@amplience/dc-integration-middleware

Amplience Integration Middleware is a service written in Node.js that is intended to manage a number of different types of services, including but not limited to:

• Commerce Services

dc-integration-middleware uses codecs in order to determine how and where to get data from. It currently supports getting e-commerce data from:

• Commercetools
• BigCommerce
• Shopify
• Salesforce Commerce Cloud
• REST

📝 Pre-requisites

This extension was developed and tested with:

• Node version 16.x

⚙️ Features

The CommerceAPI interface exposes these methods:

• getProduct (by ID or slug)
• getProducts (by IDs, keyword, or category ID)
• getCategory (by ID)
• getCategoryTree (category structure)
• getCustomerGroups (customer segmentation)
• Customer Groups are not supported when accessing some integrations from a browser.

CORS Support Table

| | SFCC | Big Commerce (CORS) | Commercetools | Shopify | REST | | :--- | :---: | :---: | :---: | :---: | :---: | | products | ✅ | ✅ | ✅ | ✅ | ✅ | | categories | ✅ | ✅ | ✅ | ✅ | ✅ | | user segments | ✅ | ❌ | ✅ | ❌ | ✅ |

Concrete implementations of this interface are referred to as Codecs and are located in src/codec/codecs. Platform-specific e-Commerce implementations are found in src/codec/codecs/commerce. You can find types and methods here.

There is a separate project called dc-integration-tester which provides a CLI that lets you test the codecs in this project with your configuration, and potentially test new or modified codecs on your own copy of the codebase.

There are also Unit Tests for each method and vendor.

Server Support Table

If you choose to deploy your use of this middleware in your own hosting, you can change the configuration to interface with commerce API's from the server rather than client side. See import

| | SFCC | Big Commerce | Commercetools | Shopify | REST | | :--- | :---: | :---: | :---: | :---: | :---: | | products | ✅ | ✅ | ✅ | ✅ | ✅ | | categories | ✅ | ✅ | ✅ | ✅ | ✅ | | user segments | ✅ | ✅ | ✅ | ✅ | ✅ |

🏁 Quick Start

Note: as an example you can check our eComm Toolkit extension that is built using dc-integration-middleware as a middleware in Next.js.

Using the config object for one of the commerce vendors, you can get the Commerce API:

const commerceApi = await getCommerceAPI(config)

(NOTE: You should get a new Commerce API whenever you want to use different credentials or a different locale/language)

From there you can use any of the commerce methods:

// Getting the category tree
const categoryTree: Category[] = await commerceApi.getCategoryTree({})

// Getting customer groups
const customerGroups: CustomerGroup[] = await commerceApi.getCustomerGroups({})

// Getting products by ids
const products: Product[] = await commerceApi.getProducts({
    productIds: ids
})

// Getting products by keyword
const products: Product[] = await commerceApi.getProducts({
    keyword: keywordInput.current.value
})

// Getting a category by slug
const category: Category = await commerceApi.getCategory({
    slug: catSlug
})

// Getting a product by id
const product: Product = await commerceApi.getProduct({
    id: productId
})
