node.js 笔记

正则多字符匹配

  var re = /最大|绝对|最低|第一/gi;
                var resname = name.replace(re, function (sMatch) {
                    return sMatch.replace(/./g, "");
                });

fs写入读取

const loadData = (path: any) => {
    try {
        return fs.readFileSync(path, 'utf8')
    } catch (err) {
        console.error(err)
        return false
    }
}


const storeData = (data: any[], path: string) => {
    try {
        fs.writeFileSync(path, JSON.stringify(data))
    } catch (err) {
        console.error(err)
    }
}

const WriteError = (data: string, path: string) => {
    try {
        fs.appendFileSync(path, data)
    } catch (err) {
        console.error(err)
    }
}
