# Intlayer Solid 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 Solid 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 Solid component (e.g., `MyComponent.tsx`) using the `useIntlayer` hook.

### Declare Content

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

- [Vite and Solid](references/environment_vite-and-solid.md)
- [SolidStart](references/environment_solid-start.md)
- [TanStack Start and Solid](references/environment_tanstack-start_solid.md)

## useIntlayer Hook

> [!IMPORTANT]
> In Solid, `useIntlayer` returns reactive content (e.g., `content`). You can access its properties directly.

```tsx
import { useIntlayer } from "solid-intlayer";

const MyComponent = () => {
  const content = useIntlayer("my-component");

  return (
    <div>
      <h1>
        {/* Return content */}
        {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.

## Compiler

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.
