Project Description


A Relay-based web development kit on Flask.


  • Fast web development setup with ES6, React and Relay
  • Batteries included: React Router, Webpack and Babel
  • Server is powered by Python, Flask and Graphene
  • JWT integrated, with a working example using Flask-Login


  1. Install Relask:
pip install git+
  1. Create a Flask application, for example:
  2. Initialize your Flask application with Relask (this requires npm):
FLASK_APP=xxx flask init-relask
  1. Under the root path of your Flask application, create scripts/app.js with something like this:
import React from "react";
import ReactDOM from "react-dom";
import {Route, IndexRoute} from "react-router";
import Relay from "react-relay";
import {Relask, RelayContainer} from "babel-loader!relask";

class Hello extends React.Component {
    render() {
        return (
            <div>Hello, {}!</div>

    static relay = {
        fragments: {
            hello: () => Relay.QL`fragment on Hello { name }`

        <Route path="/" component={Hello} queries={{
            hello: () => Relay.QL`query { hello }`
), document.getElementById('app'));
  1. Initialize the Relask extension with something like this:
import graphene
from flask import Flask
from graphene import relay
from relask import Relask

class Hello(relay.Node):
    name = graphene.String()

    def resolve_name(self, args, info):
        return 'World'

    def get_node(cls, id, info):
        return Hello(id=id)

class Query(graphene.ObjectType):
    node = relay.NodeField()
    hello = graphene.Field(Hello)

    def resolve_hello(self, args, info):
        return Hello.get_node(1, None)

app = Flask(__name__)
relask = Relask(app)
relask.schema.query = Query
  1. See your result with one command - don’t worry about webpack any more:
FLASK_APP=xxx flask run


This package was created with Cookiecutter and the audreyr/cookiecutter-pypackage project template.
