Errors when using browserify with a Rails Engine

[lucasprag]

I'm trying to use the browserify with a Rails engine.

I followed the Getting Started but I'm geting the error Uncaught ReferenceError: require is not defined when requiring the Vue npm package.

Any tip?

Thanks =)

I also tried to use a simple knock-knock-jokes wihout success. =/

I will commit a example app with the error as soon as possible.

I think another person was asking about this in the past (searching issues should turn it up). I'm not sure what the issue is but PRs are welcomed if you want to take the time to dive into it. I unfortunately do not know what would cause the issue. It might be worth looking at how the plugins mentioned here:

https://github.com/rails/sprockets-rails

Which would be coffee-rails and sass-rails work. That is, if they work inside an engine.

I see, thanks =) I'd love to contribute if there is a real problem with browserify-rails, but I think it's a configuration problem. Maybe I could write some instructions in the readme file.

I found the d7143df#diff-04c6e90faac2675aa89e2176d2eec7d8R151 and I followed the instructions.

First of all I changed the example.rb:

require "example/engine"

module Example
  class << self
    def config
      yield self
    end
  end
end

Then I changed the engine.rb:

require 'sprockets/railtie'
require 'browserify-rails'

module Example
  class Engine < ::Rails::Engine
    isolate_namespace Example

    config.browserify_rails.paths << lambda { |p| p.start_with?(Engine.root.join("app").to_s) }
  end
end

Now the error changed to Unable to run node_modules/.bin/browserify. Ensure you have installed it with npm., but I have installed the browserify with npm install as the readme instructions says.

I created a public example with this error: https://github.com/Lucasosf/example

Can you help me please @cymen ? =)

I finally found the problem.

The gem gets the config from Rails.application.config

There is no need to add configs to the engine.rb:

# lib/example/engine.rb
require 'sprockets/railtie'
require 'browserify-rails'

module Example
  class Engine < ::Rails::Engine
    isolate_namespace Example
  end
end

I just added the node_modules of the engine in the paths of the dummy app:

# test/dummy/config/application.rb
config.browserify_rails.paths << Rails.root.join('../../node_modules')

Now I can use npm packages in my isolated engine.

Thanks =D

Perhaps can I add some instructions of using browserify-rails in an isolated engine?

@Lucasosf Ah! Interesting. Yes, by all means instructions are very welcomed. You can fork and update the README and do a PR if that works for you. Sorry, I have been away for a bit and missed this thread until now.
