1 00:00:01,600 --> 00:00:04,270 The last video we saw, what do we mean by cookies? 2 00:00:04,660 --> 00:00:07,900 But in this video, we'll see what is a session for? 3 00:00:07,900 --> 00:00:12,070 Session is a period of time when a browser interacts with a server. 4 00:00:12,880 --> 00:00:18,730 So basically, when we log in to a web site, the session starts and a cookie gets created. 5 00:00:19,420 --> 00:00:26,550 So whenever we need to use a page that requires authentication, they always check against that acto 6 00:00:26,560 --> 00:00:32,530 cookie that is there on our browser session ends when we log or cookie that is related to the session 7 00:00:32,530 --> 00:00:33,340 gets destroyed. 8 00:00:33,790 --> 00:00:37,600 So basically when we open a website. 9 00:00:41,710 --> 00:00:42,870 They're the browser. 10 00:00:44,620 --> 00:00:49,000 Chicks caught up after cookie cutter active session. 11 00:00:51,220 --> 00:00:57,880 So, for example, if you are logging into your Facebook or some other social networking app, you need 12 00:00:57,880 --> 00:01:00,190 to log in using the password every time. 13 00:01:00,520 --> 00:01:05,170 So once you log in, it will be remembered, you know, remember me for some time, I remember me for 14 00:01:05,170 --> 00:01:09,520 a month, but they basically they're creating a session for that much amount of time. 15 00:01:09,970 --> 00:01:15,160 So when they're following your browser finds the accusation, it will not ask for the password of genetically 16 00:01:15,160 --> 00:01:15,550 logging. 17 00:01:16,030 --> 00:01:21,730 Only when you click log out, then that cookie gets related to that session gets destroyed. 18 00:01:22,150 --> 00:01:22,570 OK. 19 00:01:23,080 --> 00:01:24,130 This is what happens. 20 00:01:24,880 --> 00:01:27,100 So this is what session means. 21 00:01:27,730 --> 00:01:31,120 It is basically a time in the browser in Bratislava. 22 00:01:31,540 --> 00:01:36,340 And then based on this session, will create cookies that do cookies and destroy the cookies and everything. 23 00:01:36,820 --> 00:01:40,900 So hullabaloo that OK be have understood the theory of setting up like, you know, creating cookies 24 00:01:40,900 --> 00:01:47,530 and sessions and then destroying them and everything, but how to implement that in the code from then? 25 00:01:47,650 --> 00:01:49,690 That is where the passport comes in. 26 00:01:50,080 --> 00:01:51,160 We lose passports. 27 00:01:51,310 --> 00:01:55,630 It is basically a simple and unobtrusive authentication for Node.js. 28 00:01:56,500 --> 00:02:02,710 It up all sort of strategy supporting authentication like using username and password, using Google, 29 00:02:02,710 --> 00:02:05,670 using Facebook, using Twitter and more for passport. 30 00:02:05,830 --> 00:02:09,580 Jazz is something that everybody uses in its website. 31 00:02:10,240 --> 00:02:11,350 And what are the documentation? 32 00:02:11,360 --> 00:02:12,340 This is the website for it. 33 00:02:13,130 --> 00:02:17,140 It will have many things it will have Google logged and everything. 34 00:02:17,980 --> 00:02:24,370 So here, if you see it, it is a passport, Facebook passport, Twitter, Google or lot. 35 00:02:25,030 --> 00:02:31,180 And then it will have many things like GitHub and it will get a passport so you can log in and do everything 36 00:02:31,180 --> 00:02:35,710 the Google authentication part will see in the next related to final video. 37 00:02:35,980 --> 00:02:41,830 So before that, there is one thing that you have to know how to install this passport, jazz and everything. 38 00:02:42,550 --> 00:02:45,310 So for that, we'll see some quotes. 