Deploy node.js express micro service to linux server and go live in 10 minutes

I have described the deployment in steps for a new server which does not have any software installed, but if you have those software installed, just skip those steps and move on to next.

I am using aws Amazon Linux 2023 for demo, but the deployment will work for any linux server.

Installations

1. download nvm. NVM is a node version manager and in order to install Node and npm, first nvm is to be installed using following commands

/curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.11/install.sh | bash

. ~/.nvm/nvm.sh

2. next install node and npm, the version should be the version as your application, if version is not given, the latest version will get installed

nvm install <<version>>

3. for getting the code from any of your git repositories, install git package, skip this step if the code can be copied using any other way like ftp, winscp etc.

sudo dnf install git

4. install pm2 server, pm2 is a package which ensures api running even system crashes, application crashes and such, it automatically restarts the app again

npm install -g pm2

Deployment

5. copy the code to server directory wherever you want

git clone <<github or any other git repo url>>

6. run the app using pm2

pm2 start app.js

Ensure that the port eg. 3000 on which the node js application is listening is open on the server.

Now you can check the api end points using postman or browser. Replace localhost with ip of the server in all your end points.

Now starting a node js express server project is easy. Just provide the name of the project and hit Create Project. A zip file is downloaded, just unzip the file and run npm install on root of the project. and the your project with correct folders and paths is ready. Just npm start and http://localhost:3510 will get you Namaste World!!.
