This package contains methods providing Saleor business logic for a storefront and apps. It handles Saleor GraphQL queries and mutations, manages Apollo cache, and provides an internal state to manage popular storefront use cases, like user authentication.

⚠️ Note: Saleor SDK is DEPRECATED. See the announcement.

For authentication, follow the Saleor docs and use @saleor/auth-sdk.

• Setup
• Features
• Local development

There are two ways to use SDK - making custom implementation or using React components and hooks, which already has that implementation ready.

First install following dependencies to your project

npm install @saleor/sdk @apollo/client graphql

Use SaleorProvider with passed Saleor's client created by createSaleorClient in a prop. Then use React hooks in any component passed as child to SaleorProvider.

import {
  SaleorProvider,
  createSaleorClient,
  useAuth,
  useAuthState,
} from "@saleor/sdk";

const client = createSaleorClient({
  apiUrl: "<SALEOR_GRAPHQL_URL>",
  channel: "<CHANNEL>",
});

const rootElement = document.getElementById("root");
ReactDOM.render(
  <SaleorProvider client={client}>
    <App />
  </SaleorProvider>,
  rootElement
);

const App = () => {
  const { login } = useAuth();
  const { authenticated, user, authenticating } = useAuthState();

  const handleSignIn = async () => {
    const { data } = await login({
      email: "admin@example.com",
      password: "admin",
    });

    if (data.tokenCreate.errors.length > 0) {
      /**
       * Unable to sign in.
       **/
    } else if (data) {
      /**
       * User signed in successfully.
       **/
    }
  };

  // Important: wait till the authentication process finishes
  if (authenticating) {
    return <div>Loading...</div>
  }

  if (authenticated && user) {
    return <span>Signed in as {user.email}</span>;
  }

  return <button onClick={handleSignIn}>Sign in</button>;
};

npm install @saleor/sdk @apollo/client graphql

Then use createSaleorClient to get Saleor api methods and internal config variables like channel and Apollo client.

import { createSaleorClient } from "@saleor/sdk";

const client = createSaleorClient({
  apiUrl: "<SALEOR_GRAPHQL_URL>",
  channel: "<CHANNEL>",
});

const { auth, config, _internal } = client;

Finally, API methods can be used:

const { data } = await auth.login({
  email: "admin@example.com",
  password: "admin",
});

if (data.tokenCreate.errors.length > 0) {
  /**
   * Unable to sign in.
   **/
} else if (data) {
  /**
   * User signed in successfully.
   **/
  const userData = api.auth.tokenCreate.user;
}

SDK provides fetch method with all the necessary authorization headers assigned to HTTP requests and handled authorization token creation, verification and refresh inside, which you may use instead of built-in browser fetch. Using SDK auth login or logout methods will appropriately alter fetch behavior automatically, like including Authorization Bearer header in HTTP request.

import { createFetch } from "@saleor/sdk";

const authorizedFetch = createFetch();

const result = await authorizedFetch("https://example.com");

If you use GraphQL you may pass SDK fetch to the Apollo client:

const authorizationLink = new HttpLink({
  fetch: authorizedFetch,
});
const apolloClient = new ApolloClient({
  link: authorizationLink,
});

SDK fetch method uses cross-fetch under the hood.

We provide an API with methods and fields, performing one, scoped type of work. You may access them straight from createSaleorClient() or use React hooks:

SDK supports OpenId Connect methods provided by Saleor API. They are under auth object and useAuth hook. For more usage details, please check https://docs.saleor.io/docs/3.0/developer/available-plugins/openid-connect.

Our aim it to build SDK, highly configurable, as a separate package, which you will not require modifications. Although if you want to alter the project, especially if you want to contribute, it is possible to develop storefront and SDK simultaneously. To do this, you need to link it to the storefront's project.

$ cd lib
$ npm link
$ cd <your storefront path>
$ npm link @saleor/sdk

Notice that in our example storefront webpack is configured to always resolve react to ./node_modules/react. It may seem redundant for the most use cases, but helps in sdk's local development, because it overcomes npm's limitations regarding peer dependencies hoisting, explicitly telling webpack to always have one and only copy of react.

Set environment variables:

export API_URI=https://your.saleor.instance.com/graphql/
export TEST_AUTH_EMAIL=admin@example.com
export TEST_AUTH_PASSWORD=admin

1. Download repository
2. Install dependencies: npm i
3. Now you can start files watcher with: npm run start

npm run build

Tests are located at /test directory. To start the test suite:

npm run test

All communication with API is prerecorded using Polly.JS. Unless requests changed or code executes new ones, no requests to API will be made.

Changes in /recordings directory should be reviewed before committing to make sure that changes in communication are intentional.

The project has configured Prettier and ESLint. To check your code:

npm run lint

npm run download-schema

Command will overwrite introspection.json with server schema, based on API_URL variable.

GraphQL Code Generator is an automatic tool that converts schema to TS types. After changing schema file run:

npm run build-types

Changes in the core user methods and tests may result in failing tests. Typically you may encounter the following error:

request to http://localhost:8000/graphql/ failed, reason: connect ECONNREFUSED 127.0.0.1:8000

To fix this run npm run test with the following variables:

• API_URI
• TEST_AUTH_EMAIL
• TEST_AUTH_PASSWORD

After the tests run the recordings should be updated. Next time you run tests without variables, tests will use updated recordings.
