Custom output path

[aviemet]

Forgive me if this is documented, but I can't seem to figure out how to change the output path for the generated routes files. Using Rails 7 with Vite, I keep my frontend code in app/frontend, and so would like this gem to output routes to that directory. I would actually like them to be placed in a folder inside that directory. Is this currently possible?

Yes, use file configuration option: https://github.com/railsware/js-routes#generator-options

Thank you for pointing that out. I'm still having issues setting the output path, it seems that changes can only be made relative to app/javascript. I believe this is the location where that limitation is set:

js-routes/lib/js_routes/configuration.rb

Line 77 in e158c58

def output_file

All of the following configurations resulted in an error:

config.file = 'app/frontend/routes' 
# app/javascript/app/frontend/routes isn't a file
config.file = Rails.root.join('app', 'frontend', 'routes') 
# app/javascript/var/project/app/frontend/routes isn't a file
config.file = 'app/frontend/routes/routes.js' 
# app/javascript/app/frontend/routes doesn't exist
config.file = Rails.root.join('app', 'frontend', 'routes', 'routes.js') 
# app/javascript/var/project/app/frontend/routes doesn't exist

The closest I've gotten was using config.file = '../frontend/routes/routes.js', however this produced strange results. It generated the d.ts file in the specified path, but the routes.js file still generated in app/javascript.

In your last example: does app/frontend/routes directory exist? Can you make it and see if it fixes the issue?

[aviemet]

Yes, the directory existed and routes.d.ts generated there, but routes.js was placed in app/javascript, which also existed.

I can confirm this (js-routes 2.2.1). Last version it worked is 2.0.8

[bogdan]

Fixed in 2.2.2 👍

[GabrielErbetta]

Fixed in 2.2.2 +1

Can confirm it's working.
I had just updated to 2.2.1 from 1.4.x and was trying to find the problem. Thank you very much @bogdan .

This is still not working (app/assets/javascripts/) exists within my rails app:
config/initializers/js_routes.rb:
JsRoutes.setup do |c|
c.module_type = nil
c.namespace = 'Routes'
c.prefix = Figaro.env.url_prefix
c.file = 'app/assets/javascripts/routes.js'
end

rake js:routes
Errno::ENOENT: No such file or directory @ rb_sysopen - PATH/app/javascript/app/assets/javascripts/routes.js
