【问题描述】:
我正在尝试将 Vue.js(我也是新手)与现有的 .NET MVC 项目集成。这样我就可以在我认为合适的应用程序的某些区域尝试使用 Vue。
为此,我遵循了一些指南:
- https://medium.com/corebuild-software/vue-js-and-net-mvc-b5cede228626
- https://medium.com/@hyounoosung/integrating-vue-js-2-0-to-net-mvc5-project-f97eb5a5b3ad
到目前为止,似乎一切都很好,但我注意到热重载不起作用。当我运行 webpack 服务器时,我可以看到它正在检测更改并重新编译文件,但浏览器中没有任何反应。事实上,即使我手动刷新或硬刷新页面,也没有任何反应。如果我停止应用程序然后再次运行它,它才会更新。
这是我目前的简单设置...
我有一个新的 MVC 区域,其中有一个视图,具有以下文件夹结构:
WebpackTest/Views/index.html:
<div id="app">
<h3>@ViewBag.Message</h3>
{{ vueMessage }}
</div>
@section Scripts {
<script src="~/bundle/webpacktest.js"></script>
}
然后我有一个包含我的 Vue 代码的脚本文件夹:
scripts/webpacktest/main.js
import Vue from 'vue'
new Vue({
el: '#app',
data() {
return {
vueMessage: 'Message from Vue'
}
}
})
这是我的 package.json:
{
"name": "test",
"description": "test",
"version": "1.0.0",
"author": "Andy Furniss",
"license": "MIT",
"private": true,
"scripts": {
"dev": "cross-env NODE_ENV=development webpack-dev-server --open --hot",
"build": "cross-env NODE_ENV=production webpack --progress --hide-modules"
},
"dependencies": {
"eslint": "^5.9.0",
"vue": "^2.5.11"
},
"browserslist": [

"last 2 versions",
"not ie <= 8"
],
"devDependencies": {
"babel-core": "^6.26.0",
"babel-loader": "^7.1.2",
"babel-preset-env": "^1.6.0",

"webpack": "^3.6.0",
"webpack-dev-server": "^2.9.1",
"eslint-plugin-vue": "^4.7.1"
}
}
...还有我的 webpack.config.js:
var path = require('path')
var webpack = require('webpack')
var fs = require('fs')
var appBasePath = './Scripts/app/'
var jsEntries = {}
// We search for index.js files inside basePath folder and make those as entries
fs.readdirSync(appBasePath).forEach(function (name) {
var indexFile = appBasePath + name + '/main.js'
if (fs.existsSync(indexFile)) {
jsEntries[name] = indexFile
}
})
module.exports = {
entry: jsEntries,
output: {
path: path.resolve(__dirname, './wwwroot/bundle/'),
publicPath: '/wwwroot/bundle/',
filename: '[name].js'
},
module: {
rules: [
{
test: /\.css$/,
use: [
'vue-style-loader',
'css-loader'
],
},
{
test: /\.scss$/,
use: [
'vue-style-loader',
'css-loader',
'sass-loader'
],
},
{
test: /\.sass$/,
use: [
'vue-style-loader',
'css-loader',
'sass-loader?indentedSyntax'
],
},
{
test: /\.vue$/,
loader: 'vue-loader',
options: {
loaders: {
// Since sass-loader (weirdly) has SCSS as its default parse mode, we map
// the "scss" and "sass" values for the lang attribute to the right configs here.
// other preprocessors should work out of the box, no loader config like this necessary.
'scss': [
'vue-style-loader',
'css-loader',
'sass-loader'
],
'sass': [
'vue-style-loader',
'css-loader',
'sass-loader?indentedSyntax'
]
}
// other vue-loader options go here
}
},
{
test: /\.js$/,
loader: 'babel-loader',
exclude: /node_modules/
},
{
test: /\.(png|jpg|gif|svg)$/,
loader: 'file-loader',
options: {
name: '[name].[ext]?[hash]'
}
}
]
},
resolve: {
alias: {
'vue$': 'vue/dist/vue.esm.js'
},
extensions: ['*', '.js', '.vue', '.json']
},
devServer: {
proxy: {
'*': {
target: 'https://localhost:44369/',
changeOrigin: true,
secure: false
},
port: 8080,
host: '0.0.0.0',
hot: true,
inline: true
}
},
performance: {
hints: false
},
devtool: '#eval-source-map'
}
if (process.env.NODE_ENV === 'production') {
module.exports.devtool = '#source-map'
// http://vue-loader.vuejs.org/en/workflow/production.html
module.exports.plugins = (module.exports.plugins || []).concat([
new webpack.DefinePlugin({
'process.env': {
NODE_ENV: '"production"'
}
}),
new webpack.optimize.UglifyJsPlugin({
sourceMap: true,
compress: {
warnings: false
}
}),
new webpack.LoaderOptionsPlugin({
minimize: true
})
])
}
当我更改 main.js 中的消息时,没有任何反应,即使我刷新,即使 webpack 服务器告诉我事情正在发生。
【问题讨论】:
-
如果您进行硬刷新,您的代码更改是否会反映在网页上? (webpack的控制台说编译完成后)
-
不,他们不是。这很奇怪,因为控制台说它已更新 webpacktest.js(这是输出文件)但是当我检查它的内容时,它并没有改变。
-
我现在很困惑。当我转到 localhost:8080/wwwroot/bundle/webpacktest.js 时,我可以看到我的更改,但在 Visual Studio 和应显示更改的实际网页上,它们不存在。
-
@AndyFurniss 你有想过这个吗?我在看同样的问题。下面的答案看起来很复杂,而且这个当前的设置似乎工作得很好,减去了热重载。
