Project Memory

Project Context

This project (product_inventory) integrates Google Sheets with Shopify. It serves as a master inventory management tool where users edit product data in a Google Sheet, and scripts automatically sync those changes to Shopify.

Critical Components:

• Google Apps Script: Runs the logic.
• "vars" Sheet: Holds all configuration and API keys. NEVER hardcode credentials.
• Shopify Admin API: Used for syncing. REST for Orders, GraphQL for Products.

Work Patterns & Agreements

1. Documentation First: Before implementing complex features, we update the plan and often the documentation (README/ARCHITECTURE).
2. Safety First: We use SafeToAutoRun: false for commands that deploy or modify external state until verified.
3. Strict Typing: We use TypeScript. No any unless absolutely necessary (and even then, we try to avoid it).
4. Artifact Usage: We use task.md, implementation_plan.md, and walkthrough.md to track state.

Key Technical Decisions

• Queue System: We implemented onEditQueue.ts to batch edits. This prevents hitting Shopify API rate limits and Google Apps Script execution limits during rapid manual edits.
• Hybrid API: We use REST for retrieving Orders (legacy/easier for flat data) and GraphQL for Products (more efficient/flexible).
• Global Exports: Functions in src/global.ts are explicitly exposed to be callable by Apps Script triggers.

User Preferences

• OS: Windows.
• Shell: PowerShell.
• Node Manager: fnm.
