不要在节点 js 中连接到 mongodb

Question

在编写代码以通过项目中的节点连接 mongodb 时显示错误

我使用以下代码连接到 mongodb

var mongocilent=require('mongodb').mongocilent
var state = {db:null}
module.exports.connect=function(done){
var url ='mongodb://localhost:27017'
var dbname = "shopping" 
mongocilent.connect(url,(err,data)=>{
    if(err)return done(err)
        state.db=data.db(dbname)
        done()
    
})
module.exports.get=function(){
return state.db

}

但如果我启动服务器，它会显示：

npm start
> shopping-cart@0.0.0 start
> nodemon ./bin/www

[nodemon] 2.0.19
[nodemon] to restart at any time, enter `rs`
[nodemon] watching path(s): *.*
[nodemon] watching extensions: js,mjs,json
[nodemon] starting `node ./bin/www`
/home/shinoy/Desktop/binoy/shopping cart/config/connection.js:8
mongocilent.connect(url,(err,data)=>{

            ^

我尝试了与谷歌不同的解决方案，但它对我不起作用

您在要求 mongodb 的 MongoClient object 的第一行中拼写错误。 只需用这个替换第一行

const mongoclient = require("mongodb").MongoClient;
