Bulk Product Editor App (Shopify Admin App)

Overview

This project is a custom Shopify Admin app that allows merchants to safely perform bulk updates on products using Shopify’s GraphQL Admin API and Bulk Operations.

---

The app focuses on demonstrating:

• Correct usage of Shopify bulk operations
• Clear UX for admin workflows
• Thoughtful technical decision-making
• Proper handling of platform constraints (rate limits, async execution)

The implementation intentionally prioritizes quality, reliability, and clarity over exhaustive feature coverage.

---

Objectives

• Enable merchants to select multiple products
• Apply bulk changes efficiently using Shopify Bulk Operations
• Provide a preview of changes before execution
• Track operation progress and results
• Allow undo for supported operations
• Demonstrate best practices for Shopify app development

---

Implemented / Planned Features

Product Selection

• Manual selection via table (IndexTable)
• Basic filters:
  • Product status
  • Product tags

Bulk Operations

• Bulk price adjustment:
  • Percentage-based increase/decrease
  • Executed via bulkOperationRunMutation
• One active bulk operation per store (Shopify constraint)

Preview Mode

• Simulated preview (no dry-run mutation)
• Before / after comparison for affected fields
• Highlighted differences for clarity

Progress & Feedback

• Operation status tracking (CREATED, RUNNING, COMPLETED, FAILED)
• Visual progress indicator
• Clear success and error feedback

Operation History

• List of executed bulk operations
• Metadata stored for auditing and undo

Undo Support (Limited Scope)

• Undo implemented as inverse operations
• Currently supported for price adjustments only

---

Out of Scope (By Design)

The following features are intentionally excluded to keep the solution focused and aligned with Shopify platform realities:

• Full product versioning or snapshots
• Complex find-and-replace for rich HTML descriptions
• Parallel execution of multiple bulk operations
• Canceling an in-progress bulk operation
• Advanced search or collection-based segmentation

These limitations are documented and discussed in the technical design.

Architecture Overview

Components

1. Frontend (React + Polaris)

   • Embedded Shopify Admin UI
   • Product selection with filters
   • Preview and confirmation flows
   • Progress tracking and history

2. Backend (Node.js + TypeScript)

   • Shopify session management
   • GraphQL API communication
   • Bulk operation orchestration
   • SQLite persistence

3. Database (SQLite)

   • Operation metadata and history
   • Undo payloads
   • Status tracking

Data Flow

User Selection → Preview → Confirmation → Bulk Operation → Polling → Results → History

---

Shopify API Usage

Required Scopes

• write_products - Required for bulk product updates

Key GraphQL Operations

• bulkOperationRunMutation - Execute bulk operations
• productVariantsBulkUpdate - Update variant prices
• Product queries with filters and pagination

Bulk Operations Strategy

• One operation per store - Shopify platform constraint
• Asynchronous execution - Polling for status updates
• JSONL file upload - Efficient data transfer
• Result processing - Parse success/failure from JSONL

---

Setup Instructions

Prerequisites

• Node.js 20.19+ or 22.12+
• Shopify CLI
• Development store (for testing)

Installation

# 1. Clone repository
git clone 
cd bulk-product-editor

# 2. Install dependencies
npm install

# 3. Setup database
npm run setup

# 4. Start development server
npm run dev

First-Time Setup

1. Create Shopify Partner Account: https://partners.shopify.com
2. Create Development Store: Partners Dashboard → Stores → Add store
3. Install App: Follow Shopify CLI prompts during npm run dev
4. Grant Permissions: Accept write_products scope

---

Known Limitations

Platform Constraints

• One bulk operation at a time per store (Shopify limitation)
• Asynchronous execution - operations cannot be cancelled once started
• 7-day result retention - JSONL results expire after 7 days

Implementation Scope

• Price adjustments only - Other bulk operations not implemented
• Basic product filters - Status and tags only
• Undo for price adjustments - Other operation types not supported

Error Handling

• Rate limits - Respects Shopify API limits
• Partial failures - Individual product failures are tracked
• Network resilience - Retry logic with exponential backoff

---

Development Notes

Code Organization

• /app/routes - React Router pages and API endpoints
• /app/services - Business logic and Shopify API integration
• /app/models - Database operations (Prisma)
• /docs - Technical documentation

Key Files

• app/routes/app._index.tsx - Main product selection and bulk operation UI
• app/routes/app.history.tsx - History and operation products tracking
• app/services/bulk-operations.server.ts - Shopify bulk operation handling
• app/services/products.server.ts - Product data and preview logic
• app/models/operation.server.ts - Database operations for history

Testing Considerations

• Test with various product catalog sizes
• Verify bulk operation polling under different network conditions
• Validate undo operations create correct inverse payloads
• Ensure proper cleanup of expired operations
