Manage PDFs

This video shows you how to manage binary data (PDF files in this case) in an Apex Designer app:

Here is the upload behavior code snippet:

const file = this.fileUploadInput.nativeElement.files[0];
debug('file', file);

let reader: FileReader = new FileReader();

reader.onload = async () => {
	debug('reader.result', reader.result);

	const base64 = ('' + reader.result).substr(('data:' + file.type + ';base64,').length);
	debug('base64', base64);

	await this.pdfDocuments.add({
		fileName: file.name,
		size: file.size,
		base64Content: base64
	});

	this.fileUploadInput.value = null;

	await this.pdfDocuments.read();
};

reader.readAsDataURL(file);
