You need database driver to connect to any database like mysql,mongodb, neo4j etc. I haven't used mysql but quick search on www.npmjs.org reveals mysql https://npmjs.org/package/mysql as first options so go with it for start. For mongodb the most popular choices are mongodb https://npmjs.org/package/mongodb if you prefer to work with documents yourself or choose mongoose https://npmjs.org/package/mongoose if your prefer ORM. So just add them in your package.json dependencies and do npm install

你需要数据库驱动程序来连接任何数据库，比如mysql、mongodb、neo4j等等。对于mongodb，最受欢迎的选择是mongodb https://npmjs.org/package/mongodb，如果你喜欢使用ORM，你可以选择mongoose https://npmjs.org/package/mongodb。所以只要把它们添加到你的包中。json依赖项并执行npm安装

 {
   "dependencies" : {
     "mongodb"   :  "*",
     "mysql" :  "*",
     "mongoose " :  "*"
    }
 }
