Post session plugin activation secret setup

[mensfeld]

I use Roda in a gem (karafka-web) and I want my own configuration flow to be able to setup the sessions plugin secret. Is there a way?

At the moment I have to:

plugin :sessions, key: '_karafka_session', secret: 'a' * 64

which runs when I load the code.

I would love to be able to do something like:

plugin :sessions, key: '_karafka_session', secret: -> { 'a' * 64 }

or any other way where I could alter the secret from a configuration I built after loading Roda app with its code but before starting it.

Is there a way?

If it will work for your use case, just load the plugin again after you know what the secret is, before freezing the application:

# Initially with bogus secret
plugin :sessions, key: '_karafka_session', secret: 'a' * 64

# later with actual secret, before freezing application
Karafka::Web::Ui::Base.plugin :sessions,  secret: 'b' * 64

Like most Roda plugins that accept options, you can load the sessions plugin multiple times and have the new options merged into the previous options.

Works as expected. Amazing. Thank you
