I have an interface which has a callback and it takes two parameters which are moment object. Here is how it looks like

interface IProps {
  callback: (startDate: any, endDate: any) => void
}

This is working for me but I want to be more specific and say that they are not any but moment like so which results in an error:

interface IProps {
  callback: (startDate: moment, endDate: moment) => void
}

How can I fix this?

• javascript
• typescript
• momentjs

• what's the moment interface supposed to be? where is it defined? – toskv Commented Jul 14, 2017 at 8:14

According to moment.d.ts

import * as moment from 'moment';

interface IProps {
  callback: (startDate: moment.Moment, endDate: moment.Moment) => void
}

Import the moment interface/class to your file with: import { moment } from "moment";
