Express route with dynamic arguments in the URL

Question

first of all i am a very beginner of Node so my question gonna be surely basic. So, i learn Node with a website and i am blocked on a one Express exercice. I need to create a route that accepts dynamic arguments in the URL path and responds with quote (object see after in code) from the proper author. The js is like follows :

var express = require('express');
var app = express();

var quotes = {
  'einstein': 'Life is like riding a bicycle. To keep your balance you must keep moving',
  'berners-lee': 'The Web does not just connect machines, it connects people',
  'crockford': 'The good thing about reinventing the wheel is that you can get a round one',
  'hofstadter': 'Which statement seems more true: (1) I have a brain. (2) I am a brain.'
};

app.get('/quotes/:name', function(request, response){
  response.send(request.params.name); /*And i'm blocked here*/
});
app.listen(8080);

Sorry, you're going to need to give me a bit more than that. What exactly is the issue, and what do you mean by you're blocked there? — southrop

the issue is that apparently i dont send the quoute in my response.send function — AlexDom

Well, that makes sense. You're just sending the value of the parameter :name in the response... — southrop

Your problem has nothing to do with Node, it's basic JavaScript. quotes[request.params.name]. — Ben Fortune

Yes Ben i've tried that too quotes[request.params.name] and quotes.request.params.name even quotes["request.params.name"] but it doesn't work — AlexDom

Try this for the line you're blocked at:

response.send(quotes[request.params.name]);

This is conditional on the :name being right though, so you may want to check it exists in your quotes object with Object.hasOwnProperty() first.

Doesn't seems to work, perhaps problem with browser i gonna try to restart exercise, who knows ;]

This is literally the code I put into my app.js and ran it, and it works fine for me.

seems it was browser, just last question, now they ask me to close the response and response.send(quotes[request.params.name]).end(); doesn't seems to please them -_-

Try doing response.end() on a separate line.

OK I found out (not really used a hint but who cares) it was response.end(quote)... Thanks southrop !
