Webpacker has been retired 🌅
For applications currently using Webpacker, the first recommendation is to switch to jsbundling-rails with Webpack (or another bundler). You can follow the switching guide, if you choose this option.
The development of v6 will not result in an official gem released by the Rails team nor see any future support. But Justin Gordon is continuing that line of development – including a focus on hot-module reloading features etc – under a new gem called Shakapacker that is based on the unreleased v6 work from this repository.
Thank you to everyone who has contributed to Webpacker over the last five-plus years!
Please refer to the 5-x-stable branch for 5.x documentation.
