PR Summary

• Template modifications in artist.html The core structure of the artist.html file was modified by replacing a <main> element with a <section> element. Additionally, a link (anchor tag) was added to the footer of a card which should facilitate loading new data without refreshing the entire page.

• Addition of artwork.html A new file, artwork.html, was added to our system. This HTML template includes a specified title and body, allowing for the seamless creation of new artwork pages within our application.

• Added artwork route handler in artist.go
  A new mechanism (or "handler") was developed within artist.go to manage a specific user journey — navigating to artists/:name/:awid. This handler is responsible for fetching required data (either from a faster temporary storage in memory or a slower permanent storage on disk) and subsequently generating the desired HTML page for the user.

• HTML Response enhancements for new handler The HTML response created by our new handler also includes a special HX-Push-Url header. This addition allows us to change the URL in the user's browser without a full-page reload, streamlining the navigation experience on our website.
