I'm trying to rename all the keys in an object to a new and different key which is value but all solutions I found on the internet show how to add a prefix to an existing key thus renaming it.
I have the following implementation
const shippingOption = {
"": "Automatic",
"ES_CartasNacionalesDeMas20": "Correos: cartas ordinarias, 2-4 Days",
"ES_CorreosCartasCertificadas": "Correos: cartas certificadas, 2-4 Days",
"ES_CorreosCartasCertificadasUrgentes": "Correos: cartas certificadas urgentes, 1-2 Days",
"ES_CorreosChronoexpres": "Correos Express / Paq 24, 1 Day",
"ES_CorreosPaq48": "Correos: Paq Premium, 2 Days",
"ES_CorreosPaq72": "Correos: Paq Estándar, 2-3 Days",
"ES_EconomyDeliveryFromAbroad": "Envío económico desde el extranjero, 10-22 Days",
"ES_EconomyShippingFromGC": "Envìo economico desde China/Hong Kong/Taiwan to worldwide, 11-35 Days",
"ES_EconomySppedPAK": "Envìo SpeedPAK economico desde China/Hong Kong/Taiwan, 10-15 Days",
"ES_ENTREGA_KIALA_8KG": "Entrega a un punto Kiala (hasta 8 kg), 2-4 Days",
"ES_EntregaConInstalacion": "Entrega con instalación (ver detalles), 3-5 Days",
"ES_EntregaEnElPortal": "Entrega en el portal (ver detalles), 3-5 Days",
"ES_EntregaEnNacexShop": "Entrega en NACEX.shop, 1-2 Days",
"ES_EnvioEstandarAIslasBalearesCeutaMelilla": "Envío estándar a Ceuta/Melilla, 3-7 Days",
"ES_EnvioEstandarALasIslasCanarias": "Envío estándar a las islas Canarias, 3-7 Days"
}
let renamed = Object.entries(shippingOption).reduce((acc, [k, v]) => {
return { ...acc,
[`value[${k}]`]: v
};
}, {})
console.log(renamed)Expected results
const shippingOption = {
"value": "Automatic",
"value": "Correos: cartas ordinarias, 2-4 Days",
"value": "Correos: cartas certificadas, 2-4 Days",
"value": "Correos: cartas certificadas urgentes, 1-2 Days"
}
I want every key in the object to be renamed to value How can I do this?
Your reducer should just use v instead of k if you want to name using the value of each property:
let renamed = Object.entries(shippingOption).reduce(
(acc, [k, v]) => {
return { ...acc, [`value[${v}]`]: v};
},
{},
);
Note that if you have 2 identical values, they will overwrite each other so that you will only end up with the last one.
You can use mapped types and string literal to type the result of this operation:
type ValueKey<K extends string> = `value[${K}]`
type ConvertToValueKeys<T> = {} & { [K in keyof T & string as ValueKey<K>]: T[K] }
let renamed= Object.entries(shippingOption).reduce((acc, [k, v]) => {
return { ...acc, [`value[${k}]`]: v};
}, {} as ConvertToValueKeys<typeof shippingOption>)
renamed["value[ES_CartasNacionalesDeMas20]"] // ok
renamed["value[ES_CartasNacionalesDeMas210]"] // err
