准备尝试用vue制做一个手机端的可视化应用css

全局安装vue命令html

cnpm install -g @vue/cli

建立项目vue

进入项目存放目录新建项目node

vue create [project name]
cd [project name]

安装插件web

这里我安装了一个代码校验、以及router、vuexvuex

vue add @vue/eslint
vue add router
vue add vuex

全局CLI配置npm

在以往的版本中都会有个config文件做为全局配置，可是当前的版本须要本身添加  vue.config.js  ，只要在package.json同级目录下（即根目录）建立json

const path = require("path");

function resolve(dir) {
  return path.join(__dirname, "./", dir);
}

module.exports = {
  chainWebpack: config => {
    // 为src下文件配别名，不使用相对路径
    config.resolve.alias
      .set("@", resolve("src"))
      .set("assets", resolve("src/assets"))
      .set("components", resolve("src/components"))
      .set("views", resolve("src/views"))
      .set("icons", resolve("src/icons"))
      .set("router", resolve("src/router"))
      .set("utils", resolve("src/utils"))
      .set("style", resolve("src/style"));

    /** 设置处理svg的router，使svg可直接用名称调用，无需路径 */
    // svg rule loader
    const svgRule = config.module.rule("svg"); // 找到svg-loader
    svgRule.uses.clear(); // 清除已有的loader, 若是不这样作会添加在此loader以后
    svgRule.exclude.add(/node_modules/); // 正则匹配排除node_modules目录
    svgRule // 添加svg新的loader处理
      .test(/\.svg$/)
      .use("svg-sprite-loader")
      .loader("svg-sprite-loader")
      .options({
        symbolId: "icon-[name]"
      });
  },
  /** 开发环境代理 */
  devServer: {
    open: true,
    proxy: {
      "/api": {
        target: "http://localhost:3000",
        ws: true,
        changeOrigin: true,
        pathRequires: {
          "^/api": ""
        }
      }
    }
  }
};

接下来是一些移动端的配置canvas

禁止页面放大缩小api

禁止移动端经过手指放大缩小页面

页面位置 public/index.html  

<meta name="viewport" content="width=device-width,initial-scale=1.0,minimum-scale=1.0,maximum-scale=1.0,er-scalable=no">

FastClick

为避免浏览器兼容问题引发的点击问题（部分浏览器对点击事件有300毫秒的延迟响应机制）

import fastClick from "fastclick"

if ("addEventListener" in document && "ontouchstart" in window) {
  FastClick.prototype.focus = function(targetElement) {
    targetElement.focus();
  };
  document.addEventListener(
    "DOMContentLoaded",
    function() {
      FastClick.attach(document.body);
    },
    false
  );
}

Reset.css
