Work on an existing app

• You've created a Partner account and a development store.

• You understand how apps fit into Shopify.

• You've installed Node.js 16 or higher.

• You've installed a Node.js package manager: either npm, Yarn 1.x, or pnpm.

• You've installed Git 2.28.0 or higher.

• You're using the latest version of Chrome or Firefox.

1. If you haven't already, clone the app that you want to work on, and then navigate to the project directory.

2. Run your package manager's install command to install the project's dependencies. Shopify CLI is a dependency of all apps created with Shopify 3.0 or higher.

After you install the dependencies for the app, check the version to make sure that Shopify CLI is available.

After you install your app's dependencies locally, you can work with it by building the app and starting a local development server.

Shopify CLI uses Cloudflare to create a tunnel that allows your app to be accessed using a unique HTTPS URL. Press p to open your app's preview URL in a browser.

1. Navigate to your newly-created app directory.

The CLI walks you through the following:

• Logging into your Shopify Partner account and, if needed, selecting a Partner organization
• Linking your app to an existing app in the Partner Dashboard, or creating a new app.
• Creating a new configuration file for your local development environment.
• Creating a tunnel between your local environment and the development store using Cloudflare
• Installing your app on a development store

To learn more about the processes that are executed when you run dev, refer to the Shopify CLI command reference.

To learn more about managing your app's configuration locally, refer to App configuration.
