Issue encountered with ng-include compatibility in Angular 5

Just getting started with Angular and working on a small test project using Angular 5 and Visual Code. I'm attempting to use ng-include but the template is not displaying.

  src
     add-device
        add-device.component.html
        add-device.component.scss
        add-device.component.spec.ts
        add-device.component.ts
     edit-device
        edit-device.component.html
        edit-device.component.scss
        edit-device.component.spec.ts
        edit-device.component.ts
     templates
        device.html
     app.module.ts
     app.coponent.ts
     app.component.html
     ....

Here is the simple device.html code:

<div>Include is working!</div>

Now, in the add-device.component.html file:

<div ng-include="" src="'templates/device.html'">
    <div>Insert more unique elements here!</div>
</div>

I have also tried the following variations:

<div ng-include="" src="'templates/device.html'"></div>

<div ng-include="'templates/device.html'"></div>

Unfortunately, the last attempt resulted in an error as ng-include was not recognized:

<ng-include src="'templates/device.html'"></ng-include>

The goal is to utilize the device.html template code in both the add and edit device components. I am utilizing TypeScript for managing the project. When inspecting the Sources in the debugger, the device.html file does not appear in the source list.

Answer №1

Angular has evolved and no longer uses the ng-include directive like AngularJS did.

In Angular, you can create a component in the following way:

@Component({
    selector: 'app-device',
    templateUrl: './device.html'
})
class DeviceComponent {}

Instead of using:

<div ng-include="'templates/device.html'">

You now use:

<app-device></app-device>

How to update Angular version 7 and above

  1. Start by creating a class that implements the OnInit interface

  2. Next, include the module in the app.module.ts file

    @Component({
selector: 'app-device',
templateUrl: '../views/device.component.html',

})

export class DeviceComponent implements OnInit{


ngOnInit(): void {
}



}

    Then, add the component in your view

    <app-device></app-device>
