WEBVTT 00:03.880 --> 00:09.360 Hey that everyone that they sure and welcome to another section of this pro back end of course. 00:09.400 --> 00:13.840 Now, before we move ahead into this section, it is very important to understand that where we have 00:13.840 --> 00:18.940 reached so far, so that you can understand the beauty of the structure of this course, definitely 00:18.940 --> 00:19.540 that is one thing. 00:19.540 --> 00:24.070 But it will also help us to understand that where we have reached so far and what we have to do now. 00:24.100 --> 00:28.840 Game Plan Action Plan is one of the most important things while learning, and that's where I will help 00:28.840 --> 00:29.240 you. 00:29.260 --> 00:34.450 So let's talk about the entirety of the things so far what we have learned, what we have done, what 00:34.450 --> 00:37.180 we need to do further, and how we are going to proceed. 00:37.270 --> 00:41.170 So, so far, now we know that how we can move things on to Heroku. 00:41.200 --> 00:41.920 We have seen that. 00:41.920 --> 00:46.980 How much important is the port variable and how much important of the line the process is? 00:47.060 --> 00:50.710 And that we haven't talked much about it because there was no need of it so far. 00:50.710 --> 00:53.050 But now obviously it is going to be in need of it. 00:53.110 --> 00:57.490 So from the very first section, we are taking care that how things move into the production, we need 00:57.490 --> 00:59.860 to take care of that and we will be doing that. 00:59.860 --> 01:06.100 But nonetheless, we still know that how we can push things onto Heroku and we will now move on in a 01:06.100 --> 01:08.410 similar direction that we have to push it on there. 01:08.410 --> 01:10.720 So we need to use all those information. 01:11.020 --> 01:14.910 Apart from this, we also know a whole lot about the request and response. 01:14.920 --> 01:19.780 We have dedicated the entire section of the swagger, and the reason why that section comes first is 01:19.780 --> 01:24.550 so that you can understand more about the request and the response, and you get enough time to study 01:24.550 --> 01:26.860 more about the documentation of EXPRESS. 01:26.860 --> 01:32.830 And now we are at this position that if the data comes up from the URL, from the query, from the body, 01:32.830 --> 01:36.340 or maybe the images, you can handle all of them into your backend. 01:36.340 --> 01:41.320 Not only that, you also now understand that how you will be sending some response, whether it's a 01:41.320 --> 01:45.700 regular response as a string format or maybe a JSON response or a status code. 01:45.700 --> 01:47.050 So you know all about this. 01:47.050 --> 01:52.510 This is so much of a good progress, but we have seen that we fall into some of the problems. 01:52.510 --> 01:55.760 In case you noticed in the last video, we were writing everything into the app. 01:56.020 --> 02:02.080 JS So we need to understand a couple of things that files are getting really big and file, which needs 02:02.080 --> 02:05.560 too much of the scrolling are really not the best thing. 02:05.830 --> 02:09.040 Surely in some cases we need to keep things organized as well. 02:09.070 --> 02:13.510 It's not really about getting the file too big, but it's more about the organization and you might 02:13.510 --> 02:15.310 be asking why we need that organization. 02:15.310 --> 02:16.870 This is already working great. 02:16.870 --> 02:18.130 Yes, that's a good point. 02:18.130 --> 02:21.550 But we are going to be working into a multi development environment. 02:21.550 --> 02:24.910 There will be multiple development developers involved in the project. 02:24.910 --> 02:30.430 Some will be handling controllers, some will be handling routes, some will be writing maybe middleware 02:30.430 --> 02:31.210 and all that thing. 02:31.210 --> 02:32.860 So we need to take care of that part. 02:32.860 --> 02:35.410 So we will be working on that now. 02:35.410 --> 02:37.180 We will be doing this a step by step. 02:37.180 --> 02:41.740 It's not like you are going to learn the entirety of how to rip apart a project into multiple separate 02:41.740 --> 02:42.940 file in just this section. 02:42.940 --> 02:43.930 Eventually we'll do it. 02:43.930 --> 02:48.340 We'll do some part in this section and the later on will come up into the next section. 02:48.610 --> 02:50.260 Nothing is permanent so far. 02:50.260 --> 02:53.110 This is also another of the problem that we have seen so far. 02:53.110 --> 02:54.100 We created an array. 02:54.100 --> 02:58.960 We were pushing into the array, but as soon as the server restarts, it just poof, everything is gone. 02:58.960 --> 03:02.740 So this brings the need that we need to now inject a database. 03:03.370 --> 03:04.300 Now what database? 03:04.300 --> 03:08.920 You'll be choosing, what Aurum will be, we'll be choosing and what even Aurum is. 03:08.920 --> 03:14.050 We need to take care of all these things, but one thing is absolutely sure that we need some kind of 03:14.050 --> 03:16.540 database and we need to study a little bit about it. 03:16.570 --> 03:21.790 So how we choose the database, how we make a study of the database, again, that comes up just almost 03:21.790 --> 03:22.570 like EXPRESS. 03:22.570 --> 03:24.190 But I will walk you through with that. 03:24.280 --> 03:29.050 Now, one thing we need to absolutely make sure that happens in our back end is we need to hide our 03:29.080 --> 03:29.800 secret. 03:29.830 --> 03:34.690 Now, eventually are going to notice that that process, that EMV, we saw that in the Heroku, that 03:34.690 --> 03:38.310 it's a very secretive file and it has a key value pairs. 03:38.320 --> 03:41.860 That means some variables need to be declared and some value needs to be declared. 03:41.890 --> 03:44.770 Your entirety of the back end is run through those secrets. 03:44.770 --> 03:50.890 Those secret can be a direct link to your database URL, maybe some of the secrets that will help you 03:50.890 --> 03:52.450 to generate some algorithms. 03:52.450 --> 03:59.080 And by the time algorithms I mean to say edge mac algorithm or maybe SHA 52 or maybe SHA 256 not SHA 03:59.080 --> 04:02.320 to 250, SHA two 5256. 04:02.320 --> 04:07.660 So we'll be having a whole lot of such algorithms that are governed by the secret or some seed values. 04:07.660 --> 04:12.220 And these are some secrets that we need to protect and for that we'll be studying all of that. 04:12.220 --> 04:15.520 So just to give you a quick summary, we need to learn how to inject the database. 04:15.520 --> 04:19.450 We need to make sure that files are being separated out into multiple components. 04:19.450 --> 04:22.120 And we also need to take care how we can hide the secret. 04:22.120 --> 04:26.290 So there is a lot more that we have to go through now and there is a lot that we have already learned. 04:26.290 --> 04:28.450 So now you have the idea. 04:28.480 --> 04:29.680 Now just one last thing. 04:29.680 --> 04:34.480 There is also one issue that we need to address and we obviously will be addressing in this particular 04:34.480 --> 04:35.770 section right now. 04:35.770 --> 04:39.250 All of our routes are open, get post or whatever that out are creating. 04:39.250 --> 04:41.380 Those all routes are open. 04:41.380 --> 04:44.860 Anybody can access those routes and can just put any value into that. 04:44.860 --> 04:49.840 We need to learn how we can authenticate those routes, maybe by username and password, or maybe there 04:49.840 --> 04:54.220 are a couple of other ways as well, but we need to learn that now and that's exactly what we'll be 04:54.220 --> 04:55.480 doing in this section. 04:55.480 --> 04:59.920 So I hope this gives you a clear idea of what we have done so far and what we are going to do in the 04:59.920 --> 05:00.850 next section. 05:00.850 --> 05:01.750 Let's go ahead. 05:01.890 --> 05:03.390 And walk into the next one.
