previously replicated need to be re-synced, the `mc replicate resync start` command with optional flag of `--older-than` needs to be used to trigger re-syncing of previously replicated objects. This command generates a ResetID which is a unique UUID saved to the remote target config along with the applicable date(defaults to time of initiating the reset). All objects created prior to this date are eligible for re-replication if existing object replication is enabled for the replication rule the object...

#### Instalar `openapi-ts`

Puedes instalar `openapi-ts` en tu código de frontend con:

<div class="termy">

```console
$ npm install @hey-api/openapi-ts --save-dev

---> 100%
```

</div>

#### Generar el Código del Cliente

Para generar el código del cliente puedes usar la aplicación de línea de comandos `openapi-ts` que ahora estaría instalada.

		tx.RowsAffected = rowsAffected
	default:
		tx = db.getInstance()
		tx.Statement.Dest = value
		tx = tx.callbacks.Create().Execute(tx)
	}
	return
}

// Save updates value in database. If value doesn't contain a matching primary key, value is inserted.
func (db *DB) Save(value interface{}) (tx *DB) {
	tx = db.getInstance()
	tx.Statement.Dest = value

	reflectValue := reflect.Indirect(reflect.ValueOf(value))

// Endpoint set represents parsed ellipses values, also provides
// methods to get the sets of endpoints.
type endpointSet struct {
	argPatterns []ellipses.ArgPattern
	endpoints   []string   // Endpoints saved from previous GetEndpoints().
	setIndexes  [][]uint64 // All the sets.
}

// Supported set sizes this is used to find the optimal
// single set size.

    results = some_library()
    return results

Si votre application n'a pas à communiquer avec une bibliothèque externe et pas à attendre de réponse, utilisez `async def`.

---

Si vous ne savez pas, utilisez seulement `def` comme vous le feriez habituellement.

**Note** : vous pouvez mélanger `def` et `async def` dans vos *fonctions de chemin* autant que nécessaire, **FastAPI** saura faire ce qu'il faut avec.

    if (elements instanceof ImmutableCollection) {
      /*
       * TODO: When given an ImmutableList that's a sublist, copy the referenced
       * portion of the array into a new array to save space?
       */

      return list.asList();

Now that we have all the security flow, let's make the application actually secure, using <abbr title="JSON Web Tokens">JWT</abbr> tokens and secure password hashing.

This code is something you can actually use in your application, save the password hashes in your database, etc.

We are going to start from where we left in the previous chapter and increment it.

## About JWT { #about-jwt }

JWT means "JSON Web Tokens".
