As of Flask 1.1.0 a view can directly return a Python dict and Flask will call jsonify
automatically.
@app.route("/summary") def summary(): d = make_summary() return d
If your Flask version is less than 1.1.0 or to return a different JSON-serializable object, import and use jsonify
.
from flask import jsonify @app.route("/summary") def summary(): d = make_summary() return jsonify(d)
