Intlayer Angular Usage

Core Philosophy

Intlayer promotes Component-Level Content Declaration. Instead of a massive global translation file, content is declared in *.content.ts files adjacent to the Angular components that use them.

Workflow

To create a translated component, you need two files:

1. Declaration: A content file (e.g., my-component.content.ts) defining the dictionary.
2. Implementation: An Angular component (e.g., my-component.component.ts) using the useIntlayer signal.

1. Declare Content

Create a content file using t() for translations. File: src/app/my-component/my-component.content.ts

import { t, type Dictionary } from "intlayer";

const content = {
  // The 'key' must be unique and matches what you pass to useIntlayer()
  key: "my-component",
  content: {
    text: t({
      en: "Welcome",
      fr: "Bienvenue",
      es: "Hola",
    }),
  },
} satisfies Dictionary;

export default content;

Setup

• Angular
• Angular 19
• Analog

Register provideIntlayer() in the providers of your ApplicationConfig (see the Angular guide).

useIntlayer Hook

In Angular, useIntlayer returns a Signal. You must call it as a function to access the value.

import { Component } from "@angular/core";
import { useIntlayer } from "angular-intlayer";

@Component({
  selector: "app-my-component",
  standalone: true,
  template: `
    <div>
      <h1>
        {{ content().text }}
      </h1>
      <img [src]="content().text.value" [alt]="content().text.value" />
    </div>
  `,
})
export class MyComponent {
  content = useIntlayer("my-component");
}

Compiler

The Intlayer Compiler can extract all your content keys from your components, using one CLI command (npx intlayer extract) or automatically at app build.
