Native TypeScript without compilation config
Deno 2.0 runs TypeScript files out of the box with zero build step, zero Babel/Webpack configuration, and built-in security permissions.
Complete Deno 2.0 Email Server (server.ts)
Using the web-standard Deno.serve API, spin up an instant transactional email dispatch worker.
TYPESCRIPT
Deno.serve(async (req: Request) => {
if (req.method !== 'POST') {
return new Response('Method Not Allowed', { status: 405 });
}
const { to, subject, message } = await req.json();
const apiKey = Deno.env.get('SADASEND_API_KEY');
const res = await fetch('https://api.sadasend.com/v1/emails', {
method: 'POST',
headers: {
'Authorization': `Bearer ${apiKey}`,
'Content-Type': 'application/json',
},
body: JSON.stringify({ to, subject, text: message }),
});
const data = await res.json();
return Response.json(data, { status: res.status });
});Running with explicit network permissions
Deno requires explicit permission flags: deno run --allow-net=api.sadasend.com,0.0.0.0 --allow-env server.ts
