Starting a new project can be overwhelming, especially when dealing with the phonegap filechooser. I have managed to use it before but now I am at a loss on how to properly read the file and send its contents to the server afterwards.

If you have a task that involves transferring files, consider utilizing the File Transfer and File native plugins.
Here is an excerpt from the official documentation:
ionic cordova plugin add cordova-plugin-file-transfer
npm install --save @ionic-native/file-transfer
ionic cordova plugin add cordova-plugin-file
npm install --save @ionic-native/file
.ts
import { FileTransfer, FileUploadOptions, FileTransferObject } from '@ionic-native/file-transfer';
import { File } from '@ionic-native/file';
constructor(private transfer: FileTransfer, private file: File) { }
const fileTransfer: FileTransferObject = this.transfer.create();
// Upload a file:
fileTransfer.upload(..).then(..).catch(..);
// Download a file:
fileTransfer.download(..).then(..).catch(..);
// Abort active transfer:
fileTransfer.abort();
// Here is a complete example of uploading a file:
upload() {
let options: FileUploadOptions = {
fileKey: 'file',
fileName: 'name.jpg',
headers: {}
}
fileTransfer.upload('<file path>', '<api endpoint>', options)
.then((data) => {
// success
}, (err) => {
// error
})
}
// For downloading a file:
download() {
const url = 'http://www.example.com/file.pdf';
fileTransfer.download(url, this.file.dataDirectory + 'file.pdf').then((entry) => {
console.log('download complete: ' + entry.toURL());
}, (error) => {
// handle error
});
}
