Multisite application in Rails (like shopify.com)

Shopify Discussion

Topic summary

The post outlines a technical architecture for building a multisite Rails application similar to Shopify, where multiple independent stores share a common codebase.

Core Architecture:

  • Implement multitenancy using gems like Apartment or ActsAsTenant
  • Choose between separate databases per site, shared schema with tenant identifiers, or hybrid approach
  • Configure dynamic subdomains for each store

Key Features to Implement:

  • User authentication/authorization ensuring store owners only access their own data
  • Store-specific configuration management (using RailsSettings or dedicated tables)
  • Custom layouts and theming system allowing each store to customize appearance
  • Product and inventory management tied to specific stores
  • Per-store payment processing integration (Stripe, Braintree)
  • SEO-friendly URLs and customizable metadata per store

Technical Considerations:

  • Maintain shared codebase using modules, concerns, or service objects
  • Implement monitoring and analytics to track individual store performance
  • Write tests ensuring shared codebase changes don’t negatively impact individual stores
  • Plan for scaling through database optimization, caching strategies, and background processing
  • Consider Docker or cloud services for isolated, scalable deployment environments

Creating a multisite application in Rails, similar to Shopify, involves designing a system where multiple independent websites (or stores) share a common codebase but have their own distinct data, configurations, and possibly layouts. Here’s a high-level overview of how you might approach building a multisite application in Rails:

1. Setup a Multitenancy Architecture:- Choose a multitenancy strategy: You can opt for a separate database per site, shared schema with tenant identifiers, or a hybrid approach.

  • Consider using gems like Apartment or ActsAsTenant to handle multitenancy aspects.

2. User Authentication and Authorization:- Implement user authentication to allow users (store owners) to log in and manage their respective sites.

  • Ensure that each user has the right permissions to modify only their own site’s data.

3. Store Configuration:- Create a model for site configuration that allows each store to have its own settings.

  • Consider using a gem like RailsSettings or managing configuration through a dedicated table.

4. Dynamic Subdomains:- Configure your application to use dynamic subdomains for each site. This could involve using the Apartment gem or custom subdomain handling in routes.

  • 5. Shared Codebase:- Keep the common functionality shared across all sites in a central codebase.

    • Use modules, concerns, or service objects to isolate site-specific functionality.### 6. Custom Layouts and Theming:- Allow each store to have its own layout and theme.
    • Use a solution like RailsThemes or create a system where each store can customize its view templates.### 7. Product and Inventory Management:- Implement product and inventory management features.
    • Associate products with specific stores and manage inventory independently.### 8. Order and Payment Processing:- Manage orders and payments on a per-store basis.
    • Consider using a gem like Stripe or Braintree for payment processing.### 9. SEO Considerations:- Implement SEO-friendly URLs for each store.
    • Ensure that metadata and other SEO elements can be customized per store.### 10. Testing and Deployment:- Write tests to ensure that changes to the shared codebase don’t negatively impact individual stores.
    • Consider using tools like Docker for deployment or cloud services that support scalable and isolated environments.### 11. Monitoring and Analytics:- Implement monitoring and analytics to track the performance of each store independently.
    • Use tools like New Relic, Google Analytics, or custom logging for insights.### 12. Scaling Considerations:- Plan for scaling as the number of stores grows. This may involve optimizing database queries, using caching strategies, and considering background processing for task.
