快速自动生成vue路由，vue-cli项目中src目录下的views中的路由

 对于小型点的项目可以这样玩。

代码实现原理就是利用fs和path模块，递归views目录生成vue路由。

//安装 fs和path模块
let fs = require('fs');
const path = require('path');
let root = path.resolve(__dirname, 'src/views')
console.log('开始配置>>>>>>>>>>>>>>>>>>\n')
// 读取文件信息，并生成路由
function readFileInfo(pathName, dirName) {
    let routes = [];
    let dirDetails = fs.readdirSync(pathName);
    let exclude = null;//排除的文件，不生成路由
    let excludeDir = null;//排除的目录，不遍历目录
    let childList = null;//子路由
    if (dirDetails.length == 0) {
        return []
    }
    if (dirDetails.includes('config.json')) {
        // 读取json数据
        const json = JSON.parse(fs.readFileSync(path.resolve(pathName, 'config.json')))
        // 判断是否有exclude属性
        const excludeList = json.exclude || [];
        const child = json.children || [];
        const excludeDirList = json.excludeDir || [];
        if (child && child.length > 0) {
            // 有配置子路由项
            childList = ObjArrDuplicate(child).map((element) => {
                if (!element.parent) {
                    throw new Error('parent属性不能为空 ' + path.resolve(pathName, 'config.json'))
                }
                const parent = suffixVue([], element.parent)
                const list = ArrayDuplicate(suffixVue(element.list));
                ArrayDuplicate(list)
                // 判断文件是否存在
                checkFileExis(list, pathName, 'list属性');
                checkFileExis([parent], pathName, 'parent属性');
                return {
                    parent,
                    list
                }
            });
        }
        // 排除的vue文件
        if (excludeList && excludeList.length > 0) {
            exclude = ArrayDuplicate(suffixVue(excludeList));
            checkFileExis(exclude, pathName, 'exclude属性');
        }
        // 判断排除目录
        if (excludeDirList && excludeDirList.length > 0) {
            excludeDir = ArrayDuplicate(excludeDirList);
            excludeDir.forEach((dir) => {
                if (!dirDetails.includes(dir)) {
                    throw new Error('没有找到目录 ' + path.resolve(pathName, dir) + '，请正确配置exclude属性值')
                }
            })
        }

    }
    if (exclude && exclude.length != 0) {
        // 打印
        exclude.forEach((item) => {
            console.log('排除生成的路由文件>>>>>>>>>>>>>>>>>>\n', [path.resolve(pathName, item)], '\n')
        })
    }
    // 遍历文件生成对应的路由规则
    dirDetails.forEach((item) => {
        let is = fs.statSync(path.resolve(pathName, item))
        if (is.isFile()) {
            if (exclude && exclude.includes(item)) {

            if (suffix == '.vue') {
                const routeName = dirName.split('/').join('-');
