Date

Validating Date is rather simple but time consuming task, valid8r Date validators provides a handful of options to best suit your validation requirements

Valid8r covers all the basic as well as advanced Date validations that covers 99% edge cases

Start by importing valid8r into your file:

import valid8r from '@c4code/valid8r';

Configuration Options

Valid8r date validator provides handful of options to best meet your requirements and validation needs, the options that can be configured in date validator are:

Typescript

import valid8r from '@c4code/valid8r';

const date: string = "12-12-2024";

// The configuration can be defaulted globally
valid8r.date(date, {
  safe: false, // boolean
  format: "YYYY-MM-DD", // "DD-MM-YYYY" | "MM-DD-YYYY" | "YYYY-MM-DD"
  allowFutureDates: true, // boolean
  allowPastDates: true, // boolean
  requireLeapYear: false, // boolean
  throwErrorsAs: "throw-all", // "throw-first" | "throw-last" | "throw-all",
  /*
  "throw-first" => Throws or returns the first error encountered,
  "throw-last" => Throws or returns the last error encountered,
  "throw-all" => Throws or returns all errors in a Array of string
  */
}); // the second argument is optional

Javascript

The format field accepts the format the date should be in, defaults to 'YYYY-MM-DD'

Can easily be customized to fit your requirement

The Configuration can be globally set for all the validators in your project, know more?

Basic Usage

Here's how we can use the date validator in it's most basic manner:

Start by importing valid8r:

import valid8r from '@c4code/valid8r';

Typescript

import valid8r from '@c4code/valid8r';

const date: string = "12-12-2024";

// The configuration can be defaulted globally
valid8r.date(date); // throws DateValidationFailed error as format is invalid

Javascript

Safe handling

By default, all the validations in valid8r works on unsafe flag, meaning if any of the validation fails it will throw an Error.

However, if you don't want it to throw any error but return them. set the safe flag to true.

Typescript

import valid8r from '@c4code/valid8r';

const date: string = "12-12-2024";

// The configuration can be defaulted globally
const [isValid, errors] = valid8r.date(date, {
    safe: true
});

if (!isValid) {
    console.log(errors);
        // [{ format: "Date format is invalid." }]
}

Javascript

Error Messages

If you don't like the default error message and want to set a custom error message for any specific fields, pass an object as a third argument of the date function:

Typescript

import valid8r from '@c4code/valid8r';

const date: string = "12-12-2024";

// The configuration can be defaulted globally
const [isValid, errors] = valid8r.date(date, {
    safe: true,
    allowPastDates: false,
}, {
    allowPastDates: "Dates from past are invalid!"
});

if (!isValid) {
    console.log(errors);
        // [{ allowPastDates: "Dates from past are invalid!" }]
}

Javascript

Error Message Options

Valid8r date validator provides handful of options to configure error messages to best fit your project requirements

Typescript

import valid8r from '@bitbybit/valid8r';

const username: string = "jo#n_sm1th";

// The configuration can be defaulted globally
valid8r.username(username, { /* Field Configurations */ }, {
  format: 
    "Date format is invalid.", // string
  minDate: 
    "Date is earlier than the minimum allowed date.", // string
  maxDate: 
    "Date is later than the maximum allowed date.", // string
  allowFutureDates: 
    "Future dates are not allowed.", // string
  allowPastDates: 
    "Past dates are not allowed.", // string
  requireLeapYear: 
    "Date is not in a leap year.", // string
}); // the second and third argument is optional

Javascript

All the options are optional, if passed will be used as the configuration for that specific validator

The Error messages can be globally set for all the validators in your project, know more?
