Setting Up Node.js On Raspberry Pi

There are several ways that you can set up Node.js on a Raspberry Pi when running Raspbian/Rapberry Pi OS. Depending on your needs, the version of the RPi that you're using, and how you like to manage installs, you have a lot of options.

A brief aside: alternative runtimes

Node.js was an early entrant to the Javascript runtime and I think it's still the most widely used. But it's not the only runtime out there these days. Some of the alternatives might be better choices for your Raspberry Pi setup.

The two other Javascript runtimes I've used are deno and bun. Both are newer than Node.js and have incorporated a modern features nicely, like built-in support for Typescript. They also have a more compact install, since they bundle everything into a single CLI executable.

Connect your devices to a pi that has been configured like below.

Pi Setup

Download raspbian etc, go through normal setup.

Setup networking

This will let you find your pi locally using it's name, e.g. ping davepi.local

sudo apt-get update

sudo apt-get install avahi-daemon

hub.me ...ou a história do meu amigo Clark Kent

Eu amo o Github, sério, eu amo mesmo. E não sou só eu, meu amigo super desenvolvedor Clark Kent ama também.

Algumas semanas atrás, ele decidiu criar um novo projeto no Github chamado Krypton.

Esse projeto era incrível e à medida que o tempo passava mais e mais pessoas começaram a acompanhar e forkar o projeto. Irado!
