# intlayer Hono Middleware Documentation

The `intlayer` middleware for Hono detects the user's locale and populates the context object with Intlayer functions. It also enables the use of global translation functions within the request context.

## Usage

```ts
import { Hono } from "hono";
import { intlayer } from "hono-intlayer";

const app = new Hono();

app.use("*", intlayer());

app.get("/", async (c) => {
  const t = c.get("t");
  const content = t({
    en: "Hello",
    fr: "Bonjour",
  });

  return c.text(content);
});
```

## Description

The middleware performs the following tasks:

1. **Locale Detection**: It analyzes the request (headers, cookies, etc.) to determine the user's preferred locale.
2. **Context Population**: It adds Intlayer data to the Hono context, accessible via `c.get()`. This includes:
   - `locale`: The detected locale.
   - `t`: A translation function.
   - `getIntlayer`: A function to retrieve dictionaries.
   - `getDictionary`: A function to process dictionary objects.
