This package contains methods providing Saleor business logic for storefront. It handles Saleor GraphQL queries and mutations, manages Apollo cache and provides internal state to manage popular storefront use cases, like user authentication or checkout process.
Please take a look at sample storefront which already uses Saleor SDK. For specific use cases you may also refer to saleor-sdk/examples.
⚠️ Note: Saleor SDK is still under heavy development and its API may change.
There are two ways to use SDK - making custom implementation or using React components and hooks, which already has that implementation ready.
First install SDK as dependency to your project
npm install @saleor/sdk
Use SaleorProvider
with passed custom config in a prop. Then use React hooks in any component passed as child to SaleorProvider
.
import { SaleorProvider, useAuth } from "@saleor/sdk";
const config = { apiUrl: "http://localhost:8000/graphql/", channel: "" };
const apolloConfig = {
/*
Optional custom Apollo client config.
Here you may append custom Apollo cache, links or the whole client.
You may also use import { createSaleorCache, createSaleorClient, createSaleorLinks } from "@saleor/sdk" to create semi-custom implementation of Apollo.
*/
};
const rootElement = document.getElementById("root");
ReactDOM.render(
<SaleorProvider config={config} apolloConfig={apolloConfig}>
<App />
</SaleorProvider>,
rootElement
);
const App = () => {
const { authenticated, user, signIn } = useAuth();
const handleSignIn = async () => {
const { data, dataError } = await signIn("admin@example.com", "admin");
if (dataError) {
/**
* Unable to sign in.
**/
} else if (data) {
/**
* User signed in successfully.
**/
}
};
if (authenticated && user) {
return <span>Signed in as {user.firstName}</span>;
} else {
return <button onClick={handleSignIn}>Sign in</button>;
}
};
npm install @saleor/sdk
Then use SaleorManager to get SaleorAPI
from connect
method. This method may also take optional function as an argument, which will be executed every time the SaleorAPI
state changes.
const config = { apiUrl: "http://localhost:8000/graphql/", channel: "" };
const apolloConfig = {
/*
Optional custom Apollo client config.
Here you may append custom Apollo cache, links or the whole client.
You may also use import { createSaleorCache, createSaleorClient, createSaleorLinks } from "@saleor/sdk" to create semi-custom implementation of Apollo.
*/
};
const manager = new SaleorManager(config, apolloConfig);
const { api, apolloClient } = await manager.connect(saleorAPI => {
/* Optional listener to API state change. You may use it to update your app state reactively - e.g. trigger the React context update. */
});
Finally, methods from api
might be used:
const { data, dataError } = await api.auth.signIn("admin@example.com", "admin");
if (dataError) {
/**
* Unable to sign in.
**/
} else if (data) {
/**
* User signed in successfully. Read user object from data or from api.auth.
**/
const userData = api.auth.user;
}
We provide an API with methods and fields, performing one, scoped type of work. You may access them straight from SaleorAPI
or use React hooks, depending on which setup do you select.
API object | React hook | Description |
---|---|---|
SaleorAPI.auth |
useAuth() |
Handles user authentication and stores data about the currently signed in user. |
SaleorAPI.cart |
useCart() |
Collects products to cart and calculates their prices. |
SaleorAPI.checkout |
useCheckout() |
Uses cart and handles the whole checkout process. |
SaleorAPI.products |
useProductDetails() , useProductList() |
Obtains products. |
SaleorAPI.collections |
useCollectionDetails() , useCollectionList() |
Obtains collections. |
SaleorAPI.categories |
useCategoryDetails() , useCategoryList() , useCategoryAncestorsList() , useCategoryChildrenList() |
Obtains categories. |
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
.
