Send Emails in Node.js Using Nodemailer & Ethereal – Step-by-Step

Hello what's up guys, today in this video we will see how to send email using nad mailer, yes guys, today's video is very important because we were waiting for it impatiently, finally today that moment has come where whenever someone clicks on the recent verification link, then guys a mail comes on our console, when I click on that, then guys you see an interface of this type, today we are going to see all this in this video, you don't worry, but finally till now if you are watching me, then guys congratulations because you have a lot of patience because I feel that for almost 3 months I am continuing this series and these 3 months if you follow me then it is a big thing and finally now day by day one better than the other things are going to come which till today I must have uploaded 000 on my youtube, very less means hardly any 10 creators must have uploaded that video which I am going to do now, okay so now how can we do this our fully Flagged is a project in which finally now we are adding token basically we are looking at the email verification part okay so we have done till here we have done this while verifying our email if you remember what kind of link should be there we have done all that now we have to show this dashboard so first of all guys how can we send mail in our node application by saying so we have a node mail and I guess you will get it here also if I show you okay so this is you can see node mailer is a node.js library used to send emails node mailer is a library with the help of which you can send email we use therian email a fake email service for testing we will use theril only in this particular video but in upcoming videos we will use the recent and other things also through which your official the node mail and then in production you can use services like amazon2 and then we will use further Do n't worry, at least you got to know what is node mailer, it is a node's library with the help of which you can share mail and in that we use guys SMTP server, it can be any server but right now we will use Therian which is a fake email service provider, okay and mostly we do it for testing, so I'm going to go ahead, okay, here is your node mail, alright, you can see here, what is it, how is it, you will find everything here, what are the features of node mailer, everything is here, so guys, if you want to understand node mailer in very simple language, then you can understand that node mailer is equal to a post office where you go and pass your letter, but when you are passing the letter, as it is, you will not give it, guys in that letter there will be your content, you will write the full address of the recipient, to whom you have to send the last address and then whatever post office it is, guys, it's their job That delivery is basically to deliver it to the recipient's address. So, node mailer also does the same thing here, where there are just one or two methods which are important which you have to keep in mind. First is we need to create a transporter here and then second is inside that transporter, we get a method named send mail. So look carefully, once you understand this, your life will become very easy. Look, we required node mailer, it was not a big deal, we are creating a transport here. So, here the simple meaning of transporter is that guys, which SMTP server we are using, whatever data is there, we have to pass it here. It means its job will be to deliver our letter or our email to the place where we want to deliver it. Now, here this transporter, you can see which is smtp2go. Here, which SMTP server are we using or which service. We are using the real service let's say if I go to google2 goole.com the first thing we need to do is to create a transporter and its job will be to deliver our mail to the place where we want it to be delivered simple now once there is another method inside the transporter which I told you that is your send mail this is very easy whenever you go to email you know open gmail if you want to send mail to someone then what do you do first of all you mention to whom you want to send it then you write the subject and then you write your content whether it is in text format or atml format if you write any one of the two then we will write one and pass it and yes by default we do not need to write a form there because we are already logged in there we are logging in with our own id right if we click on send then our mail will go to them but here we do not have anything like that so first of all we write the form also see how much It is easy, just which service are you using to send mail, there is a method of send mail in which we have to enter the full address of the recipient and we have an address of who is the person who has sent it to you and that's it, that's all, create transport and that's whatever your object will be, dot send mail and that's it, so you do one thing, let's go to the real email, we go here and there is nothing to do here, you just have to click on it, the moment you click, guys a simple thing will come in front of you, you will get your user name and then password, okay, don't delete it, keep it as it is, now do one thing, first of all come here, ok, guys, you can see that we have come to our BS code editor, so first of all what we need to do, first of all we need to install node mailer, okay, so first of all we install it, ok, mine has been installed, now I am running it, now what do we have to pass to node mailer, guys This is node mailer, you can see we need to pass this particular