UFS 📮

Elegant, lightweight form validation and processing for React and React Native.

Installation

npm install @uptimeventures/ufs-react @uptimeventures/ufs-dom

Getting Started

UFS comes in two parts: the main wrapping component (@uptimeventures/ufs-react) and platform-native visual components (like @uptimeventures/ufs-dom). Together, these components can be used to create cross-platform user interfaces. Here's a brief example:

import React from 'react'
import Form from '@uptimeventures/ufs-react'
import { Input } from '@uptimeventures/ufs-dom'

const App = () => (
  <Form
    handleSubmit={handleSubmit}
    validate={validate}
  >
    {({ handleSubmit }) => (
      <Input
        label="Name"
        name="name"
        required
      />
      <Input
        label="Email Address"
        name="email"
        type="email"
        required
      />
      <button> {/* Available since we're rendering on DOM */}
        Submit
      </button>
    )}
  </Form>
)

const validate = ({ name, email }) => ({
  name: !name ? 'Please provide your name.' : undefined,
  email: !email ? 'Please provide your email.' : undefined,
})

const handleSubmit = values => {}

In fact, you can break down components even further: <Form/> accepts a component prop that makes the syntax above even cleaner.

Eventually, we'll release bindings for React Native. But there's no technical constraint in the way.

Why create another form library?

Existing solutions were either too large (requiring Redux or another state management solution often just to manage forms), or relied heavily on browser-centric handlers. While React Native's event system mirrors most of the events and structure provided by React DOM, a few key differences exist.

The tooling and handler pattern proposed in UFS allows developers to be incredibly productive by reusing most of the logic for all platforms.

Status

UFS is being developed alongside several internal projects at Uptime Ventures, so expect frequent API changes prior to 1.0.0.

What's with the name?

UFS: Universal Form System. Also known as the Uptime Form System, named after Uptime Ventures, the Denver, Colorado digital consultancy.
