node.js multiple http requests

Question

I am a newbie to node and js and try to create a website in express that makes three Rest API calls before rendering the page. At the moment I have the below, which returns some json which I convert into a list of objects. Some of these properties only return id values and I would like to run three more API requests that return lookups on these Id's so that I can present this data to the user as meaningful values. I could do this synchronously by running the next API call where I am currently rendering the index page, but that looks really messy. All the async tutorials I have seen confuse the hell out of my newbie way of thinking though. Can someone post an easy to follow example for async that somewhat reflects the below structure? ``` var issues_json = ""; var request = http.request(options, function(response) { console.log("statusCode: ", res.statusCode); console.log("headers: ", res.headers); response.on("data", function(data) { issues_json += data; }); response.on("end", functio…

Accepted Answer

You should use Request

You would have something like

```
app.get("/route", function(req, res) {

var callbackThree = function(error, resp, body) {
    var data = JSON.parse(body);
    res.send({title; "My Title", data: data});
  }

var callbackTwo = function(error, resp, body) {
    request("api.com/42", callBackThree);
  }

var callbackOne = function(error, resp, body) {
    request("api.com/things", callBackTwo);
  }

request("api.com/users", callBackOne);
}
```
