An opiniated react form framework.

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

• Native field types
• Powerful non-native field types, based on well known libraries:
  • react-quill
  • react-select
  • react-dropzone
• 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

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:

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>

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
  onSubmit={item_ => alert(JSON.stringify(item_, null, 2))}
  submitText="Show me the new item"
>
  <Field name="firstname" required>
    First Name
  </Field>
  <Field name="lastname" required minLength={3}>
    Last Name
  </Field>
  <Field
    name="birth"
    type="calendar"
    validator={v =>
      new Date(v) < new Date('1950-01-01')
        ? 'You can’t be too old'
        : ''
    }
  >
    Day of birth
  </Field>
  <Inliner>
    <Field name="address.zip" size={5}>
      Zip code
    </Field>
    <Conditional readOnly={({ address: { zip } }) => !zip}>
      <Field name="address.city">City</Field>
    </Conditional>
  </Inliner>
  <Field
    name="address.continent"
    type="select-menu"
    choices={[
      'Africa',
      'Antarctica',
      'Asia',
      'Europe',
      'North America',
      'Australia/Oceania',
      'South America',
    ]}
  >
    Continent
  </Field>
  <Conditional
    show={({ address: { continent } }) =>
      [
        'Asia', 'North America', 'South America'
      ].includes(continent)
    }
  >
    <Field
      name="fastShipping"
      type="switch"
      title="Fast shipping includes an extra cost"
    >
      Fast shipping
    </Field>
  </Conditional>
  <Conditional
    value={({
        firstname,
        lastname,
        address: { zip, city, continent }
    }) =>
      (firstname ? firstname.length : 0) +
      (lastname ? lastname.length : 0) +
      (zip ? zip.length : 0) +
      (city ? city.length : 0) +
      (continent ? continent.length : 0)
    }
  >
    <Field
      name="price"
      type="money"
      title={
        'This price equals the number of letters ' +
        'in this form (because why not)'
      }
      max={100}
      disabled
      readOnly
    >
      Indicative price
    </Field>
  </Conditional>
  <Field
    name="colors"
    type="checkbox-set"
    choices={Object.entries({
      Red: '#ff0000',
      Yellow: '#ffff00',
      Olive: '#808000',
      Lime: '#00ff00',
      Green: '#008000',
      Aqua: '#00ffff',
      Teal: '#008080',
      Blue: '#0000ff',
      Navy: '#000080',
      Fuchsia: '#ff00ff',
      Purple: '#800080',
    }).map(
      ([k, v]) => [`<div style="color: ${v};">${k}</div>`, v]
    )}
    dangerousRawHTMLLabels
  >
    Choose some colors
  </Field>
</Formol>

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

1. Merge the branches (features, fixes) into master
2. Create release commit:
   1. Update version in package.json according to semantic versioning rules
   2. Update CHANGELOG.md (manually)
   3. Commit these changes as version bump, e.g. v3.0.0
   4. Push commit onto master
3. Tag version bump commit e.g. git tag v3.0.0 and push it git push --tags
4. yarn prepublish
5. npm publish (requires being an npm package maintainer)
6. yarn storybook-deploy
