49 00:03:20,790 --> 00:03:22,140 Well, we want to get the package. 50 00:03:22,530 --> 00:03:27,510 We dot the entry because we want to have access to those environmental variables, correct? 51 00:03:27,930 --> 00:03:30,180 Now the packages already installed. 52 00:03:30,450 --> 00:03:33,330 So if you take a look at the package JSON, we scroll up. 53 00:03:33,540 --> 00:03:34,410 Check it out. 54 00:03:34,410 --> 00:03:35,570 We have got it right. 55 00:03:36,060 --> 00:03:37,200 So let's navigate back. 56 00:03:37,710 --> 00:03:41,340 We're looking for the data entry, so let's just require it. 57 00:03:41,970 --> 00:03:43,410 Then let's go with the package name. 58 00:03:43,410 --> 00:03:48,510 Got the entry and then we want to go with config and we want to invoke it. 59 00:03:48,990 --> 00:03:50,150 Let's save it here. 60 00:03:50,220 --> 00:03:52,020 We want to restart the server. 61 00:03:52,920 --> 00:03:56,040 So it's where everything npm start. 62 00:03:56,520 --> 00:04:03,570 And then if everything is correct, right, we should see Server is listening on Port 5000 now. 63 00:04:03,570 --> 00:04:05,850 Lastly, we mentioned that for this project. 64 00:04:06,770 --> 00:04:14,570 We're going to use the Mongoose six, so as I was recording the project, as I already mentioned in 65 00:04:14,570 --> 00:04:15,390 the previous videos. 66 00:04:15,770 --> 00:04:17,810 Mongoose came out with version six. 67 00:04:18,360 --> 00:04:22,130 And the good news is that there's not much that we need to change. 68 00:04:22,400 --> 00:04:28,640 The only thing with Mongoose six is the fact that we don't need to add these deprecation warnings. 69 00:04:28,820 --> 00:04:34,610 In fact, if you will, if you add those deprecation warnings, then it's just going to spit some warnings 70 00:04:34,820 --> 00:04:35,600 in the council. 71 00:04:35,960 --> 00:04:43,490 So since I'm using Mongoose six, we don't need them and we simply can't get the function, invoke it 72 00:04:43,940 --> 00:04:45,080 and we're good to go. 73 00:04:45,620 --> 00:04:49,370 And once we have this in place, we can move on to the next step.
