Guide to utilizing the translate pipe in TypeScript rather than the template in Angular 6

Currently, I have a specific need that involves utilizing the translate pipe from Angular within TypeScript logic.

I referred to a similar query: How to use pipe in ts not HTML

Additionally, I explored this informative link as well: Translate your Angular App with Pipes

The solution provided in the above question works, but it was based on a custom pipe. In my scenario, the translate pipe is already built-in and is responsible for language translation of text. Here is an example snippet from my template:

<my-component
  [myLabel1]="label1 | translate"
  [myLabel2]="label2 | translate"
  [myLabel3]="label3 | translate"
  [myLabel4]="label4 | translate"
  [myLabel5]="label5 | translate"
  [myLabel6]="label6 | translate">
</my-component>

To simplify the usage of multiple directives, I devised a solution involving an interface to group all directives into a single object:

<my-component
  [toChildAsInput]="labelObject">
</my-component>

I have defined an interface called: labelconfig.ts

export interface LabelConfig {
    label1: string;
    label2: string;
    label3: string;
    label4: string;
    label5: string;
    label6: string;
}

Here's how I'm handling it in TypeScript:

import { LabelConfig } from './labelconfig';
labelObject:LabelConfig ;
ngOnInit() {
  labelObject.label1="Hello";  // How can I implement the pipe here?
  ...
}

My progress seems to be halted at this point. I am seeking guidance on how I can apply the same pipe within TypeScript. Any assistance would be greatly appreciated. Is this task feasible or not?

Answer №1

If you have defined your pipe at the module level, you can easily inject it or provide it at the component level in providers

providers: [ TranslatePipe ]

constructor(private translate: TranslatePipe) {}

Then simply use transfom on the injected instance in the component

this.data = this.translate.transform(value)
