Flask-ResponseBuilder 2.0.9

Implementations of flask response in many format notation

Implementations of flask response in many formats: base64, csv, json, xml, html, yaml. You can create your own builder extending Builder class and registering it with register_builder method.

Every builders are registered as attribute of ResponseBuilder class so you can invoke method from this class with builder’s name and it automatically create a response with that builder.

Also you can used Builder without response by invoking static methods: to_me, to_dict.

Based on PyYAML, xmltodict, dicttoxml. See their documentation for other options.

• Decorator for http response status 204 NO_CONTENT

• Response based on Accept header of request

• Response based on format parameter (query string)

• template_or_json: response based on xhr request (deprecated: works only with old js library)

• Support for case notation checker and converter, see Case utility class.

• Transformer: utility class for data notation conversion

Quickstart

Install flask_response_builder using pip:

$ pip install Flask-ResponseBuilder

Then import it into your project:

$ from flask_response_builder import ResponseBuilder

Example usage

app = Flask(__name__)
app.config['RB_HTML_DEFAULT_TEMPLATE'] = 'response.html'
rb = ResponseBuilder(app)

@app.route('/nocontent')
@rb.no_content
def nocontent():
    pass

@app.route('/xhr')
@rb.template_or_json('response.html')
def test_xhr():
    return data

@app.route('/onaccept')
@rb.on_accept(acceptable=['application/json', 'application/xml'])
def test_accept():
    return data

@app.route('/format')
@rb.on_format()
def test_format():
    return data

For every registered builder you can explicitly use them in two ways:

@app.route('/decorator')
    @rb.response('json')
    def test_decorator():
        return data, 200, {'header': 'header'}

@_app.route('/csv')
def index_csv():
    builder = rb.csv(filename='file.csv')
    return builder((data, 200))
