如何缩短打字稿中的界面名称？

Question

suppose i imported a namespace in typescript , lets call it ui , and it has one more namespace called dates and then there is one interface called IDateFormat , but only ui is exported

so if I have to consume the interface i have to do

import {ui} from '..pathToFile'

//to use interface i have to do
const format : ui.dates.IDateFormat

so basically i have to write ui.dates.IDateFormat every time

can i shorten it by assigning to a variable.

like

const intrface : < what's the type> = ui.dates.IDateFormat; // will this work

and use it

but i was thinking what will be the type of such variable and is there any other way to do it?

Answer 1

You can just export it from your own module like this:

export type shortType = ui.dates.IDateFormat;

export interface shortInterface extends ui.dates.IDateFormat {

}

Answer 2

What you are looking for is a type alias . It doesn't use a const declaration:

type Intrface = ui.dates.IDateFormat;

const format : Intrface = …;
