how to linux hosting server nodejs and npm installing

If you want to work with any language related to javascirpt, the first problem you have to read is to install node js on the server.

Especially shared hosting is a major problem. Of course, some share hosting now has Node Joss installed by default. However, many times it does not work. The reason is that maybe your development version is more updated than the version given there. So here's how to install node js in Linux: - To install shared hosting node js and npm, the server must have root access or terminal access. This post will show with terminal access.

1. Login to the shared hosting panel and open the terminal.

Now type node -v or node --version

If it shows you v16.1.0 or any version of node js, then you have node js and npm installed on your server.

If you don't show anything like that, you will understand that node js and npm are not installed.

  curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.38.0/install.sh | bash 

Copy and enter the terminal. This time

=> Close and reopen your terminal to start using nvm or run the following to use it now:

export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm
