React Enquiry

Enquiry a the form validation framework for React you can already use if you know how HTML and forms work. Simply wrap your <input /> element in an enquiry/form and you're ready go.

Check the documentation site for examples and documentation!

Architecture

Enquiry recursively wraps your form components in an higher-order-component that captures validation properties and change listeners. These HOC components are then registered with the containing form component to easily retrieve validation results and values on a single onSubmit handler.

Enquiry makes it easy to create re-usable form sub-sections by attaching child-wrappers using refs.

Installation

    npm install enquiry

Usage

The documentation site is a showcase of enquiry's features.

Getting values from input elements

Geting all the values from your form is as un-exiting as simply replacing the <form> tag with enquiry/from:

const Form = require("enquiry/form");
const React = require("react");

// values will be an object containing {name, password}
// errors can be an object of {name, password}
function onSubmitRegisterForm(errors, values) {
    if (errors) return alert(`Your form was invalid! ${JSON.stringify(errors)}`);
    return alert(`Your form was valid! ${JSON.stringify(values)}`);
}

function RegisterFrom() {
    return (
        <Form onSubmit={onSubmitRegisterForm}>
            <label>Your name: </label>
            <input name="name" />
            <label>Choose a password: </label>
            <input name="password" type="password" />
            <button>submit</button>
        </Form>
    );
}

Validating values from input elements

You can supply a validation property to your input elements, comprising of either one single function or an array of functions.

Validation functions will be executing in order, returning at the first failed validation. A validation function should return a single string if validation fails.

Validation functions receive two arguments: the value of the field being checked, and the values of all other fields as a key => value object.

For more advanced examples plese refer to the documentation site

Example:

const Form = require("enquiry/form");
const React = require("react");

function isRequired(value) {
    if (!value) return "This is a required field";
}

function isPositiveInt(value) {
    if (!/^\d+$/.test(value)) return "This must be a positive int";
}

function AgeForm() {
    return (
        <Form onSubmit={onSubmitNameForm}>
            <label>How old are you?: </label>
            <input name="age" validation={[isRequired, isPositiveInt]} />
            <button>submit</button>
        </Form>
    );
}
