In dev the app uses the webpack-dev-server to serve the files locally.
The server can be started with npm start. The app is served on port :3000.
To build the app for production, run npm run build. The build appears in the /dist folder. All TypeScript is bundled
together. The custom CSS is minified and injected in a <script> tag in index.html.
The data for the app originates from the videos-info.json file. This file is included in the /dist folder and a URL to it
is emitted by Webpack. This way the file can be loaded dynamically into the app. More on this here:

The videos-info.json is refreshed by an AWS Lambda function every 6 hours. The lambda runs the script /backend/lambda/update_data.py,
which fetches the latest statistics from YouTube for all videos listed in videos-info.json and merges them into the file.
The website is hosted on AWS in an S3 bucket. This is its URL: https://www.glasat2020.com.
