Flask-Web3
==========
Flask-Web3 is a flask extension allowing to smoothly integrate a flask application with `web3.py`_.
This package is intended for developers will to build a Flask application that interacts with an Ethereum client.
.. _`web3.py`: https://github.com/ethereum/web3.py
Requirements
~~~~~~~~~~~~
- Python>=3.5
A simple example
~~~~~~~~~~~~~~~~
.. code-block:: python
>>> from flask import Flask, jsonify
>>> from flask_web3 import current_web3, FlaskWeb3
# Declare Flask application
>>> app = Flask(__name__)
# Set Flask-Web3 configuration
>>> app.config.update({'ETHEREUM_PROVIDER': 'http', 'ETHEREUM_ENDPOINT_URI': 'http://localhost:8545'})
# Declare Flask-Web3 extension
>>> web3 = FlaskWeb3(app=app)
# Declare route
>>> @app.route('/blockNumber')
... def block_number():
... return jsonify({'data': current_web3.eth.blockNumber})
You can notice that Flask-Web3 gives you an application context bound variable ``current_web3`` that is accessible
from any active flask application context.
An advanced example
~~~~~~~~~~~~~~~~~~~
You may like to declare your Flask-Web3 extension from a customize Web3 class with enhanced logic.
.. code-block:: python
>>> from flask import Flask, jsonify
>>> from flask_web3 import current_web3, FlaskWeb3
>>> from web3 import Web3
# Declare Flask application
>>> app = Flask(__name__)
>>> app.config.update({'ETHEREUM_PROVIDER': 'http', 'ETHEREUM_ENDPOINT_URI': 'http://localhost:8545'})
# Declare a custom Web3 class
>>> class CustomWeb3(Web3):
... def customBlockNumber():
... return self.eth.blockNumber
# Associate a custom FlaskWeb3 extension
>>> class CustomFlaskWeb3(FlaskWeb3):
... web3_class = CustomWeb3
# Declare customized web3 extension
>>> web3 = CustomFlaskWeb3(app=app)
>>> isinstance(web3, CustomWeb3)
True
# Declare route
>>> @app.route('/customBlockNumber')
... def last_odd_block_number():
... return jsonify({'data': current_web3.customBlockNumber()})
