• javascript
• node.js
• stream
• hapi.js

• I'm not sure if you can. Does request support the streams2 api? From the hapi docs: Stream object (Note - any Stream object must be patible with the "streams2" API and not be in objectMode) hapijs./api#reply-interface – Clarkie Commented Jun 30, 2015 at 8:39
• 1 I've done it with the aws-sdk module: reply(s3.getObject(params).createReadStream()); – Clarkie Commented Jun 30, 2015 at 8:40
• server.route({ method: "*", path: "/api/results/{date}", handler: (req, reply) => { var fs = require('fs'); var fileStream = fs.createWriteStream('./doron'); request('google./doodle.png').pipe(fileStream); reply(fileStream); } }); this throwes the follwoing exception Debug: internal, implementation, error Error: Stream must have a streams2 readable interface – doron aviguy Commented Jun 30, 2015 at 11:12
• That's what I saw which is why I said that I don't think the request module supports streams2. You could try npmjs./package/wreck but I'm not sure if that'll work either. – Clarkie Commented Jul 1, 2015 at 8:07
• 1 ok i'll look into wreck , my problem now is that request module doesnt support streams2 . My opinion , is that hapi should support , and encourage people to use streams. after all my investigation i found there is not enough docs , about streams support in hapi . – doron aviguy Commented Jul 5, 2015 at 7:31

From another question/answer:

function (request, reply) {

    Request('http://example./image.png')
    .on('response', function (response) {
        reply(response);
     });
}

If you only need to forward an upstream response, you can just use a proxy handler via the h2o2 plugin:

server.route({
    method: 'GET',
    path: '/upstream/file',
    handler: {
        proxy: {
            uri: 'http://example./image.png'
        }
    }
});
