# BigCommerce Storefront Data Hooks ## Usage
> This project is under active development, new features and updates will be continuously added over time As this is still under development, no npm package is yet provided. Here's how you can try it out:
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: 1. First you'll need a Vendure server. You can your own local server up-and-running with just a single command:
```shell
- Code splitted hooks for data fetching using [SWR](https://swr.vercel.app/), and to handle common user actions npx @vendure/create my-app
- 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 See the [Vendure getting started guide](https://www.vendure.io/docs/getting-started/) for more info.
2. Once you have Vendure set up, change the default port to something other than 3000, to avoid conflict with your Next.js Commerce dev server:
## Installation ```TypeScript
// vendure-config.ts
To install: export const config: VendureConfig = {
apiOptions: {
``` port: 3001, // <----- here
yarn add storefront-data-hooks adminApiPath: 'admin-api',
``` // ...
After install, the first thing you do is: <b>set your environment variables</b> in `.env.local`
```sh
VENDURE_SHOP_API_URL=<>
```
## 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.
```jsx
...
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.
```jsx
...
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}> 3. Clone this repo and install its dependencies with `yarn install` or `npm install`
{children} 4. Change the paths in [tsconfig.json](../../tsconfig.json) to point to the Vendure hooks:
</form> ```diff
) "paths": {
} "@lib/*": ["lib/*"],
... "@assets/*": ["assets/*"],
``` "@config/*": ["config/*"],
"@components/*": ["components/*"],
### useLogout "@utils/*": ["utils/*"],
"@commerce/*": ["framework/commerce/*"],
Hook to logout user. "@commerce": ["framework/commerce"],
- "@framework/*": ["framework/bigcommerce/*"],
```jsx - "@framework": ["framework/bigcommerce"]
... + "@framework/*": ["framework/vendure/*"],
import useLogout from '@bigcommerce/storefront-data-hooks/use-logout' + "@framework": ["framework/vendure"]
const LogoutLink = () => {
const logout = useLogout()
return (
<a onClick={() => logout()}>
Logout
</a>
)
}
```
### useCustomer
Hook for getting logged in customer data, and fetching customer info.
```jsx
...
import useCustomer from '@bigcommerce/storefront-data-hooks/use-customer'
...
const Profile = () => {
const { data } = useCustomer()
if (!data) {
return null
} }
```
5. Set the Vendure Shop API URL in your `.env.local` file:
```sh
NEXT_PUBLIC_VENDURE_SHOP_API_URL=http://localhost:3001/shop-api
```
6. With the Vendure server running, start this project using `yarn dev` or `npm run dev`.
return ( ## Known Limitations
<div>Hello, {data.firstName}</div>
)
}
```
### useSignup 1. Vendure does not ship with built-in wishlist functionality.
2. Nor does it come with any kind of blog/page-building feature. Both of these can be created as Vendure plugins, however.
Hook for bigcommerce user signup, returns `signup` function to handle user signups. 3. The entire Vendure customer flow is carried out via its GraphQL API. This means that there is no external, pre-existing checkout flow. The checkout flow must be created as part of the Next.js app.
4. By default, the sign-up flow in Vendure uses email verification. This means that using the existing "sign up" flow from this project will not grant a new user the ability to authenticate, since the new account must first be verified. Again, the necessary parts to support this flow can be created as part of the Next.js app.
```jsx 5. The mapping of products & variants may not totally match up with what the storefront expects. As the storefront matures and improves this mapping can be refined.
...
import useSignup from '@bigcommerce/storefront-data-hooks/use-login'
const SignupView = () => {
const signup = useSignup()
const handleSignup = async () => {
await signup({
email,
firstName,
lastName,
password,
})
}
return (
<form onSubmit={handleSignup}>
{children}
</form>
)
}
...
```
### usePrice
Helper hook to format price according to commerce locale, and return discount if available.
```jsx
import usePrice from '@bigcommerce/storefront-data-hooks/use-price'
...
const { price, discount, basePrice } = usePrice(
data && {
amount: data.cart_amount,
currencyCode: data.currency.code,
}
)
...
