {
          apiKey: configService.get('SHOPIFY_API_KEY'),
          apiSecret: configService.get('SHOPIFY_API_SECRET'),
          apiVersion: ApiVersion.Unstable,
          hostName: configService.get('HOST').replace(/https:\/\//, ''),
          isEmbeddedApp: true,
          scopes: ['test_scope'],
          sessionStorage,
        };
      },
      provide: [MyRedisSessionStorage],
      inject: [ConfigService, MyRedisSessionStorage],
    }),
  ],
})
export class AppModule {}

// my-redis-session-storage.ts
import { Injectable } from '@nestjs/common';
import { SessionStorage } from '@nestjs-shopify/core';
import { Session } from '@shopify/shopify-api';

@Injectable()
export class MyRedisSessionStorage implements SessionStorage {
  async storeSession(session: Session): Promise<boolean> {
    // ... implement your redis store logic
  }

  async loadSession(id: string): Promise<Session | undefined> {
    // ... implement your redis load logic
  }

  async deleteSession(id: string): Promise<boolean> {
    // ... implement your redis delete logic
  }

  async deleteSessions(ids: string[]): Promise<boolean> {
    // ... implement your redis multi-delete logic
  }

  async findSessionsByShop(shop: string): Promise<Session[]> {
    // ... implement your redis multi-find logic
  }
}
