Github stars and forks on matrix display
An easy to use application which displays the number of forks and stars of your Github repository on a matrix display.
- Installed npm and nodejs
- Installed Web of Things matrix display
- Windows (with WSL 2), MacOS or Linux
Web of Things is all about interoperability. In another tutorial we flashed an app on an ESP32 with connected matrix LED diplay. This app exposes a Web of Things Thing Description and HTTP REST API. In this tutorial we are going to use this device in order to display the number of stars and forks on it. We are going to use the node-wot library which implements the Web of Things Scripting API. This reduces the amount of code we have to write in order to understand the REST API.
Clone the app
git clone https://github.com/Citrullin/node-wot-github.git cd node-wot-github
Change the IP address
Open the file
src/index.ts in an editor. Replace
192.168.178.28 with the IP address of your ESP32. Save the file.
Change the repository name
In order to show the number of stars and forks of your favourite repository, we have to change the name of the repository.
There is a variable called
repoName with the value
Change the value accordingly. The name of the repository always has to include the organisation name or username as well.
In order to install all dependencies, you have to run
Run the application
You can start the application with
npm run start
When everything runs as expected you should see a log in the terminal. The application should call the REST API of the matrix display in order to show the number of stars and forks. After executing the command, it may take a moment before you see the first text on the matrix display.
