Utilize static members of an imported type within an Aurelia view

Currently, I am utilizing Aurelia in combination with TypeScript.

In my code, I have defined a simple type with static variables as shown below:

export class MyModule {
    static foo = false;
}

Furthermore, I have created an Aurelia view model as follows:

import {MyModule} from 'my-module';

export class MyViewModel{
    constructor() {
       MyModule.foo = true;
       console.log(MyModule.foo); // Result will be true
    }
}

My intention is to access this static member within my view, demonstrated by the following example:

<p if.bind="MyModule.foo">
   This content will be visible because foo has been set to true.
</p>

However, when referencing the static members of the imported type in the view model, it appears that I am facing some difficulties.

It seems like I may have misunderstood one (or more) concepts within the Aurelia framework. :)

Answer №1

One reason for this issue is that MyModule has not been defined as a member of the class.

You can rectify this by following these steps:

import {MyModule} from 'my-module';

export class MyViewModel{
    constructor() {
       this.myModule = MyModule;
       this.myModule.bar = true;
    }
}

Next, make sure to include:

<p if.bind="myModule.bar">
   This content will be shown when bar evaluates to true.
</p>
