manage multiple sites with one setup?

[huglester]

Hello

anyone managed to set up some sometup, so we can use it in multiple src/dst/package.json environments?

I have 10+ sites setup, which are very similar, just different css files,js and similar.

but doing smth like that 'build' => [
'source' => '_src/{env}',
'destination' => '_prod/{env}',
],

does not try to do anything working. Starts complaining with mix-manifest.json missing and such.

Thank you
