Flask-Yeoman

A Flask blueprint to make create web application using Yeoman and Flask an easy task.

Features

• Automatically inject Flask config in index.html
• Support for development and production mode

Installation

$ pip install flask-yeoman

Getting Started

Create a server.py file in at the root of your yeoman app:

from flask import Flask, jsonify
from flask_yeoman import flask_yeoman

app = Flask(__name__)
app.register_blueprint(flask_yeoman)

if __name__ == "__main__":
    app.run(host='0.0.0.0', port=5000)

You can start working on your app as usual, and since it automatically injects Flask config allowing you to easily share configuration between Flask and your Backbone app (using the tojson` jinja helper):

<script>
window.myapp.config = {myvar: {{ config.MYVAR|tojson }},
                       myvar2: {{ config.MYVAR2|tojson }}};
</script>

Grunt configuration

In order to use your own server with Yeoman, you must create a new task in your Gruntfile.js file:

// New task for flask server
grunt.registerTask('flask', 'Run flask server.', function() {
   var spawn = require('child_process').spawn;
   grunt.log.writeln('Starting Flask development server.');
   // stdio: 'inherit' let us see flask output in grunt
   process.env.FLASK_YEOMAN_DEBUG = 1;
   var PIPE = {stdio: 'inherit'};
   spawn('python', ['server.py'], PIPE);
});

And replace the connect:reload task by flask in the server task:

grunt.registerTask('server', function (target) {
    if (target === 'dist') {
        return grunt.task.run(['build', 'open', 'connect:dist:keepalive']);
    } else if (target === 'test') {
        return grunt.task.run([
            'clean:server',
            'coffee',
            'createDefaultTemplate',
            'jst',
            'compass:server',
            'connect:test:keepalive'
        ]);
    }

    grunt.task.run([
        'clean:server',
        'coffee:dist',
        'createDefaultTemplate',
        'jst',
        'compass:server',
        'flask',
        'open',
        'watch'
    ]);
});

Livereload support

And for the livereload support, add this snippet before the closing body in your index.html file:

{% if config.FLASK_YEOMAN_DEBUG %}
<!-- livereload script -->
<script>document.write('<script src="http://'
+ (location.host || 'localhost').split(':')[0]
+ ':35729/livereload.js?snipver=1" type="text/javascript"><\/script>')
</script>
{% endif %}
