How Email Verification Works – Step-by-Step Logic

Hello what's up guys, today in this we will see schema for email verification, yes guys, today's video is very important, believe me, because here you can see that in this particular project we have completed the email verification, however, this process, we are going to see one by one in the upcoming videos, which is going to be very important, but one thing I would like to tell you today in this video that today's video is very important because I am going to tell you the complete logic that what is the reason behind the email verification that we are going to do, okay, so look carefully, first we will cover the theory, then there will be a small code which we will see in this video today and then we will see it piece by piece step by step, day by day, so guys, now look carefully, currently this is a home page right and here we have our simple database which we are doing in diesel and this is our QRL short project, if I go to my profile page, then you can see Maybe that links createddocumentsfragment verification here you can see verified right but I have already verified that email I have received we have seen a lot so now I will tell you that if it is not verified then what is the secret behind it and how will we deal with it look carefully I will go to my database so here we have a database named user basically there is a table user where there is id there is name email there is password and there is an important field and that is email is valid till now we have not created it but today in this video we are going to create this only this is the schema for your email verification now now we have to add a schema inside our user here you can see two out of false one of the value is true this one which is true is currently this and that is now when I come back to the profile and boom guys see this is it this is what I want to show you now see the real logic of not verified and verify now Have a button, now what is the logic, I will tell you when you click on verify now, you will come to a page, the name of the page is verify email, listen carefully, inside that you can see that here we have given a button recent verification link, when the user clicks on it, we will get a link, we have to click on that link, there will be token and then the verify link part will be right and then our verification will be done, but I tell you, let's see and see now, okay, when I click on this, I am going here and boom guys, see what is visible, you have got a link verify email here, okay we are using there, first we will use there as AMTP server inside nut mailer, after that we will tell you in another way, the mail which will also come on your official g mail, we will see all that, but right now it is important for us to understand the basics, where I have got a link control and then I will click in this way, so I would like to open it, so it opens in the moment So you get an interface like this where you can see click the link below to verify your email in which you can use this token or you can click on this particular anchor tag for basic link so we will have two ways to verify the email, one you copy a token of eight digits or you can click on this, okay I will copy it here, here the CSS is a little messed up, don't worry I will tackle it and when I click on the verify code, okay what will happen, look I click and boom guys look it has been verified, right it has been verified now if I go here which was false now I will refresh it yes and how to refresh, you can see the result here so I refresh it so look this has become true it means that if the value here is true then it gets verified and we do not have to do anything manually, everything is happening dynamic now I will go back here to this I fall back, I would like to come back to save changes and I go back to home and come back to profile, we can see this Verify Now, so one thing is confirmed that there is a table, I mean there is a field in our user table which is very important and this is yours, I mean and that is is your email valid and this is the field that we need to create in this video today because it is completely dependent on it whether we want to display the verified icon or not, understand why today's video is important and every video will now be important every day, you understand every video will be important every day if you are understanding it carefully, now again I fell back because I just showed that when I copied and pasted that token, then it got verified, what if I just click on that link, okay then I will go back to Verify Now, remember this much, when I clicked on Verify Now, I did not get any email I haven't received any mail or it happens many times that when we register then we get an email to basically verify it, I mean it comes on our G mail, do you understand what I am saying, whenever you register in general then the link to verify is sent to your mail, then they say brother verify the email, we will see that later, don't take tension but for now if you understand how the process is happening, life will become very easy, until I don't click on it, that link is not generated for me and we are using it physically and that guy is for testing purpose, that's why it is visible to us on our console and that 's why I am opening the console and clicking on that link but we will see everything later, I will see again carefully this is part here, okay now if I click ok clicked, I will get a mail in a while and I have got a mail, I will click on open again, so a while ago I showed you how I copied the token and then I clicked on it there I went and verified but what if I click on this and look carefully here is this what can I say Raj Raj will be here and that is alright see over here okay look at this this part which is visible guys this part is very important here because here we are passing the token also here we are passing the mail also and this is the same route which I am calling when I was clicking on that button by entering the eight digit token the button on which I was clicking to verify, we were calling this very route so all these are connected with each other I know right now you are able to match a little bit but the reality is you have to click on that button and clicking here is very easy because there I was manually entering that eight digit character and here if you and perfect this is it look what token is visible you are seeing the token here so I was entering it manually there here I am passing it on the URL itself and requesting query I will get the data through it, just simple, if I click on it, boom guys I am verified, so these are the two ways through which we are going to track our email verification process, but this is just a trailer, next we will see how we can get an actual amazon.it token, then verify link, all