How to Create a Shopify App: Step-by-Step

Prerequisites

Before you build a Shopify app, you need:

What You Need

• [Shopify Partner account](https://partners.shopify.com) - Free to create
• [Shopify CLI](https://shopify.dev/docs/apps/tools/cli) - Development tool
• Node.js v18+ (if using Node.js stack)
• Code editor (VS Code recommended)
• Git for version control
• Understanding of JavaScript/TypeScript
• Knowledge of web development basics

Step-by-Step: Create Shopify App

1. 1

   Create Shopify Partner Account

   Go to [partners.shopify.com](https://partners.shopify.com) and sign up for a free Partner account. This gives you access to development tools, unlimited development stores, and the ability to publish apps. Verify your email address to activate the account.

2. 2

   Install Shopify CLI

   Install [Shopify CLI](https://shopify.dev/docs/apps/tools/cli) globally: `npm install -g @shopify/cli @shopify/app`. Verify installation with `shopify version`. The CLI provides commands to create, develop, and deploy apps.

3. 3

   Authenticate with Partner Account

   Run `shopify auth login` in your terminal. This opens your browser to authenticate with your Partner account. The CLI stores your credentials for future use. You'll need to authenticate once.

4. 4

   Create New App Project

   Run `shopify app init` in your terminal. The CLI asks: App name, Preferred package manager (npm/yarn), Template (Node.js, PHP, or Ruby), Frontend framework (React recommended). This creates a scaffolded app with all necessary files.

5. 5

   Set Up Development Store

   Create a development store from your Partner Dashboard. This is a free test store where you'll develop and test your app. You can create unlimited development stores. The app connects to this store for testing.

6. 6

   Start Development Server

   Navigate to your app directory and run `shopify app dev`. This starts the development server, creates a tunnel for local development, and connects your app to your development store. Your app URL opens automatically.

7. 7

   Develop App Functionality

   Build your app features: Use Shopify APIs (Admin API, Storefront API) to interact with store data, Build admin interface for merchants, Create user-facing features if needed, Implement authentication and security, Add database for app data storage.

8. 8

   Test Your App

   Test all functionality in your development store: Install app and test features, Test API integrations, Check error handling, Test on different devices, Verify security and permissions. Fix any bugs before submission.

9. 9

   Prepare for App Store Submission

   Prepare app listing: Write app description, Create screenshots and app icon, Set pricing and plans, Write privacy policy, Create user documentation, Test thoroughly one more time, Ensure compliance with App Store guidelines.

10. 10

    Submit to App Store

    Submit app through Partner Dashboard: Fill out app listing details, Upload app code, Submit for Shopify review (typically takes 2-4 weeks), Address any feedback from reviewers, Once approved, your app is live in the App Store.

Shopify Application Development Process

Development Workflow

Shopify application development follows this workflow:

Phase	Activities	Duration
Planning	Define features, architecture, APIs needed	1-2 weeks
Design	UI/UX design, wireframes, database design	2-3 weeks

Shopify Plugin Development Explained

Apps vs Plugins

Important Note: Shopify uses apps, not traditional “plugins”. However, Shopify plugin development is often used interchangeably with app development. Here’s the distinction:

Understanding the Terminology

• Shopify Apps - Full applications that integrate via APIs
• Plugins - More commonly used for WordPress, Joomla
• Shopify 'plugins' - Usually refers to Shopify apps
• Development process is the same regardless of term used

For Shopify development, you build apps (not plugins). The process involves:

• Creating applications that integrate with Shopify
• Using Shopify APIs for functionality
• Publishing to App Store (for public apps)
• Same development approach whether called “app” or “plugin”

What is Shopify application development?

Shopify application development (same as Shopify app development) involves building applications that integrate with Shopify stores to add functionality. Applications can be: Public apps (published to App Store), Private apps (for specific stores), Custom apps (for enterprise stores), or Embedded apps (integrated into Shopify admin). Development includes: Backend development (server-side logic), Frontend development (admin interface), API integration with Shopify, Database setup for app data, Authentication and security, Billing implementation for paid apps, Testing and quality assurance, and App Store submission. Applications enhance store functionality and help merchants run their businesses more effectively.

What is Shopify plugin development?

Shopify doesn't use traditional 'plugins' - instead, it uses 'apps' that integrate via APIs. However, 'Shopify plugin development' often refers to Shopify app development. Some developers use 'plugin' and 'app' interchangeably, but technically: Shopify Apps are full applications that integrate with stores, while plugins are more commonly associated with WordPress. For Shopify, you develop apps (not plugins) that merchants install from the App Store or use privately. The development process is the same whether you call it app or plugin development - building applications that extend Shopify functionality.
