I'm trying to connect to a MongoDB Atlas database with typeORM in an express project but I'm getting a 'Unescaped slash in userinfo section' error. My password doesn't have any special characters that need to be encoded so I don't know what's going on.
import { DataSource } from "typeorm"
export const AppDataSource = new DataSource({
type: "mongodb",
host: "mongodb+srv://username:password#database.cluster.mongodb.net/?retryWrites=true&w=majority",
useNewUrlParser: true,
synchronize: true,
useUnifiedTopology: true,
logging: true,
ssl: true,
entities: [
"src/entity/*.ts"
],
subscribers: [],
migrations: [],
})
"use strict";
import express from "express";
import cors from 'cors';
import "reflect-metadata";
import { AppDataSource } from "./data-source";
AppDataSource.initialize().then(() => {
const app = express();
app.use(cors({
origin: ['http://localhost:3000'],
credentials: true // this will allow cookies to be sent accross domains
}));
app.listen(8080, () => {
console.log("Server is running on port 8080");
})
})
the error I'm getting :
return callback(new MongoParseError('Unescaped slash in userinfo section'));

Just replace host params to url in DataSource options
export const AppDataSource = new DataSource({
type: "mongodb",
url: "mongodb+srv://username:password#database.cluster.mongodb.net/?retryWrites=true&w=majority",
useNewUrlParser: true,
synchronize: true,
useUnifiedTopology: true,
logging: true,
ssl: true,
entities: [
"src/entity/*.ts"
],
subscribers: [],
migrations: [],
})
const uri = mongodb+srv://${process.env.DB_USER}:${process.env.DB_PASS}#cluster0.twqkk.mongodb.net/?retryWrites=true&w=majority;
const client = new MongoClient(uri, { useNewUrlParser: true, useUnifiedTopology: true, serverApi: ServerApiVersion.v1 });
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 (

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");
})
});
I am new in mongodb and currently following this article: https://medium.com/#beaucarnes/learn-the-mern-stack-by-building-an-exercise-tracker-mern-tutorial-59c13c1237a1
I am using mongoDB atlas as a course suggested and also whitelist my IP in it as many answers suggested.

currently its showing Error in console:

There was an error connecting to http://localhost:5000/users/add.
