Not React.js for Golang!

`go-react` is a library for data binding.

[See here for earlier version of Golang](https://github.com/Nomango/go-react/tree/v1).

## Install

```bash

go get github.com/Nomango/go-react/v2

```

## Usage

```golang

ch := make(chan int)

// Create a source

s := react.NewChanSource(ch)

// Create a value and bind with the source

vInt := react.NewValue[int]()

cancel := vInt.Bind(s)

// A binding can be canceled

defer cancel()

// Set action on change

vInt.OnChange(func(i int) {

    fmt.Println(i)

})

// A source can be bound more than one time

// So the following code is valid

vInt2 := react.NewValueFrom(0)

vInt2.Bind(react.NewBinding(s.Binding(), func(v int) int {

    return v + 1 // Processing raw value

}))

// Bind another value

vInt32 := react.NewValue[int32]()

vInt32.Bind(react.NewBinding(vInt.Binding(), func(v int) int32 {

    return int32(v + 1)

}))

// Convert a int value to a string value

asyncBinding := react.NewAsyncBinding(vInt.Binding(), func(v int) string {

    return fmt.Sprint(v + 3) // Processing in a separate goroutine

})

vStr, _ := react.NewBindingValue(asyncBinding)

// Send a value to Source

ch <- 1

// Wait for the update to complete

time.Sleep(time.Millisecond * 10)

fmt.Println(vInt2.Load())

fmt.Println(vInt32.Load())

fmt.Println(vStr.Load())

// Output:

// 1

// 2

// 3

// 4

```
