Model Validator | React components

Project Helper for Model Validator - a basic set of UI components, React, to use.

Installation

• npm install -D lx-model-validator
• npm install -D lx-model-validator-react

Usage

For sure, you can use raw Model Validator functions, but I find it more convenient to have common react components for common tasks.

This package is for them. Just bindings: headless components that use Model Validator helpers.

Headless means that they do not contain any CSS styles.

ValidationMessageComponent

This is the root component to display the violations.

type TValidationMessageComponentProps = {
	type?: 'error' | 'warning' | 'notice'
	field?: string
	result?: TValidationResult
}
const ValidationMessageComponent: React.FC<TValidationMessageComponentProps> = (...) => {
	...
	return <div className={'validation-messages ' + type}>
		{allMessages.map((messageKey: string, idx:number) => {
			return <div className={'validation-message'} key={idx}>{messageKey}</div>;
		})}
	</div>;
};

Properties:

• type, one of error, warning or notice, dfefault error`,
• field to check (the key in terms of Validator's helper functions),
• result to process.

Usage:

<fieldset>
	<label htmlFor="name">Name</label>
	<input className={'validation-' + getValidationClass(validationResult, 'name')}
		type="text"
		id="name"
		onChange={(e) => handleChange('name', e)}
		value={model.name}/>

	<ValidationMessageComponent field={'name'} result={validationResult}/>
</fieldset>

ValidationAnyMessageComponent

This is the dispatching component. As you can see, it just wraps up the calls of ValidationMessageComponent with corresponding settings:

type TValidationAnyMessageComponentProps = {
	field?: string
	types?: Array<string> // 'error' | 'warning' | 'notice'
	result?: TValidationResult
}
const ValidationAnyMessageComponent: React.FC<TValidationAnyMessageComponentProps> = ({...}) => {
	return <>
		{(!types || types.includes('error')) &&
			<ValidationMessageComponent type={'error'} field={field} result={result}/>}

		{(!types || types.includes('warning')) &&
			<ValidationMessageComponent type={'warning'} field={field} result={result}/>}

		{(!types || types.includes('notice')) && 
		    <ValidationMessageComponent type={'notice'} field={field} result={result}/>}
	</>;
};

Properties:

• field to check (the key in terms of Validator's helper functions),
• optional types,
• result to process.

This is an extended version of ValidationMessageComponent which allows you to display not just one type of violations (errors, warning, notices) but the required set.

Usage:

<h1>Errors:</h1>

<ValidationAnyMessageComponent result={validationResult}/>

ValidationErrorMessageComponent

Wrapper for <ValidationMessageComponent> with predefined type={'error'}

ValidationWarningMessageComponent

Wrapper for <ValidationMessageComponent> with predefined type={'warning'}

ValidationNoticeMessageComponent

Wrapper for <ValidationMessageComponent> with predefined type={'notice'}

ValidationTooltipComponent

This component is designed to work together with React tooltip component.

type TValidationTooltipComponentProps = {
	field: string
	component: any
	result?: TValidationResult
	showOk?: boolean
	showNumber?: boolean
}
const ValidationTooltipComponent: React.FC<TValidationTooltipComponentProps> = (...) => {
	if (!result) {
		return null;
	}

    ...

	return <div className={'validation-tooltip ' + level}>
		<a data-tooltip-id={'validation-' + field} className={showNumber ? 'with-number' : ''}>{showNumber ? count : ''}</a>
		{element}
	</div>;
};

Properties:

• field to check (the key in terms of Validator's helper functions),
• component – target component which children will be replaced with

  <ul>
      {errors?.map(str => <li key={str}>{str}</li>)}
      {warnings?.map(str => <li key={str}>{str}</li>)}
      {notices?.map(str => <li key={str}>{str}</li>)}
  </ul>

• result to process,
• showOk to display the component even if there are no errors:

  <div className={'validation-tooltip ok'}>
      <a data-tooltip-id={'validation-' + field}></a>
  </div>

• showNumber to output the number ov violation inside <a></a> tag.

Usage:

<fieldset>
	<label htmlFor="name">Name</label>
	<div className={'field-with-tooltip'}>
		<input
			className={'validation-' + getValidationClass(validationResult, 'name')}
			type="text"
			id="name"
			onChange={(e) => handleChange('name', e)}
			value={model.name}/>

		<ValidationTooltipComponent
			field={'name'}
			showOk={showOk}
			showNumber={showNumber}
			result={validationResult} component={<Tooltip place={'right'}/>}/>
	</div>
</fieldset>
