WEBVTT 00:03.760 --> 00:05.110 Hey, did everyone are they sure? 00:05.110 --> 00:06.640 And welcome to another video. 00:06.670 --> 00:09.550 In the previous video, we saw that how we can use the sign up. 00:09.550 --> 00:13.420 And I did a classic mistake up here, the comma instead of the dot. 00:13.420 --> 00:15.790 So not the dot, it should be a comma. 00:15.790 --> 00:20.980 And again, the good thing is I don't have to just check this mistake into five different files since 00:20.980 --> 00:22.540 I have broken down the cookie token. 00:22.540 --> 00:25.570 Luckily for me, I can just change it and hopefully this should work. 00:25.570 --> 00:30.130 So this is one typo that we have done in this video we're going to work through and we'll connect our 00:30.130 --> 00:30.700 database. 00:30.700 --> 00:32.290 So that's going to be basics of it. 00:32.290 --> 00:33.700 So let's go ahead and do that. 00:33.760 --> 00:38.110 Now for the database connection, I would like to have the database URL as well. 00:38.140 --> 00:40.060 So let's go ahead and connect this one. 00:40.060 --> 00:42.790 So I'll call this one as simply DB, underscore URL. 00:42.790 --> 00:46.540 Feel free to name these variables, whatever you like, it doesn't really matter. 00:46.780 --> 00:47.440 Nothing at all. 00:47.440 --> 00:48.910 So let's go ahead and call this one. 00:48.910 --> 00:57.700 So this one is going to be MongoDB Colon, slash, slash, and then we need to go ahead and 1 to 7 .0.0.1 00:58.000 --> 01:05.620 and then we have to grab a port as well, which is 27017 and what should I call our DB? 01:05.620 --> 01:13.960 Let's go ahead and call this one as ae d shirt store because I might be having a couple of other DBAs 01:13.960 --> 01:14.230 as well. 01:14.230 --> 01:16.540 So I think this long I didn't I don't have it. 01:16.540 --> 01:18.340 So let's go ahead and grab this one up here. 01:18.340 --> 01:23.620 So this is the basic again, in case your URL of the DB, you are using the atlas or something, just 01:23.620 --> 01:26.380 go ahead and inject that URL as simple as it sounds. 01:27.240 --> 01:32.220 Once I have this one, all it remains is to connect the database and to see that where I'm going to 01:32.220 --> 01:33.300 inject that functionality. 01:33.300 --> 01:34.920 We have done that once in the past as well. 01:34.920 --> 01:37.410 Let's go into the config and create a new file. 01:37.410 --> 01:40.860 This file will be simply DB JS because that's exactly what it does. 01:40.860 --> 01:42.780 It just connects with the database itself. 01:42.900 --> 01:45.780 In order to connect with the database, we are going to need a mongoose. 01:45.780 --> 01:47.640 So let's go ahead and require that. 01:48.090 --> 01:49.950 Require there we go. 01:49.950 --> 01:51.810 And we're going to say mongoose. 01:52.230 --> 01:56.400 The mongoose has a simple functionality of connecting with the database, but we won't be holding it 01:56.400 --> 01:56.910 like that. 01:56.910 --> 02:02.490 We will be holding that into a method itself, and we'll be throwing this method out from this config 02:02.490 --> 02:04.890 and will be importing that into index or JS. 02:04.890 --> 02:11.820 So let's go ahead and say that and we're going to call this one as Connect with DB. 02:12.660 --> 02:15.990 And there we go, nice and easy, just like that. 02:17.640 --> 02:19.680 Now obviously this method needs to be thrown out. 02:19.680 --> 02:25.140 So we're going to go ahead and say module dot x sports and let's go ahead and say connect with DB. 02:25.350 --> 02:29.190 Now, inside this one, all we got to do is connect with the database itself. 02:29.190 --> 02:30.600 So let's go ahead and do that. 02:30.720 --> 02:35.610 Now, Mongoose can actually connect with the database by simply throwing a property of Dot Connect. 02:35.610 --> 02:36.420 Now here it is. 02:36.420 --> 02:41.400 It will be definitely be able to connect there, but there might be things that can go wrong or things 02:41.400 --> 02:42.270 that can go right. 02:42.270 --> 02:48.120 So obviously after the connection, you can actually go ahead and chain on a dot then and a dot catch 02:48.120 --> 02:48.810 as well. 02:50.220 --> 02:52.110 Okay, so this is all nice. 02:52.110 --> 02:53.970 Now let's go ahead and try to connect with that. 02:53.970 --> 02:55.380 So for connection, we need a string. 