#React Form Thing
A library for writing dynamic React forms with ease.
formerly
gives you a very flexible and idiomatic way to structure your forms
<Form ref='form' onSubmit={this.onSubmit}>
<label>Your name</label>
<Input name='myName' value='nicolas cage' />
<label>Your best friend name</label>
<Input name='bestFriend' shouldEqual='Obama' value='None' />
<label>Are you older than 18?</label>
<Input type='checkbox' name='is18Plus'/>
<label>Your usual password</label>
<Input type='password' name='password' />
<label>Repeat your password</label>
<Input type='password' name='repeatPassword' />
<!-- zero boilerplate way to bind a random component to any input anywhere in your form -->
<OnValue in={['password', 'repeatPassword']} test={({password, repeatPassword}) => password === repeatPassword}>
<!-- when using a custom component, "value" is passed as "props" -->
Congratulations, you can type
</OnValue>
<Entity name='addresses'>
<Entity name='home'>
<label>Home address</label>
<Input name='streetAddress' value='1600 Pennsylvania Ave NW, Washington, DC 20500, United States' />
<Input name='reference' value='Largest house in the block' />
</Entity>
<Entity name='hideSpot'>
<label>Secret hide spot</label>
<Input name='streetAddress' placeholder='Please fill this one' required />
<OnError in='streetAddress'>
You really should fill this one
</OnError>
<Input name='reference' />
</Entity>
</Entity>
<label>Emails</label>
<Entity name='emails'>
<Input name={0} type='email' value='[email protected]' />
</Entity>
<label>Favorite music</label>
<Select name='music'>
<option>Country</option>
<option>Rap</option>
</Select>
<button type='submit'>Submit</button>
</Form>
and a clean API
