The traditional way to do this is to run npm i ( i for “install”).

Once that’s done, we need to install some packages from our Node.js project’s newly populated dependency list in package.json. So to be current and use Pug straightaway-plus, avoid deprecation warnings-we tack on -view=pug, a command-line option for the express-generator script being run by npx.

As of this writing, the generator makes an Express/Node.js project that, by default, still pulls in a template engine called Jade, even though the Jade project renamed itself to “Pug” from version 2.0 onward. We’re using it to run Express’ application skeleton generator. Note: Here, npx is a handy tool that comes with npm, the Node.js package manager that ships with Node.js. It may already work on a Mac.Īssuming a modern version of Node.js is installed, and a command prompt is open in a new directory that will serve as the project root, we’re ready to get started with Express: npx express-generator -view=pug New Gizmos from Old: Repurposing Phones as Remote Controls Using a Node.js Back Endįirst off, note that this Node.js project is currently specific to Linux-developed and tested on Linux Mint 19 and Linux Mint 19.3, in particular-but support for other platforms could certainly be added. Hours later, it was beyond clear that it would be much easier to start from scratch-this author's own advice against reinventing the wheel notwithstanding. An obstinate approach and Node.js back-end compatibility were no match for endless deprecations and impossible dependency loops among old versions of Grunt, Bower, and dozens of other components.
nvm makes it easy to install older versions of Node.js, and even if a few dependencies needed upgrading, Node.js had a great reputation for being backward-compatible. These issues have been around a long time and were even the motivation for a similar project from 2014 found on GitHub. But even if this aspect is appropriately limited, the nature of a remote control app means that users still have to trust that app developers aren't abusing their privileges on the desktop end of the solution by including spyware or other malware. Like so many apps to be found on any mobile platform, they often come with the requirement of users granting far more permissions than the app needs for what it purports to do. (The app store was officially shut down in late 2019.)

For those trying to repurpose an older phone, this might simply not be an option anymore, as is the case with the Windows Phone 8.1 device I wanted to use.But there are two major reasons this may not be desirable: Readers may wonder, "Why get into coding a Node.js back end?" (Aside from the learning opportunity, of course.) "Isn't there already an app for that?" If that sounds daunting, the complete Node.js project will be presented at the end readers need only learn as much as they’re interested in learning, and there will be a fair number of gentler explanations of some basics along the way that more experienced readers can skip. It’s also a Node.js back-end tutorial: a chance to learn the basics of back-end JavaScript using the Express framework and the Pug (formerly Jade) template engine. That’s where this project comes in: The opportunity to transform any smartphone-even an old one that’s otherwise useless for lack of updates-into a handy remote for the next Netflix/YouTube/Amazon Prime Video/etc. While exercise is especially important right now, sometimes, there’s nostalgia for the luxury of a good, old-fashioned remote control when the laptop is beyond easy reach. Many of us are consuming more video content than ever before. The COVID-19 lockdown has many of us stuck at home, perhaps hoping that mere cabin fever is the worst kind of fever we’ll experience.
