Eliminare un file
Per eliminare un file, devi prima
creare un riferimento
a quel file. Quindi chiama il metodo delete() su questo riferimento, che restituisce
un Promise che si risolve o un errore se il Promise rifiuta.

Esistono diversi motivi per cui potrebbero verificarsi errori durante l'eliminazione dei file,
tra cui l'inesistenza del file o la mancanza di autorizzazione
per eliminare il file specificato. Per ulteriori informazioni sugli errori, consulta la sezione

You can change your Firebase Security Rules for Cloud Storage to [allow unauthenticated access for specific situations](/docs/storage/security/rules-conditions#public). However, for most situations, we strongly recommend [restricting access and setting up robust security rules](/docs/storage/security/get-started) (especially for production apps). Note that if you use Google App Engine and have a default Cloud Storage bucket with a name format of `*.appspot.com`, you may need to consider [how your security rules impact access to App Engine files](/docs/storage/gcp-integration#security-rules-and-app-engine-files).\n\nDelete a File\n\nTo delete a file, first\n[create a reference](/docs/storage/web/create-reference)\nto that file. Then call the `delete()` method on that reference, which returns\na `Promise` that resolves, or an error if the `Promise` rejects. \n\nWeb \n\n```javascript\nimport { getStorage, ref, deleteObject } from \"firebase/storage\";\n\nconst storage = getStorage();\n\n// Create a reference to the file to delete\nconst desertRef = ref(storage, 'images/desert.jpg');\n\n// Delete the file\ndeleteObject(desertRef).then(() =\u003e {\n // File deleted successfully\n}).catch((error) =\u003e {\n // Uh-oh, an error occurred!\n});https://github.com/firebase/snippets-web/blob/467eaa165dcbd9b3ab15711e76fa52237ba37f8b/snippets/storage-next/delete-files/storage_delete_file.js#L8-L20\n```\n\nWeb \n\n```javascript\n// Create a reference to the file to delete\nvar desertRef = storageRef.child('images/desert.jpg');\n\n// Delete the file\ndesertRef.delete().then(() =\u003e {\n // File deleted successfully\n}).catch((error) =\u003e {\n // Uh-oh, an error occurred!\n});https://github.com/firebase/snippets-web/blob/467eaa165dcbd9b3ab15711e76fa52237ba37f8b/storage/delete-files.js#L8-L16\n```\n| **Note:** Deleted files are typically recoverable for 7 days with [soft delete](https://cloud.google.com/storage/docs/soft-delete), which is enabled by default.\n\nHandle Errors\n\nThere are a number of reasons why errors may occur on file deletes,\nincluding the file not existing, or the user not having permission\nto delete the specified file. More information on errors can be found in the\n[Handle Errors](/docs/storage/web/handle-errors)\nsection of the docs."]]
