Format Data

Formatting data transforms the raw response so the exposed data is easier to use directly.

dataKey (Built-in Extraction)

createRequest's dataKey config auto-extracts data — no manual handling needed.

const useApi = createRequest({ dataKey: 'data' })

formatData (Post-Processing)

formatData further processes data after dataKey extraction.

const { data } = useApi(service, {
  formatData: (data, rawData, params) => {
    return data.map(item => ({
      ...item,
      fullName: `${item.firstName} ${item.lastName}`,
    }))
  },
})