these things in your actual, we will also see that log in with googleupdate.exe mode or you can say hybrid authentication since we have started, okay, I would like to tell and that is refreshing form validation, okay, from this place you can say kind of session and JWT authentication from here, this part, you will not find it on my channel till date, so this latest, whatever I am creating here, you cannot miss even one of these, there would be very few channels who would have created this and posted it for free, okay and that's why guys I am getting so much into theory these days Because if you want to be a better developer, then you must know the whole process. Then you should code, at least you should know the whole process. What is the process of this website? Not at least when you are creating an email, you should already have an idea of ​​the logic behind it. Then you can code. It is not that you will keep coding and the logic will come and it will work for someone. But it is very rare. That is fine. But I hope you must have understood. And one thing that you must have understood very well is that this particular part is email validation and verification. There is also email token. Look here, user ID token and expire item. So this part is very important which we will see in tomorrow's video that now we have to create this schema as well. And this schema is used to verify email. And this schema that we are creating, this schema we are creating to make this particular field. We have to add an extra field. That's it. So I hope you understood the whole logic. What are we going to see next and believe me this is just this much, when you will see it next, we are going to do it even better, okay but I want you to sit comfortably and watch it every day, if you want, you can investigate yourself that how can I make it even better, I can use something else instead of etherel, there is a lot, okay so guys, now we start the video without any delay, but if you liked this theory part of mine and you got to know what we are going to see in the coming few days, then please like the video and share it with friends, if you have any doubt, then definitely comment, if you do not ask, then I will not be able to tell you and I generally want you to ask such a doubt that I also feel wow friend, now force me to think, oh I did not even think about this, you are not understanding and please subscribe because without subscribing, then guys tell me where to get that motivation because every single thing that I am making, someone has also put it in my mind for free I might not have put it in, brother, I also have to work hard, behind this there is my team which is creating content for us by working hard, so there is so much, so guys, if you think even this much for us, it will be a very good thing for us, so please subscribe, I will be very happy and you should not have any problem in the source code, so guys, for that we already have the source code for you absolutely free, I have kept it for you, so no tension, you must check it out, here you will get it of get hub, how can you access, everything is there and if you want to genuinely support, then guys, you can get my entire youtube1 and all these things from here, only and only 199, you can check out by clicking here, okay, so now we start the video without any delay, so look, today 's video is very easy, so watch guys, first of all we go to our page, the page with schema, okay, so first of all it is very important to go to the schema page because today we have to add a field to our users table So this is our user table, you can see it very clearly, oh here one second one second yes guys you can see or this is it, look at this and this is a user table and users there we have kept the name of the user empty, there is everything here, just one k and that is email is valid, okay so I will create it now, let's go under email or password, is email valid, okay and okay so what is this guys, you see, it is either true or false, so this is an integer, isn't it, this is your variable character, this is a boolean value, which value is it, it is a boolean value, okay dot now here one thing you have to notice whenever someone is logging in for the first time, okay okay, whenever someone is logging in for the first time, remember this much, the value of this, if you must have seen a while ago, then guys it was false, false, false, okay so what we have to do, it will have a default value which I would like to set and that is false and it should never be null, so not I am making it null. Now this name is email valid. So here it is not like this, it is under email underscore valid. So one thing is that guys, what are we going to create in this way and if I show you beforehand then your life becomes so easy, right? That means, okay friend, I have already seen this table. I mean, I have done this. We are going to do this. Now if we run it, then I will not get this table. Basically, I will not get this field. So, it will be easy for you guys. What are we going to do? That is why I try my best to show you everything beforehand, right? Alright, so is email valid. Now remember this much, it is very important when you are working in Diesel and that is, when you change anything in the schema, you know we need to generate and then we need to migrate so that it gets reflected in our database. And its sequel becomes corresponding. Alright, corresponding sequel. The code should be my sequel, so make sure that this balloon control and then space should be implemented on top, I mean it should be imported, so we have a balloon value. Now there is not much change in it, it is just that we have added an extra feed to our user table. I would like to run here. Now first of all, before doing this, run npm one second. Ok, ok, npm run db underscore we need to generate. Ok, I am hitting enter. Ok, so you can see that they have made some changes in the users table. So you can see that they have added one thing. Ok, add this gmail valid balloon default false not null. So, this has now been added to our table, but now we also have to reflect it, we will have to migrate it. So, npm run db underscore migrate. When you do this, then it is actually reflected there. See, the session table already exists, but You don't have to take tension here now I would like to go to this place npm run db and then studio so when you run this command then you see this so here you are seeing it I will refresh it once let's check it out what happens so this is a user and we have this much field over here so guys right now you can see that we are not able to see it but it's fine but whatever it is we will tackle it but we have done our work from our end okay now this that you have created now where all do you need it I will tell you to see from the bottom so first of all now come to our profile