BigCommerce Storefront Data Hooks

This project is under active development, new features and updates will be continuously added over time

UI hooks and data fetching methods built from the ground up for e-commerce applications written in React, that use BigCommerce as a headless e-commerce platform. The package provides:

• Code splitted hooks for data fetching using SWR, and to handle common user actions
• Code splitted data fetching methods for initial data population and static generation of content
• Helpers to create the API endpoints that connect to the hooks, very well suited for Next.js applications

Installation

To install:

yarn add @bigcommerce/storefront-data-hooks

After install, the first thing you do is: set your environment variables in .env.local

BIGCOMMERCE_CHANNEL_ID=
BIGCOMMERCE_STOREFRONT_API_TOKEN=
BIGCOMMERCE_STOREFRONT_API_URL=
BIGCOMMERCE_STORE_API_CLIENT_ID=
BIGCOMMERCE_STORE_API_TOKEN=
BIGCOMMERCE_STORE_API_URL=
BIGCOMMERCE_STORE_HASH=
SECRET_COOKIE_PASSWORD=

General Usage

CommerceProvider

This component is a provider pattern component that creates commerce context for it's children. It takes config values for the locale and an optional fetcherRef object for data fetching.

...
import { CommerceProvider } from '@bigcommerce/storefront-data-hooks'

const App = ({ locale = 'en-US', children }) => {
  return (
    <CommerceProvider locale={locale}>
      {children}
    </CommerceProvider>
  )
}
...

useLogin hook

Hook for bigcommerce user login functionality, returns login function to handle user login.

...
import useLogin from '@bigcommerce/storefront-data-hooks/use-login'

const LoginView = () => {
  const login = useLogin()

  const handleLogin = async () => {
    await login({
      email,
      password,
    })
  }

  return (
    <form onSubmit={handleLogin}>
      {children}
    </form>
  )
}
...

Login SSO

To authenticate a user using the Customer Login API, it's necessary to point the useLogin hook to your own authentication endpoint.

const login = useLogin({
  options: {
    url: '/api/your-own-authentication'
  },
})

That authentication endpoint have to return a Set-Cookie header with SHOP_TOKEN=your_customer_authentication_token. See an example.

import useLogout from '@bigcommerce/storefront-data-hooks/use-logout'

const LogoutLink = () => {
  const logout = useLogout()
  return (
    <a onClick={() => logout()}>
      Logout
    </a>
  )
}

useCustomer

...
import useCustomer from '@bigcommerce/storefront-data-hooks/use-customer'
...

const Profile = () => {
  const { data } = useCustomer()

    return null
  }

  return (
    <div>Hello, {data.firstName}</div>
  )
}

useSignup

Hook for bigcommerce user signup, returns signup function to handle user signups.

...
import useSignup from '@bigcommerce/storefront-data-hooks/use-signup'

    }
  )

  const itemInWishlist = data?.items?.find(
    (item) =>
      item.product_id === productId &&
      item.variant_id === variant?.node.entityId
  )

  const handleWishlistChange = async (e) => {
    e.preventDefault()

    if (!customer) {
      return
    }

    if (itemInWishlist) {
      await removeItem({ id: itemInWishlist.id! })
    } else {
      await addItem({
        productId,
        variantId: variant?.node.entityId!,
      })

Checkout

The checkout only works on production and with a custom domain

The recommended method is the Embedded Checkout, follow the tutorial to create a channel and a site. Notes:

• The channel should be of type storefront
• The site url must be your production url (e.g: https://mystorefront.com)
• This package takes care of the cart and redirect links creation
• Your bigcommerce storefront must be a subdomain of your headless storefront (eg: https://bc.mystorefront.com)

Troubleshooting

The useSignup hooks tries to login the user after creating it. Probably you have an error with the login. Checkout that your have your store Open since if the store is Down for Maintenance the users can't login.

Thanks @Strapazzon 🚀

Configuration

You will need to crate a .env file from the .env.example with the following keys.

• BIGCOMMERCE_STOREFRONT_API_TOKEN
• BIGCOMMERCE_STOREFRONT_API_URL

The token and url will be crated in your BC Store admin section: Advanced Settings -> API Accounts. Once you have added the .env configuration, run:

• yarn generate to generate your new schema.
• yarn build to build a new set of compiled files.

Link the package locally to your app with yarn link or by using the YALC tool.
