How to get the response time from Axios

api.js

const axios = require('axios').default
const API_BASE_URL = 'https://api.spacexdata.com/v3'
      
const API = axios.create({
  baseURL: API_BASE_URL
})

/*
 * setting interceptors to be able
 * to know response time of the each request
 */
API.interceptors.request.use(
  config => {
    const newConfig = { ...config }
    newConfig.metadata = { startTime: new Date() }
    return newConfig
  },
  error => {
    return Promise.reject(error)
  }
)
API.interceptors.response.use(
  response => {
    const newRes = { ...response }
    newRes.config.metadata.endTime = new Date()
    newRes.duration =
      newRes.config.metadata.endTime - newRes.config.metadata.startTime
    return newRes
  },
  error => {
    const newError = { ...error }
    newError.config.metadata.endTime = new Date()
    newError.duration =
      newError.config.metadata.endTime - newError.config.metadata.startTime
    return Promise.reject(newError)
  }
)