```
## Cart Hooks
### useCart
Returns the current cart data for use
```jsx
...
import useCart from '@bigcommerce/storefront-data-hooks/cart/use-cart'
const countItem = (count: number, item: any) => count + item.quantity
const countItems = (count: number, items: any[]) =>
items.reduce(countItem, count)
const CartNumber = () => {
const { data } = useCart()
const itemsCount = Object.values(data?.line_items ?? {}).reduce(countItems, 0)
return itemsCount > 0 ? <span>{itemsCount}</span> : null
}
```
### useAddItem
```jsx
...
import useAddItem from '@bigcommerce/storefront-data-hooks/cart/use-add-item'
const AddToCartButton = ({ productId, variantId }) => {
const addItem = useAddItem()
const addToCart = async () => {
await addItem({
productId,
variantId,
})
}
return <button onClick={addToCart}>Add To Cart</button>
}
...
```
### useUpdateItem
```jsx
...
import useUpdateItem from '@bigcommerce/storefront-data-hooks/cart/use-update-item'
const CartItem = ({ item }) => {
const [quantity, setQuantity] = useState(item.quantity)
const updateItem = useUpdateItem(item)
const updateQuantity = async (e) => {
const val = e.target.value
await updateItem({ quantity: val })
}
return (
<input
type="number"
max={99}
min={0}
value={quantity}
onChange={updateQuantity}
/>
)
}
...
```
### useRemoveItem
Provided with a cartItemId, will remove an item from the cart:
```jsx
...
import useRemoveItem from '@bigcommerce/storefront-data-hooks/cart/use-remove-item'
const RemoveButton = ({ item }) => {
const removeItem = useRemoveItem()
const handleRemove = async () => {
await removeItem({ id: item.id })
}
return <button onClick={handleRemove}>Remove</button>
}
...
```
## Wishlist Hooks
Wishlist hooks are similar to cart hooks. See the below example for how to use `useWishlist`, `useAddItem`, and `useRemoveItem`.
```jsx
import useAddItem from '@bigcommerce/storefront-data-hooks/wishlist/use-add-item'
import useRemoveItem from '@bigcommerce/storefront-data-hooks/wishlist/use-remove-item'
import useWishlist from '@bigcommerce/storefront-data-hooks/wishlist/use-wishlist'
const WishlistButton = ({ productId, variant }) => {
const addItem = useAddItem()
const removeItem = useRemoveItem()
const { data } = useWishlist()
const { data: customer } = useCustomer()
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!,
})
}
}
return (
<button onClick={handleWishlistChange}>
<Heart fill={itemInWishlist ? 'var(--pink)' : 'none'} />
</button>
)
}
```
## Product Hooks and API
### useSearch
`useSearch` handles searching the bigcommerce storefront product catalog by catalog, brand, and query string.
```jsx
...
import useSearch from '@bigcommerce/storefront-data-hooks/products/use-search'
const SearchPage = ({ searchString, category, brand, sortStr }) => {
const { data } = useSearch({
search: searchString || '',
categoryId: category?.entityId,
brandId: brand?.entityId,
sort: sortStr || '',
})
return (
<Grid layout="normal">
{data.products.map(({ node }) => (
<ProductCard key={node.path} product={node} />
))}
</Grid>
)
}
```
### getAllProducts
API function to retrieve a product list.
```js
import { getConfig } from '@bigcommerce/storefront-data-hooks/api'
import getAllProducts from '@bigcommerce/storefront-data-hooks/api/operations/get-all-products'
const { products } = await getAllProducts({
variables: { field: 'featuredProducts', first: 6 },
config,
preview,
})
```
### getProduct
API product to retrieve a single product when provided with the product
slug string.
```js
import { getConfig } from '@bigcommerce/storefront-data-hooks/api'
import getProduct from '@bigcommerce/storefront-data-hooks/api/operations/get-product'
const { product } = await getProduct({
variables: { slug },
config,
preview,
})
```
