checking for new updates and/or applying them

[kir12]

due to the nature of caching with progressive web apps, it can be somewhat difficult to identify if new changes have been posted to a website and to get those changes in-place. For this reason, some system of checking, reminding, and/or automatic updating should be in-place:

• create a text file with a version number and place it in a folder on the repository that will be packaged by gh-pages: e.g. src, public, etc.
• Create a class UpdateCheck.tsx that, when subject to some trigger, grabs the same text file directly from the GitHub repo (e.g. via GitHub API?)
  • Compare the text file that's cached and the text file that's pulled down. Display the results in a Bootstrap Modal with corresponding styling (e.g. green for good, red for needs updating)
  • Conditionally display instructions for pulling down the newest version if needed
• Add an option in the menu to manually run this modal, and automatically run it once on initial page load
  • Always display the modal if manually queued via the menu, but only display the modal on initial page load if a newer version is found

follow-on optional augment:

• during the webpage deployment process, inscribe the running deployment's number as a text file via payload onto the page source
• have the github api read in the number of completed +running deployments and use that as a diff
