I’m finding the ‘serve directory’ setup a bit limiting, broken imports etc.
Is there any major disadvantage to running the Bokeh server within a Tornado app vs just bokeh serve?
Hi,
Following the existing examples, currently num_procs is limited to one until this is resolved:
Server(..., io_loop=io_loop, num_procs=0) --> RuntimeError · Issue #6439 · bokeh/bokeh · GitHub
There's probably some workaround to that butI have not had an opportunity to look further yet.
As an alternative, you might also consider defining your own application Handler to suit your needs:
https://github.com/bokeh/bokeh/tree/master/bokeh/application/handlers
An Application is just a collection of Handlers (usually one) that have a modify_doc method for creating the new doc for each new session. You can write your own Handler class with your own modify doc that handles directories or scripts differently. I am currently working on updating the docs for Application, but they won't be available on the dev docs site until next week, the above is the gist. Right now there's also not a way to "install" new handlers (maybe this is a motivating use case) but you could start the server the same way the "serve" command does:
https://github.com/bokeh/bokeh/blob/master/bokeh/command/subcommands/serve.py
except build applications to run differently using your custom handlers here:
https://github.com/bokeh/bokeh/blob/master/bokeh/command/subcommands/serve.py#L475
In fact, this would be the workaround to the issue above that I mentioned. And If you don't need or want to write a new handler, there's no reason you couldn't just just the existing FunctionHandler, e.g.
Thanks,
Bryan
