I’ve received questions from readers of my Beginner’s Guide to Installing Node.js on a Raspberry Pi wanting to know how to upgrade to more recent versions of Node.js on the Raspberry Pi. The steps are quite easy and can be adapted to other Debian variants as well including Ubuntu. I’m assuming you followed the steps in my Beginners’ Guide, especially under the “Install Node.js” section where we update the Raspbian/Debian package repository to include the Node.js binaries provided by NodeSource. Let’s get started! Continue reading
This article has been updated to cover the installation of the latest version of Node at the time of this writing which is Node 9.x.
In this installment of our LTM (Learning through Making) series of Node.js tutorials, we’re going to get Node up and running on a Raspberry Pi 3 or Pi 2. With the Raspberry Pi 3, you won’t need to buy a separate USB Wi-Fi adapter. I’m focusing on the Raspberry Pi 3/Pi 2 rather than older versions such as the Raspberry Pi B+ since these are the latest models at the time of this writing. The Raspberry Pi 3, for example, sports a 1.2 GHz quad-core ARMv8 chip with 1 GB of RAM versus the Raspberry Pi 1 Model B+’s 700 MHz single-core ARMv6 chip with 512 MB RAM.
The instructions provided here are for installing Node.js on a Pi 3 (ARMv8) or Pi 2 (ARMv7) rather than other models based on the ARMv6 chip such as the Raspberry Pi 1 Model B, Raspberry Pi Model B+ or the Raspberry Pi Zero. A majority of this installation guide should still prove useful for other Raspberry Pi systems besides the Pi 3 and Pi 2; however, the final steps focused on the installation of Node.js will not work for these systems based on the older ARMv6 architecture.
This tutorial is useful for anyone wishing to successfully install a Raspberry Pi 3/Pi 2 system, even if they are not interested in Node.js since the Node.js installation happens in the final steps of the tutorial. But, why would you not want to install Node.js? 🙂 Let’s get started! Continue reading
Our friends at NodeSource host a package repository that makes installing and maintaining Node on the Raspberry Pi easy. Keep reading to learn how to get started. Continue reading
We all want to be in the loop and notified when certain events occur within our Node.js programs. For example, email notifications can be very important for creating situational awareness with IoT systems we develop that interact with our physical world. Email communication can be used to deliver messages to our inboxes as well as to deliver text messages in order to enable us to take more immediate action.
In today’s tutorial, we’ll walk through the steps of using the amazing Nodemailer package which has become the de facto standard for sending email messages in the Node.js world. Let’s get started so we can start seeing our own custom messages flow to our inbox! Continue reading
