Installation

npm i @karhoo/demand-api

Usage

You can use each service separately, or you can use getApi method which returns all available services

import {
  getApi,
  HttpService,
  LocationService,
  PoiService,
  QuotesV2Service,
  errorCodes,
} from '@karhoo/demand-api'

const url = 'https://public-api.karhoo.com' // please note that there should not be a slash at the end of the url

const correlationIdPrefix = 'prefix'

const requestOptionsGetter = () => ({
  headers: {
    'custom-header': 'Custom header',
  },
})

const middleware = <T>(response: HttpResponse<T>): HttpResponse<T> => {
  console.log(response.status)

  return response
}

Please note that by default fetch will be called with following config

{
  credentials: 'include',
  mode: 'cors',
}

You can override this default settings using defaultRequestOptionsGetter

getApi usage:

All config fields are optional, default value for url - https://public-api.karhoo.com in case if NODE_ENV === 'production', otherwise https://public-api.sandbox.karhoo.com.

Default value for correlationIdPrefix - ''.

Default value for authServiceDefaultOptionsGetter - () => ({}).

const options = {
  url,
  defaultRequestOptionsGetter: requestOptionsGetter,
  authServiceDefaultOptionsGetter,
  responseMiddleware: middleware,
  correlationIdPrefix,
}

const api = getApi(options)

Http service usage:

const apiV1 = 'https://public-api.karhoo.com/v1' // please note that version should be specified

const httpService = new HttpService(url)
  .setCorrelationIdPrefix(correlationIdPrefix)
  .setDefaultRequestOptionsGetter(requestOptionsGetter)
  .setResponseMiddleware(middleware)

const response = await httpService.post('locations/address-autocomplete', { query: 'lond' })

Location service usage:

const locationService = new LocationService(httpService)

Poi service:

const poiService = new PoiService(httpService)

Quotes service:

:warning: QuotesService is deprecated. Please use QuotesV2Service instead

const quotesService = new QuotesV2Service(httpService)

Trip service:

const tripService = new TripService(httpService)

Fare service:

const fareService = new FareService(httpService)

Payment service:

const paymentService = new PaymentService(httpService)

Flags service:

const flagsService = new FlagsService(httpService)

User service:

const userService = new UserService(httpService)

Auth service:

const authService = new AuthService(httpService)

Example

Let's see how to use one of the services, listed above.

For example, you need to get a list of quotes for trip from one location to another. For this purpose you have to use Quotes service and call quotesSearch method:

const quotesSearchParams = {
  origin: {
    latitude: '51.501364',
    longitude: '-0.14189',
    displayAddress: 'Buckingham Palace, London SW1A 1AA',
  },
  destination: {
    latitude: '41.78650',
    longitude: '1.78954',
    displayAddress: 'Big Ben, Westminster, London SW1A 0AA, UK',
  },
  local_time_of_pickup: '2020-05-12T10:00',
}

const quotesResponse = quotesService
  .quotesSearch(quotesSearchParams)
  .then(result => {
    //handleResult
  })
  .catch(error => {
    //handle error
  })
