Validation

Simple, easy to use and small size package for validation

Installation

npm install edhi_validation

Usage

Using synchronous validation

import Rules, { validateAll } from 'edhi_validation';

class UserSchema {
	id = new Rules({ default: 1 }).isNumber();
	fullname = new Rules().isRequired().isString();
	age = new Rules().isRequired().isNumber();
}

const data = {};

validateAll(UserSchema, data); // { fullname: [ 'The field fullname is required', 'The field fullname must be a string' ], age: [ 'The field age is required', 'The field age must be a number' ] }

data; // { id: 1 }

Using asynchronous validation

import Rules, { validateAllAsync } from 'edhi_validation';

class CredentialSchema {
	email = new Rules({ name: 'E-mail' })
		.isRequired()
		.isEmail()
		.newRule(
			async () => false,
			(name: string) => `The field ${name} is already exists`
		);
	password = new Rules().isRequired().isString().isMin(6);
}

const data = {
	email: '[email protected]',
};

(async () => {
	await validateAllAsync(CredentialSchema, data); // { email: [ 'The field E-mail is already exists' ], password: [ 'The field password is required', 'The field password must be a string', 'The field password minimum is 6' ] }
	data; // { email: '[email protected]' }
})();

The arrangement of rules from schema will be the arrangement of error massages

  ...
  password = new Rules().isString().isMin(6).isRequired();
  ...

  ...
  await validateAllAsync(CredentialSchema, data); // { email: [ 'The field E-mail is already exists' ], password: [ 'The field password must be a string', 'The field password minimum is 6','The field password is required' ] }
  ...