data, which is inside send mail, who do I mean to whom do I have to send it, what should be the subject, what should be its content, we have to pass that, so I will create a function for this now and this function which I am talking about, so basically I have to create this code now because I am going to forward them in this format, right, so let me do one thing, send email will be the name of our function in which I have to pass the data, basically now I am passing the argument here, to whom do I have to send it, I have to send it to whichever user has logged in, okay, you created your application with lets and you hosted it live, now if any user from Madhya Pradesh is logging in, then this will be mailed to him, what will be the request url subject, let me do one thing, I already have it, this subject will be verify your email ATML, see the content will be either in text format or in your ATML format, but we are doing it in ATML format because Because we are going to need some links, some extra JavaScript part is going to be needed, so that is the reason why I am using template literals here and click the link below to verify your email. Click the link below to verify your email. Oh my God, finally, since then you must be thinking, how did this come here? How did this come here? From where is this token coming to us? So it is coming from here. You can use this token. You can use this token. And then the token that I am getting here is a random token because I have already generated a random token in yesterday's video and I have also added it to the table of my database. I have also created a link of my own. So this is just that message, which is the mail, which I have to forward. So this is just that. And even after clicking on verify email, it was getting verified automatically. The reason behind that is that I am redirecting it. Verify email link. Verify email link. Calling this means that I am going back. I am calling the create verify email link where this URL of mine is very important inside this verify email token route I have the complete functionality that this is the same email whose token we are checking or not simple okay so I go here my work is done and by the way many of you may have noticed or not but we have also used dot catch here now you are thinking where did the catch come from without try so I would like to tell you that this catch method is not only try catch if you have ever played promise then see in your promise also dot then dot catch dot then dot then dot catch is there right so here there was no neat dot then I wrote dot catch so it's your promise simple you can understand like this and if everything is correct then the response will redirect them to the verify email page from where it came back okay so This is done for you, now this send mail is obviously I have to pass it to node mailer, so now look, I need node mailer here, it is very important, look carefully, so let's do one thing, node mailer is a library with the help of which you can send mail, inside it we can use different services, whose job is basically to forward our mail, so it is a library, so I am creating a folder called LIB, inside it I will add node mail, okay and I would like to tell you one thing that this part is already given by them, so I will copy it, okay and I have already explained it, it is not a big deal, so it is very easy, now I don't need this common js module, I will import a node mail, okay, from node mail, okay, till here my work is done and yes one thing is for sure that now what do we do, here I am creating a custom account, do not take tension, create a test account inside it. We get it, okay, let's create a test account because we are testing and that's it, one of your tasks is done, then we keep one thing in mind here, you have to write await here, okay, now look, I did n't know that I have to write await here, when I was practicing this, I got an error, then I came to know that I have to write await here because the promise is returning, so there are some things guys, which you have to keep in mind that yes, it can happen here, it is not necessary that you always know everything, now this await happens here, we cannot do anything and there is no await here, then for some reason, but whatever it is, so this is how we are creating a transport, so create a transport, which service are you using, I mean SMTP, I mean real, I am using, its port is this, I have kept secure false, yes obviously I have to make it false because if it is true, then guys, we will not be able to work, the mail will not go properly, then this in auth Basically you change it and paste it here, this is Rosario, what is this name brother, Rosario or Rose Riya, is it like this and this is your password and for some and god sake and guys I request you guys to make your own and don't just sit down to copy paste it, okay, right, my transport photo is ready with me, it's like your postman is ready with you, everything is ready, you just have to take your letter and put it there, so now it is here, okay, I will do one thing, I am copying this, all that you can see here, let me delete it from my end and by the way guys I have deleted everything from there, okay now I will copy my own from here because I have already done everything, look, so this is my send email, we are talking about it here in which there is two subject and then HTML, two subject and then ATML now the most important thing here is what is its format, look carefully Now guys, finally the time has come where we have to send the mail. Now to send the mail, we know very easily