VueJS bindings for gopherjs
Usage
Combined the power of Gopherjs and VueJS, you can use
golang struct to provide the two-way data-binding context for VueJS,
and easily implements the popular browser MVVM models in Go.
Currently ViewModel/Component/Directive/Filter are supported and wrapped in
a gopherjs friendly way.
These are the basic rules to use this package:
-
all
exported fieldsof thegolang structwould become VueJS Instance's data which can be used in the html to do data binding: v-bind, etc -
all
exported funcsof thegolang structwould become VueJS Instance's methods which can be called as html event handler: v-on, etc -
the
golang structtalked above is actually of pointer type and should have an anonymous embeded*js.Objectfield and theexported fieldsshould have properjs struct tagfor bidirectionaly data bindings
Using the debug|dev version of VueJS
This package includes the minified|product version of VueJS code by default,
if you want to include the debug|dev version of of VueJS code, please specify
buidling tags debug to the gopherjs build cmd as this:
gopherjs build --tags debug main.go
for more details please see the examples.
Basic example
gopherjs code:
package main
import (
"github.com/gopherjs/gopherjs/js"
"github.com/oskca/gopherjs-vue"
)
type Model struct {
*js.Object // this is needed for bidirectional data bindings
IntValue int `js:"integer"`
Str string `js:"str"`
}
// this would be recognized as Inc in html
func (m *Model) Inc() {
m.IntValue += 1
println("inc called")
}
// this would be recognized as Repeat in html
func (m *Model) Repeat() {
m.Str = m.Str + m.Str
}
// this would be recognized as Reset in html
func (m *Model) Reset() {
m.Str = "a string "
}
func main() {
m := &Model{
Object: js.Global.Get("Object").New(),
}
// field assignment is required in this way to make data passing works
m.IntValue = 100
m.Str = "a string"
// create the VueJS viewModel using a struct pointer
vue.New("#app", m)
}
html markup:
<!DOCTYPE html>
<html>
<body>
<div id="app" v-cloak>
<div>integer: {{ integer }}
<input v-model="integer"></input>
</div>
<div>str: {{ str }} </div>
<button v-on:click="Inc">Increase</button>
<button v-on:click="Repeat">Repeat</button>
<button v-on:click="Reset">Reset</button>
</div>
<script type="text/javascript" src="basic.js"></script>
</body>
</html>
compile and run, then there you are :)
