Form Request Validation

A simple and flexible form validation library that allows you to send any request and validate it against customizable field options. Easily define validation rules, patterns, and error handling for various forms and fields.

Installation

To install the package, use npm:

npm install form-request-validation

or with yarn:

yarn add form-request-validation

Usage

First, you need to configure your AWS credentials to allow the package to send emails using AWS SES. This can be done by setting up environment variables:

import { validateEmailRequest, LanguageValidationRules, ValidationRules } from 'form-request-validation'

const fieldOptions = {
  emailFrom: {
    name: 'Email From',
    required: true,
    validation: true,
    minLength: 1,
    maxLength: 500,
    pattern: /^[a-z0-9._%+-]+@[a-z0-9.-]+\.[a-z]{2,4}$/i,
    errorMessage: 'Please provide a valid email address',
  },
  subject: {
    name: 'Subject',
    required: false,
    validation: true,
    pattern: createValidationRegex(LanguageValidationRules.LatinAlphabetPattern, LanguageValidationRules.EstonianPattern, ValidationRules.SpecialCharacterPattern),
    errorMessage: 'Please provide a valid subject',
  },
}

const defaultFieldOptions = {
  subject: {
    name: 'Subject',
    required: false,
    validation: true,
    pattern: createValidationRegex(LanguageValidationRules.LatinAlphabetPattern),
    errorMessage: 'Please provide a valid subject',
  }
}

const formRequest = {
  emailFrom: 'user@example.com',
  subject: 'Contact Us Form Submission',
  message: 'This is a test message from the contact form.',
}

const validationErrors = validateEmailRequest(formRequest, fieldOptions, defaultFieldOptions)
if (validationErrors.length > 0) {
  throw Error(JSON.stringify(validationErrors))
}
