React Input

Overview

React input is a lightweight, dependency free component for building forms in React without having to think about what happens under the hood. It uses one component and an array of objects that describe the inputs in the form.

Usage

Install the component via npm: npm install react-input.

<Form
  fields={[
    {
      name: 'Email',
      key: 'email',
      type: 'email',
      error: false,
      required: false,
      placeholder: 'Enter an email',
      onChange: value => {
        // handle a changed value on the input
      },
      renderAfter: () => (
        <div>Include an element after the input, which is useful for instructional text or strength meters for passwords</div>
      ),
      renderBefore: () => (
        <div>Include an element before the input</div>
      )
    },
    // additional inputs to include in the form
  ]}
  onChange={state => /* handle form change */ }
  onSubmit={state => /* handle form submit */ }
/>

For a detailed example, see the example project.

Form Props

Name	Type	Description	Required	Default
fields	array	Array of inputs to include	true
labels	boolean	If false, labels are disabled		true
isPending	boolean	If true, an .is-pending class is added to the form		null
isRejected	boolean	If true, an .is-rejected class is added to the form		null
isFulfilled	boolean	If true, an .is-fulfilled class is added to the form		null

The isPending, isRejected and isFulfilled props are useful to add different styles to the form for different states.
