Shopify Dev Diagnostics Suite
The Opportunity
A toolkit for partners to catch API/CLI mismatches, test Functions (e.g., discount strategies), and simulate Admin/Liquid data (like Order Printer arrays). Saves hours of trial-and-error.
"Developers face version mismatches and opaque errors (e.g., discountApplicationStrategy=ALL not recognized, Liquid arrays unreadable, fulfillment errors)."
Market Validation
Detailed Analysis
Proposed Solution
CLI plugin + web dashboard that validates project configs against shop capabilities, spins up test harnesses for Discounts/Functions, and lint-checks API payloads with human-readable error tips.
Target Audience
Shopify app/agency developers and tech-savvy merchants
Competitive Landscape
Shopify CLI (baseline), none with comprehensive diagnostics and guided fixes
Implementation Notes
Build a version matrix service mapping CLI/app/Functions support; parser for TOML manifests with upgrade recs; stubs to execute Discount Functions against sample carts; Liquid previewer for Order Printer contexts; API payload linter for Fulfillment endpoints; integration tests against development stores; VS Code extension for inline warnings.
