Local by Flywheel + Laravel Herd, best of both worlds! Use Local for pushing and pulling and Herd for local development (so you can use the Dumps window and test emails). If you put these in your herd bin folder, you can run "local-to-herd" from anywhere to transfer the site's database and link the install to Herd's server, and "local-export-db"…

# This is a custom script that automates the transition of a WordPress site
# from Local by Flywheel to Laravel Herd for local development.
# When placed in your user directory -> .config/herd/bin alongside a .bat file to run it,
# you can run it from anywhere using the command "local-to-herd" in PowerShell.

# Common variables

# Just check first that the alias is resolving to the correct MySQL instance using "Get-Command mysql".
