00:00:03,010 --> 00:00:06,280
Welcome to section number seven on web servers.

2
00:00:06,280 --> 00:00:11,800
So far in the class all of the applications we've created have only been accessible via the command

3
00:00:11,800 --> 00:00:12,420
line.

4
00:00:12,430 --> 00:00:17,140
Now that is a great way to get started but it's not realistic for users.

5
00:00:17,140 --> 00:00:22,570
It would be much better if a user could simply Type A you are all in the browser to pull up and interact

6
00:00:22,570 --> 00:00:24,040
with our applications.

7
00:00:24,100 --> 00:00:29,170
And that is exactly what we're going to start to work towards in this section in this section you'll

8
00:00:29,170 --> 00:00:33,400
be learning about one of the most popular NPM libraries out there.

9
00:00:33,400 --> 00:00:40,380
That is Express Express makes it really easy to create web servers with note these servers are going

10
00:00:40,380 --> 00:00:44,620
to allow us to serve up all of the assets for our web application.

11
00:00:44,620 --> 00:00:50,890
This includes H2 UML we're going to render to the screen see SS to style our application and client

12
00:00:50,890 --> 00:00:57,040
side JavaScript so we can set up all sorts of awesome user interaction now using Express.

13
00:00:57,040 --> 00:01:00,310
We're also going to be able to serve up Jason data.

14
00:01:00,310 --> 00:01:06,190
That's what's going to allow us to get the location from the user convert it into a forecast and then

15
00:01:06,190 --> 00:01:10,720
send the forecast back to the browser to have it rendered to the screen.

16
00:01:10,720 --> 00:01:15,880
Now that's a lot of stuff but don't worry as always we're going to cover all of that in detail step

17
00:01:15,940 --> 00:01:17,230
by step.

18
00:01:17,230 --> 00:01:23,380
Now most courses start here with express but I think that's a rough way to go getting started with the

19
00:01:23,380 --> 00:01:25,600
fundamentals of node is important.

20
00:01:25,600 --> 00:01:30,750
Otherwise it can be hard to differentiate between what is node and what is Express.

21
00:01:30,850 --> 00:01:35,980
Now that you're already familiar with the fundamentals of node it's going gonna be so much easier to

22
00:01:35,980 --> 00:01:38,140
learn and master Express.

23
00:01:38,170 --> 00:01:39,670
Let's go ahead and jump right in.
