Enhancement: Set a 'required' parameter for a frontmatter field that will annoy editors until it is defined.

[bwklein]

Is your feature request related to a problem? Please describe.
Some fields need to be filled in for the site design to work as intended and for SEO.

Describe the solution you'd like
Set a parameter required: true on a content type field, that will first highlight the field red when not filled out, and then raise a warning on save until the field is filled out. Basically, be annoying to the editor until the requirements are satisfied.

Describe alternatives you've considered
Telling people to remember to fill it out, checklists, pre-build script to check all files for required fields. It would be better to have some information in the UI at the time of editing, instead of after the files are saved, committed to the repo.

@estruyf I was asked about this today and wanted to see what you thought about it.

[estruyf]

Hi @bwklein, sorry for the delay. I am just back from vacation, so I need to get up to speed with all the things I missed.

[zivbk1]

@estruyf no worries, I was hoping that you were off doing something fun and relaxing this summer. :D

[estruyf]

Good news @zivbk1 @bwklein - there has been some good progress on this, and it will soon be available for testing.

This is now available for testing.

Configuration

• Add the required property to the fields in your content type you want to define as a required field
• You will automatically get the notification if you save the file and a required field is missing, if you don't want to see this notification, you can disable it with the new frontMatter.global.notifications.disabled setting and add the [requiredFieldValidation] its value.

This is excellent! Thank you.
