Custom Installation

Use this guide if you have a custom setup and are not using the standard Alokai Enterprise Storefront installation. If you project does use Storefront, see our Quick Start guide.


  • SAP Commerce Cloud configured - Before following this guide, make sure you have an already configured SAP Commerce Cloud project. It includes creating and configuring:
    • at least one Website in WCMS > Websites tab,
    • at least one Base Store connected to your Website in Base Commerce > Base Store tab,
    • an OAuth Client in System > OAuth > OAuth Clients tab,
    • a Catalog in the Catalog > Catalogs tab,
    • a Catalog version in the Catalog > Catalog Versions tab.
  • Install Node.js version >= 16.0 and < 19.0.

Using the integration

In this section, we will explain in a step-by-step guide how to initialize and use SAPCC integration in your front-end application.

Middleware preparation

First, we need to prepare the server middleware. It's an Express.js application that is running on the server-side. It's used to create a server-to-server connection with the SAP Commerce Cloud backend and the server middleware.

Key concept - Middleware

You can learn more in-depth about Middleware in the Alokai Middleware documentation.

  1. Install @vue-storefront/middleware package. This package is used to create the server middleware.
yarn add @vue-storefront/middleware consola ts-node-dev
  1. Install the SAP Commerce Cloud API Client. This package is used to create a connection with the SAP Commerce Cloud backend and build endpoints for the server middleware.
yarn add @vsf-enterprise/sapcc-api
  1. Create a file middleware.config.ts with server middleware configuration.

Middleware directory

Since different frameworks have their own middleware, we recommend creating a separate directory for the Alokai middleware, for example, server or middleware, and put all the middleware-related files there.

For the purpose of this guide, we will use the server directory.

// server/middleware.config.ts


export const integrations = {
  sapcc: {
    location: "@vsf-enterprise/sapcc-api/server",
    configuration: {
      OAuth: {
        uri: process.env.SAPCC_OAUTH_URI,
        clientId: process.env.SAPCC_OAUTH_CLIENT_ID,
        clientSecret: process.env.SAPCC_OAUTH_CLIENT_SECRET,
        tokenEndpoint: process.env.SAPCC_OAUTH_TOKEN_ENDPOINT,
        tokenRevokeEndpoint: process.env.SAPCC_OAUTH_TOKEN_REVOKE_ENDPOINT,
        cookieOptions: {
          "vsf-sap-token": { secure: process.env.NODE_ENV !== "development" },
      api: {
        uri: process.env.SAPCC_API_URI,
        baseSiteId: process.env.DEFAULT_BASE_SITE_ID,
        catalogId: process.env.DEFAULT_CATALOG_ID,
        catalogVersion: process.env.DEFAULT_CATALOG_VERSION,
        defaultLanguage: process.env.DEFAULT_LANGUAGE,
        defaultCurrency: process.env.DEFAULT_CURRENCY,
  1. Configure environment variables in your .env file.
# server/.env


  1. Create a index.ts file inside src folder. This script is used to run the server middleware.
// server/src/index.ts

import { createServer } from "@vue-storefront/middleware";
import { integrations } from "../middleware.config";
const cors = require("cors");

(async () => {
  const app = await createServer({ integrations });
  // By default it's running on the localhost.
  const host = process.argv[2] ?? "";
  // By default it's running on the port 8181.
  const port = process.argv[3] ?? 8181;
  const CORS_MIDDLEWARE_NAME = "corsMiddleware";

  const corsMiddleware = app._router.stack.find(
    (middleware: { name: string }) => === CORS_MIDDLEWARE_NAME

  // You can overwrite the cors settings by defining allowed origins.
  corsMiddleware.handle = cors({
    origin: ["http://localhost:3000"],
    credentials: true,

  app.listen(port, host, () => {
    consola.success(`API server listening on http://${host}:${port}`);
  1. Export the Endpoints interface as SapccEndpoints from the server/types.d.ts file. This interface contains the endpoints for the SAPCC integration that are going to be used in the SDK.
// server/types.d.ts

export { Endpoints as SapccEndpoints } from "@vsf-enterprise/sapcc-api";
  1. Let's setup a script to run the server middleware. Add the following script to your package.json file.
  "scripts": {
    "dev": "ts-node-dev src/index.ts"
  1. Run the server middleware.
yarn dev

Your server middleware is now running on http://localhost:8181 and SAPCC endpoints are available on http://localhost:8181/sapcc.

SDK preparation

Next, we need to prepare the SDK. The SDK is a package that is used to communicate with the server middleware.

Key concept - SDK

You can learn more in-depth about SDK in the Alokai SDK documentation.

Based on your project setup, you can use the SDK in three different ways. Please select the one that fits your project.


