How to Return JSON Responses in Flask Views?

Returning JSON Responses in Flask Views

When working with Flask views, the return value determines how the response is formatted. To return a JSON response, Flask provides the following options:

Option 1: JSON Serialization

Flask automatically serializes Python dictionaries or lists into JSON responses. To implement this:

@app.route("/summary")
def summary():
    d = make_summary()
    return d

Option 2: jsonify Function

For older Flask versions or when returning custom JSON-serializable objects, use the jsonify function:

from flask import jsonify

@app.route("/summary")
def summary():
    d = make_summary()
    return jsonify(d)

Both options effortlessly return the specified data as a JSON response, allowing for seamless integration with frontend applications.
