Express configure doesn't work - express

Question

I use
app.configure( function(){
app.use(express.static(__dirname, '/'));
});
then I figured out it's the old version. Then I used this,
var env = process.env.NODE_ENV || 'development';
if ('development' == env) {
app.use(express.static(__dirname, '/'));
}
but it still give me errors. My whole code is below.
var express = require('express'),
app = express();
var env = process.env.NODE_ENV || 'development';
if ('development' == env) {
app.use(express.static(__dirname, '/'));
}
app.get('/people/:id', function(req, res){`
var customerId = parseInt(req.params.id);
var data = {};
for(var i = 0; i < people.length; i++){
if(people[i].id === customerId){
data = people[i];
break;
}
}
res.json(data);
});
app.get('/people', function(req, res){
res.json(people);
});
app.lisen(8080);
console.log('Listening on express port 8080');
var people = [
{id: 1, name: 'John', city: 'Lisbon', gender: 'male', total: '515.561',
orders: [
{id: 1, product: 'Shoes', total: '100'}
]
},
{id: 2, name:'Abbie', city:'Orlando', gender:'female', total:'3445.34',
orders: [
{id: 2, product: 'Shoes', total: '200.561'}
]
},
{id: 3, name:'Will', city:'Houston', gender:'female', total:'98754.00',
orders: [
{id: 1, product: 'Shoes', total: '300.561'},

]
},

{id: 6, name:'Agulera', city:'Orlando', gender:'female', total:'3445.34',
orders: [

},

}

I'm quite new to express and I'm doing this by watching a video. so I want to configure it properly and run it. Please help me with this.

Answer 1

spelling error
app.lisen(8080);
--->
app.listen(8080);
second...
global variables are bad strategy, put the var people as a local variable of app:
http://expressjs.com/api.html#app.locals
app.locals.people = "put the people data here";
Lastly, you should put responses and relevant http error codes to diagnose where there are errors:
for example.....
var yes = "yes";
if ( yes !== data.answer) {
console.log(err);
res.status(401).send(err + "error, you do not have authorized access to this data"); }
else {
console.log("success! You are authorized!")
res.status(200).send(data);
};
Sends back json object data and "ok" status code if condition is met;
status codes:
