How to Build a Photo Tweeting Twitter Bot With Raspberry Pi and Node.js

Posted on

Looking for a way to make Twitter more useful, if only for other people? One way is to create an automated Twitter bot that tweets images with useful descriptions. You could do this manually… or you could build it with Node.js and host it on a Raspberry Pi. Read on to find out how.

Why Build a Twitter Bot?

If you’ve ever been on Twitter and seen accounts that post photos, or facts, or cartoons, etc., then it’s overwhelmingly likely that these are automated. It’s a great way to build an audience of people interested in the same topic.

But there is another reason, beyond retweets and follows. Building a Twitter bot will teach you some useful programming skills. We’ve previously looked at how to build a basic Twitter bot with Python (also on a Raspberry Pi), but this time we’re taking a different approach. computer science computer science computer science computer science computer science computer science

In this project, we’re going to use Node.js to build a photo-tweeting bot on a Raspberry Pi. The photos will be photos from the First World War, accompanied by a short sentence and attribution). This information will be stored in an array, a basic database. computer science computer science computer science computer science computer science computer science

Get Started: Build Your Database

If you want to build a photo tweeting bot, you’ll need to start by collecting the images you want to share. These should either be your own images, or ones you’ve acquired under a Creative Commons or some other open source license. computer science computer science computer science computer science computer science computer science

You should also keep note of attribution and other information that you want to go with the images. We’ll come back to this information later, once the bot is up and running.

Install Node.js on Raspbian

Begin by installing Node.js. You should already have a Raspberry Pi up and running, with Raspbian installed. For this project, we recommend a Raspberry Pi 2 or later; the project was tested on the Raspberry Pi 3 B+.

In the terminal (or via SSH), update the system package list, and upgrade to the latest version:

sudo apt-get update
sudo apt-get dist-upgrade

Follow the on-screen prompt, and wait while your Pi updates. Once you’re done, reboot with

sudo reboot

When you’re done, use curl to download Node.js:

curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -

Next, install it with

sudo apt-get install -y nodejs

When all is done, run a check to ensure the software was installed correctly. The easiest is to check for the version number:

node -v

The response should be something like v8.11.3 (or higher). If you see something like that, you can be confident that Node.js is ready to use.
