The Wix CLI is the command-line tool for creating, developing, and deploying Wix apps. It generates a complete project structure, handles initial setup and configuration, and provides commands to generate extensions and manage your app throughout development.
New CLI projects include Wix skills, so AI tools can perform CLI tasks for you. This lets you focus on building the unique features of your app.
To get started, see Quick Start a Wix CLI App.
For a walkthrough of building an app with the CLI, watch the video tutorial:
The CLI generates the complete project structure needed for Wix app development. You can:
The CLI uses a standardized project structure based on the Astro web framework. Astro offers a performance-focused architecture, partial hydration, and a flexible component model that lets you mix vanilla HTML/CSS/JS with React, Vue, or Svelte components as needed.
The CLI also supports backend development with HTTP endpoints.
For a per-folder breakdown of the generated project, see Wix CLI Project Structure.
When developing apps, you test your functionality on development sites, which are premium Wix sites used for app testing. You can maintain up to 5 development sites simultaneously to test different aspects of your app.
Wix apps aren't standalone web apps. They need to be installed on a Wix site to run.
When you create your CLI app, you're prompted to choose or create a development site. As you work locally with the CLI, you can open different parts of your app on the development site in your browser by running the dev command. The development environment supports hot reloading, so any changes you make to your code are immediately reflected in the browser.
After developing and testing your CLI app locally, you can build it, create shareable previews, and release new app versions for distribution. For more information, see Build and Deploy a Project with the Wix CLI.
The CLI provides a serverless hosting solution where scaling, resource allocation, and maintenance are fully managed by Wix:
Check which version of the CLI you have:
Upgrade to the latest:
Note: If the latest version of the CLI includes a new command, you'll need to add the new command to your package.json file.
The Wix CLI replaces the Legacy Wix CLI for Apps, which no longer receives updates or feature additions. Use the legacy reference only if you're maintaining an existing app built with the Legacy CLI.
