This demo relies on , Azure Computer Vision. Specifically you need an access key to interact with the service. You can create an Azure Free Account to try this demo.

Configure Access key

• In the src folder of this repo, create a file called .env with the following structure

OcrKey="<COMPUTER_VISION_KEY>"
UriBase='<URI_BASE>'
ReadResultLimit='<readResultLimit>'

Description of Variables:

Key	Purpose
OcrKey	Cognitive services computer vision key
UriBase	Url for the OCR service
ReadResultLimit	Number of retries to read the result from the OCR Service (optional, defaults to 3)

Running the Demo
