1 00:00:00,390 --> 00:00:06,450 And before we go any further, let's address the elephant in the room, why jazz is so slim. 2 00:00:07,050 --> 00:00:13,590 You see, while I'm a big fan of reusing the code, especially for smaller projects, in my opinion, 3 00:00:13,590 --> 00:00:21,510 at some point it's also very useful to reiterate why and how we're doing something just so we're comfortable 4 00:00:21,510 --> 00:00:24,780 doing that when we need to start working on our own project. 5 00:00:25,530 --> 00:00:31,350 Now, since Course has quite a few projects, in my opinion, it would be very annoying and redundant 6 00:00:31,740 --> 00:00:33,990 if we would do that in every project. 7 00:00:34,590 --> 00:00:38,010 But while building bigger project, I think it's very useful. 8 00:00:38,520 --> 00:00:43,860 Also, while we're setting everything up, basically while we work on the stuff we already have covered 9 00:00:44,250 --> 00:00:50,970 in some shape or form, I will share two steps I'm about to take and I highly encourage you to stop 10 00:00:50,970 --> 00:00:55,140 the video and try to implement the functionality yourself first. 11 00:00:55,650 --> 00:01:02,070 That way, you'll get more comfortable with a setup when you need to start working on your own project. 12 00:01:02,340 --> 00:01:05,519 Now, let me be very clear, though this does not. 13 00:01:05,519 --> 00:01:09,840 It does not mean that you need to start every project from scratch. 14 00:01:10,350 --> 00:01:17,940 There's the reason why we set up reusable code and basically drag from project to project, but especially 15 00:01:17,940 --> 00:01:18,810 in the beginning. 16 00:01:19,260 --> 00:01:23,700 While you're still iffy about some stuff, it's very useful to repeat some steps. 17 00:01:24,150 --> 00:01:24,630 All right. 18 00:01:25,050 --> 00:01:31,170 And once I'm done with my painful one person Broadway edition, let's get to work and surprise surprise. 19 00:01:31,710 --> 00:01:35,940 I'll start everything by setting up a basic express server. 20 00:01:36,450 --> 00:01:38,880 So here are steps that I want you to take. 21 00:01:39,210 --> 00:01:39,600 First. 22 00:01:41,030 --> 00:01:46,120 In Port Express and a senator, the variable, I remember there was that middle step where we need to 23 00:01:46,300 --> 00:01:50,480 invoke Express when set up a port variable. 24 00:01:50,800 --> 00:01:53,920 And in this case, we'll be listening for Port 5000. 25 00:01:54,570 --> 00:02:01,030 And it's going to make sense a little bit later, as well as set up a start function where you'll be 26 00:02:01,030 --> 00:02:05,020 listening on that port for incoming requests. 27 00:02:05,350 --> 00:02:07,960 So stop the video, try to implement yourself. 28 00:02:08,440 --> 00:02:11,050 And once you're ready to go, hit play. 29 00:02:11,800 --> 00:02:12,220 All right. 30 00:02:12,550 --> 00:02:16,950 Hopefully, everything went as expected, so I'm going to go to our progress. 31 00:02:17,410 --> 00:02:23,320 I'll remove my lovely console.log and we'll start by getting the expression, so I'll just set up a 32 00:02:23,320 --> 00:02:23,800 comment. 33 00:02:23,800 --> 00:02:28,270 Express concern expressed is equal to your acquire. 34 00:02:29,210 --> 00:02:36,910 And we're looking for express package one to remember, we need to add a step where there is a variable 35 00:02:37,340 --> 00:02:43,220 in most cases is going to be apt, but again, this is really up to you when we invoke, Express and 36 00:02:43,220 --> 00:02:47,750 now we have all the express functionality in our app variable. 37 00:02:48,050 --> 00:02:55,100 When we want to go with start function or can't start, it's going to be async since eventually we'll 38 00:02:55,100 --> 00:02:56,750 also have our connectivity. 39 00:02:57,020 --> 00:02:59,360 But for time being, doesn't really matter. 40 00:02:59,750 --> 00:03:01,940 Van, we'll set up a track again. 41 00:03:02,330 --> 00:03:09,260 This is for our database connection, but for the time being, we just want to go with app back and 42 00:03:09,260 --> 00:03:09,620 listen. 43 00:03:10,190 --> 00:03:15,080 Now, before I go any further, I need to go and check that I imported Express. 44 00:03:15,110 --> 00:03:16,010 Okay, that's good. 45 00:03:16,500 --> 00:03:18,020 But I didn't set up the variable. 46 00:03:18,440 --> 00:03:24,950 So before I go any further, we go with concert and this is going to be equal to the fourth round. 47 00:03:24,950 --> 00:03:28,310 We're looking for process and unity. 48 00:03:29,000 --> 00:03:37,070 And of course, the variable is support now if it's not available and we're going to go for 5000, which 49 00:03:37,070 --> 00:03:39,260 is going to be our basic setup while developing. 50 00:03:39,620 --> 00:03:43,220 And now I can go back to start where I have app about. 51 00:03:43,220 --> 00:03:43,640 Listen. 52 00:03:43,910 --> 00:03:45,110 So that was the method. 53 00:03:45,560 --> 00:03:47,330 Then we need to provide a port. 54 00:03:47,720 --> 00:03:50,780 So of course, this is going to be the variable now report one. 55 00:03:51,260 --> 00:03:55,670 And let's also right away at a console log that we're listening on that board. 56 00:03:55,670 --> 00:04:02,000 So console log of may remove the code one here and we're going to go with template strings instead. 57 00:04:02,420 --> 00:04:03,540 Since I want to print out. 58 00:04:03,860 --> 00:04:05,270 Well, what is the port variable? 59 00:04:05,630 --> 00:04:07,640 So we're going to go with server is listening. 60 00:04:09,590 --> 00:04:16,070 And we're going to add port and let's access the port of entry, but let's add something about that 61 00:04:16,070 --> 00:04:18,589 is just my preference and as far as the error. 62 00:04:19,190 --> 00:04:24,500 Well, let's just go with log and let's console.log the error. 63 00:04:24,830 --> 00:04:32,750 And if everything is correct, once we start up the function, we should see server is listening on 64 00:04:32,750 --> 00:04:33,710 port five thousand. 65 00:04:34,310 --> 00:04:37,670 And since I do now, I can move on to the next task.
