React Advanced Form
[React Advanced Form](https://github.com/kettanaito/react-advanced-form) is a library for tailoring real-world forms in [React](https://reactjs.org/) with pleasure and ease.
---
# Features
## Expectations shift
Trust and expect a form to do more than just rendering the fields. Our features are designed to handle cumbersome use cases with clean and performant code
## Immutable
Each field interaction or update is a pure function that produces the next state of a field.
## [Composite fields](https://redd.gitbook.io/react-advanced-form/getting-started/creating-fields)
React Advanced Form is _field-centric_. That means you define flexible fields composites and reuse them throughout the application. Reflect even the most granular field state changes in the UI to achieve the outmost user experience.
```jsx
import React from 'react'
import { createField, fieldPresets } from 'react-advanced-form'
const Input = ({ fieldState, fieldProps }) => {
const { valid, invalid } = fieldState
const classNames = [valid && 'has-success', invalid && 'has-error'].filter(
Boolean,
)
return
}
export default createField(fieldPresets.input)(Input)
```
## Clean and fast
Develop production-ready forms in a speed of a prototype.
```jsx
// This is not a diminished example, this is a finite form
```
## [Layered validation schema](https://redd.gitbook.io/react-advanced-form/validation/getting-started)
Select fields and declare validation rules using resolver functions. Utilize the order and priority of their execution to craft validation logic of any complexity.
```js
export default {
type: {
password: {
capitalLetter: ({ value }) => /[A-Z]/.test(value),
oneNumber: ({ value }) => /[0-9]/.test(value),
},
},
name: {
confirmPassword: ({ get, value }) => {
/**
* The "confirmPassword" field will be re-validated whenever
* the "value" prop of "userPassword" field updates.
*/
return value === get(['userPassword', 'value'])
},
},
}
```
Each validation resolver can access respective field's `value`, `fieldProps`, and the `form` as the parameters. It can also reference other field's state via the `get` function, which creates a props subscription to re-evaluate the respective validation rule in real time.
**Say goodbye to crowded** `validate` **functions, welcome clean validation schema**!
## [**Reactive props**](https://redd.gitbook.io/react-advanced-form/architecture/reactive-props)
How much effort would it take you to make one field required based on another field\(s\)? Yes, the correct answer is—_one line of code_:
```jsx
!!get(['lastName', 'value'])} />
!!get(['firstName', 'value'])} />
```
Get as many data from the sibling fields as needed, and build your logic around that. Rely on reactive programming that will re-evaluate a resolver function whenever the referenced field props update.
## [Field grouping](https://redd.gitbook.io/react-advanced-form/components/field-group)
Control the serialized data structure on the layout level by grouping the fields. Take advantage of nested and split groups.
```jsx
```
The form above serializes into the following JSON:
```json
{
"companyName": "Google",
"billingAddress": {
"firstName": "John",
"lastName": "Maverick"
},
"termsAndConditions": true,
"deliveryAddress": {
"firstName": "Catheline",
"lastName": "McCoy"
}
}
```
## Third-party integration
React Advanced Form can be used with **any** third-party fields library by using powerful [`createField`](https://redd.gitbook.io/react-advanced-form/hoc/create-field) API. It also allows to create custom fields from literally any component.
