Я изучаю остальные API, но продолжаю получать следующую ошибку.Зачем?Я использую Node JS, Mongo DB и Express.Я новичок в этом.
Код:
var express = require('express');
var app = express();
var bodyParser = require('body-parser');
var mongoose = require('mongoose');
//connect to mongoose
mongoose.connect('mongodb://localost/bookstore');
var db = mongoose.connection;
app.get('/', function(req, res){
res.send('Please use /api for the API.');
});
app.listen(3000);
console.log('Running on port 3000...');
Ошибка:
(node:7908) DeprecationWarning: current URL string parser is deprecated, and wil
l be removed in a future version. To use the new parser, pass option { useNewUrl
Parser: true } to MongoClient.connect.
