Converting moment date to graphql iso date in moment date range?-CodePudding

I am building a graphql api. I am using moment and moment range to pick date range from database. But I am facing one problem.

This is graphql Schemas-

gql`
  extend type Query {
        getAllBookedDate(roomId: ID!): Date
  }
`

This is the resolvers

const Moment = require('moment');
const {extendMoment} = require("moment-range");
const moment = extendMoment(Moment);
getAllBookedDate: combineResolvers(isAuthenticated, async (_, {roomId}) => {
            const bookings = await Booking.find({room: roomId});
            let bookedDates = [];
            bookings.forEach(booking => {
                const range = moment.range(moment(booking.checkInDate), moment(booking.checkOutDate));
                const dates = Array.from(range.by('day'));
                bookedDates = bookedDates.concat(Moment([...dates]).toISOString());
            });
            console.log(bookedDates); /// Result is like folowing codes
            return {
                bookedDates
            }
})

Here I get console.logged result like image-

[
  Moment<2016-07-20T18:00:15 06:00>,
  Moment<2016-07-21T18:00:15 06:00>,
  Moment<2016-07-22T18:00:15 06:00>,
  Moment<2016-07-23T18:00:15 06:00>,
  Moment<2016-07-24T18:00:15 06:00>,
  Moment<2016-07-25T18:00:15 06:00>,
  Moment<2016-07-26T18:00:15 06:00>,
  Moment<2016-07-27T18:00:15 06:00>,
  Moment<2016-07-28T18:00:15 06:00>,
  Moment<2016-07-29T18:00:15 06:00>,
  Moment<2016-07-30T18:00:15 06:00>
]

Here I am returning this array. I use graphql-iso-date for Scalar in Graphql. I don't know how can I convert above date into iso date. That's why I am facing this problem.

CodePudding user response：

I can see, your date array is not a format date to iso. You have to format date before send it to graphql. So change the code--

gql`
  extend type Query {
        getAllBookedDate(roomId: ID!): [Date]
  }
`

And Resolver:

const Moment = require('moment');
const {extendMoment} = require("moment-range");
const moment = extendMoment(Moment);
getAllBookedDate: combineResolvers(isAuthenticated, async (_, {roomId}) => {
            const bookings = await Booking.find({room: roomId});
            let bookedDates = [];
            bookings.forEach(booking => {
                const range = moment.range(moment(booking.checkInDate), moment(booking.checkOutDate));
                const dates = Array.from(range.by('day'));
                bookedDates = bookedDates.concat(Moment([...dates]).toISOString());
            });
            bookedDates = bookedDates.map(a => a.toISOString());
            return bookedDates;
})

That's it. Try it. I think it work properly now. If not working please let me know. Thank you very much.
