Flask-JSON 0.2.0

Better JSON support for Flask

Flask-JSON is a simple extension that adds better JSON support to Flask application.

Features:

• Works on python 2.6, 2.7, 3.3+ and Flask 0.10+.

• More ways to generate JSON responses (comparing to plain Flask).

• Extended JSON encoding support.

Usage

Here is fast example:

from datetime import datetime
from flask import Flask
from flask_json import FlaskJSON, JsonError, json_response, as_json

app = Flask(__name__)
FlaskJSON(app)


@app.route('/get_time')
def get_time():
    return json_response(time=datetime.utcnow())


@app.route('/get_time_and_value')
@as_json
def get_time_and_value():
    return dict(time=datetime.utcnow(), value=12)


@app.route('/raise_error')
def raise_error():
    raise JsonError(description='Example text.', code=123)


if __name__ == '__main__':
    app.run()