that is transporter, so transporter dot we have send mail method and within this, you can share whatever method you want like what will you write under to, we have a second under to, so you already have to have the to, right, that means to whom do you want to send the subject, you already have the subject, I already have the subject, ATML is already with you. Now there is still something missing here, like if let's imagine, okay let's imagine, you have caught it online here, there was a verification button, you clicked on this, okay and you are there, where are you in MP, Madhya Pradesh, okay and here is your system, okay this is your guys system, now here let's say you got the mail, okay you clicked on this and you got the mail, but tell me one thing, how will you know who sent the mail. So let's say this is your email id, we know the subject, we also know the format of ATML, but who sent it from, where is it, when anything comes to your inbox here, in this way, first, second, third, then brother, we get mail, then how will we know who sent it, so where is we need one more, feed here that is your from, okay, do you understand, I told you this much because just this will not work, the from field is very important here and finally, from where will I get the data of from, I will get it from here, test account do user, fine, now you must have come to know that we have written this user and password here in authenticate because this is a particular method, in this test account, with the help of that, I can access all the fields inside auth, so I pass the value of from here in this way, so by setting the URL, whatever will be the value of this test account dot user, will come there, you will get to know from, okay, he has sent it, do you understand and I wrote this so that whatever email I have They come in the middle of this particular angle bracket and this URL is talking about a short project, so from to subject and now you let's say the transporter has shared the mail, how will you know whether the mail was shared or not, so guys, it must have given some response like every time, so whatever response it would have given, we need to wait, okay, the promise is returning by doing cost info, there is a stent variable on it, I would like to store it or this is it, okay, my work is done, now guys, what is happening here, is that we are not sending this to anyone's personal inbox and we need that link, so to get that link, we have another method, here inside the node mailer, a get test message URL, this is the beauty of it is providing you everything, it is saying, okay, you have to do testing, create a test account, you create a transport, you can use whatever you want to use, then what mail do you want to send, set your format The transporter will send the mail and after that copy this info and pass it here, meaning whatever you would have written and passed by whichever transporter would have passed it, whatever response would have come from that info object, you have to pass that here. Okay, so whenever you pass this info object, it gives you a URL, do you understand that, that means yes brother this is the URL in which I have passed it and that is the same URL which we are getting on it, so I have kept it as const test email URL, all right, let me do one thing, now I will copy and paste it and I just realize that you have to keep these two parts inside the send mail only, otherwise this info is a constant variable and its scope remains only within the braces, if I take it out, then I would never have been able to access this info, there are a few things which you have to understand, okay, and you do not remember everything the first time you see it, I hope you must have understood the funda, this is it my work is completed, no tension No, I will press control and save. The time for the exam has come. Let's check it out. So first of all, let's see if we have got this part or not. Okay, now I am going here. Okay guys, so if I refresh it once, this page will appear. I would also like to start my drizzle here. So guys, you can see that we have logged in. I would like to go to the profile. See, there is nothing till now. Today, let's pray that it is okay. So as soon as we click on Verify Now, we are going to a page. Till here, it is fine. This was explained in yesterday's video. Whenever we click on this, check it again. Let me explain it to you once again. What happens is that we generate a random token. Then we are storing it in our database using I mean including user ID. Then we create a link. And then what do we do? We are passing the send mail. Okay, what are we doing to the send mail? We are passing it and then we have shown the send mail in node miller in this way in today's video, we have set it up completely in this way, let's save the control and okay, I would like to open the console here now the moment, I click on it, lt is not defined, okay, no problem, this is the error of yesterday's video, I know where less than if you remember I said when you were working here, this less than part is jil oram, okay, okay I will go back, this is the refresh Ian's watch, guys, this is okay, I will go here, click, okay, oh my god, it is tormenting me in this way, right, I have done this as well, let's go back, I will click here, let's do one thing here just once, let's check it out, our easymail is valid, has any data come here or not, no data has come here, this is what it means So guys, something or the other has happened at this place, so we can do one thing, this is my part, whatever is my part, let's go with try and then catch, okay, if