Question

The function Joi.validate is not defined at this time

I am currently working on creating a validation function for user input

async function validateUserInput(user) {
  const schema = Joi.object({
      password: Joi.string().pattern((new RegExp('^[a-zA-Z0-9]{3,30}$'))),
      repeat_password: Joi.any().equal(Joi.ref('password')).required().messages({ 'any.only': '{{#label}} does not match' }),
      email: Joi.string().email({ minDomainSegments: 2, tlds: { allow: ['com', 'dk']}})
    });
    try {
        const value = await schema.validateAsync((user));
    } catch (err) {
        console.log(err)
    }
  }

However, I am encountering an issue with the repeat_password field,

firstname: 'Mette ',
    lastname: 'Nielsen',
    age: "'35'",
    gender: 'female',
    about: 'I like to go and watch movies',
    email: '<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="9cf1f9e8e8f9f2f5f9f0eff9f2dcaeafaea8a9b2fbfdfbfd">[email protected]</a>',
    password: 'metteNielsen123',
    repeat_password: 'mette',
    likes: 'Shopping, going to the mall, cities',
    dislikes: 'rap musik, events, poor people'

When it comes to validating users, it's important to handle the process correctly.

async function validateUser(user) {
    const schema = Joi.object({
        password: Joi.string().pattern((new RegExp('^[a-zA-Z0-9]{3,30}$'))),
        repeat_password: Joi.any().equal(Joi.ref('password')).required().messages({ 
        'any.only': '{{#label}} does not match' }),
        email: Joi.string().email({ minDomainSegments: 2, tlds: { allow: 
        ['com','dk']}})
     });
     try {
         const value = await schema.validateAsync((user));
     } catch (err) {
         console.log(err)
     }
 }

One way to approach validation is by following this technique:

async function validateUser(user) {
    const schema = Joi.object({
        password: Joi.string().pattern((new RegExp('^[a-zA-Z0-9]{3,30}$'))),
        repeat_password: Joi.any().equal(Joi.ref('password')).required().messages({ 
        'any.only': '{{#label}} does not match' }),
        email: Joi.string().email({ minDomainSegments: 2, tlds: { allow: 
        ['com','dk']}})
     });
     const {error, value} = schema.validate(user)
     // To verify data correctness, check if there are no errors:
     if (!error) {
     // Everything looks good
     } else {
         // You can add a customized error message here
     }
 }