Next.js SDK module is based on the Alokai SDK Core. In order to use the Next.js SDK module, first you need to install the SDK Core.

SDK Core
# Using yarn
yarn add @vue-storefront/sdk

# Using npm
npm install @vue-storefront/sdk

# Using pnpm
pnpm install @vue-storefront/sdk

Once SDK Core is installed, you can proceed to install Next.js SDK module. Enter the command below in the root of your project to install Next.js SDK module:

# Using yarn
yarn add --dev @vue-storefront/next

# Using pnpm
pnpm add -D @vue-storefront/next

# Using npm
npm install --save-dev @vue-storefront/next

Initializing the SDK

To use the SDK in our application, we need to initialize it first. To do so, follow these steps:

  1. Create SDK Config file - sdk.config.ts in root directory of your project.

It is not necessary to name the file sdk.config.ts specifically or to keep it in the root of your project, but it is recommended to keep it consistent with the rest of the Alokai project.

  1. Create the SDK configuration by importing the createSdk function from the Next.js SDK and the modules you want to use.
import { CreateSdkOptions, createSdk } from "@vue-storefront/next";
import { SapccEndpoints } from "../server/types";

const options: CreateSdkOptions = {
  middleware: {
    apiUrl: "http://localhost:8181",

export const { getSdk, createSdkContext } = createSdk(
  ({ buildModule, middlewareUrl, middlewareModule, getRequestHeaders }) => ({
    sapcc: buildModule(middlewareModule<SapccEndpoints>, {
      apiUrl: middlewareUrl + "/sapcc",
      defaultRequestConfig: {
        headers: getRequestHeaders(),

Let's break down the code above:

  • The createSdk function expects
    • base SDK options including the middleware and (optionally) the multistore configuration as a first argument,
    • and a factory function for the SDK configuration as a second argument. Those factory function receives a context, useful for creating the SDK configuration.
  • The buildModule function is used to build the module. It expects the module and the module configuration as arguments.
  • The middlewareUrl is the URL of the middleware instance.
  • The getRequestHeaders function is used to retrieve the Cookie header with cookie values.
  • The createSdk function returns
    • the getSdk function, which is used to create the new SDK instance,
    • and the createSdkContext function, which is used to create the SDK context, to share the same SDK instance on the Client side.

Registering the SDK

Once you have initialized the SDK, you can register it in your application.

Alokai SDK can be used in two ways:

  • getSdk - returns the SDK instance, which can be used to call the SDK methods directly. This is useful for server-side rendering, as it allows you to call the SDK methods directly in your application.
  • createSdkContext - returns the SDK context, which can be used to share the same SDK instance on the Client side. This is useful for client-side rendering, as it allows you to share the same SDK instance across your application.


getSdk is used to create the new SDK instance. This is especially useful for server-side fetching, as it returns a new SDK instance that can be used to call the SDK methods directly in your application.

Below is an example of how you can use getSdk in your application:

import { getSdk } from "../sdk.config";

const sdk = getSdk();


For client-side rendering, you can use createSdkContext. In order to use it, you'll need to create a new file in your application, for example hooks/sdk.ts:

import { createSdkContext } from "@vue-storefront/next/client";
import { getSdk } from "../sdk.config";

export const [SdkProvider, useSdk] = createSdkContext(getSdk());

Once you have created the SDK context, you can register it in your application. For example, if you're using the Pages Router, you can register it in pages/_app.tsx:

import type { AppProps } from "next/app";
import { SdkProvider } from "../hooks";

export default function App({ Component, pageProps }: AppProps) {
  return (
      <Component {...pageProps} />

If you're using the App Router, you can register it in app/layout.tsx:

import { ReactNode } from "react";
import { Providers } from "./providers";

export default function RootLayout({ children }: { children: ReactNode }) {
  return (
    <html lang="en">
"use client";

import { ReactNode } from "react";
import { SdkProvider } from "../hooks";

export function Providers({ children }: { children: ReactNode }) {
  return <SdkProvider>{children}</SdkProvider>;

Don't be alarmed if you see a use client directive in the app/providers.tsx file. This will not turn your application into a client-side rendered application. All children inside the provider will be still rendered on the server-side by default. You can read more about use client directive in React Documentation.


Once you have registered the SDK in your application, you can start using it. Here's an example of how you can use the SAP Commerce Cloud SDK module in your application:

Pages Router
import { getSdk } from "../sdk.config";

export function getServersideProps() {
  const sdk = getSdk();
  const { products } = await sdk.sapcc.searchProduct();

  return {
    props: {

For more information about the available methods, please refer to the respective Integration's documentation.

That's it! You can now use Alokai SDK Module in your Next.js app ✨
