intlayer: Skill for Claude Code

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;

Setup

• Vite and React
• Create React App
• React Router v7
• Tanstack Start
• React Native and Expo
• Lynx and React
• Storybook

useIntlayer Hook

import { useIntlayer } from "react-intlayer";
const MyComponent = () => {
  const content = useIntlayer("my-dictionary-key");
  return (
    <div>
      <h1>
        {/* Return react node */}
        {content.text}
      </h1>
      {/* Return string (.value) */}
      <img src={content.text.value} alt={content.text.value} />
    </div>
  );
};

Bundle Optimization

Read content fields by name (dot access or destructuring) so the build can purge and minify the dictionary. Never index content at runtime (content.statuses[status], use select()), and call useIntlayer in each child component instead of passing content as a prop. See the intlayer-bundle-optimization skill.
