Playground swap git hook

[chrisolsen]

Steps needed to test

Run the npm run pg:setup script (it can be run multiple times)

Switch branches either by command line or your IDE. The playgrounds should auto-swap and create a new one if it doesn't already exist.

⚠️Caution: back up your existing playground dir before testing this just in case.

@chrisolsen I ran npm run pg:setup on MacOS 26.0. I got the following error:

sh: ./scripts/pg-setup: /usr/bin/bash: bad interpreter: No such file or directory

I switched the shebang line to #!/bin/sh and then it worked as expected.

I tested on my local and it works:

thytran142@Trans-MacBook-Pro new-ui-components % npm run pg:setup

> @abgov/ui-components@0.0.0 pg:setup
> ./scripts/pg-setup

Do you want to automate playground swapping? (yes/no) yes
