WEBVTT 00:03.960 --> 00:08.040 I'm going to keep this video short because we are going to talk about loggers now. 00:08.040 --> 00:10.130 So let's go ahead and talk about the loggers. 00:10.140 --> 00:11.800 The loggers are really important. 00:11.820 --> 00:15.750 Majority of the time, we can actually get away just by saying console.log. 00:15.750 --> 00:19.200 But sometimes we need a little bit more information on top of console.log. 00:19.200 --> 00:23.160 Maybe you want to write them into some files for other team to actually analyze that. 00:23.160 --> 00:27.720 And bugs can be a little bit tricky to solve just via the console log in a bigger application. 00:27.720 --> 00:29.700 If you're just getting started, it's okay. 00:29.790 --> 00:32.880 I already have created a video onto the production grade loggers. 00:32.880 --> 00:34.410 It's available on my YouTube channel. 00:34.410 --> 00:38.790 You can watch it by presentation as well, and there are a lot of places by which you can actually watch 00:38.790 --> 00:42.480 it or search it on just YouTube production grade loggers by my name. 00:42.660 --> 00:47.220 So what we're going to use, are we going to set up a production grade logger in this application, 00:47.220 --> 00:48.810 the next one that we're going to create? 00:48.840 --> 00:53.340 No, we are not going to set that one because it consumes a bit more time and we are going to put a 00:53.340 --> 00:55.320 tangent and we'll just walk onto that. 00:55.320 --> 00:58.260 But no, it's not like we are not going to use any kind of logger. 00:58.260 --> 01:03.060 I'll walk you through with one, which is one of my favorite ones for just getting started with application. 01:03.060 --> 01:04.710 It is known as Morgan. 01:04.710 --> 01:10.140 Now Morgan is definitely not a match of what I have discussed in this production grade logger that is 01:10.140 --> 01:13.830 definitely much more of capable of doing a lot of things. 01:13.830 --> 01:18.600 But as you can see in the weekly download, this is like really a lot popular up here and all you got 01:18.600 --> 01:24.030 to do is npm install a morgan and again, yes, it is named after the Dexter CDs in case you are about 01:24.030 --> 01:24.270 that. 01:24.270 --> 01:27.870 So Arthur likes to mention that and usage is really simple. 01:27.870 --> 01:29.580 All you got to do is just require this. 01:29.580 --> 01:33.540 MORGAN And then you can predefined that what kind of things you are looking for that. 01:33.540 --> 01:37.800 So let's just say this is the method that you have defined, which is having a request and response 01:37.800 --> 01:40.290 and somebody is hitting you onto a URL. 01:40.290 --> 01:41.850 Let's just say slash my form. 01:41.850 --> 01:46.650 You want to see that if somebody is hitting me, what kind of ID he is bringing in, what kind of request 01:46.650 --> 01:49.710 he's sending, get request or post request or whatever is coming in. 01:49.710 --> 01:54.360 So in that case, you can actually mention the format string that how you want to see the information, 01:54.360 --> 01:59.820 for example, colon method, URL, status and all that information that you want to check out. 01:59.850 --> 02:05.130 In fact, if you'll go a little bit at the bottom side, notice here they give you all the response 02:05.130 --> 02:06.180 that how you can take it. 02:06.180 --> 02:12.600 So if I scroll it a little bit, yes, I know that's a lot, but I need to scroll a bit more here and 02:12.810 --> 02:14.520 probably a little bit more. 02:15.800 --> 02:16.610 And. 02:17.540 --> 02:19.330 I know this is not, but here it is. 02:19.340 --> 02:25.640 So at the very end of it you can see that this is a complete example of how to use the tokens and everything. 02:25.640 --> 02:27.800 So notice here it says colon ID. 02:27.800 --> 02:31.490 So anything that is coming up as an ID in the URL, we are taking this one. 02:31.490 --> 02:33.560 Then it says the method get post. 02:33.560 --> 02:39.350 What is the URL that is hitting up or you can just replace it via bit with the tiny and it will just 02:39.350 --> 02:40.550 give you basic information. 02:40.550 --> 02:42.350 You can definitely customize that. 02:42.380 --> 02:45.350 As you can see in this whole example, it is really simple to set up the. 02:45.350 --> 02:50.900 Morgan We just require it at the top and then we go ahead and use it as a middleware notice here to 02:50.930 --> 02:53.750 use Morgan and just use the tiny and that's it. 02:53.750 --> 02:54.770 That's all you got to do. 02:54.770 --> 02:59.240 Again, all of your methods, all of your routes that you are defining or controllers that needs to 02:59.240 --> 03:00.080 come after that. 03:00.080 --> 03:03.170 So placing of your Morgan is really important. 03:03.170 --> 03:04.460 So make sure you do that. 03:04.460 --> 03:07.580 And again, this is basically of how the loggers actually work. 03:07.580 --> 03:11.810 And yes, I do agree that even if you don't install Morgan, you'll be absolutely fine. 03:11.810 --> 03:13.610 There is nothing that you'll be missing out. 03:13.610 --> 03:17.390 But I say that, hey, get in a habit of using some kind of loggers. 03:17.390 --> 03:21.950 Maybe Morgan is a great place to get started with, because when you'll be moving into a company which 03:21.950 --> 03:25.850 works on a bit of a scale, then you'll be seeing this production grade logger. 03:25.850 --> 03:28.250 And I don't want you to get freaked out that, Hey, what is this? 03:28.250 --> 03:29.180 I never studied it. 03:29.180 --> 03:30.380 I never understood it. 03:30.380 --> 03:33.170 No, these grader, these production grade loggers are pretty common. 03:33.170 --> 03:36.260 So, again, spend your time a little bit onto this video as well. 03:36.260 --> 03:41.510 It's a nice video, kind of a crash course on using production grade logger, or you can skip it to 03:41.510 --> 03:44.240 watch this Winston video at the very end of the course. 03:44.240 --> 03:47.900 So kind of a right to note that after finishing this course, I'll watch that. 03:47.990 --> 03:48.740 So that's it. 03:48.740 --> 03:50.930 Let's keep it short and move on to the next one.
