Use maddy as an npm module for tighter integration with node apps (e.g. test fixtures). See the maddy documentation for usage: https://maddy.email/.
npm install maddy-dist
Put a maddy.conf in the current working directory.
import maddy from "maddy-dist";
const server = await maddy();
// You can also pass in a custom environment
const server = await maddy({
MY_VARIABLE: "www.example.org",
});
// And shut down when you are done
server.stop();
