Using NPM

The NPM setup allows you to install and run HOPRd as a Nodejs application, ensuring your experience is a close as to the developer’s have when developing HOPRd and the HOPR Core protocol. Nodejs might require further software installation, but is able to be run in less hardware demanding machines, while taking considerable less space in comparison to Docker (i.e. 50mb).

Installing NPM

In order to get NPM on your machine, you will need to install Nodejs, our recommended way of doing this is to install nvm / nvm-windows, a Nodejs version manager. This ensures we can install and uninstall as many versions of Nodejs as needed. Furthermore, it will help you installing any additional requirements (if any) for running Nodejs.

Please bear in mind you might need to restart your terminal after running these commands.

Installing Nodejs

After you have downloaded and setup nvm in your machine (run nvm ls to ensure everything is in place), now you need to install a specific version of Nodejs before running HOPRd.

At the time of writing, HOPRd runs on Nodejs v14. Specifically, HOPRd has been developed and tested in v14, so in case you run on any issues with HOPRd, try switch to v14 to see if those issues disappear.

To install Nodejs with nvm, run the following

$ nvm install v14
$ nvm use v14

If everything was done properly, you can run node --version to see your current node version, alongside running basic commands as shown when running simply node in your terminal.

Attention

MacOS M1 users will need to follow an extra set of instructions from NVM to allow them to use nodejs 14.
