Without understanding/thoroughly reading the code: is this Indexeddb cache optional? Will it fail without crashing the client?

Indexeddb might not be available in all browser contexts nor in NodeJS, so this needs to be purely optional and not affect the client if not available or unwritable/unreadable for any other reason.

Yes, it's in an Option and just does nothing when it's not available.

There's still an error in the web client compilation:

Generating main WASM for target nodejs...
error: 

it looks like the Rust project used to create this Wasm file was linked against
version of wasm-bindgen that uses a different bindgen format than this binary:

  rust Wasm file schema version: 0.2.95
     this binary schema version: 0.2.97

Currently the bindgen format is unstable enough that these two schema versions
must exactly match. You can accomplish this by either updating this binary or
the wasm-bindgen dependency in the Rust project.

You should be able to update the wasm-bindgen dependency with:

    cargo update -p wasm-bindgen --precise 0.2.97

don't forget to recompile your Wasm file! Alternatively, you can update the
binary with:

    cargo install -f wasm-bindgen-cli --version 0.2.95

if this warning fails to go away though and you're not sure what to do feel free
to open an issue at https://github.com/rustwasm/wasm-bindgen/issues!

We talked about adding a "last used" field so we can apply some sort of cache eviction in the future.

The wasm-bindgen version missmatch will go away when rebasing on top of albatross, as that dependency was updated recently to match.

Rebased on top of albatross.

Generally looks good to me. Left some minor comments only. It however does still have 2 clippy warnings for a RefCell which is held across an .await. Those should be reseolved.

I would also like to see some more rustdoc added, where it is missing.

Done.
