Transactional email for Lunora. Render TSX templates, send through Cloudflare Email Workers (the default) or the Resend adapter, and offload delivery to a Cloudflare Queue so requests return immediately. In `lunora dev` every send is captured into the studio's Mail inbox instead of hitting a provider.
Part of the [Lunora](https://github.com/anolilab/lunora) framework — a type-safe, real-time backend on Cloudflare Workers + Durable Objects with a Vite-first DX.
## Install
```sh
npm install @lunora/mail
```
```sh
yarn add @lunora/mail
```
```sh
pnpm add @lunora/mail
```
## Usage
Build a `Mailer` and send. `createMailer` needs `from` plus one transport: the
default is Cloudflare Email Workers (`cloudflareSend`), with Resend (`apiKey`) as
a bring-your-own-provider option. Pass a React Email element through `react` and
it renders to `html` + `text` for you (this file must be `.tsx`):
```tsx
import { createMailer } from "@lunora/mail";
import { WelcomeEmail } from "./emails/Welcome";
const mailer = createMailer({
apiKey: env.RESEND_API_KEY,
from: "Acme ",
});
await mailer.send({
to: "alice@example.com",
subject: "Welcome",
react: ,
});
```
In a Worker, `createMailerFromEnv(env)` is usually what you want: it reads
`MAIL_FROM`, captures into the studio inbox in dev, and otherwise delivers via
the `SEND_EMAIL` binding (or `RESEND_API_KEY`).
> This README covers the basics. For the full API, options, and guides, see the **[documentation](https://lunora.sh/docs/packages/mail)**.
