Add an install prompt to BigCommerce
To add an install prompt on BigCommerce, paste the InstantPWA snippet into Script Manager via Storefront → Script Manager → Create a Script. The popup captures the browser's native install signal where supported and falls back to a guided walkthrough on iOS Safari, so every visitor sees a clear path to installing your BigCommerce site as an app.
Steps
- 1
Open Script Manager
Go to Storefront → Script Manager → Create a Script.
- 2
Paste the InstantPWA snippet
Drop the one-line async script tag in the BigCommerce head section — no build step or dependency install.
- 3
Configure the trigger
In your InstantPWA dashboard, set when the popup appears — on page load, after N seconds, or after a scroll/engagement threshold.
- 4
Publish
Save/publish in BigCommerce so the change goes live — most builders require an explicit publish step before custom code runs.
- 5
Verify on a phone
Open your live BigCommerce URL on a mobile device (not the editor preview) to confirm the popup renders.
Constraints to know
- Script Manager is available on every BigCommerce plan including trial stores, and survives theme changes since it's decoupled from Stencil template files.
- Catalyst (headless, Next.js-based) storefronts don't render Stencil-injected scripts — use the Next.js install guide instead for Catalyst stores.
FAQ
Does the install prompt work on iOS BigCommerce visitors?+
iOS Safari never fires the native beforeinstallprompt event, so InstantPWA shows a share-sheet walkthrough instead — visitors still get a clear add-to-home-screen path.
Will this conflict with other scripts on my site?+
No — InstantPWA is a single first-party async script with no third-party dependencies, so it doesn't block or compete with analytics or chat widgets.
Do I need to touch anything else in BigCommerce besides Storefront?+
No — the head snippet is the only integration point; InstantPWA hosts the manifest and service worker for you.
