### Armazenar em cache o esquema OpenAPI { #cache-the-openapi-schema }

Você pode usar a propriedade `.openapi_schema` como um "cache" para armazenar o esquema gerado.

Dessa forma, sua aplicação não precisará gerar o esquema toda vez que um usuário abrir a documentação da sua API.

Ele será gerado apenas uma vez, e o mesmo esquema armazenado em cache será utilizado nas próximas requisições.

                    // Ignore
                    continue
                }

            if (shouldDelete(cacheVersion)) {
                logger.lifecycle("Removing old cache directory : $cacheDir")
                delete {
                    delete(cacheDir)
                }
            }
        }
    }