anything remains then we can catch it, let's paste the error here, let's check it out, okay, according to me, something is happening right here because this error that we are getting, God knows what kind of error it is, although we can check it out, it was not a big deal, oh my God guys, we got a mail, look here, look, I have received a mail, if I click on this, okay, there is something wrong, look, object promise verify email, if I am going to verify email, okay, guys, one interesting thing we are getting this here and that is that there is something wrong with the object promise token, but yes the email is equal, there is no problem in the email, so guys, let's do one thing, see at least this much we got to know, just writing a try catch helped a lot, right one Let's work, let's go here and see, it is happening till here, why not directly console dialog or what are we getting in the token, let's see once, okay, this is how I will make the token, okay, look guys, trial and error, I told you, this is how work happens in real, I go back here, refresh it, okay, I click on it, okay, look, I get the mail, the mail is coming to me regularly, there is no tension, the real email comes, I open it, look, here I am getting something like this, so somewhere on the token, oh my God, look guys, look, look, there is no problem, that means I am getting the token but we did not handle the promise properly, that's the only problem, there is no other problem, only that one problem is happening here, so guys, how are you feeling, is this how much oh sum and this is the reality, guys, it is not like that whenever I am writing the code, there is never any error and we do it, it is not like that while we are making the video Yes, I have done a lot of practice behind it. I have my team and we practice together and only then I will put that code in front of you guys. I am not coding it on the spot. If I do it on the spot then who knows how many errors will come up and what will happen. But still look, I got an error and where did the mistake happen? I will tell you, first of all, the mistake happened and we did not get anything at all. At least a try and then catch. When we used it, somehow it figured it out and at least gave us that link. And when we got the link, we got to know that everything is correct. There is just one problem where this was not there. There was something like this where it is clearly visible that this is also there and we also have this. It was just some problem with the promise as well. So we got to know that the mail is correct but there is something wrong with the token. So I got the token consoled. When we consoled the token, I was getting that eight digit token but there was a promise attached to it. So it means that there is a problem here. It is happening okay because when we are passing it, it is equal to random token only, so we passed it, something is going wrong in the generated random token and one problem is that when I am not writing anything here, so why am I making it async here, I should not have made this function an async asynchronous function, this was the only problem and there is no other problem here, so we should not have made it an async function, now I will save control and let's check it out, yes, I am just figuring out that this should be a reason, now I click here and bam guys, see, the token has also come, the link has also come, I will click and boom guys, see, my token has come and my link has come, this is it, so guys, now I will tell you in tomorrow's video some best practices which we could follow so that this error which came today does not come in tomorrow's video, are you understanding, so see, by the way, in today's video, I did not make the error intentionally, to be very frank, it was just a sink by mistake there Added and the kind of error it gave, god knows what the error was, although we could have tackled it but we were not able to figure it out, at least by writing try catch we came to know what was wrong, right? So in tomorrow's video, I will tell you how we can make it better, in which we will see transaction, yes guys, in tomorrow's video, finally in the database, if you have ever heard of transaction while doing a sequence, then now we are going to implement it live in tomorrow's video, it will be a lot of fun, but finally you saw the node mailer, you saw the real, how do you get the link, you got to know all this, where is it coming from, why is it coming, it is good that the error is coming so that you get more idea that how we were getting it, these small things, it is necessary to get errors, otherwise I will tell you that if you write funa fun, then there will be no benefit, you will forget it in a week, then anyway, no, the source code is absolutely free, I will share the link with you in the description and comment section below, if you genuinely If you want to support then guys please like, share and subscribe, but at the same time guys you can get my entry on youtube1, there is a sale going on, in a day or two I am going to do 249, okay, but you have a chance for a day or two, you can try it yourself, okay, you will see, it will increase in two-three days, so this is a good opportunity, you should buy it, I don't know how many of you are still watching this video, but if you are watching it, then congratulations, you have a lot of patience, you will definitely become something in the future, but please subscribe for now and tomorrow's video is very important, don't miss it, I will meet you in tomorrow's video till then guys, thank you so much, take care [Music]
