Prompt user for (meta)data on file upload

Question

[context] I am working with sharepoint online, using modern views. i have a webpage with a document library attached.

[goal] I would like to prompt a user to fill out all required (meta)data about a document when they upload a document to the document library.

[faced issues] Many solutions I find online are either for older SP-versions or already outdated custom web parts. But without proper documentation (proper != microsoft documentation) about spfx I'm not getting much further by adjusting these webparts.

I'm open to any form of solution.

[if more info is required please do tell]

Answer 1

Yes this is missing from the modern experience, We have developed our own upload web part where we control the upload behavior

• which fields are required
• what type of files (.docx, .pdf) can be uploaded to library.

What you could do alternatively you could create an Flow that would prompt user to enter the missing metadata.
