Why Bagisto Headless?
Integrating the Bagisto GraphQL API with Next.js allows you to build modern, scalable, and high-performance e-commerce storefronts. This document outlines the core advantages of this decoupled architecture.
1.1 The Decoupled Advantage
Bagisto Headless separates the frontend experience from the commerce engine, providing absolute flexibility for developers and businesses.
Roles & Responsibilities
| Component | Responsibility |
|---|---|
| Bagisto Core | Managing products, inventory, customers, orders, payments, and shipping logic. |
| Next.js | Handling the UI/UX, page rendering, routing, SEO, and client-side interactions. |
NOTE
This separation allows you to scale your frontend and backend independently. You can update your storefront's design without ever touching the core commerce logic.
1.2 Powerful API Layer: GraphQL
Bagisto's GraphQL API is the perfect bridge for headless commerce, offering superior efficiency over traditional REST APIs.
Key Advantages
- Precise Data Fetching: Request exactly what you need—no more, no less.
- Single Endpoint: Simplified communication via
/graphql. - Strongly Typed Schema: Robust tooling and fewer runtime errors with schema-first development.
- Efficiency: Fetch complex, nested data (like products with their reviews and variants) in a single query.

1.3 High-Performance Storefront: Next.js
Next.js provides the production-ready infrastructure needed to build e-commerce sites that convert users into customers.
Key Advantages
- Hybrid Rendering: Choose the best strategy for every page (SSR, SSG, or ISR).
- SEO Dominance: Pre-rendered HTML ensures your products rank high in search results.
- Advanced Optimizations: Built-in code splitting, image optimization, and font loading out of the box.
- Developer Experience: TypeScript support, fast refresh, and an intuitive file-based routing system.

1.4 Architecture & Data Flow
How It Works
- User Interaction: A user requests a page (e.g., a specific category or product).
- Strategy Selection: Next.js determines the rendering strategy (e.g., ISR for product pages).
- Data Retrieval: A GraphQL query is sent from Next.js to the Bagisto backend.
- Resolution: Bagisto processes the business logic and returns a structured JSON response.
- Rendering & Hydration: Next.js renders the HTML server-side or at build-time, and React hydrates it for full interactivity in the browser.
1.5 Optimized Rendering Strategies
E-commerce requires a mix of speed and real-time data. This stack handles both:
| Strategy | Best For | Benefit |
|---|---|---|
| SSR | Cart, Checkout, Profile | Real-time, secure, and personalized content. |
| SSG | Homepage, About, CMS | Lightning-fast loads and maximum SEO. |
| ISR | Product Pages, Lists | Static speed with background updates for price/stock. |
