Ionic using vue and capacitor to create camera app and save image to folder

please, how to create a camera application then save and upload it to a folder on localhost or hosting using Vue ionic? ,
I’m still not very familiar with the use of fileSystem in the documentation capacitorJs. It will be very easy if there is an example source code. I’m just using Vue js without typescript

have you tried looking at the official documentation? https://github.com/ionic-team/tutorial-photo-gallery-vue
