From e006fe78914ad73f026cf199f8e872abbb90cda8 Mon Sep 17 00:00:00 2001 From: dylandepass Date: Thu, 16 Jul 2026 11:23:20 -0400 Subject: [PATCH 1/3] fix(pdp): redirect to cart page on mobile after edge add-to-cart MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit On mobile the header cart badge update is too subtle — users don't notice the item was added and mash the button. After a successful edge-checkout add-to-cart on viewports < 900px, redirect to the cart page. Adds Cart.flush() to force a synchronous localStorage write before the redirect, avoiding a race where the debounced persist (300ms) hasn't fired yet. --- blocks/pdp/add-to-cart.js | 21 +++++++++++++++++---- scripts/cart.js | 8 ++++++++ tests/unit/cart.test.js | 13 +++++++++++++ tests/unit/mocks/scripts.mjs | 10 ++++++++++ 4 files changed, 48 insertions(+), 4 deletions(-) diff --git a/blocks/pdp/add-to-cart.js b/blocks/pdp/add-to-cart.js index b76069a5..105dcaef 100644 --- a/blocks/pdp/add-to-cart.js +++ b/blocks/pdp/add-to-cart.js @@ -1,5 +1,7 @@ import { getMetadata } from '../../scripts/aem.js'; -import { checkVariantOutOfStock, getLocaleAndLanguage, getPdpOverride } from '../../scripts/scripts.js'; +import { + checkVariantOutOfStock, getLocaleAndLanguage, getOrderPath, getPdpOverride, +} from '../../scripts/scripts.js'; import { getConfig } from '../../scripts/commerce-config.js'; import { logOperation, logError } from '../../scripts/operations-log.js'; @@ -389,11 +391,22 @@ export default function renderAddToCart(ph, block, parent) { }); } - // reenable button - addToCartButton.textContent = 'Add to Cart'; - addToCartButton.removeAttribute('aria-disabled'); logOperation('added-to-cart', { sku: targetSku, quantity: allowedQty }); document.dispatchEvent(new CustomEvent('pdp:add-to-cart', { detail: { item } })); + + // On mobile the header cart badge is too subtle — redirect to the + // cart page so the user gets clear feedback that the item was added. + // Flush first: addItem uses a debounced persist (300 ms) so + // localStorage may not have the new item yet. + if (window.innerWidth < 900) { + cartApi.flush(); + window.location.href = getOrderPath('cart'); + return; + } + + // reenable button (desktop only — mobile redirects above) + addToCartButton.textContent = 'Add to Cart'; + addToCartButton.removeAttribute('aria-disabled'); return; } diff --git a/scripts/cart.js b/scripts/cart.js index ac1d8c87..07258cd6 100644 --- a/scripts/cart.js +++ b/scripts/cart.js @@ -82,6 +82,14 @@ export class Cart { } } + /** + * Flush any debounced writes to localStorage immediately.