39 00:02:47,920 --> 00:02:50,770 The first thing we have to require all the packages. 40 00:02:51,200 --> 00:02:53,660 So what are all the packages that we have to request? 41 00:02:54,110 --> 00:02:55,790 So there will be an Bayamon start. 42 00:02:56,090 --> 00:03:00,110 It is the basic code and payment style for everything and what we have to construct. 43 00:03:00,860 --> 00:03:02,330 We have to install a passport. 44 00:03:02,870 --> 00:03:06,230 We have to install passport local. 45 00:03:07,370 --> 00:03:08,390 We have to install. 46 00:03:10,320 --> 00:03:12,330 Passport local. 47 00:03:13,780 --> 00:03:14,500 Mongoose. 48 00:03:15,280 --> 00:03:19,270 And then we have trained start express suspicion. 49 00:03:21,300 --> 00:03:21,720 So. 50 00:03:22,910 --> 00:03:29,450 Once we install them, you can require all the install packages if you've got to gorgeous. 51 00:03:29,960 --> 00:03:34,970 You can request all of them like passport, local mungo's passport session and everything. 52 00:03:35,540 --> 00:03:41,420 But one thing that is not required is passport local because it is one of the dependencies that will 53 00:03:41,420 --> 00:03:43,460 be needed by the passport local most. 54 00:03:43,970 --> 00:03:45,650 No need to record it explicitly. 55 00:03:45,980 --> 00:03:48,740 So this passport, this is a soft model of that. 56 00:03:49,130 --> 00:03:55,130 This is just a model of this passport local man was wanted to export, you know, required this separately 57 00:03:55,400 --> 00:03:56,120 explicitly. 58 00:03:56,930 --> 00:04:00,380 So after doing this, we have bought initialize the session. 59 00:04:01,190 --> 00:04:02,720 So how to initialize the session? 60 00:04:03,050 --> 00:04:10,700 This is also being of the session is I've got use session will send the secret resales false save and 61 00:04:11,570 --> 00:04:13,280 save on initializes. 62 00:04:13,970 --> 00:04:17,630 So this call we got from the documentation, you can check for the documentation here. 63 00:04:18,530 --> 00:04:23,390 Everything will be in clear format, but we'll see the code that is required for our. 64 00:04:24,800 --> 00:04:30,910 After doing this, this is basically initializing this app, not use passport, not initialize. 65 00:04:31,520 --> 00:04:32,300 So if you see this? 66 00:04:33,400 --> 00:04:35,730 Yeah, it is, I guess. 67 00:04:35,750 --> 00:04:35,920 Yeah. 68 00:04:37,440 --> 00:04:42,960 So if you see this court produce passport initialise, so I have initialized the passport and of initializing, 69 00:04:42,960 --> 00:04:50,790 we have to use the session after this passport session and then at Passport Local Man List, what one 70 00:04:50,940 --> 00:04:51,480 schema. 71 00:04:52,320 --> 00:04:57,210 So we'll basically add this plugin passport local English to the user schema. 72 00:04:58,230 --> 00:05:04,140 This is what we are going to use to hash in certain passwords and to save up use to database. 73 00:05:04,500 --> 00:05:06,420 OK, schema should be a mongoose chemo. 74 00:05:06,930 --> 00:05:11,670 So basically, if you are not using passport, even if you don't write, this one was keyboard, it 75 00:05:11,670 --> 00:05:12,120 will work. 76 00:05:12,690 --> 00:05:17,730 But since we are losing passport and then using passport plugins for that schema, here it should be 77 00:05:17,730 --> 00:05:18,630 a mongoose schema. 78 00:05:20,450 --> 00:05:24,410 So then using the passport local configuration, we can create strategies. 79 00:05:24,920 --> 00:05:28,760 So this strategies that can be, you know, I'll show you. 80 00:05:28,950 --> 00:05:29,560 Yeah, it can be. 81 00:05:29,570 --> 00:05:33,800 Global strategy can be a Facebook strategy on all this kind of stuff. 