Nodejs+mongodb+Authentication+express.js+Model–view–controller

What do you find here?

As nodejs doesn't give anything with the project, so we need to create everything manually. It is very difficult and time-consuming work. So here, i will show you,"How to directly you can get full setup" . Also Here, I give setup instructions of nodejs and MongoDB. Just follow the instructions.

Outline

• Nodejs installation
• Specific version nodejs installation
• nodejs setup
• MongoDB installation
• MongoDB compass installation (MongoDB software)
• MongoDB Setup
• Setup the demo project
• Checking Authentication
• Conclusion

Demo project content

• User Authentication system (Signup/sign in login)
• database system
• Controller,View,Model system with connection
• ejs template system
• database model system
• Public content connection setup

All these things will be found in this repository

Nodejs installation

sudo apt install nodejs
sudo apt install npm

These two commands in a terminal will download the latest version of nodejs.

Specific version nodejs installation

If You want any specific version of nodejs, then run these commands in terminal

sudo apt install build-essential checkinstall libssl-dev

curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.35.1/install.sh | bash

Restart the terminal

nvm --version

nvm install v13.14.0

sudo apt-get install npm

It will install v13.14.0. Also, you can check all available versions by calling this command.

nvm ls-remote

Nodejs setup

Ignore this section if you want my demo project as initial. If you don't want these setup. you can make your own project setup by calling,

npm init

MongoDB installation

curl -fsSL https://www.mongodb.org/static/pgp/server-4.4.asc | sudo apt-key add -

echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu bionic/mongodb-org/4.4 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-4.4.list

sudo apt update

sudo apt-get install -y mongodb-org

If you get any error in your system. You can ignore them or you can download the broken files manually.

MongoDB compass installation (MongoDB software)

Instead of using the terminal for checking the database, we will use MongoDB compass

wget https://downloads.mongodb.com/compass/mongodb-compass_1.24.1_amd64.deb
sudo dpkg -i mongodb-compass_1.24.1_amd64.deb

You can find a compass software in your software list now.

MongoDB Setup

sudo chown -R mongodb:mongodb /var/lib/mongodb
sudo chown mongodb:mongodb /tmp/mongodb-27017.sock
sudo service mongod start
sudo service mongod status

You can see Active message there . Whenever you get compass connection problem, you must start mongodb service again.

Setup the demo project

• Clone this demo project by

git clone https://github.com/Foysal87/nodejs-mongodb-demo.git

• open this project in VS code.
• Open a new terminal in vs code
• in terminal type

npm install

• Go to compass software on your pc. and connect it.
• Start the server by

node .

• If you don't get any Error. Go to your browser and type "localhost:3000"
• You can see the full setup
• As my project is so simple. You can easily create and change everything.

Checking Authentication

• Sign up with any username
• I didn't increase password and username length(you can change the size of the password). So you can put any length password.
• If you give the wrong value, you will get a validation error.
• login with username and password
• You will find the profile page.
• Check your database, you will find an entry.
• You also find the password encrypted

Conclusion

I create it because if anyone forgot the setup of nodejs, they can easily set up with this. Also, this demo project initializes everything.
