It is feasible. In my solution I used GWT-RPC's serialization but I had to
tweak it since GWT-RPC messages are assymetric (the message sent from the
client to the server is in a different format than the message sent from
the server to the client even if they transfer the same object). Basically
you have to make the serialization symetric. I did this by implementing the
streamwriter to output the same message that the serverside would output. I
did this basically by porting the server code to the gwt side. I then
leveraged the already existing reader in the client and generated (by using
generators) a class that returns the desired reader and writer. The reader
is of course used to read the string and outputs the object and the writer
takes the object and outputs the string. By using this method you can not
only save results from RPC calls but any serializable object in the
LocalStorage.
Since the storage in the LocalStorage is limited a further improvement is
to compress the string. For this I use the LZMA algorithm which can
compress the strings to about 60% of their original size. Based on my
tests, bigger objects compress better but this is based on objects in my
project and might not be the case for other kinds of objects.
Hope this helps.
