We are using React on Rails within our Rails app. When we deploy, asset pre-compilation takes ~20 minutes.

Based on the deploy logs, it appears as though most of this time is spent pre-compiling a 3.3MB javascript file. That file "app.js" concatenates two files which are generated by webpack:

# app.js

//= require vendor-bundle (250KB)

//= require app-bundle  (3.3MB)

Should we just come to expect long pre-compile times given the size of the app-bundle? Or, can we improve things?

As an additional note, we tried directly compiling app-bundle, instead of requiring it through app.js, and it took the same amount of time.

It is hard to answer this question without knowing what leads to this error and this needs a debugging but as of now I came to this problem once, I would suggest you break the code into a new project which will help you to connect your Rails app through API and with this the complexity of your devops and deployment pipeline will greatly be reduced. I came to this conclusion after debugging. Hope this information will give a basic idea about how to approach your problem.
