[英]How do you properly use various JS (in this instance svg.js) libraries with vue / @ cli UI?
使用Vue CLI 3 ui,我安装了以下额外的依赖项
但是我似乎无法在应用程序中使用这些库,因为我不清楚如何正确导入它们并在组件之间使用。
main.js中的最新尝试如下:
import Vue from 'vue'
import App from './App.vue'
import router from './router'
import SVG from 'svg.js'
// import connect from 'svg.connectable.js'
// import draggy from 'svg.draggy.js'
Vue.config.productionTip = false
Object.defineProperty(Vue.prototype, '$SVG', { value: SVG });
//Object.defineProperty(Vue.prototype, '$connect', { value: connect });
//Object.defineProperty(Vue.prototype, '$draggy', { value: draggy });
new Vue({
router, SVG,
render: h => h(App)
}).$mount('#app')
在我的组件中,我有以下内容
<template>
<div id="spatialui">
</div>
</template>
<script>
export default {
name: 'spatialui',
props: {
object: Object
}
}
// SVG UI needs
var draw = SVG('spatialui').size(300, 300)
但是,这不适用于控制台抱怨
[vue-router] Failed to resolve async component default: TypeError: element is null vue-router.esm.js:16
[vue-router] uncaught error during route navigation: vue-router.esm.js:16
TypeError: "element is null" vue-router.esm.js:1905
接下来是一堆抱怨svg.js的东西
我试图找到使用该库的正确方法,并且一直在圈子里乱跑,任何指针都值得赞赏。
router.js
import Vue from 'vue'
import Router from 'vue-router'
import start from './views/start.vue'
Vue.use(Router)
export default new Router({
routes: [
{
path: '/',
name: 'start',
component: start
},
{
path: '/home',
name: 'home',
component: () =>
import(/* webpackChunkName: "home" */ "./views/home.vue")
},
{
path: '/about',
name: 'about',
component: () =>
import(/* webpackChunkName: "about" */ "./views/about.vue")
}
]
})

事实证明它非常简单
使用Vue CLI UI添加所需的库。 然后用这一行导入它们
import SVG from 'svg.js'
进入希望使用该库并使用已安装功能的组件
<template>
<div id="spatialui">
<!-- the SVG.js stuff appears here -->
</div>
</template>
<script>
import SVG from 'svg.js'
export default {
name: 'spatialui',
props: {
object: Object
},
mounted: function() {
// SVG UI needs
var draw = SVG('spatialui').size(600, 300)
var rect_1 = rect(50, 50).attr({ fill: '#f06' })
}
</script>
