assets:precompile fails in production due to missing manifest.yml

[drborges]

Help us help you! Please choose one:

• My app crashes with react-rails, so I've included the stack trace and the exact steps which make it crash.
• My app doesn't crash, but I'm getting unexpected behavior. So, I've described the unexpected behavior and suggested a new behavior.
• I'm trying to use react-rails with another library, but I'm having trouble. I've described my JavaScript management setup (eg, Sprockets, Webpack...), how I'm trying to use this other library, and why it's not working.
• I have another issue to discuss.

rake assets:precompile:all fails while deploying to production. I suspect the problem is that I have the following configuration:

config.assets.compile = false
config.assets.prefix = "ui"

Which causes the manifest.yml to be generated under public/ui instead of public/assets, thus failing the initialization of the YamlManifestContainer

On a quick attempt to fix the issue, I tried this but then, assets:precompile fails cause it cannot find react-server.js. Any thoughts?

Sorry about that!

assets:precompile fails cause it cannot find react-server.js

Could you share the stack trace for that?

[drborges]

No need to be sorry :)

Just to highlight, that only happens with the potential fix for the missing manifest I mentioned above, here's the stack trace:

No compiled asset for react-server.js, was it precompiled?

[drborges]

the issue regarding the react-server.js could be a side effect of my attempt to fix the missing manifest.yml.

[rmosolgo]

Is react-server configured to be precompiled? eg

Rails.application.config.assets.precompile += ['react-server.js']

This is needed in some cases but I can't remember which :S

[drborges]

It is not, let me try that.

[drborges]

didn't work.

what should be the path for react-server.js?

[drborges]

shouldn't I see react-server.js in my manifest.yml?

[rmosolgo]

shouldn't I see react-server.js in my manifest.yml?

Yes, I think so, but I don't understand why it doesnt :S

The last suggestion I have is to do a wholesale workaround: #443 (comment)

Sadly react-rails has these defaults for the asset pipeline, but then when the asset pipeline is configured differently, the defaults don't work! 😖 I want to change those defaults but it will be a breaking change, so I've put it off!

[drborges]

Thanks for the help @rmosolgo, I'll try that next.

[rmosolgo]

I hope it worked for you after that patch!
