Essential Tools for Shopify App Development

Complete development of a Shopify app requires the right set of tools. Here are some must-have resources for a Shopify developer:

1. Shopify CLI (Command Line Interface)
   The Shopify CLI pretty much simplifies shopify development, automating common tasks like authentication, project setup, app setup, and quick testing.

2. Shopify Partners Dashboard
   Before you start coding, register as a Shopify Partner to gain access to dashboard, development tools, API keys, and local development environments.

   The Shopify API is the backbone of creating a Shopify app. Allowing apps to interact totally with store data. The key APIs include:

• Admin API – Manages Shopify admin, store data, products, and orders.

• Storefront API – Enables custom storefront experiences.

• GraphQL API – Allows efficient API calls with minimal requests.

4. Ngrok
   Since Shopify requires a secure HTTPS connection, Ngrok provides an easy way to expose your backend local development server to the web.

5. React & Polaris UI Framework
   For building user-friendly interfaces, Shopify provides Shopify’s Polaris design system, a UI framework designed for Shopify apps. Using React ensures smooth performance for app using JavaScript.
