validator-pyrobyte

Installation

npm install --save validator-pyrobyte

Example

import {Validator} from 'validator-pyrobyte';

let rules = {
  text: {
    required: true,
    minLength: 10,
  },
  phone: {
    phone: true,
  },
};

let validator = new Validator(rules);
let validationText = validator.check('text', valueText); // return IResultValidation
let validationAll = validator.checkAll({
  text: 'text',
  phone: '[phone]',
}); // return IResultValidation

Constants

type RULES_VALIDATION:

type TRuleValidation<Data = any> = {
  handler(v: Data, param?: number): boolean,
  errorText(param: number): string,
};

interface IRulesValidation {
  [nameRule]: TRuleValidation,
}

import {RULES_VALIDATION} from 'validator-pyrobyte';

let rules: IRulesValidation = RULES_VALIDATION;

Methods

Result methods validation check and checkAll:

interface IResultValidation {
  passed: boolean,
  errors: string[],
}

Check

type check<Data> = (nameRule: keyof Rules, data: Data) => IResultValidation;

CheckAll

import {IRules} from "./index";

type ValidatorData<Rules> = {
  [Property in keyof Rules]: string;
};

type  checkAll<Data> = (data: ValidatorData<Rules>) => IResultAllValidation<Rules>;

ChangeRule

type changeRule<Data> = (
  nameRule: string,
  handler: ValidatorHandler<Data>,
  errorText: string
) => void;

import {Validator} from 'validator-pyrobyte';

let validator = new Validator({
  text: {
    isText: true,
  },
});
// new rule
validator.changeRule('new', (v) => !!v, 'some error text');

// change default rule
validator.changeRule('isText', (v) => /^(\d/.test(v), 'new error text');
