React, Vite and Supabase for D2C: Architecture Decisions
A custom D2C stack can provide control over storefront behavior and integrations, but it also creates responsibility for security, payments and operations. Choose it when those requirements justify maintaining a custom system.
What to do first
Separate public catalog access from protected customer, order and administrative data.
Implementation and review
- Use a server-controlled payment workflow and verify payment-provider callbacks before marking an order paid.
- Plan stock handling, order support, monitoring and deployment recovery before launch.
What to watch for
Never trust a client-side payment success screen as proof of payment. A custom stack is not automatically cheaper than Shopify.
A practical example to work through
Keep price and payment decisions on a trusted backend rather than accepting the browser's claimed amount. Record order state changes so repeated callbacks do not create duplicate fulfillment. Test what happens when a payment is pending or a customer closes the page. These operational states are part of the storefront's quality, even when they are invisible in the marketing mockup.
