})
let expensiveOperationPromise = null
let expensiveOperationResult = null
const cacheExpensiveOperation = async () => {

How to add a factory taking parameter into Nette DIC. Both ways, using config.neon and compiler extension, have the same result.

$container->addDefinition($this->prefix('formMapperFactory'))
->setImplement('Namespace\IFactory')

Trable s kódem
Nette mi pravděpodobně kvůli Nelle vyhazuje fatal error v kešovaném konfigu, k odstranění stačí:
1) přidat na začátek kešovaného souboru die('G');
2) soubor spustit, ať zemře na lajně přidané v kroku 1)
3) zakomentovat řádek se smrtí
Po této proceduře se fatal error přestane objevovat! Žádný racionální důvod proč to tak je mě fakt nenapadá :/.
