Build an E-Commerce Web App with Paystack, NextJS, Supabase
Why It Matters
The tutorial empowers African startups and global developers to launch secure, scalable e‑commerce sites quickly, using a cost‑effective stack that replaces Stripe with Paystack and eliminates heavy backend development.
Key Takeaways
- •Combine Next.js, Supabase, Zustand, Paystack for full‑stack e‑commerce.
- •Use Supabase storage and RLS policies to secure product images.
- •Implement Paystack API for African‑focused payment processing seamlessly.
- •Persist state with Zustand and validate data using Zod schemas.
- •Deploy the finished app on Vercel and monitor logs via dashboard.
Summary
The video walks viewers through building a complete e‑commerce web application using a modern stack: Next.js for the front‑end, Supabase as a backend‑as‑a‑service, Zustand for state management, and Paystack for payments. It emphasizes TypeScript‑driven development, Next.js file‑system routing, and API route creation, while also showing how to integrate Supabase storage and role‑level security (RLS) policies for product images.
Key technical steps include importing assets, configuring a public Supabase bucket, writing SQL to create user and product tables, and using Zod for schema validation. The tutorial demonstrates Paystack’s simple API by processing a test payment of 35,900 Naira, verifying the transaction, and displaying the order in a user‑specific order page. State persistence challenges with Zustand are addressed, and the entire project is version‑controlled on GitHub and deployed to Vercel, with a walkthrough of environment variables, logs, and deployment settings.
The presenter highlights practical examples such as clicking “Buy Now,” being redirected to login, selecting an address, and completing payment via Paystack. Screenshots of the live site (ldstore.vercel.app) show product listings, cart functionality, and order tracking. The Figma design file is shared for UI reference, and the Supabase bucket creation process is detailed, including policy templates for controlling image access.
For developers, the tutorial showcases a repeatable, production‑ready workflow that leverages serverless infrastructure and a payment gateway tailored to African markets. By combining these tools, teams can accelerate time‑to‑market, reduce reliance on custom back‑ends, and tap into Paystack’s regional payment ecosystem, positioning the stack as a compelling alternative to traditional e‑commerce solutions.
