Server.js
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 | const express = require('express') const sever = express() const port = 4000 var routes = require('./routes/routes'); var mongoose = require('mongoose'); mongoose.set('strictQuery', true); mongoose.connect("mongodb://127.0.0.1:27017/dbschool",{useNewUrlParser: true, useUnifiedTopology: true },function checkDb(error) { if(error) { console.log(error); } else { console.log("successfully Connected to DB"); } }); sever.use(express.json()); sever.use(routes); sever.listen(port, () => { console.log(`Express port successfully ${port}`) }) |
routes.js
1 2 3 4 5 6 7 8 | var express = require('express'); var userController = require('../src/employee/userController'); const router = express.Router(); router.route('/user/findOne/:name').get(userController.findOneUserController); module.exports = router; |
userController.js
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | var userService = require('./userService'); var findOneUserController = async (req, res) => { console.log(req.params.name ); var result = await userService.findOneUserDBService(req.params.name ); if (result) { res.send({ "status": true, "data": result} ); } else { res.send({ "status": false, "data": "User not found" }); } } module.exports = { findOneUserController}; |
userModel.js
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 | var mongoose = require('mongoose'); var Schema = mongoose.Schema; var userSchema = new Schema({ name: { type: String, required: true }, address: { type: String, required: true }, phone: { type: String, required: true } }); module.exports = mongoose.model('employees', userSchema); |
userService.js
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 | var userModel = require('./userModel'); module.exports.findOneUserDBService = (userDetais) => { return new Promise(function myFn(resolve, reject) { userModel.findOne({name:userDetais}, function returnData(error, result) { if(error) { reject(false); } else { resolve(result); } }); }); } |
