Webpacker: How to disable/remove webpacker from a project?

[gingerhot]

I tried webpacker in a project, and now I want to disable or remove the webpacker from it decently, but I failed to find how to in Docs and searching, and also there isn't a Rake task defined for this.

So some help will be appreciated.

Sometimes, you will need to disable things in order to successfully debug or test other things.

Disabling webpacker

1. Comment out webpacker from Gemfile.

#gem 'webpacker'

Remember to run bundle install

1. Comment out the single line on production and development.rb on the integrity check.

app/config/development.rb

#  config.webpacker.check_yarn_integrity = false

app/config/production.rb

#  config.webpacker.check_yarn_integrity = false

1. Comment out any javascript_pack_tag or stylesheet_pack_tag

app/views/*

<%# javascript_pack_tag "" %>
<%# stylesheet_pack_tag "" %>

1. Comment out any additional custom scripts/code/task that uses Webpacker

Update1: *I’m typing this on a phone and no access to laptop till night time. Will provide code snippet when I’m back

Feel free to add to the comments if I miss out anything.

@ytbryan Thanks for your rapid helping~

I commented out these lines, and the webpacker did not run compiling again when I run rails assets:precompile. But I found Rails still execute yarn install.

I'm not clear that if it's a feature of Rails 5 or because that webpacker hooks up a new webpacker:compile task to assets:precompile as documented here. If it was because of the later, how do I unhook it?

Thanks again ~

🤔 to give you an accurate answer, I need to trace the source code when I get back.

But at the back of my mind, I think you can:

1. Run ‘bundle exec gem uninstall webpacker’
2. And/or comment out the ‘.bin/yarn’ binstub

@ytbryan yes, it works. Thanks again~
