1 00:00:00,590 --> 00:00:10,730 Less initialize our projects as NPM because we want to use third party packages like Express Mongoose 2 00:00:10,730 --> 00:00:12,110 and many more. 3 00:00:12,320 --> 00:00:19,640 So for this I'm going to use the built in terminal that came with Visual Studio Code and you can use 4 00:00:19,640 --> 00:00:21,320 any terminal of your choice. 5 00:00:21,320 --> 00:00:24,670 So I'm going to open that by clicking on terminal. 6 00:00:24,680 --> 00:00:26,540 And here we go. 7 00:00:26,930 --> 00:00:35,060 The first command is called NPM init and for this I can give it a flag for yes. 8 00:00:35,150 --> 00:00:41,390 And this one going to give me the default configuration and I can override them. 9 00:00:41,390 --> 00:00:48,260 So let's hit enter and you can see that this had the configuration that it has given to me. 10 00:00:48,590 --> 00:00:57,110 The first property is called name, and it took the name of the folder that I use, the version of my 11 00:00:57,110 --> 00:01:04,760 project, the description, and then the main file it used the server to file because that is what I 12 00:01:04,790 --> 00:01:06,050 created here. 13 00:01:06,440 --> 00:01:09,980 And then the next property is called the script. 14 00:01:09,980 --> 00:01:18,940 So let's open the package JSON file and you can see that we have additional file called package the 15 00:01:18,980 --> 00:01:20,150 JSON file. 16 00:01:20,150 --> 00:01:24,380 And this is the same as I was showing you in the terminal. 17 00:01:24,470 --> 00:01:29,990 So for the description, I can give this one as Foo stock. 18 00:01:31,660 --> 00:01:33,460 Blog application. 19 00:01:34,140 --> 00:01:41,400 And then the main for this one, if your file is up and you couldn't pick it up, you can change this 20 00:01:41,400 --> 00:01:48,990 one to server or app or index, but make sure that it's used the same name as your file. 21 00:01:48,990 --> 00:01:56,070 And then this one going to be the script and this one going to contain the script for running our application. 22 00:01:56,070 --> 00:02:01,620 And even in deployment, it's going to use a script here to start our server. 23 00:02:02,070 --> 00:02:11,190 And for key words, if we want to improve the process, we can put your keywords here as block and then 24 00:02:11,190 --> 00:02:15,690 comma, I would say Node.js and many more. 25 00:02:15,810 --> 00:02:23,760 And then the author for this project, I'm going to use my school name as I never take academic. 26 00:02:24,090 --> 00:02:28,260 And then four Line says, I would like to use this one. 27 00:02:28,350 --> 00:02:32,190 All right, so this is a package JSON file. 28 00:02:32,190 --> 00:02:40,020 So what is it where, as the name implies, it's going to use to manage the packages for our application. 29 00:02:40,260 --> 00:02:45,210 The next step is that let's install the packages that we may need. 30 00:02:45,210 --> 00:02:47,200 So back to the terminal. 31 00:02:48,110 --> 00:02:50,730 And I'm going to install these packages. 32 00:02:50,750 --> 00:02:57,910 So for now, I would like to install Xpress and Mongoose for now. 33 00:02:57,990 --> 00:02:59,480 I'm going to hit enter. 34 00:03:00,970 --> 00:03:01,660 All right. 35 00:03:01,660 --> 00:03:04,450 These two packages have finished in Sterling. 36 00:03:04,450 --> 00:03:08,200 So let's go ahead and start to create our server. 37 00:03:08,230 --> 00:03:14,350 So first step is I'm going to require the express package as that. 38 00:03:14,350 --> 00:03:18,340 And for this, we are going to use common way. 39 00:03:18,670 --> 00:03:27,460 The next step is that I'm going to initiate the instance of the Express as AB is equal to express. 40 00:03:27,670 --> 00:03:35,200 So this line of code simply means that I am calling the function given to us by experts and assigned 41 00:03:35,200 --> 00:03:37,180 to a variable called AB. 42 00:03:37,480 --> 00:03:45,580 So for this, if I console log AB, I'm going to have all the properties that has given to us by experts. 43 00:03:45,610 --> 00:03:53,110 Let me open the terminal again and to run this file we are going to use Node and then the name of the 44 00:03:53,110 --> 00:04:02,860 file, which server dot G is going to be our server dot G s and you can see all the methods and functions 45 00:04:02,860 --> 00:04:08,050 and properties given to us by Express to make our life easier. 