一、简介

Vue.js 是什么

Vue.js(读音 /vjuː/, 类似于 view) 是一套构建用户界面的 渐进式框架。与其他重量级框架不同的是,Vue 采用自底向上增量开发的设计。Vue 的核心库只关注视图层,并且非常容易学习,非常容易与其它库或已有项目整合。另一方面,Vue 完全有能力驱动采用单文件组件和Vue生态系统支持的库开发的复杂单页应用。

Vue.js 的目标是通过尽可能简单的 API 实现响应的数据绑定和组合的视图组件。

Vue.js是一个MVVM模式的框架,如果读者有angular经验,一定能够很快入门Vue的

vue.js的特点:

易用: 已经会了HTML,CSS,JavaScript?即刻阅读指南即可开始构建应用!

灵活: 简单小巧的核心,渐进式技术栈,足以应付任何规模的应用。

高效: 16kb min+gzip 的运行大小,超快虚拟 DOM ,最省心的优化

二、环境搭建

vue推荐开发环境:

Node.js: javascript运行环境(runtime),不同系统直接运行各种编程语言

npm: Nodejs下的包管理器

webpack: 它主要的用途是通过 CommonJS 的语法把所有浏览器端需要发布的静态资源做相应的准备,比如资源的合并和打包。

vue-cli: 用户生成Vue工程模板

开始安装:

1.nodejs由于我已经安装好了,跳过

Vue.js development environment setup

2.webpack

npm install webpack -g
Copy after login

Vue.js development environment setup

3.安装vue脚手架

npm install vue-cli -g
Copy after login

Vue.js development environment setup

测试:

在硬盘上找一个文件夹放工程用的,在终端中进入该目录

cd 目录路径
Copy after login

根据模板创建项目

vue init webpack-simple 工程名字<工程名字不能用中文>或者创建 vue1.0 的项目vue init webpack-simple#1.0 工程名字<工程名字不能用中文>
Copy after login

Vue.js development environment setup

工程目录如图所示:

Vue.js development environment setup

安装项目依赖:

安装 vue 路由模块vue-router和网络请求模块vue-resource

进入该项目执行

npm install vue-router vue-resource --save
Copy after login

Vue.js development environment setup

启动项目

npm run dev
Copy after login
Copy after login

运行就报错

&#39;NODE_ENV&#39; 不是内部或外部命令,也不是可运行的程序或批处理文件。npm ERR!

Copy after login

Vue.js development environment setup

这是windows不支持NODE_ENV=development的设置方式

解决方法:

●安装across-env: npm install cross-env --save-dev

●在NODE_ENV=xxxxxxx前面添加cross-env就可以了。

运行还是报错:

找不到webpack这个模块

module.js:457 throw err; ^Error: Cannot find module &#39;webpack&#39; at Function.Module._resolveFilename (module.js:455:15) at Function.Module._load (module.js:403:25) at Module.require (module.js:483:17) at require (internal/module.js:20:19) at Object.<anonymous> (D:\vue_work\fendo\webpack.config.js:2:15) at Module._compile (module.js:556:32) at Object.Module._extensions..js (module.js:565:10) at Module.load (module.js:473:32) at tryModuleLoad (module.js:432:12) at Function.Module._load (module.js:424:3)
Copy after login

Vue.js development environment setup

安装该模块:

安装该模块:

ccnpm install 模块名 --save-dev(关于环境的,表现为npm run dev 启动不了)cnpm install 模块名 --save(关于项目的,比如main.js,表现为npm run dev 成功之后控制台报错)比如escape-string-regexp、strip-ansi、has-ansi、is-finite、emojis-list
Copy after login

安装好后运行又报这个模块的错:

Error: Cannot find module &#39;bl&#39; at Function.Module._resolveFilename (module.js:455:15) at Function.Module._load (module.js:403:25) at Module.require (module.js:483:17) at require (internal/module.js:20:19) at Object.<anonymous> (C:\Users\fendo\AppData\Roaming\npm\node_modules\npm\node_modules\request\request.js:9:10) at Module._compile (module.js:556:32) at Object.Module._extensions..js (module.js:565:10) at Module.load (module.js:473:32) at tryModuleLoad (module.js:432:12) at Function.Module._load (module.js:424:3)
Copy after login

接着继续安装

cnpm install bl --save-dev
Copy after login

再运行:

npm run dev
Copy after login
Copy after login

The difference between componentization and modularization: Modularization is divided from the perspective of code logic; it facilitates code layered development and ensures that the functions of each functional module are consistent. Componentization is planning from the perspective of UI interface; componentization of the front end facilitates the reuse of UI components.

Since the release of Vue3, the word composition API has entered the field of vision of students who write Vue. I believe everyone has always heard how much better the composition API is than the previous options API. Now, due to the release of the @vue/composition-api plug-in, Vue2 Students can also get on the bus. Next, we will mainly use responsive ref and reactive to conduct an in-depth analysis of how this plug-in achieves this.
