This repository shows how to use the STRICH SDK to create a barcode scanning application with just plain JavaScript (ES6), HTML and CSS, without using any framework or build tooling.
The app implements three basic scanning workflows that are popular in real-world use cases:
- Single scan: scans a single barcode and returns the home screen
- Repeated scans: scans barcodes repeatedly, with a user interaction between scans
- Multiple scans: scans multiple barcodes until some condition is met
The app still needs to be served from a secure origin. For development purposes, we've included a Python script serve_https.py to show how to use Python's built-in capabilities to quickly create a development server.
To create a self-signed certificate, check out any guide on the internet or this Stackoverflow answer: https://stackoverflow.com/a/41366949/1370154
Then run the script in this directory to serve the app over an HTTPS connecting using the self-signed certificate:
$ python3 serve_https.py tls_key.pem tls_cert.pemAnother popular option is to serve the application locally (by using serve_http.py for instance) and expose it via ngrok or similar tools, with an automatically created TLS certificate and public DNS.
