Shopify Development Setup

Before writing code

Fetch live docs:

1. Fetch https://shopify.dev/docs/api/shopify-cli for CLI installation and commands
2. Web-search site:shopify.dev getting started app development for app setup
3. Web-search site:shopify.dev theme development getting started for theme setup

Prerequisites

Shopify Partner Account

All Shopify development starts with a Partner account:

• Free at https://partners.shopify.com/
• Provides access to development stores (unlimited), app management, and theme development
• Development stores have full Shopify features without charges

Development Stores

Two types:

• Development store — full-featured test store, cannot process real payments
• Shopify Plus sandbox — for testing Plus-specific features

Shopify CLI

The primary development tool:

• Install: npm install -g @shopify/cli or brew install shopify-cli
• Authenticate: shopify auth login
• Key commands: shopify app init, shopify theme init, shopify hydrogen init

Deprecated Technologies Warning

Do NOT use these deprecated tools:

• Slate — deprecated theme build tool, replaced by Shopify CLI
• Theme Kit — legacy theme deployment, replaced by shopify theme CLI commands
• Timber — deprecated starter theme, replaced by Dawn

Best Practices

• Use shopify app init or shopify theme init to scaffold projects — do not set up manually
• Always start with a development store — never develop against a production store
• Use the latest stable API version (check https://shopify.dev/docs/api/usage/versioning)
• Keep .env in .gitignore
• Use shopify app dev for local development with hot reload and tunnel
• Run shopify theme check before deploying themes

Fetch the Shopify CLI docs and getting-started guides for exact commands and latest project structures before setting up.