46 00:04:08,140 --> 00:04:14,830 So on the app, we have couple of methods, for example, to be able to create a server. 47 00:04:14,980 --> 00:04:20,920 So let's have some comment here and then we're going to fill them up as we move on. 48 00:04:31,630 --> 00:04:36,940 So for the meantime, we are going to work on the listening to server. 49 00:04:36,970 --> 00:04:41,170 So the first one is I need to create what is called port. 50 00:04:41,170 --> 00:04:46,660 And this simply means what number is our application is going to listen to. 51 00:04:46,750 --> 00:04:53,170 And for this we are going to use what is called process dot, EMV, dot port. 52 00:04:53,170 --> 00:04:59,860 And then if there is no value on the port, then we are going to use 9000. 53 00:05:00,070 --> 00:05:03,460 The next step is that we are going to listen to the server. 54 00:05:03,460 --> 00:05:10,750 So on the app we have a method called Listen and in here our pass in the port, then this one going 55 00:05:10,750 --> 00:05:18,310 to be the callback function is going to be as console log and I will say that server. 56 00:05:19,820 --> 00:05:21,170 Is running. 57 00:05:26,350 --> 00:05:30,040 On parts and I'm going to inject the port. 58 00:05:30,040 --> 00:05:35,680 So let me use backtrack here and backtrack also here and here. 59 00:05:35,740 --> 00:05:39,850 Going to be a dollar sign carry basis and then the port. 60 00:05:40,300 --> 00:05:45,700 The next step is that I need to configure the script to run the application. 61 00:05:45,700 --> 00:05:51,280 And you can see here that we have additional properties being added called dependencies. 62 00:05:51,280 --> 00:05:55,660 For now we are using two dependencies for our application. 63 00:05:55,660 --> 00:06:01,660 So we inside the script, we are going to maintain this one because you may need this one if you deploy 64 00:06:01,660 --> 00:06:09,160 your application and going to use this keyword core start and use node to start our server, but we 65 00:06:09,160 --> 00:06:12,550 don't want to restart our server any time we make changes. 66 00:06:12,550 --> 00:06:20,380 Because of that, we are going to install a third party package for Node one and this is going to help 67 00:06:20,380 --> 00:06:23,680 us to restart the application automatically. 68 00:06:23,680 --> 00:06:26,670 Any time we make changes, we're going to be empty. 69 00:06:26,680 --> 00:06:28,540 Am I? 70 00:06:28,540 --> 00:06:35,800 And then the name going to be Node one and I'm going to install this one as dev dependencies and I'm 71 00:06:35,800 --> 00:06:37,360 going to give it to DE. 72 00:06:37,870 --> 00:06:44,770 Now no one has finished installing, so let me close this one and inside here I'm going to use what 73 00:06:44,770 --> 00:06:46,180 is called server. 74 00:06:47,260 --> 00:06:48,680 The name is up to you. 75 00:06:48,700 --> 00:06:51,260 You can name it whatever you want by here. 76 00:06:51,280 --> 00:06:53,680 I want to pass in two agreements. 77 00:06:53,710 --> 00:06:55,810 The first one is called Not. 78 00:06:56,320 --> 00:07:01,150 And then the file that you want to run, which is server towards cheese. 79 00:07:01,750 --> 00:07:05,320 So next step is that let's run the application. 80 00:07:05,320 --> 00:07:10,750 So let's open a terminal by making use of NP run server. 81 00:07:12,400 --> 00:07:17,360 And you can see that my server is listening on Port 9000. 82 00:07:17,380 --> 00:07:26,320 Before we end this video, you can see that I have two files called package that log dot JSON and then 83 00:07:26,320 --> 00:07:28,690 the package JSON file. 84 00:07:28,720 --> 00:07:35,620 I have this to file because I'm using two package managers and that is John and NPM. 85 00:07:35,620 --> 00:07:37,420 So I'm going to remove this one. 86 00:07:38,150 --> 00:07:43,160 Because an application needs only one package JSON file. 87 00:07:43,190 --> 00:07:49,160 Now that we have our server up and running in this video, let's go ahead and connect application to 88 00:07:49,160 --> 00:07:50,210 MongoDB.
