Node.js consumption of json from Rails app

Question

I have a json string (coming from my Rails app):

http://localhost:3000/employees/1.json

How do I get my Node.js app to consume this data?

This is the code I have in my Node.js app right now:

var employees = JSON.parse("http://localhost:3000/employees.json")

This is the error I'm getting:

prompt$ node app.js

node.js:201
        throw e; // process.nextTick error, or 'error' event on first tick
              ^
SyntaxError: Unexpected token h

If you visit http://localhost:3000/employees.json in your browser, do you get JSON in your browser or do you get an error? — RyanWilcox, Apr 13 '12 at 21:24

See this question:

Using Node.JS, how do I read a JSON object into (server) memory?

You should read the file first and then parse it.

var employees = JSON.parse(fs.readFileSync('employees.json', 'utf8'));

If for some reason your Rails app runs on some other machine, you need to make a http request for that. You could try this:

var site = http.createClient(port, host);

var request = site.request("GET", pathname, {'host' : host});
request.end();

request.on('response', function(response) {
  var json = '';

  response.on('data', function(chunk) {
    json += chunk;
  });

  response.on('end', function () {
    employees = JSON.parse(json);
  });
});

Okay, here is what confused me. The ('employees.json', 'utf8') part...I don't have a JSON file, I have a JSON string that can be accessed here: http://localhost:3000/employees/1.json – rzv Apr 15 '12 at 22:43
ok that means you have to communicate with your rails app with a http request, like I mentioned in the second approach. – mihai Apr 16 '12 at 08:54
