create-send16

Bootstrap a Send16-powered email setup in any project — zero pasted keys, no manual configuration.

npx create-send16

That's it. The CLI will:

1. Detect your framework (Next.js / Astro / Remix / SvelteKit / Nuxt / Hono / Express / Vite + React / plain Node).
2. Open your browser to authorize (or sign you in if you don't have an account yet).
3. Write SEND16_API_KEY to .env.local.
4. Drop a typed lib/send16 module and a working example route in the right place for your stack.

You'll be sending email in under a minute.

What gets created

For Next.js (App Router):

lib/send16.ts                            # const send16 = new Send16()
app/api/send-example/route.ts            # GET that sends one email and returns its id
.env.local                               # SEND16_API_KEY=sk_live_…

(Equivalent idiomatic files for every other supported framework — Pages Router gets pages/api/, Remix gets app/routes/api.send-example.ts, SvelteKit gets src/routes/api/send-example/+server.ts, etc.)

Flags

| Flag | What it does | |---|---| | --no-scaffold | Auth + write .env.local only. No example files. |

Manual install

If npx isn't an option (corporate proxy, locked-down CI), you can install the SDK directly:

npm install send16-mail

Then create an API key at https://send16.com/dashboard/developers and set SEND16_API_KEY in your environment. The starter file content from this CLI is also documented at https://send16.com/docs/quickstart.

Security

create-send16 uses an OAuth-style device-authorization flow (RFC 8628, the same pattern as gh auth login). Your laptop never sees your password; we never see your existing API keys. We mint a fresh, scoped key labeled after the device (create-send16 / your-laptop / darwin) — you can revoke it from the dashboard at any time.

The minted key is returned to your terminal exactly once and never stored on Send16's servers in plaintext afterwards.
