Meld is a framework for Flask that allows you to create dynamic user interfaces using Python and the Jinja2 templating engine.

Project description


Meld is a framework for Flask to meld your frontend and backend code. What does that mean? It means you can enjoy writing dynamic user interfaces in pure Python.

Less context switching. No need to write javascript. More fun!

Initialize Meld in your project

Example of how add Flask-Meld to a Flask application

from flask import Flask, render_template
from flask_meld import Meld

app = Flask(__name__)
app.config['SECRET_KEY'] = 'big!secret'
socketio = app.socketio

meld = Meld()

def index():
    return render_template("base.html")

if __name__ == '__main__':

Add {% meld_scripts %} to your base html template

<!DOCTYPE html>
        <title>Meld Example</title>
        <!-- Add the line below to include the necessary meld scripts-->
        {% meld_scripts %}

        {% block content %}
            <!-- Using a component in your template is easy! -->
            {% meld 'counter' %}
        {% endblock %}


Components are stored in meld/components either within your application folder or in the base directory of your project.

Components are simple Python classes. No magic here.

Here is an example of a Counter Component:

# app/meld/components/

from flask_meld.component import Component

class Counter(Component):
    count = 0

    def add(self):
        self.count = int(self.count) + 1

    def subtract(self):
        self.count = int(self.count) - 1


Create a component template in templates/meld/counter.html. By creating a file within the templates/meld directory just include {% meld 'counter' %} where you want the component to load.

Here is an example for counter:

<!-- templates/meld/counter.html -->
    <button meld:click="subtract">-</button>
    <input type="text" meld:model="count" readonly></input>
    <button meld:click="add">+</button>

Let's take a look at that template file in more detail.

The buttons use meld:click to call the add or subtract function of the Counter component. The input uses meld:model to bind the input to the count property on the Counter component.

Pretty simple right? You can use this to create very dynamic user interfaces using pure Python and HTML. We would love to see what you have built using Meld so please share!
