go-react
Not React.js for Golang!
go-react is a library for data binding.
Install
go get github.com/Nomango/go-react
Usage
ch := make(chan int)
// Create a source
s := react.NewChanSource(ch)
// Create a value and bind with the source
vInt := react.NewValue()
cancel := vInt.Bind(s)
// A binding can be canceled
defer cancel()
// Set action on change
vInt.OnChange(func(i interface{}) {
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, func(v interface{}) interface{} {
return v.(int) + 1 // Processing raw value
}))
// Bind another value
vInt32 := react.NewValue()
vInt32.Bind(react.NewBinding(vInt, func(v interface{}) interface{} {
return int32(v.(int) + 1)
}))
// Convert a int value to a string value
asyncBinding := react.NewAsyncBinding(vInt, func(v interface{}) interface{} {
return fmt.Sprint(v.(int) + 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

Types ¶
type Binding ¶
type Binding interface {
// OnChange registers a handler f that handles value changes.
// Note that f should not perform time-consuming operations.
OnChange(f func(interface{})) CancelFunc
}
Binding ...
func NewAsyncBinding ¶
NewAsyncBinding creates a binding that runs in a separate goroutine
type CancelFunc ¶
type CancelFunc func()
A CancelFunc tells an operation to abandon its work. A CancelFunc may be called by multiple goroutines simultaneously. After the first call, subsequent calls to a CancelFunc do nothing.
type Source ¶
type Source interface {
Binding
// Change updates the Source
Change(v interface{})
}
Source ...
func NewTickSource ¶
NewTickSource creates a Source that will send the current time after each tick
type Transform ¶
type Transform func(interface{}) interface{}
Transform converts interface{} to interface{}
type Value ¶
type Value interface {
Binding
// Load ...
Load() interface{}
// Store ...
Store(v interface{})
// Bind creates a binding to this value
Bind(b Binding) CancelFunc
}
Value ...