page okay if you remember that what I am showing you a while back basically this will not work now your this is okay okay it is still working very good okay so this particular code that you are seeing I want it now where I had shown you if it was not verified then what would it look like if it was verified then it would look something like this So I need this code and it is dependent on what, I will tell you to look carefully, so this is a profile where if you see, basically the links created profile button is fine and it is the last active in between them, so I have to write that code here, now guys I already have that code and it's not that big, so I do n't want to waste your time, I will paste it, there is nothing, it's a very simple logic and that is here, first of all you will see the email verification, you will see the email verification and then here after that the value is changing and it is dependent on what is your email valid, so whatever is inside the user's table through the user, okay, this is inside our token, basically the user is our token right now, so here you can see that the user does email is valid, so it means that we are passing through our controller this one field and on the basis of that field we are deciding I mean If its value is true then show verified which is showing right now if it is false look else not verified has been used remember we had shown earlier not verified is shown in red color and then you will see a button basically an anchor tag is visible which says verify now and when I was clicking on it then I was getting a link basically not link we were getting redirected to a page and inside that page I was seeing the resend button then so in this way that's all the code and this code that we have written is written in our ejs ejs and we are working on that our template engine is okay I will save the control and now one thing here is that inside this user this email I mean email is valid property where did it come from there is no tension I would like to go to auth data controller look here carefully this is get profile page okay and inside au there is profile that means whenever someone clicks on this route Basically, I will show you that whenever someone goes to the profile page, we are opening this get profile page controller, there I found out the entire user data through find user by id and I also needed the short links table, so I found that out as well. Now this user has all the tables of the user, we are getting their data very easily, basically, the entire data of whichever id matched, by complete data, I mean this entire suppose which was the first id, so I am getting this 11 id number 11 Vinod Bahadur Thapar test, this entire data is coming to me, but recently I also created it by making is email valid, so it means that I will go here, email not email, whatever it is, is email valid, I will copy it and paste it here and here user dot is email valid, I will pass it in this way, this is it, so in this way we have passed it here and here I am now using it in this way, I hope you have understood till here, okay now. One more thing is important here, now I am removing it. I am removing it. So I have used email valid at two places. We have to use it at other places as well. Like, I would like to use it on the auto controller. Whenever we are creating an access token, I would like to pass its value there as well. Why am I doing that? We will see that later. But for now, just pay attention. When we are playing with the access token, see the video of the authenticate user dry principal. If you remember, I have recently added the dry one, which you can see by the way or over here. See, two days ago, in this video of implement drive principal, I showed how we have created a function. And I have come inside that function. Now, if you see, this particular code, I would like to add one more thing here. And that is by default is email valid. This property is what I am adding. And here, by default, I am keeping its value false. By default, I have kept its value false here. Okay, I copied this here, I kept it here, I need it, we can check out through access token also, and one more place is very important, th dot a, this is basically verifying, here we are talking about this, look at this one here also, so if your access token expires, then we can refresh both of them with the help of refresh token, that's why I told you that you will just watch the video, oh I understood, and after a week the whole mess comes out, I don't know what happened here, so this will not work, okay, so we have this access token verify access token, we have this refresh token, so here you look carefully, when I am talking about refresh token, so refresh token here, look at this, if I go on this, then here this user's info is like this, so what will I do in this user info, I will paste this code, now here we can do one thing, here this user, if you look carefully, what am I doing? I am finding from my database, so if I talk about my database, then I am getting all the data of everyone through my database, so what can I do then, here instead of false, I will say that whatever value your email is valid, whether it is false or true, you can add it here, that is very important, on one hand I am doing it manually at this place and I did it manually at this place because from where was the data coming to me here, the user was not getting the data, but yes, here I get the data because when the access token is not expired, it means once we have provided the access token to him, we have to understand a little bit here, okay, I am passing it for my profile page and on the profile page I am checking out that if the value of gmail valid is true then it is verified, if it is not, then not verified and the verify email button has to be shown, it is used at four places and I did it in the schema Create So ya guy this is it That's all for this video today Let me know in the comment section Guy how did you like today's video and then did you understand the main logic or not In tomorrow's video now we will create the actual schema for verifying our email I have already shown you what all is required for that but tomorrow we will understand it in depth but I hope guys you liked today's video and you must have understood the complete logic and regarding whether your field of email is valid has been created or not Let me know in the comment section If it has not been created then we will tackle it tomorrow you don't have to worry but whatever I had to tell you in today's video I have shared with you I hope you liked the video very much So guys if you liked the video then please like and share it with friends our next target is 8 lakh subscribers If you haven't subscribed yet then please do I will meet you in tomorrow's video till then guys Thank you so much take care [music]
