InfluxDB-Flask

Documentation: InfluxDB-Flask Documentation

Introduction

InfluxDB went for a massive change from v1.7 to v2.0. They introduced a new client library influxdb-client-python to interact with the InfluxDB v2 API. InfluxDB-Flask adds influxdb-client-python support to Flask.

Note: Use this library with InfluxDB 2.x and InfluxDB 1.8+. For connecting to InfluxDB 1.7 or earlier instances, use the Flask-InfluxDB that uses InfluxDB-Python as client library.

The API of the influxdb-client-python is not the backwards-compatible with the old one - influxdb-python.

Installation

Install the extension via pip:

$ pip install influxdb-flask

Set Up

Influxdb_client can be accessed via InfluxDB class:

from flask import Flask
from influxdb_flask import InfluxDB

app = Flask(__name__)
influxdb = InfluxDB(app)

Delayed configuration of InfluxDB is also supported via init_app method:

influxdb = InfluxDB()

app = Flask(__name__)
influxdb.init_app()

Currently InfluxDB.connection instance provides the functionality of InfluxDBClient .

An included example shows how to write and query data from InfluxDB.

Configuring InfluxDB-Flask

The following configuration values can be set for InfluxDB-Flask extension:

INFLUXDB_V2_URL                       InfluxDB server API url. Default is <http://localhost:8086>
