Coverage Status

Formol is a full featured object edition form framework for React.

  • Native field types
  • Powerful non-native field types, based on well known libraries:
  • Enhanced native dom validation with cross field validation support
  • Dynamic forms with dynamic field attributes based on fields values
  • Lightweight (20kb gz) with webpack code-splitting (total: ~600kb gz)
  • Support style theming (with currently two bundled)
  • Works well with unrest and redux-api-unrest

Quick start

yarn add formol

To use webpack code-splitting in formol, you will have to do these modifications to your webpack.config:

module: {
  rules: [
    {
      test: /\.(mjs|jsx?)$/,
      exclude: /node_modules\/(?!(formol)\/).*/, // <- this line allows formol
      use: {                                     //    to be built alongside
        loader: 'babel-loader',                  //    your project
      },
      options: {
        presets: [
          '@babel/preset-react',
          [
            '@babel/preset-env',
            {
              targets: { browsers: 'last 1 version and > 3%' },
              modules: false,
            },
          ],
        ],
        plugins: [ // <- these plugins are needed to build formol
          '@babel/plugin-syntax-dynamic-import',
          ['@babel/plugin-proposal-decorators', { legacy: true }],
          'add-react-static-displayname',
          ['@babel/plugin-proposal-class-properties', { loose: true }],
        ],
      },
    },
  ],
},
resolve: { // <- these extensions needed to be loaded by webpack
  extensions: ['.mjs', '.js', '.jsx'],
},

NB: It is also possible to use the prebuilt version of formol, in this case you will have to copy the javascript files in node_modules/formol/lib in your output.path instead of modifying your webpack config.

Now you are all set.

But before going too deep, let’s take a look at the two following exemples:

Simple and elegant

import 'formol/lib/default.css'
import Formol, {Field} from 'formol'

const onSubmit = ({ login, password }) =>
  doLogin(login, password)

<Formol onSubmit={onSubmit}>
  <Field>Login</Field>
  <Field type="password-strength">Password</Field>
</Formol>

Powerful

const item = {
  firstname: 'John',
  lastname: 'Doe',
  birth: '1988-04-12',
  address: {
    zip: '82937',
    city: 'Los Angeles',
    continent: 'North America',
  },
  fastShipping: true,
  colors: ['#00ffff', '#008000'],
}

<Formol
  item={item}
  validator={({ firstname, lastname }) => ({
    firstname:
      (firstname ? firstname.length : 0) +
      (lastname ? lastname.length : 0) <= 6
        ? 'Your full name must be greater than 6 characters.'
        : null,
  })}
  // eslint-disable-next-line no-alert

Themable

The default theme is accessible by a simple css import (you will need the standard: css loader):

import 'formol/lib/default.css'

similarly with the clean theme:

import 'formol/lib/clean.css'

You can also use directly the sass import if you are using sass:

@import ~formol/src/sass/default

with the added benefit that you can override the formol variables:

$formol-color: #ce93d8
$formol-color-action: #ba68c8
$formol-color-inactive: #e1bee7
$formol-color-error: #f06292
$formol-background-color: #f3e5f5

$formol-font-size: 0.9em

$formol-big-field-size: 70em
$formol-medium-field-size: 50em

$formol-field-margin: 2em
$formol-field-padding: 1.5em

@import ~formol/src/sass/default
