See whether "Service Workers" are relevant

They seem pretty desirable:

• MDN guide: https://developer.mozilla.org/en-US/docs/Web/API/Service_Worker_API/Using_Service_Workers

Reading list

• tsconfig reference
• Triple-slash directives
• Guide blogpost, 2018: https://pacem.it/blogs/polyhedric/2018-07-11/pwa-with-typescript
• TypeScript TSDocs from Microsoft: https://microsoft.github.io/PowerBI-JavaScript/globals.html
• MDN references:
  • ServiceWorkerGlobalScope -- this is the global scope which the ServiceWorker script is executed inside of. Relates to TypeScript's lib option in tsconfig.
  • install event -- an ExtendableEvent. Relates also to lib of tsconfig.
• Immensely helpful StackOverflow post talking about how to organise one TypeScript project with both ordinary DOM scripts, and also WebWorker scripts: https://stackoverflow.com/questions/56356655/structuring-a-typescript-project-with-workers
  • Example project of building three components: DOM/Worker/ServiceWorker - https://github.com/jakearchibald/typescript-worker-example/

The next step is to try and set up some offline app-caching logic.

Turns out ServiceWorkers are extremely relevant. They are already being used in twitanalysis.
