'rake assets:precompile' not functioning properly

[hhutch]

Steps to reproduce:

1. default configuration options for browserify-rails
2. all node modules in ROOT/node_modules with ROOT/package.json
3. all JSX/React code in ROOT/app/assets/javascripts
4. App functions properly in develop mode
5. change config/environments/development.rb to 'config.assets.debug = true'
6. run

rake assets:precompile RAILS_ENV=development

RESULT:
browserify does not compile into a single JS asset and individual JS files (such as React libraries) are loaded but throw errors

Please let me know if I am making some sort of mistake, but as of now I have to revert to manual compilation as recommended in issue #27

assets:precompile should be run in production environment, so RAILS_ENV=production rake assets:precompile or simply rake assets:precompile, because this task uses the production environment by default, I think.

Does this fix it?

I get the same error running precompiled assets in both production and development modes. I am attempting to deploy to Heroku. Running with browserify-rails in development, not recompiling assets, works well.

I am using both NPM installed node_modules and writing many of my own components for use in a React UI.

Hi. I'm having this very same issue on Rails 3.2.17. What I am observing is that the Rails engine is not being registered when I run rake assets:precompile. It works fine with development-mode runtime asset compilation.

It's also not clear from the Readme which versions of Rails are supported. I would guess at least 3.2 and up?

It works fine when I run RAILS_ENV=production rake assets:precompile on my local.
But it throw the following error message when I push to heroku master:

I've got same error as michael-ns when pushing to heroku. If I include node-modules folder into the repo I get Errno::EPIPE: Broken pipe error. Any suggestions?

As a workaround you can disable asset compilation for production and sync manually with rake assets:precompile RAILS_ENV=production

I'm having the same problem.

Currently doing what @ikido suggested and it works but it's not the ideal.

I had same issue as @michael-ns and found the solution.
Here is what I did.

@chikathreesix thanks a lot for finding the solution to this.
Anyway, when you write:

Create .buildpack file for the multi-buildpack to make sure node.js is compiled before ruby.

I think the file has to be named .buildpacks instead of .buildpack (http://stackoverflow.com/a/14801582)

[chikathreesix]

@joaovpmamede thank you for pointing this out.
Yeah, you're correct. I've fixed the blog post.

Hello I have the same issue with this output and rails setup https://gist.github.com/kfamilonidis/e21e2b7e088732e684fb
I haven't found any resolution yet other than to manually run.

NODE_VERSION=v5.0.0 RAILS_ENV=production /usr/local/rvm/bin/rvm default do bundle exec rake assets:precompile

=== UPDATE

solved - I replaced the double quotes with single ones on the browserify parameters and worked!

config.browserify_rails.commandline_options = "--transform reactify --extension='.jsx'"

insead of

config.browserify_rails.commandline_options = "--transform reactify --extension=\".jsx\" ".

@kfamilonidis It's awesome that you found a fix for this issue, thanks! Active development for browserify-rails has actually moved to https://github.com/browserify-rails/browserify-rails, so it'd be great if you could share your findings there :)
