High-LevelArchitecture Decisions

The Bird's Eye View

When building Shopify stores, it's easy to get lost in the details - pixel-perfect designs, micro-interactions, individual feature requests. But stepping back to see the full picture often reveals the decisions that will matter most in six months or a year.


The Build vs. Buy Decision

For every feature, you have a choice: build it custom, use a Shopify app, or find a third-party service. Here's my framework:

Build Custom When:

  • The feature is core to your competitive advantage
  • No existing solution fits your exact workflow
  • You need complete control over data and performance

Use Apps When:

  • The problem is well-solved by the ecosystem
  • Speed to market matters more than customization
  • The app vendor has strong support and updates

Data Architecture Matters

How you structure your data in Shopify determines what's possible later:

Metafields: Use them liberally, but plan your namespaces. A consistent metafield strategy makes integrations and theme updates far easier.

Metaobjects: Perfect for custom content types. But don't abuse them - they're not a database replacement.

External Data: When Shopify's limits constrain you, know when to reach for external APIs and services.


Future-Proofing

The decisions that age well:

  • Modular theme sections that can be rearranged
  • Clear separation between content and presentation
  • Documentation for custom code and integrations
  • Graceful fallbacks when third-party services fail
