Intlayer Svelte 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 Svelte components that use them.

Workflow

To create a translated component, you need two files:

1. Declaration: A content file (e.g., myComponent.content.ts) defining the dictionary.
2. Implementation: A Svelte component (e.g., MyComponent.svelte) using the useIntlayer store.

1. Declare Content

Create a content file using t() for translations. File: src/components/MyComponent/myComponent.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

• SvelteKit
• Vite and Svelte

useIntlayer Hook

In Svelte, useIntlayer returns a store. You must use the $ prefix to access its value.

<script>
  import { useIntlayer } from "svelte-intlayer";
  const content = useIntlayer("my-component");
</script>

<div>
  <h1>
    {/* Return content */}
    {$content.text}
  </h1>
  {/* Return string (.value) */}
  <div aria-label={$content.text.value}></div>
</div>
