# composer

> Run Composer commands against the active WordPress checkout.

Run Composer in a one-shot container with the active project checkout mounted at `/workspace`:

```bash theme={null}
sitectl wp composer
sitectl wp composer require vendor/package
sitectl wp composer update vendor/package
```

With no arguments, this runs `composer install --no-interaction`. The helper uses
the host user's UID and GID, bind-mounts the project root, and runs Composer from
that mounted checkout. Commands such as `require`, `remove`, and `update` therefore
persist changes to the checked-in `composer.json` and `composer.lock` instead of
modifying the disposable application image.

Composer also populates the Bedrock installer destinations at `web/app/mu-plugins`,
`web/app/plugins`, and `web/app/themes`. WordPress `dev-mode` bind-mounts all three
directories so the running application sees a local install immediately. With dev
mode disabled, rebuild and deploy after changing Composer dependencies so the
application image is recreated from the updated lockfile.
