Using ES6 modules without Webpack
If you are working with ES6 then you should NOT manually inserting your main.js into index.html - this will be handled by Webpack. Actually, the simplest tutorial for Vue goes like this:
- npm install -g vue-cli
- vue init webpack my_project
- npm run dev (and start developing - result is available on http://localhost:8080)
- npm run build (result is available inside the
./dist folder of your project
Also, you should import Vue like this
import Vue from 'vue';
and not like this
import Vue from '../../node_modules/vue';
EDIT
Okay, if you insist on going through the beginners' path and not using Webpack and single-file Vue components - then you should start like this:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1" />
<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0" />
<title>My beginners project</title>
<link rel="stylesheet" type="text/css" href="/assets/css/styles.css" />
</head>
<body>
<div id="app">
<router-view></router-view>
</div>
<!-- templates for your components -->
<template id="login">
<div>test</div>
</template>
<script src="https://cdn.jsdelivr.net/npm/vue@2.5.17/dist/vue.js"></script>
<script src="https://unpkg.com/vue-router@3.0.1/dist/vue-router.js"></script>
<!-- code for your components -->
<script type="text/javascript" src="/app/login.js"></script>
<!-- Vue Root component should be last -->
<script type="text/javascript" src="/app/app.js"></script>
</body>
</html>
And your /app/app.js will look like this:
var badRoute = Vue.component('bad-route', {
template: '<div id="bad_route"><h1>Page Not Found</h1><p>Sorry, but the page you were trying to view does not exist.</p></div>'
});
var vue_router = new VueRouter({
base: '/app'
, mode: 'hash'
, routes: [{
path: '/'
, redirect: '/login'
}, {
path: '/login'
, component: loginForm
, name: 'LOGIN'
}, {
path: '*', // should be last, otherwise matches everything
component: badRoute
, name: 'NOT FOUND'
}]
});
// Main application
var vue_app = new Vue({
router: vue_router
, })
.$mount('#app');
And your /app/login.js component will look like this:
var loginForm = Vue.component('login-form', {
template: '#login', // should match the ID of template tag
data: function() {
var a = {
username: ''
, password: ''
, };
return a;
}
, methods: {}
});
