Intlayer React 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 React 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 React component (e.g., MyComponent.tsx) using the useIntlayer hook.

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",
      // ... All other locales set in intlayer config file
    }),
  },
} satisfies Dictionary;

export default content;
