I'm new in MongoDB and GraphQL. I tried to study this tutorial https://www.djamware.com/post/5c75d68880aca754f7a9d1ed/node-express-angular-7-graphql-and-mongodb-crud-web-app and get stuck in 2nd step (MongoDB connection). Here's the error : Error1 Error2
This is my app.js :
var createError = require('http-errors');
var express = require('express');
var path = require('path');
var cookieParser = require('cookie-parser');
var logger = require('morgan');
var indexRouter = require('./routes/index');
var usersRouter = require('./routes/users');
var app = express();
//declare the Mongoose module
var mongoose = require('mongoose');
//Create a connection to the MongoDB server
mongoose.connect('mongodb://localhost/GraphQL/node-graphql', { promiseLibrary: require('bluebird'), useNewUrlParser: true })
.then(() => console.log('connection successful'))
.catch((err) => console.error(err));
// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');
app.use(logger('dev'));
app.use(express.json());
app.use(express.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));
app.use('/', indexRouter);
app.use('/users', usersRouter);
// catch 404 and forward to error handler
app.use(function(req, res, next) {
next(createError(404));
});
// error handler
app.use(function(err, req, res, next) {
// set locals, only providing error in development
res.locals.message = err.message;
res.locals.error = req.app.get('env') === 'development' ? err : {};
// render the error page
res.status(err.status || 500);
res.render('error');
});
module.exports = app;
How to fix that error? I'm really stuck
