Express Validator to validate time

I want to validate Time like this 18:14 with express-validator. When i used isTime as stated in validator like this body("StartTime").isTime().withMessage("Value must be time with HH:MM format") throwing an error isTime is not a function.

Is there any other approach to achieve Time validation.

Solution

  • Have you tried Regex?

    const { body, validationResult } = require('express-validator');

body('StartTime')
  .custom((value) => {
    if (!/^([01]\d|2[0-3]):([0-5]\d)$/.test(value)) {
      throw new Error('Value must be time with HH:MM format');
    }
    return true;
  })
