I am getting errors while trying to save sessions on MongoDB
const MongoStore = require('connect-mongo');
const connectDB = require('./config/db');
const { connection } = require('mongoose');
app.use(
session({
secret: 'some secret',
resave: false,
saveUninitialized: true,
store: MongoStore.create({
client: connection,
}),
cookie: {
maxAge: 1000 * 60 * 60 * 24,
},
})
);
Error:
C:\Users\Tezz\Desktop\Express\PassportJsAuth\express-session-authenticator\node_modules\connect-mongo\build\main\lib\MongoStore.js:126
.db(options.dbName)
^
TypeError: con.db is not a function
at C:\Users\Tezz\Desktop\Express\PassportJsAuth\express-session-authenticator\node_modules\connect-mongo\build\main\lib\MongoStore.js:126:18
Here is the Solution:
const express = require('express');
const session = require('express-session');
require('dotenv').config();
const MongoStore = require('connect-mongo');
const connectDB = require('./config/db');
const PORT = process.env.PORT || 3001;
const MONGO_URI = process.env.MONGODB;
const app = express();
//connectDB should return the client conn.connection.getClient();
const client = connectDB().then((mClient) => {
app.listen(PORT, () => console.log('Server running...');
return mClient;
}).catch(err => console.log(err));
app.use(express.json());
app.use(express.urlencoded({ extended: true}));
app.use(
session({
secret: 'some-secret',
resave: false,
saveUninitialized: true,
store: MongoStore.create({
client,
}),
})
);
app.get('/', (req, res, next) => {
res.send('<h1>Hello World (sessions)</h1>');
});
```
I am trying to save data to my database MongoDb atlas by making a post request but getting this error "Operation mytables.insertOne() buffering timed out after 10000ms". I have tried many solution available on internet but none of them is working for me (
Server.js
const express = require('express');
const app = express();
const mongoose = require('mongoose');
const dotenv = require('dotenv');
const routesUrls = require('./routes/routes');
const cors = require('cors');
dotenv.config();
mongoose.connect(process.env.DATABASE_ACCESS,{ useNewUrlParser: true, useUnifiedTopology: true, useCreateIndex: true},()=>console.log("Datbase Connected"));
app.use(express.json());
app.use(cors());
app.use('/app',routesUrls);
app.listen(3000,()=>{
console.log("server.js");

Any help will be appreciated
https://mongoosejs.com/docs/connections.html#buffering
Mongoose lets you start using your models immediately, without waiting for mongoose to establish a connection to MongoDB.
Try
Start your application only after DB is connected.
mongoose.connect(process.env.DATABASE_ACCESS,{ useNewUrlParser: true, useUnifiedTopology: true, useCreateIndex: true},(err) => {
console.log(err);
app.listen(3000,()=> {
console.log("server.js");
})
});
In my API is the current user (I have logged in with passport) but when I make an Axios get request the data field is empty. I absolutely don't know what to do :(
<script>
import axios from "axios"
export default {
name: 'Home',
components: {
},
data: function() {
return {
user: axios.get('http://127.0.0.1:3000/api/').then(response => this.user = response)
}
},
methods: {
}
}
</script>
Here is the output:
Here is my API:
Edit: Here is my Backend File:
const express = require('express');
const bodyParser = require('body-parser')
const mongoose = require('mongoose')
const cors = require('cors')
const passport = require('passport')
let LocalStrategy = require('passport-local').Strategy;
const session = require('express-session')
var app = express();
app.use(bodyParser.json())
app.use(bodyParser.urlencoded({
extended: true
}));
app.use(express.json());
app.use(express.urlencoded({ extended: true }));
const port = 3000
app.use(cors({
methods:['GET','POST'],
credentials: true
}))
app.use(express.static('public'))
//Passport setup
app.use(session({
secret: 'test',
resave: false,
saveUninitialized: false,
secure: true
}))
app.use(passport.initialize());
app.use(passport.session());
passport.serializeUser(function(user, done) {
done(null, user);
});
passport.deserializeUser(function(user, done) {
done(null, user);
});
const apiRoutes = require('./apiRoutes')
app.use(cors())
app.use('/api', apiRoutes)
// connect to database
mongoose.connect('mongodb+srv://#cluster0.dhsiv.mongodb.net/test?retryWrites=true&w=majority',
{useNewUrlParser: true, useUnifiedTopology: true}, () => {
console.log('Erfolgreich connected')
})
app.listen(port, () => {
console.log('server is running on port '+port)
})
module.exports;
I hope someone can help me. Thanks a lot guys :)
i have also change my data and run the axios get in mounted but it doesnt change anything.
