Since this a Node.js application, Node.js is obviously required to run it. I recommend to use the LTS version of Node.js, which is currently version 18. This is also the version under which this application has been developed and tested. Therefore, using an older version of Node.js may work, but it is not recommended.
If you are on Windows, just download the MSI installer package and install it.
If your Linux distribution does not provide a recent Node.js version (at least version 18 is recommended), you can add an (unofficial) Node.js package repository to your system.
On Debian-based systems create the file /etc/apt/sources.list.d/nodejs.list and give it the following contents:
# Node.js 18.x for Debian 11 (codename bullseye)
deb https://deb.nodesource.com/node_18.x bullseye main
deb-src https://deb.nodesource.com/node_18.x bullseye main
After that do
apt-get update && apt-get upgrade
to update the APT package lists. To install Node.js 18, type
apt-get install nodejs
That's it.
On a RedHat-based system (e.g. CentOS) make sure curl is installed and then type
curl -sL https://rpm.nodesource.com/setup_18.x | bash -
to download and execute a bash script that will take care of the installation. You might want to check the script code before doing that, though.
The application requires a package for jsdom. To install that, type
npm install
in the directory export-server/. You only need to do this once. The packages
are then cached in the node_modules/ directory for future use.
