Metafield Management: Structure for Scale
Instead of creating 50 individual metafields, I used namespaced JSON metafields to store entire configuration objects for our app.
- Namespace Strategy: I used
app_name:settingsto avoid collisions with other apps or merchant custom fields. - JSON Schema Validation: I validate the JSON structure in my app before pushing to Shopify to ensure the storefront liquid code never breaks.
- Definition Sync: I use the Metafield Definition API to ensure our fields appear natively in the Shopify Admin for merchants.
