A good friend😉 suggested me to learn [GraphQL](https://hackernoon.com/tagged/graphql) and just when I was looking for resources, [HOW TO GRAPHQL](https://www.howtographql.com/) was launched.

I went with fundamentals of GraphQL in it and found [Graphene](http://graphene-python.org/) later. It’s a GraphQL framework for Python. I was more interested in Graphene-SQLAlchemy.

So I learned those stuff as well and came out with a [simple project](https://github.com/Getmrahul/Flask-Graphene-SQLAlchemy) for using GraphQL with Python-Flask using Graphene-SQLAlchemy.

In the [demo project](https://github.com/Getmrahul/Flask-Graphene-SQLAlchemy) I created a simple table “users” with field id, name, email, username. And, created a schema([schema.py](https://github.com/Getmrahul/Flask-Graphene-SQLAlchemy/blob/master/schema.py)) to

*   Add a new user.
*   Get all users list.
*   Find a user with username.
*   Update username with email ID.

Below are the example screenshots of GraphQL query execution:

You can try the demo project [here](https://github.com/Getmrahul/Flask-Graphene-SQLAlchemy). Looking forward to use [React](https://hackernoon.com/tagged/react) with the demo project stack. And do let me know if you find any typo or bugs. 👨‍💻 🙌
