Image resizer. Just clone the project, npm i, and then to run the process: npm start OR npx electronmon . This last will watch for life changes in case you want to modify the app. Go the 1st branch to have a look at the files.
The main learning of this demo is to discover the core functionalities of electronjs but as a matter of fact it really helped me refresh a lot of concepts and core modules of nodejs, like the file system. To wrap the app into an executable, one needs to use something like electron package. I might do that any time in the future.
