# Notice

`tcomb-form` is looking for maintainers. If you're interested in helping a great way to get started would just be to start weighing-in on GitHub issues, reviewing and testing some PRs.

# Domain Driven Forms

The [tcomb library](https://github.com/gcanti/tcomb) provides a concise but expressive way to define domain models in JavaScript.

The [tcomb-validation library](https://github.com/gcanti/tcomb-validation) builds on tcomb, providing validation functions for tcomb domain models.

This library builds on those two and **realizes an old dream of mine**.

# Playground

This [playground](https://gcanti.github.io/resources/tcomb-form/playground/playground.html), while a bit outdated, gives you the general idea.

# Benefits

With tcomb-form you simply call `` to generate a form based on that domain model. What does this get you?

1. Write a lot less HTML
2. Usability and accessibility for free (automatic labels, inline validation, etc)
3. No need to update forms when domain model changes

# Flexibility

- tcomb-forms lets you override automatic features or add additional information to forms.
- You often don't want to use your domain model directly for a form. You can easily create a form specific model with tcomb that captures the details of a particular feature, and then define a function that uses that model to process the main domain model.

# Example

```js
import t from 'tcomb-form'

const FormSchema = t.struct({
name: t.String, // a required string
age: t.maybe(t.Number), // an optional number
rememberMe: t.Boolean // a boolean
})

const App = React.createClass({

onSubmit(evt) {
evt.preventDefault()
const value = this.refs.form.getValue()
if (value) {
console.log(value)
}
},

render() {
return (



Save


)
}

})
```

**Output**. Labels are automatically generated.

# Contributions

Thanks so much to [Chris Pearce](https://github.com/Chrisui) for pointing me in the right direction
and for supporting me in the v0.4 rewrite.

Special thanks to [William Lubelski](https://github.com/lubelski) ([@uiwill](https://twitter.com/uiwill)), without him this library would be less magic.

Thanks to [Esa-Matti Suuronen](https://github.com/epeli) for the excellent `humanize()` function.

Thanks to [Andrey Popp](https://github.com/andreypopp) for writing [react-forms](https://github.com/prometheusresearch/react-forms), great inspiration for list management.
