How to get the data from a node read stream to use it for a HTTP post request?

Question

I'd like to send an HTTP post request using the scoped-http-client, like this:

client('http://url-to-post-to.com/').post({filedata: <data from stream>})

How would I pass in the data of a node stream?

Answer 1

From their documentation, you can get access to the http.ClientRequest which is a writable stream. From there, you can just pipe the file data to the request. For example, if you were to send JSON file data:

var fs = require("fs"),
    scopedClient = require("scoped-http-client");

var file = fs.createReadStream("./test.json");

var client = scopedClient.create("http://url-to-post-to.com/").header("Content-Type", "application/json");

client.post(function(err, req) {
    file.pipe(req);
});
