Does `$TRUNK_STAGING_DIR` work in `post_build` hook? about trunk HOT 3 CLOSED

Ah, I needed to run prettier inside a shell. This works for Trunk.toml:

[[hooks]]
stage = "post_build"
command = "sh"
command_arguments = ["-c", "prettier --write $TRUNK_STAGING_DIR/index.html"]

from trunk.

As a warning to others, in my experience both of the HTML formatters prettier and tidy break the resulting index.html. When looking at the JavaScript Console in the browser developer tools, there are thousands of websocket failures. I'm not sure why exactly. It would seem that both tools default to making changes that they think are innocuous but are not. I chose not to spend time chasing rabbits down that hole.

Yes, $FOO is a construct which is evaluated by the shell, passing it as an argument will pass the literal $FOO to the application. But using bash like you did solves the issue.

Running trunk serve will inject some WebSocket code for reloading the application "on change". However, running this only for releases (trunk build --release) should be fine I guess.
