# GofeR
A **Go** reactive library inspired by [Vue.js](https://vuejs.org/guide/extras/reactivity-in-depth.html).

## Install
use `go get` to install this package

```shell
go get github.com/nasan016/gofer
```

## Getting Started
To start, define the GofeR package and import the library.

```go
package main

import(
    gf "github.com/nasan016/gofer"
)
```

## Usage
GofeR brings the following reactive primitives from Vue to Go:
* [ref](https://vuejs.org/api/reactivity-core.html#ref)
* [computed](https://vuejs.org/api/reactivity-core.html#computed)
* [watchEffect](https://vuejs.org/api/reactivity-core.html#watcheffect)

## Examples

**Revenue**
```go
package main

import (
    "fmt"
    gf "github.com/nasan016/gofer"
)

func main() {
    price := gf.Ref(2)
    quantity := gf.Ref(1000)

revenue := gf.Computed(func() int {
        return price.GetValue() * quantity.GetValue()
    })

gf.WatchEffect(func() {
        fmt.Println("revenue:", revenue.GetValue())
    })

price.SetValue(price.GetValue() / 2)
    price.SetValue(price.GetValue() * 10)
    quantity.SetValue(quantity.GetValue() + 500)
}

```

**Output**

```shell
revenue: 2000
revenue: 1000
revenue: 10000
revenue: 15000
```

**Increment**
```go
package main

import (
    "fmt"
    gf "github.com/nasan016/gofer"
)

func main() {
    x := gf.Ref(0)
    y := gf.Ref(0)

gf.WatchEffect(func() {
        fmt.Println("x: ", x.GetValue())
        fmt.Println("y: ", y.GetValue())
        fmt.Println("")
    })

increment(x)
    increment(y)
    increment(x)
}

func increment(ref *gf.RefImpl[int]) {
    ref.SetValue(ref.GetValue() + 1)
}

```

**Output**
```shell
x: 0
y: 0

x: 1
y: 0

x: 1
y: 1

x: 2
y: 1
```
