问题 Final goal: an Angular client receives a token valid for one hour in order to query data from FireStore.

问题 I working in a firebase database. I need to limit the length of a string field. How do I do that? The path to the field is: Col1/doc1/ / /description That is, starting with the collection col1, then into doc1, then for all collections under doc1, and all documents under that collection, the description field needs to be limited to 100 characters.
