Jets Upgrade

This is a standalone CLI tool to help with jets upgrades.

• It can handle going from Jets v3 or v4 to Jets v5.

cd old-jets-project
jets-upgrade go

Before proceeding, the tool will prompt you with a "Are you sure" message.

Here are some of the things the tool does. It updates:

• config/application.rb: to the new inherited based style
• Rakefile: use Jets.application.load_tasks
• Gemfile: update to add jets v5 related gems and comment out the current ones in your Gemfile
• config/environment: update environment files to new config settings
• controllers: updates controller to use def destroy instead of def delete

It's unfeasible to account for all cases and Jets apps. This script cannot perform miracle upgrades. It's a best-effort script, and the hope is that this script gets you pretty far and is helpful. 😄

gem install jets-upgrade

By default, the jets-upgrade go command also tries to upgrade JavaScript. Jets v5 goes from webpacker to importmap. So, the node-related files are no longer needed. The upgrade command will remove node-related files. If you do not want this behavior, use the --no-javascript option.
