What is the procedure for including a js file in typescript?

I am trying to import a js file in typescript and access objects and functions within the file. I have added the js file in index.html, but it is not working as expected. I tried using "import '[js file path]'" but it did not work.

import { Component } from '@angular/core';
import { NavController } from 'ionic-angular';
import { NavParams } from 'ionic-angular';
import '../../pages/mobile.js';


@Component({
  selector: 'page-success',
  templateUrl: 'success.html'
})

export class SuccessPage {
  constructor(public navCtrl: NavController, public navParms: NavParams) {

let centerPos =  new atlan.maps.UTMK(953933.75, 1952050.75);

 }
}

This code snippet is from success.ts file where I am trying to locate the 'atlan' object. Any suggestions on how to resolve this issue would be greatly appreciated. Thank you!

Answer №1

In order to avoid compilation errors, it is necessary to utilize the declare keyword. To achieve this, you can follow these steps:

    import { Component } from '@angular/core';
     ....
    /* By using the declare keyword, you are essentially instructing the typescript compiler to 
       disregard this variable as it was not originally created with typescript.*/
    declare var atlan: any; 

    @Component({
      selector: 'page-success',
      templateUrl: 'success.html'
    })

export class SuccessPage {
    ....
}

Answer №2

To ensure the proper functionality of your application, it is important to export the atlan object in your file located at ../../pages/mobile.js. If you have permission to edit this file, make sure to do so and then import the object in the usual manner.
