Toma como parâmetro um objeto stringificado e outro objeto, converte, mapeia e retorna o objeto stringificado com as propriedades atualizadas. As propriedades desconexas são descartadas.
Sem mapeador:
const example: Example = {
data: "{\"name\": \"example\",\"description\": \"this is an example\",\"extra\": \"\",\"size\": \"123\", \"price\": 100}",
}
const inputData: IExampleDTO = {
name: undefined,
description: "this is a new description",
extra: "this is an extra",
size: undefined,
price: 20,
};
const updatedData = JSON.parse(example.data)
updatedData.name = inputData.name,
updatedData.description = inputData.description,
updatedData.extra = inputData.extra,
updatedData.size = inputData.size,
updatedData.price = inputData.price,
await this.examplesRepository.update(
{
...example,
data: JSON.stringify(updatedData),
},
trx,
);
output => example.data = "{\"name\": \"\",\"description\": \"this is a new description\",\"extra\": \"this is an extra\",\"size\": \"\", \"price\": 20}";
Usando mapeador:
import { updateString } from "@utils/mappers";
const example: Example = {
data: "{\"name\": \"example\",\"description\": \"this is an example\",\"extra\": \"\",\"size\": \"123\", \"price\": 100}",
}
const inputData: IExampleDTO = {
name: undefined,
description: "this is a new description",
extra: "this is an extra",
size: undefined,
price: 20,
};
await this.examplesRepository.update(
{
...example,
data: updateString(example.data, inputData),
},
trx,
);
output => example.data = "{\"name\": \"\",\"description\": \"this is a new description\",\"extra\": \"this is an extra\",\"size\": \"\", \"price\": 20}"
