# nextmail.languages

Every method in this namespace: its signature, its parameters, what it returns and an example.

## Methods

Every language a translated send or preview accepts.

### `nextmail.languages.list()`

List every language a message can be sent in

```ts
list(options?: RequestScope): Promise<Array<LanguageResource>>
```

Returns the whole language table in one response, with no cursor. It sits behind a key like every other endpoint but needs no scope, because it names no data belonging to anybody. The table is around two hundred rows and changes a handful of times a year, so fetch it once and keep it.

The order is meaningful. The languages people are most likely to be emailed in come first, then regional variants, then the rest by region. A picker should render the rows in the order they arrive until somebody types, then search `native`, `label` and `code` together. Show `native` first, since it is the word someone looking for their own language is scanning for, and never show `flag` on its own: a flag names a country, not a language.

Any row's `code`, `label` or `native` is accepted by `translate.to` on `emails.send` and by `emails.translate`. The package also ships the same table as `LANGUAGES` with `resolveLanguage`, which is useful before the first request, while this call returns the server's current rows.

**Parameters**

- `options.signal` (`AbortSignal`): Cancels the request.
- `options.apiKey` (`string`): Authenticates this call with a different key.

**Returns**

`Array<LanguageResource>`, each with `code` (BCP-47), `label` (English name), `native` (endonym), `flag` and `rtl`.

**Example**

```ts
const languages = await nextmail.languages.list()

const german = languages.find((language) => language.code === 'de')

console.log(german?.native, languages.filter((language) => language.rtl).length)
```

**Notes**

- `rtl` marks right-to-left targets. A translated body for one of them is wrapped in `dir="rtl"` before it is sent.
- The bundled `LANGUAGES` table can lag the server by however old your installed package is, so prefer this call when a newly added language matters.
