00:00:00,150 --> 00:00:06,120
In this part, we would like to install a package called Express for our project, but why we need express

2
00:00:06,210 --> 00:00:11,310
and currently we write Order a culture of Dipen XHTML pages.

3
00:00:11,490 --> 00:00:16,560
And this is filed in this case because this is not a very complicated applications.

4
00:00:16,560 --> 00:00:23,830
But if we add more round handling more different requests and adding more server side logic, Dusko,

5
00:00:23,850 --> 00:00:27,240
we will become messy and hard to organize and express.

6
00:00:27,240 --> 00:00:32,820
It is a framework that helps us to manage our routing requests easily, including the surface ideologic,

7
00:00:32,820 --> 00:00:39,020
and responds in a more elegant way and the cook will become easier to read, update or extend.

8
00:00:39,930 --> 00:00:44,130
So let's go to the AMPM AstroCom and search for the Express.

9
00:00:44,310 --> 00:00:51,420
And on the Express page we can see how to install at this site and how to use it as well.

10
00:00:51,450 --> 00:00:59,010
And according to the documentation's, we can set the Express app by using this and setting up the routing

11
00:00:59,130 --> 00:01:00,180
like this.

12
00:01:00,340 --> 00:01:06,090
And what this does is it takes a callback function and sending a response on the world.

13
00:01:06,900 --> 00:01:12,150
And this is quite similar to the code that we did before at the previous letter.

14
00:01:12,150 --> 00:01:15,710
But you will see it is much easier to handle in this way.

15
00:01:15,840 --> 00:01:23,170
So let's first go to the terminal and type NPM I express.

16
00:01:24,330 --> 00:01:29,640
So when you back to the package Daltrey's on, you can see it already add to the dependencies.
