# 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](https://intlayer.org/doc/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";
export const appConfig: ApplicationConfig = {
providers: [provideIntlayer()],
};
```
## 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;
}
```
## Localized Link component
Ensure your application's navigation respects the current locale by using a localized link. You can create a component or use a helper.
```typescript
import { Component, Input } from "@angular/core";
import { RouterModule } from "@angular/router";
import { useLocale } from "angular-intlayer";
import { getLocalizedUrl } from "intlayer";
@Component({
selector: "app-link",
standalone: true,
imports: [RouterModule],
template: `
<a [routerLink]="localizedHref()" [replaceUrl]="false">
<ng-content></ng-content>
</a>
`,
})
export class LinkComponent {
@Input() href: string = "";
private localeCtx = useLocale();
locale = this.localeCtx.locale;
localizedHref() {
return this.href.startsWith("http")
? this.href
: getLocalizedUrl(this.href, this.locale());
}
}
```
