Is the inclusion of square brackets necessary when transmitting data in JSON format?

Currently, I'm dealing with sending data in JSON format over the server.

Although I am facing issues with flask.jsonify(), that is a separate matter from this question.

To assist me in returning data in JSON format, I've turned to Marshmallow. By using marshmallow.Schema.dump(query), the output looks something like this:

[{'id': 1, 'title': 'title', 'content': 'some content'},
 {'id': 2, 'title': 'another title', 'content': 'some more content'},
 ...]

My query now focuses on whether the JavaScript file anticipates the content with or without the square brackets. I am under the impression it should be without the square brackets, which is what flask.jsonify() aims to remove, correct?

Answer №1

My suggestion is to always adhere to standard JSON format when you can; https://www.json.org/json-en.html

If your file only contains comma-separated values, it does not qualify as valid JSON. It is necessary to include square brackets to show that, on the top level, your JSON document is composed of a singular array.
