Blaze is lit. It allows language-agnostic literate-style programming

blaze

in=$1

awk '{ if (/^```/) { i++; next } if ( i % 2 == 1) { print } }' < $in > $script

flask_demo.md

#!blaze

Execution

This is a python script, executed with pex

#!pex flask flask_restful --

Imports

First the imports, this demo requires the flask_restful package. Then we set up the Flask wsgi application object, app and the api wrapper, api.

from flask import Flask
from flask_restful import Resource, Api

app = Flask(__name__)
api = Api(app)

Flask Restful resources

We define a single HelloWorld resource, that responds with a simple json object on a GET request.

class HelloWorld(Resource):
    def get(self):
        return {'hello': 'world'}

Routing

api.add_resource() wires the Resource class HelloWorld into the flask router at /.

api.add_resource(HelloWorld, '/')

Run Server

After we have created everything, we run the flask werkzeug server.

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