How to reply from outside of the hapi.js route handler

Question

I have a hapi.js route where I want to defer the response. I\'ve tried storing the reply function and calling it later, or wrapping it in a promise, but hapi alway

Answer 1

If an error is thrown within your handler, hapi.js will immediately exit and give a 500 status code. Check if generateId() is a valid function.

The rest of your code looks right for your third and fourth examples. reply().hold() is necessary to keep the connection open after handler returns.

Answer 2

Since the version 8, Hapi supports Promised responses, so you can do :

var respond = function(message) {
    return new Bluebird.Promise(function(resolve, reject) {
        setTimeout(() => {
            resolve(message);
        }, 2000);
    });
};

server.route({
    method: 'GET',
    path: '/',
    handler: function (request, reply) {
        reply(respond("Hello buddy"));
    }
});
