Webpacker: [Webpacker] Compiling 3-4x times per request

Created on 8 May 2018 · 7Comments · Source: rails/webpacker

Hello,
Having an issue where every request in Rails, Webpacker is compiling three to four times, which is making development very slow.
Getting messages like so:

I'm seeing webpacker compile on every request, even refreshing the same page.

@george-norris-salesforce For others to debug this issue, it would be helpful to post more info, e.g. your versions of the Webpacker gem, @rails/webpacker, Rails, etc., any configuration changes, what's in your packs directory. Help others reproduce.

Same here, I have webpacker 3.4 with rails 5 and docker, I'm having the same issue, the more complex is my app more time take to compile the assets, up to 5 mins!, I tried to run the webpack-dev-server but I get Cannot GET / message

webpacker (3.1.1)
We've renamed the folder. Other than that, no config changes

@george-norris-salesforce sorry what is the folder?

@george-norris-salesforce is it possible you're including either mini-css-extract-plugin or extract-text-webpack-plugin more than once? I believe for me, extract-text being ran several times was what was causing multiple compilation steps for me.

However, once I migrated to Webpacker 4.x and started using mini-css-extract-plugin instead I went back to only one compilation step.
