Starts a local development environment that serves your project. When the environment is ready, the command prints links to preview your app on your development site: in the site, the editor, and the dashboard.
The development environment is set up for hot reloading, so any changes you make to your code are immediately reflected in the browser.
Note: wix app dev runs your app on a development site. To install your app on one, switch to another, or set one in a non-interactive environment, see Work with Development Sites.
The following flags are available for the wix app dev command:
| Flag | Description |
|---|---|
--port <port> | Specify which port to run on. |
--allowed-hosts <allowedHosts> | Specify a comma-separated list of allowed hosts. |
