Part 33: Building a Shop with Next.js: Planning Your Architecture
[Pages] Next Shop: Setup
As we embark on creating our new online shop with Next.js, it's crucial to plan the architecture before diving into the code. Our goal is to establish a robust system that can handle our data needs and scale efficiently. Let's explore the high-level architecture considerations for our shop application.
Understanding Our Data Needs
The foundation of our application will be its data. To effectively run an online shop, we need to manage several key data entities:
Products: This is the core data entity. Each product will have attributes such as name, description, price, and more, which are crucial for displaying and selling items on our website.
Users: These are our customers. We need to store user information to facilitate logins, manage profiles, and handle delivery details.
Shopping Cart: This is a dynamic entity where users can add products they wish to purchase. It connects users with products, making it an essential part of the shopping experience.
While these are the primary data components, we might also need data related to orders and payments. However, for simplicity, we'll assume a third-party service handles these aspects.
Choosing a Storage Solution
For our shop, using a local file system for storing data—as we did in our earlier blog project—is not feasible. The need to frequently update user and cart data would make file-based storage cumbersome and inefficient. Instead, we'll opt for a database.
Database Options
Relational Databases: Such as MySQL or PostgreSQL, which are great for structured data and enforcing relationships.
NoSQL Databases: Like MongoDB, which offer flexibility for unstructured or semi-structured data.
Both options provide scalable solutions for handling large datasets and managing relationships, such as linking a shopping cart to a user.
Introducing a Backend Layer
Directly connecting the Next.js app to a database can work in simple scenarios. However, for a more scalable and flexible solution, introducing a backend layer is beneficial. This layer can serve as an intermediary, handling all interactions with the database.
Benefits of a Backend API
Decoupling Frontend and Database: The frontend only needs to interact with the backend API, abstracting away the database specifics.
Reusable API: The backend API can serve other clients, such as mobile apps, allowing for expanded accessibility.
Security and Logic: Centralizing data processing and business logic in the backend enhances security and maintainability.
Utilizing a Headless CMS
Rather than building a backend from scratch, we can leverage a Headless CMS. This approach provides us with an API for managing content, along with an admin interface for non-developers to manage data.
Advantages of a Headless CMS
Content Management: Administrators can easily update product details through a user-friendly interface.
Focus on Frontend: Developers can concentrate on building the customer-facing aspects of the site, without worrying about backend content management.
Flexibility: Headless CMSes can integrate with various frontends, providing adaptability for future expansions.
Selecting a Headless CMS
There are numerous headless CMS options available, each with its own strengths. While many are cloud-based proprietary solutions, there are open-source options like Strapi, which we will use for our shop. Strapi allows you to host your data locally, offering flexibility and control over your content.
Conclusion
In planning the architecture for our Next.js shop, we've outlined a strategy that leverages a headless CMS for efficient content management and scalability. This approach allows us to focus on delivering a seamless shopping experience for our users while maintaining flexibility for future growth. As we move forward, we'll explore the specifics of integrating Strapi with our Next.js application. Stay tuned for more insights as we continue building our shop!
