备忘--node连接mongodb

# 1 启动mongodb数据库

# 2连接本地存储表

# 3 采用mongoose连接node

官网 

node项目存储数据得接口

const express = require(‘express‘);
const router = express.Router()

const mongoose = require(‘mongoose‘)
mongoose.connect(‘mongodb://localhost:27017/testdb‘, { useNewUrlParser: true })

const PositionModel = mongoose.model(‘positions‘, {
  positionName: String,
})
const position = new PositionModel({
  positionName: ‘就安大略‘
})
router.post(‘/save‘, (req, res) => {
  position.save().then((result) => {
    console.log(result)
    res.send(‘datas have saved mongodb‘)
  });
})

module.exports = router

# 4 再insomia中测试接口

# 5 在robo 3t可视化工具查看数据已经存入