82 00:05:34,430 --> 00:05:38,450 So once we create the strategies, we'll see, it's creating strategies in the next Twitter that is 83 00:05:38,450 --> 00:05:39,680 Google authentication. 84 00:05:40,490 --> 00:05:45,740 Then serialize and DC delays are useful when we're creating sessions. 85 00:05:45,980 --> 00:05:48,800 So what is serialize serialize means? 86 00:05:49,960 --> 00:05:51,340 I will write it. 87 00:05:52,420 --> 00:05:54,400 So what do you mean by we? 88 00:05:55,950 --> 00:05:56,850 Legalized means. 89 00:05:58,440 --> 00:05:59,340 Create a cookie. 90 00:06:00,700 --> 00:06:02,320 And store information inside it. 91 00:06:04,010 --> 00:06:04,760 And store. 92 00:06:06,440 --> 00:06:10,430 Information inside it any more than we would be. 93 00:06:11,940 --> 00:06:12,660 Serialize. 94 00:06:14,070 --> 00:06:14,970 This basically. 95 00:06:16,200 --> 00:06:20,280 Crumble the cookie and retrieve the information, crumble the cookie. 96 00:06:22,550 --> 00:06:25,010 And retrieve the information. 97 00:06:26,500 --> 00:06:28,920 This is what I mean by these intelligence serialize. 98 00:06:29,770 --> 00:06:34,990 So if you've got any deprecation warnings, search them in Google to find the solutions. 99 00:06:35,620 --> 00:06:35,980 OK. 100 00:06:38,600 --> 00:06:44,710 So one thing we can do, right, but get pushed out score by checking the passport, local mungo's documentation 101 00:06:44,720 --> 00:06:46,010 and BMJ is dot com. 102 00:06:46,880 --> 00:06:47,240 OK. 103 00:06:47,510 --> 00:06:52,910 So for registering, we can check the documentation of Passport Local Mongoose for logging and log what 104 00:06:52,910 --> 00:06:56,390 you can check the documentation for passport just or documentation. 105 00:06:57,080 --> 00:06:57,440 OK. 106 00:06:59,560 --> 00:07:02,680 So one word of advice quickly gets deleted with no relation to seven. 107 00:07:05,090 --> 00:07:11,060 So if you see this here, this is initializing everything, and then we are using the schema and then 108 00:07:11,060 --> 00:07:16,600 we using created start again, then serialized user DC realizes he's a realizes it is a disease, as 109 00:07:16,640 --> 00:07:19,100 you know, I want to give it to resources. 110 00:07:19,850 --> 00:07:27,330 So here you can search for the log in and logout caught in this documentation and in that vein being 111 00:07:27,350 --> 00:07:28,010 passport. 112 00:07:32,950 --> 00:07:38,510 And that in the pocket baggage password passport, you can search for the register like you can see 113 00:07:38,510 --> 00:07:40,210 serialized user serialized user. 114 00:07:41,270 --> 00:07:45,950 And then logging strategies, and they will be done in this tool documentation, you can go to it. 115 00:07:46,340 --> 00:07:50,900 But the basic idea is we have to understand what you are doing like what new passport means, what is 116 00:07:50,900 --> 00:07:54,170 cookies, what is sessions and what do you mean by serialize? 117 00:07:54,170 --> 00:07:55,580 And do you see that as an all those things? 118 00:07:56,600 --> 00:08:02,850 So with this, we are completing the cookies and sessions now, the final part of our web pages, Google 119 00:08:02,900 --> 00:08:10,340 authentication, how to use the Google servers to store the passports in their database and then access 120 00:08:10,790 --> 00:08:15,740 give the user a choice of logging in with his Google or Facebook account. 121 00:08:16,340 --> 00:08:19,260 It is basically all 2.0 will see that in the next. 122 00:08:20,060 --> 00:08:21,240 That's it for this video. 123 00:08:21,260 --> 00:08:21,650 Thank.