02:55.380 --> 03:00.540 So we're going to go ahead and say process dot, envy dot, whatever we called it into. 03:02.000 --> 03:04.040 E and V files db url. 03:04.040 --> 03:05.300 So let's copy that. 03:05.510 --> 03:06.530 And there we go. 03:07.280 --> 03:12.350 Now, once this is all connected, hopefully then we are going to go ahead and simply provide some of 03:12.350 --> 03:14.750 the properties that we did in the past as well. 03:14.750 --> 03:16.100 So let's go ahead and do that. 03:16.310 --> 03:23.960 Not the user they use new URL parser, so use new URL parser. 03:25.070 --> 03:26.030 So there we go. 03:26.030 --> 03:27.800 And pass on this flag as true. 03:27.830 --> 03:30.080 Hopefully I didn't made any typos up here. 03:30.170 --> 03:32.450 Otherwise database will definitely tell me up here. 03:32.450 --> 03:34.790 And we need to use the unified topology as well. 03:34.790 --> 03:38.150 So we're going to say use unified. 03:38.150 --> 03:43.400 Now it doesn't suggest me their unified topology. 03:43.430 --> 03:44.210 There we go. 03:44.450 --> 03:46.910 And this needs to be turned on as true as well. 03:46.910 --> 03:47.470 There we go. 03:47.480 --> 03:48.500 Nice and easy. 03:49.440 --> 03:54.680 Okay, so it looks like this is all good and OC what happens if everything gets connected successfully? 03:54.680 --> 03:58.880 We go ahead and simply log this message that simply DB was connected. 03:59.240 --> 04:04.070 DB DB got connected. 04:04.790 --> 04:10.100 And again, let's go ahead and remove this part and what happens in the cache part in case you are not 04:10.100 --> 04:11.660 able to connect it properly. 04:11.660 --> 04:12.290 Let's go ahead. 04:12.290 --> 04:15.740 And in this case first, let's receive the error. 04:15.740 --> 04:21.380 And once the error is being received, then we're going to provide a couple of console logs, console 04:21.380 --> 04:30.980 log, the first one got a DB come on and DB connection issues. 04:31.430 --> 04:36.230 And after that we're going to just go ahead and log the errors, whatever the errors we got. 04:38.030 --> 04:39.470 Just like that. 04:39.800 --> 04:41.840 And we need to exit the process as well. 04:41.840 --> 04:44.420 So we're going to go ahead and remove this one. 04:45.440 --> 04:45.800 Yep. 04:45.800 --> 04:46.520 There we go. 04:46.790 --> 04:53.040 And after that, let's go ahead and say process dot exit gracefully. 04:53.060 --> 04:53.750 There we go. 04:54.110 --> 04:55.370 So this is it. 04:55.370 --> 04:58.520 In case I haven't made any type of which we are going to get see in a minute. 04:58.520 --> 05:00.800 So this is all what we need up here. 05:01.250 --> 05:01.520 Okay. 05:01.550 --> 05:02.080 Looks great. 05:02.090 --> 05:03.050 Looks fantastic. 05:03.080 --> 05:05.570 Now we need to go up here and in the index. 05:05.570 --> 05:09.590 You can actually go ahead and start your database as soon as your app starts. 05:09.590 --> 05:15.350 But I think in my case, I would I would actually prefer that to get started as soon as the index file 05:15.350 --> 05:15.860 actually runs. 05:15.860 --> 05:17.570 So let's go ahead and first bring this up. 05:17.570 --> 05:21.380 So let's go ahead and say I want to bring in connect. 05:21.380 --> 05:28.430 I can actually go ahead and try auto import, maybe connect with database. 05:28.430 --> 05:28.730 Yep. 05:28.730 --> 05:29.210 There we go. 05:29.210 --> 05:34.190 So it has auto imported this line up for me and before the server actually starts, I would like to 05:34.190 --> 05:36.610 go ahead and connect this one just like that. 05:36.620 --> 05:42.720 Would love to add a comment here that says Connect with database. 05:43.710 --> 05:46.430 Okay, so now this should be all good. 05:46.430 --> 05:52.280 All I need to do is I don't even need to restart it says DB got connected and server is running so hopefully 05:52.280 --> 05:54.170 things are all good and all fine. 05:54.290 --> 05:58.850 Now further down the road, we need to now check that whatever the method that we have created is all 05:58.850 --> 06:00.020 working fine or not. 06:00.020 --> 06:03.530 But I think breaking it down into a separate video actually makes sense. 06:03.530 --> 06:06.650 So let's go ahead and move on to the next video and check our sign up route.
