How to format and validate email node js
Solution 1
Use regular expression something like that:
Solution 1:
^[a-zA-Z0-9.!#$%&'*+/=?^_`{|}~-]+@[a-zA-Z0-9](?:[a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?(?:\.[a-zA-Z0-9](?:[a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?)*$
Sample code:
const emailToValidate = '[email protected]';
const emailRegexp = /^[a-zA-Z0-9.!#$%&'*+/=?^_`{|}~-]+@[a-zA-Z0-9](?:[a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?(?:\.[a-zA-Z0-9](?:[a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?)*$/;
console.log(emailRegexp.test(emailToValidate));
Solution 2:
Because you use angular, you are able to validate the email on front-end side by using Validators.email.
If you check angular source code of Validators.email here, you will find an EMAIL_REGEXP const variable with the following value:
/^(?=.{1,254}$)(?=.{1,64}@)[-!#$%&'*+/0-9=?A-Z^_`a-z{|}~]+(\.[-!#$%&'*+/0-9=?A-Z^_`a-z{|}~]+)*@[A-Za-z0-9]([A-Za-z0-9-]{0,61}[A-Za-z0-9])?(\.[A-Za-z0-9]([A-Za-z0-9-]{0,61}[A-Za-z0-9])?)*$/;
You could use it on back-end side too, to validate the input.
Solution 2
You can use email validator module:
var validator = require("email-validator");
validator.validate("[email protected]");
Or, if you don't want any dependencies:
var emailRegex = /^[-!#$%&'*+\/0-9=?A-Z^_a-z{|}~](\.?[-!#$%&'*+\/0-9=?A-Z^_a-z`{|}~])*@[a-zA-Z0-9](-*\.?[a-zA-Z0-9])*\.[a-zA-Z](-?[a-zA-Z0-9])+$/;
function isEmailValid(email) {
if (!email)
return false;
if(email.length>254)
return false;
var valid = emailRegex.test(email);
if(!valid)
return false;
// Further checking of some things regex can't handle
var parts = email.split("@");
if(parts[0].length>64)
return false;
var domainParts = parts[1].split(".");
if(domainParts.some(function(part) { return part.length>63; }))
return false;
return true;
}

Solution 3
In my project i've used email-validator module
npm i email-validator
const emailvalidator = require("email-validator");
if(emailvalidator.validate(req.body.email)){
// Your call to model here
}else{
res.status(400).send('Invalid Email');
}
You can install the module from below link

RAL almost 2 years
I would like that email had format like: [email protected].
Which is the best way to do it?
I have a component for registration and I have the field like this:
<mat-form-field> <input matInput placeholder="Email" name="email" [(ngModel)]="email" required> </mat-form-field>
In my usersRouter I have the function for registration:
router.post('/users/register', (req, res) => { ... const user = new User({ ... email: req.body.email, ... }); ... });
Also, I use mongo and in the UserSchema I have this for the email:
email: { type: String, required: true }
Thanks!

Muhammad Abubakar Zorrain almost 2 yearsthere is a problem with timeout. I use email-validator but sometime it show an error as "{"message":"Please provide a valid email address.","reason":"Timeout"}" so my question is how to get rid of this timeout error. Note: when I send mail to this same address by usying gmail account, it is sending.
