"Ensure that a directive is universally accessible throughout an angular2 final project by registering it

I have created a custom directive that I want to use throughout my application. How can I register my directives so they are accessible in the entire application? I have found outdated solutions for this issue and need a solution specific to Angular 2 final version 2.1.0.

Here is an excerpt from my main.ts file:

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';

//enableProdMode(); //Uncomment for production
platformBrowserDynamic().bootstrapModule(AppModule)
    .then((success: any) => console.log('App bootstrapped'))
    .catch((err: any) => console.error(err));

My application consists of 6 modules for lazy loading purposes:

appmodule 
--contact module
--project module
--restmodules
...

Initially, when I registered the directive in the product module, it worked well. To use this directive in other modules, I registered it in my appmodule.ts as shown below:

import { mdinput} from './shared/mdinput.directive';


@NgModule({
    imports: [
               AppRoutingModule

    ],
    declarations: [
        AppComponent,mdinput

    ],
    providers: [DataService],
    bootstrap: [AppComponent]
})
export class AppModule {
}

Currently, this particular directive is not functioning properly without any error messages being displayed.

Answer №1

To start, create a new Directive in its own folder. For example, let's say you make a directive called myHighlight.directive.ts in the customDirectives directory. Next

import { HighlightDirective } from 'yourpath/customDirectives/myHighlight.directive';

and

declarations: [..., HighlightDirective]

include these in app.module.ts.

Now you can utilize this in any component's view:

<td  myHighlight>{{user.name | capitalize}}</td>

Here's how it will function.

Answer №2

To incorporate the functionality, simply include it in a feature module and then add that feature module to the imports: [...] section of the desired module.

Even directives like *ngIf and *ngFor now require this method by importing either CommonModule or BrowserModule into the imports array.
