🧑‍⚖️ Form validation rule list

This utility package allows to add a visual validation feedback to your users. It exposes a Higher Order Component adding some behavior to your existing inputs.

❓ Why ?

By default, you can already validate your forms without adding any other library to the mix. It is also very trivial to display some error message since every dictionary component are receiving it from props. So why would you need something like form validation rule list ? To give your users some hints about what is going wrong with their typing. It's too often that we apply several validations rules on a single input and many of those rules are complaining at the same time, then what to display ?

🏗️ Install

npm install @bedrockstreaming/form-validation-rule-list

🚀 Usage

Extra validation

const extraValidation = {  oneUpperCaseCharacter: () => (fieldValue) => /(?=.*[A-Z])/.test(fieldValue),  minLength: (minLengthValue) => (fieldValue) =>    fieldValue && fieldValue.length >= minLengthValue,};

Schema

const schema = {  fields: {    password: {      id: 'password',      type: 'password',      validation: {        oneUpperCaseCharacter: {          key: 'oneUpperCaseCharacter',          message: 'You need at least one upper cased character',        },        minLength: {          key: 'minLength',          message: 'You password should be minimum 12 characters long',          value: 12,        },      },    },  },  steps: {...},  stepsById: [...]};

Dictionary

import {  getValidationRulesHints,  checkRules,  withValidationRuleList,} from '@bedrockstreaming/form-validation-rule-list';
import { PasswordTextField } from '@mylib/textfield';
const ValidatedPasswordTextField = withValidationRuleList(PasswordTextField);
const dictionary = {  password: ({ errors, validation, label, ...props }) => {    // These rules don't match react-hook-form's rule API, its proper to the form-validation-rule-list package    const rules = getValidationRulesHints({      errors,      validation,    });
    const hasError = !!checkRules(props.value, rules).length;    const fieldError = errors && errors.type;    const isValid = !!(props.value && !hasError && !fieldError);
    return (      <div>        <ValidatedPasswordTextField          label={label}          hasError={hasError}          valid={isValid}          {...props}          // specific props required by ValidationRuleList          rules={rules}          colors={validationColors}        />      </div>    );  },};

⚠️ Beware, you can't use several react-hook-form default rules as validation hints since the errors object returned by the library can only contain one default rule error at a time.
