概要：安装Mongodb，数据库创建，创建数据库集合增加数据，接入Nuxt安装工具库、配置数据库

安装Mongodb与语法使用

详情参考【菜鸟】Mongodb

创建数据

1、链接数据库

>mongosh --host localhost --port 27017 -u "testuser" -p "passwrord123" --authenticationDatabase "runoob"
Current Mongosh Log ID: 673702de4df19e91d40d818f
Connecting to:          mongodb://<credentials>@localhost:27017/?directConnection=true&serverSelectionTimeoutMS=2000&authSource=runoob&appName=mongosh+2.3.3
Using MongoDB:          8.0.3
Using Mongosh:          2.3.3

2、创建数据库

test> use runoob
switched to db runoob

3、创建集合增加数据

runoob> db.createCollection("myNewCollection")
{ ok: 1 }
runoob> show tables
myNewCollection
runoob> db.myCollection.insertOne({name:"alice",age:30})
{
  acknowledged: true,
  insertedId: ObjectId('673703dd4df19e91d40d8190')
}

接入安装Nuxt

安装工具库、配置

npm i -D mongodb

import { MongoClient } from 'mongodb'
// mongodb://[username:password@]host1[:port1][,...hostN[:portN]][/[defaultauthdb][?options]]
const dbConfig = {
  ip: '127.0.0.1',   //IP地址
  port: '27017',　// 端口 默认是27017
  dbname: 'runoob', // 数据库名称
  name: 'testuser', // 数据库用户名
  password: 'passwrord123' // 数据库密码
}
const url = `mongodb://${dbConfig.name}:${dbConfig.password}@${dbConfig.ip}:${dbConfig.port}/${dbConfig.dbname}`;
const mongodb = MongoClient.connect(url);
export default mongodb;

import mongodb from '../connectSQL'
export default defineEventHandler(async (event) => {
  const dbtable = (await mongodb).db('runoob').collection('myNewCollection')
  // console.log('dbtable==>', dbtable)
  // 查询runoob数据库下的myNewCollection合集
  let content = await dbtable.find().toArray()
  return {
    hello: 'world',
    content
  }
})

<script lang="ts" setup>
  const res = await useFetch('/api/test')
  console.log('res====>', res)
</script>
