HTTP Middleware

In a proper production environment you can integrate with different packages and HTTP routers. Express A very basic middleware which timestamps the http request being handled could be written as:

var app = express()
var router = express.Router()

router.use(async function (req, res, next) {
   var message = sdk.message.FromString("My random data");
   try { await sdk.stamp(message) } catch(ignore) {};
   next();
});
