Validate phone number with Yup?

>. Update .<

http://yup-phone.js.org/

I've created a yup-phone module that uses google-libphonenumber which gives accurate validation checks and can be installed directly from github

npm install --save yup yup-phone.

Check Usage

const Yup = require('yup');
require('yup-phone');

// validate any phone number (defaults to India for country)
const phoneSchema = Yup.string().phone().required();
phoneSchema.isValid('9876543210'); // → true

From Simple React Validator,

The regex for phone number validation is

/^(\+?\d{0,4})?\s?-?\s?(\(?\d{3}\)?)\s?-?\s?(\(?\d{3}\)?)\s?-?\s?(\(?\d{4}\)?)?$/

Example

// index.js

const yup = require('yup');
const { rePhoneNumber } = require('./yup-phone')

const schema = yup.string().phone()

const phone = '+911234567890';
console.log('Is Valid? ', rePhoneNumber.test(phone)); // Is Valid? true
schema.validateSync(phone);

// yup-phone.js

const yup = require('yup');

const rePhoneNumber = /^(\+?\d{0,4})?\s?-?\s?(\(?\d{3}\)?)\s?-?\s?(\(?\d{3}\)?)\s?-?\s?(\(?\d{4}\)?)?$/;

module.exports.rePhoneNumber = rePhoneNumber

yup.addMethod(yup.string, "phone", function() {
  return this.test("phone", "Phone number is not valid", value =>
    rePhoneNumber.test(value)
  );
});

Hi right now I'am solving same problem as you and I found possible solution.

Validate phone number with string that matches Regex

const phoneRegExp = /^((\\+[1-9]{1,4}[ \\-]*)|(\\([0-9]{2,3}\\)[ \\-]*)|([0-9]{2,4})[ \\-]*)*?[0-9]{3,4}?[ \\-]*[0-9]{3,4}?$/

phoneNumber: Yup.string().matches(phoneRegExp, 'Phone number is not valid')

You can search for different Regex Expressions and validate it. I've used Regex from this article https://www.sitepoint.com/community/t/phone-number-regular-expression-validation/2204

Try this, it might be helpful for you.

mobile: Yup.string().matches(/^[6-9]\d{9}$/, {message: "Please enter valid number.", excludeEmptyString: false})

const phoneRegExp = /^((\\+[1-9]{1,4}[ \\-]*)|(\\([0-9]{2,3}\\)[ \\-]*)|([0-9]{2,4})[ \\-]*)*?[0-9]{3,4}?[ \\-]*[0-9]{3,4}?$/


phone_number: Yup.string()
  .required("required")
  .matches(phoneRegExp, 'Phone number is not valid')
  .min(10, "to short")
  .max(10, "to long"),

This works best for me...you can set your own length...i just wanted 10 digits not less or more
