use the context in component

Use the context of the Snipcart plugin. You have 2 values in the context :

  • state (object of value)
  • changeLanguage (function)

When you use the changeLanguage function, it use the locales string define in config of plugin.

import { SnipcartContext } from "gatsby-plugin-snipcart-advanced/context";

const { state, changeLanguage } = useContext(SnipcartContext);

changeLanguage("en");

Example of component:

import { SnipcartContext } from "gatsby-plugin-snipcart-advanced/context";

const MyComponent = () => {
  const { state } = useContext(SnipcartContext);
  const { userStatus, cartQuantity } = state;
  return (
    <div>
      {userStatus === "SignedOut" ? (
        <button className="snipcart-customer-signin">
          <span>Se connecter</span>
        </button>
      ) : (
        <button className="snipcart-customer-signin">
          <span>Mon compte</span>
        </button>
      )}
      <button className="snipcart-checkout">
        <span>{cartQuantity}</span>
      </button>
    </div>
  );
};

Usage of snipcart for add a product in cart

The values come from where you want : markdown files, api…

Example of button for your product component:

<button
  className="snipcart-add-item"
  data-item-id={id}
  data-item-price={price}
  data-item-url={slug}
  data-item-description={product.excerpt}
  data-item-image={image && image.publicURL}
  data-item-name={title}
  data-item-quantity="1"
  data-item-taxes={tva}
  disabled={_stock === 0 ? true : false}
>
  Add to cart
</button>

Example of component for display a dialog alert after click on “Add to cart” button (if you set “openCartOnAdd” to false)

import styles from "./styles.module.css";

const AddCartModal = () => {
  const [open, toggleOpen] = useState(false);
  const [item, setItem] = useState({});
  // hidden button for open the cart
  const bt_cart = useRef();
  // mask under modal
  const mask = useRef();
  useEffect(() => {
    const { Snipcart } = window;
    if (!Snipcart) return;
    // open modal on snipcart event add item on cart
    Snipcart.events.on("item.adding", (_item) => {
      setItem(_item);
      toggleOpen(true);
    });
  }, []);

  return (
    <>
      <div
        ref={mask}
        className={`${open === true ? styles.show : ""} ${styles.mask}`}
      >
        <div className={styles.add__cart} role="alertdialog">
          <button className={styles.close} onClick={() => toggleOpen(false)}>
            <span>Close</span>
          </button>
          <div className={styles.confirm}>
            {item.name && (
              <span>
                <strong>
                  {item.quantity} {item.name}
                </strong>{" "}
                {"added to your cart"}
              </span>
            )}
          </div>
          <div className={styles.actions}>
            <button onClick={() => toggleOpen(false)}>
              Continuer les achats
            </button>
            <button
              className={styles.got_cart}
              onClick={() => {
                toggleOpen(false);
                bt_cart.current.click();
              }}
            >
              Voir le panier
            </button>
          </div>
        </div>
      </div>
      <button
        ref={bt_cart}
        style={{ height: 0, opacity: 0 }}
        className="snipcart-checkout"
      ></button>
    </>
  );
