Javascript - Validate phone number with Yup?

To validate a phone number using Yup, you can create a Yup schema with a custom validation function. Here's an example using Yup to validate a phone number:

import * as Yup from 'yup'; const phoneRegExp = /^\+(?:[0-9]��?){6,14}[0-9]$/; const phoneSchema = Yup.string() .matches(phoneRegExp, 'Phone number is not valid') .required('Phone number is required'); // Example usage: const phoneNumber = '+1234567890'; phoneSchema.validate(phoneNumber) .then(valid => console.log('Valid phone number:', valid)) .catch(error => console.error('Invalid phone number:', error.message));

In this example:

  • phoneRegExp is a regular expression representing the allowed format for a phone number. You may need to adjust this based on your specific requirements.
  • phoneSchema is a Yup schema that uses the matches method to enforce the phone number format and the required method to ensure a value is provided.
  • Example usage demonstrates how to validate a phone number using this schema.

Make sure to customize the regular expression phoneRegExp based on the expected format of your phone numbers. The regular expression in the example assumes a format that starts with a plus sign followed by 6 to 14 numeric digits. Adjust it according to your needs.

Examples

  1. How to validate a phone number with Yup in JavaScript?

    // JavaScript with Yup import * as Yup from 'yup'; const schema = Yup.object().shape({ phoneNumber: Yup.string().matches(/^\+(?:[0-9] ?){6,14}[0-9]$/, 'Invalid phone number'), });

    Uses the matches method in Yup to validate a phone number against a regular expression pattern.

  2. Yup validation for optional phone number field in JavaScript

    // JavaScript with Yup import * as Yup from 'yup'; const schema = Yup.object().shape({ phoneNumber: Yup.string().matches(/^\+(?:[0-9] ?){6,14}[0-9]$/, 'Invalid phone number').nullable(), });

    Allows the phone number field to be optional by adding the nullable() method to the Yup validation schema.

  3. Yup validation for a specific country code in a phone number

    // JavaScript with Yup import * as Yup from 'yup'; const schema = Yup.object().shape({ phoneNumber: Yup.string().matches(/^\+1(?:[0-9] ?){9}[0-9]$/, 'Invalid US phone number'), });

    Validates a phone number with a specific country code (e.g., +1 for the United States) using Yup.

  4. Yup validation for phone numbers with or without country code

    // JavaScript with Yup import * as Yup from 'yup'; const schema = Yup.object().shape({ phoneNumber: Yup.string().matches(/^\+(?:[0-9] ?){6,14}[0-9]$|^(\d ?){10,}$/, 'Invalid phone number'), });

    Allows validation for phone numbers with or without a country code using the | (OR) operator in the regular expression.

  5. Yup validation for international phone numbers with or without plus sign

    // JavaScript with Yup import * as Yup from 'yup'; const schema = Yup.object().shape({ phoneNumber: Yup.string().matches(/^\+?(?:[0-9] ?){6,14}[0-9]$/, 'Invalid international phone number'), });

    Validates international phone numbers with or without the plus sign at the beginning.

  6. Yup validation for specific phone number formats in JavaScript

    // JavaScript with Yup import * as Yup from 'yup'; const schema = Yup.object().shape({ phoneNumber: Yup.string().matches(/^(\(\d{3}\) ?|\d{3}-)\d{3}-\d{4}$/, 'Invalid phone number format'), });

    Customizes the phone number validation to a specific format using Yup.

  7. Yup validation for allowing empty phone number field

    // JavaScript with Yup import * as Yup from 'yup'; const schema = Yup.object().shape({ phoneNumber: Yup.string().matches(/^\+(?:[0-9] ?){6,14}[0-9]$/, 'Invalid phone number').nullable(), });

    Allows an empty phone number field using Yup's nullable() method.

  8. Yup validation for handling spaces in phone numbers

    // JavaScript with Yup import * as Yup from 'yup'; const schema = Yup.object().shape({ phoneNumber: Yup.string().transform(value => value.replace(/\s/g, '')).matches(/^\+(?:[0-9] ?){6,14}[0-9]$/, 'Invalid phone number'), });

    Removes spaces from the phone number before validation using Yup's transform method.

  9. Yup validation for accepting both local and international phone numbers

    // JavaScript with Yup import * as Yup from 'yup'; const schema = Yup.object().shape({ phoneNumber: Yup.string().matches(/^(?:\+?(?:[0-9] ?){6,14}[0-9])$|^(?:(?:\d ?){10,})$/, 'Invalid phone number'), });

    Accepts both local and international phone numbers using the | (OR) operator in the regular expression.

  10. Yup validation for phone numbers with optional parentheses

    // JavaScript with Yup import * as Yup from 'yup'; const schema = Yup.object().shape({ phoneNumber: Yup.string().matches(/^\+?(\(\d{3}\) ?)?(?:[0-9] ?){6,14}[0-9]$/, 'Invalid phone number'), });

    Validates phone numbers with optional parentheses for area codes using Yup.
