# METHOD_NAME_ALL_LOWERCASE

**Kind:** Constant

**Source:** [`src/router.ts`](https://github.com/honojs/hono/blob/main/src/router.ts#L13)

Constant representing all HTTP methods in lowercase.

`METHOD_NAME_ALL_LOWERCASE` stores the lowercase method token for routes that match all HTTP methods. Router code can pass or compare this token when registering method-agnostic routes.

## Definition

```ts
'all' as const
```

## Value

```ts
'all' as const
```

## Usage

```ts
import { METHOD_NAME_ALL_LOWERCASE } from './router'

router.add(METHOD_NAME_ALL_LOWERCASE, '/health', (context) => {
  return context.text('OK')
})
```

## AI Coding Instructions

- Use `METHOD_NAME_ALL_LOWERCASE` instead of hardcoding the `all` method token.
- Pass this constant to router registration code when a route should match any HTTP method.
- Keep lowercase and uppercase method tokens distinct when comparing router method values.
- Check router matching behavior before changing how all-method routes are registered.
