How can I retrieve a global variable in Angular that was initialized within an IIFE?

I'm a beginner in Angular, so I ask for your patience. Currently, I am in the process of migrating an app from Asp.net MVC5 to Angular. One of the key functionalities of this application involves connecting to a third-party system by downloading a JavaScript file that establishes credentials and facilitates communication through an object. It appears that this object is immediately invoked function expression (IIFE), meaning it gets initialized as soon as the JavaScript file loads. To dynamically load the script in my component, I have successfully added it to the head of the document. However, my challenge lies in accessing that object within my component after the IIFE has executed. Despite verifying that the external file is being loaded and the object is initialized through browser developer tools, I am unable to find a solution because this JavaScript file cannot be obtained from npm or included in my assets folder.

Answer №1

To store data within your component, you can create a variable and update the immediate-invoked function expression (iife) to assign the desired information to it as shown below:

export class MyComponent{

    MyNewVariable: string; //or choose any other type needed

    constructor(){}

    (function(){
        //perform actions
        this.MyNewVariable = data; //data represents the information you want to store
    })();
}

After setting up the variable with the data, you can then proceed to run another function that utilizes this stored information in some way.
