# Command reference

All commands run from your app's directory. Commands that read the app config accept `--config <env>` (`-c`) to use `youcan.app.<env>.json` instead of `youcan.app.json`, see [linked configs](/apps/dev-to-production#_4-separate-environments-with-linked-configs).

## Development

| Command | Description |
| --- | --- |
| `youcan app dev` | Run the app in dev mode: tunnel, dev store subscriptions, and live extension sync. `--no-tunnel` uses localhost directly. |
| `youcan app install` | Open the installation page for your dev store. |
| `youcan app generate extension` | Scaffold a new extension. |

## Deployment

| Command | Description |
| --- | --- |
| `youcan app deploy` | Validate, create a version, and release it to every installed store. `--message` (`-m`) describes the version, `--version` names it, `--no-release` creates it without releasing, `--force` (`-f`) skips the safety prompts. |
| `youcan app versions` | List the app's versions and mark the active one. |
| `youcan app release --version <v>` | Release a specific version by number or name, including an older one, to roll back. |

## Configuration

| Command | Description |
| --- | --- |
| `youcan app config link <env>` | Create `youcan.app.<env>.json` linked to one of your apps. |
| `youcan app config pull` | Update the config file from the active released version. |
| `youcan app env show` | Print the app's environment variables, including its API credentials. |
| `youcan app env pull` | Write those variables to an env file. `--env-file <path>` picks the file, `.env` by default. |
