I'm wondering if it would not be better to rename this field to custom_js instead of script.
I know that there is an existing stylesheet field, but it would have been better to use custom_css.

Instead of reusing $stylesheetNonce, it would be preferable to rename this variable to something generic, for example: $cspNonce.
What is the benefit of using type="module" here?

With type="module" you can use import and top-level await. In short, makes it easier to use modern JS features without a bundler, which is quite nice for something like this IMHO.

Can you please rename Script to CustomJS

The CSP is incorrect. The script-src directive should always includes self otherwise it won't load the application JS files.
it should be something like this: script-src 'self'{{ if .user.Script }} 'nonce-{{ $cspNonce }}'{{ end }}

Oh, that explains a regression I started noticing after the rebase. Fixed.

@milhnl You forgot to rename .user.Script to .user.CustomJS in the template.

My bad. Had a very busy week. Thanks for merging! Learned a lesson in trusting gopls' rename feature 😇 |
This PR adds the Custom JS option.
I tried to follow the "Custom JS" translations, and have been running this for myself for about a week now.
I know I am not good at testing software. I don't really know what could break, I tried adding a script, and removing it, but this isn't a feature with a lot of varying code paths. Feedback is very welcome! I don't really have a lot of experience with Go.
Fixes #1742
