Vue学习笔记(十五)——搭建基于webpack的vue开发环境

参考文档:https://segmentfault.com/a/1190000012789253?utm_source=tag-newest

依次执行文档贴出的命令即可完成基于webpack的vue开发环境的搭建,如果无法成功搭建(如某一步骤发生错误)请在文档下留言以便笔者更正。

package.json(如果无法成功搭建,请先检查组件版本)

{
  "name": "webpack-vue",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "dev": "webpack-dev-server --open --hot",
    "build": "webpack --progress --hide-modules"
  },
  "author": "",
  "license": "ISC",
  "dependencies": {
    "html-webpack-plugin": "^3.2.0",
    "vue": "^2.6.10",
    "vue-loader": "^15.7.0",
    "vue-template-compiler": "^2.6.10",
    "webpack": "^4.34.0",
    "webpack-cli": "^3.3.4",
    "webpack-dev-server": "^3.7.1"
  }
}

环境准备(首先搭建webpack环境,故vue会在后面的步骤安装)

1.初始化工程:

npm init

2.安装webpack

npm install webpack

3.安装webpack-cli

npm install webpack-cli

4.安装webpack-dev-server

npm install webpack-dev-server

5.安装html-webpack-plugin

npm install html-webpack-plugin

6.替换工程根目录下package.json文件scripts的值:

  "scripts": {
    "dev": "webpack-dev-server --open --hot",
    "build": "webpack --progress --hide-modules"
  }

7.在工程根目录下新增webpack.config.js文件,内容如下:

'use strict';
const path = require("path");
const HtmlWebpackPlugin = require('html-webpack-plugin');

module.exports = {
    entry: {
        "main": "./src/main.js"
    },
    output: {
        path: path.resolve(__dirname, "build"),
        filename: "[name].js"
    },
    devServer: {
        historyApiFallback: true,
        overlay: true
    },
    plugins: [
        new HtmlWebpackPlugin({
            template: 'index.html',
            inject: 'body'
        }),
    ]
};

工程代码

1.在根目录下新增index.html:


<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Titletitle>
head>
<body>
<div id="app">div>
body>
html>

2.在根目录下新增src目录,并在src目录下新增main.js:

document.getElementById("app").innerHTML = "app info";

检查环境

1.运行工程

npm run dev

页面正常:

引入vue

1.安装vue

npm install vue

2.调整index.html:


<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Titletitle>
head>
<body>
<div id="app">
    {{message}}
div>
body>
html>

3.调整main.js:

import Vue from 'vue'

new Vue({
    el: '#app',
    data: {
        message: "app info"
    }
});

检查引入vue后的环境

1.运行工程:

npm run dev

页面控制台报错:

[Vue warn]: You are using the runtime-only build of Vue where the template compiler is not available. Either pre-compile the templates into render functions, or use the compiler-included build.

如下图:

这是由于直接import Vue from 'vue’使用的是vue的运行时版本,而开发时通常需要使用vue的完整版本。

2.在webpack.config.js增加以下代码(用于引用vue的完整版本):

    resolve: {
        alias: {
            'vue$': 'vue/dist/vue.esm.js'
        }
    }

2.再次运行工程:

npm run dev

页面恢复正常(这里不再重复贴图)。

支持引入.vue文件

1.安装vue-loader

npm install vue-loader

2.安装vue-template-compiler

npm install vue-template-compiler

3.更新webpack.config.js(用于引用vue-loader):

'use strict';
const path = require("path");
const HtmlWebpackPlugin = require('html-webpack-plugin');
const VueLoaderPlugin = require('vue-loader/lib/plugin');

module.exports = {
    entry: {
        "main": "./src/main.js"
    },
    output: {
        path: path.resolve(__dirname, "build"),
        filename: "[name].js"
    },
    devServer: {
        historyApiFallback: true,
        overlay: true
    },
    resolve: {
        alias: {
            'vue$': 'vue/dist/vue.esm.js'
        }
    },
    module: {
        rules: [
            {
                test: /\.vue$/,
                loader: 'vue-loader'
            }
        ]
    },
    plugins: [
        new HtmlWebpackPlugin({
            template: 'index.html',
            inject: 'body'
        }),
        new VueLoaderPlugin()
    ]
};

4.新增自定义组件component-a:

<template>
    <span>it is component a</span>
</template>

<script>
    export default {
        name: "component-a"
    }
</script>

<style scoped>

</style>

5.调整main.js(引用组件component-a):

import Vue from 'vue'
import ComponentA from './components/ComponentA.vue'

new Vue({
    el: '#app',
    components: { ComponentA },
    template: ''
});

6.调整index.html:


<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Titletitle>
head>
<body>
<div id="app">
div>
body>
html>

7.运行工程:

npm run dev

页面正常(组件正常显示):

至此一个基于webpack的基础vue开发环境就搭建完成了。
