# 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`
```typescript
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](references/environment_angular.md)
-
- ### Intlayer Provider
-
- To use Intlayer in your Angular application, you need to add the `provideIntlayer` provider to your application configuration.
-
- ```typescript
- import { ApplicationConfig } from "@angular/core";
- import { provideIntlayer } from "angular-intlayer";
+ - [Angular 19](references/environment_angular_19.md)
+ - [Analog](references/environment_analog.md)
- export const appConfig: ApplicationConfig = {
- providers: [provideIntlayer()],
- };
- ```
+ Register `provideIntlayer()` in the `providers` of your `ApplicationConfig` (see the [Angular guide](references/environment_angular.md)).
## useIntlayer Hook
In Angular, `useIntlayer` returns a **Signal**. You must call it as a function to access the value.
```typescript
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");
}
```
- ## Change language
-
- To change the language, use the `setLocale` function from the `useLocale` hook.
-
- ```typescript
- import { Component } from "@angular/core";
- import { useLocale } from "angular-intlayer";
- import { Locales } from "intlayer";
-
- @Component({
- selector: "app-locale-switcher",
- standalone: true,
- template: `
- <button (click)="setLocale(Locales.FRENCH)">
- Change Language to French
- </button>
- `,
- })
- export class LocaleSwitcherComponent {
- Locales = Locales;
- private localeCtx = useLocale();
- setLocale = this.localeCtx.setLocale;
- }
- ```
+ ## Compiler
- ## Localized Link component
+ The [Intlayer Compiler](references/compiler.md) can extract all your content keys from your components, using one CLI command (`npx intlayer extract`) or automatically at app build.
- Ensure your application's navigation respects the current locale by using a localized link. You can create a component or use a helper.
