Flask-Rich

Flask-Rich is a Flask extension that implements the Rich programming library with Flask, which brings better logging / tracebacks with rich text formatting, and more features related to the console.

Features

• 🌈 Better console logging powered by Rich's logging handler, with full support for console markup, highlighting, tracebacks and more
• 🚧 Builtin support for Werkzeug which runs the Flask development server
• 🔍 A new rich-routes Flask command that use Rich to show all routes
• 🔧 Customizable and toggleable features

Basic Usage

Just like any other Flask extension, you can initialize and register Flask-Rich with your Flask app in two ways:

Single File

from flask import Flask
from flask_rich import RichApplication

class Config:
    RICH_LOGGING = True

app = Flask(__name__)
app.config.from_object(Config())  # or any other way to load config

# Initialize the extension with the app
rich = RichApplication(app)

@app.route("/")
def index():
    return "Hello World!"

Factory Pattern

# rich.py
from flask_rich import RichApplication

# Initialize the extension without an app
rich = RichApplication()

# app.py
from flask import Flask
from .rich import rich

class Config:
    RICH_LOGGING = True

def create_app:
    app = Flask(__name__)
    app.config.from_object(Config())  # or any other way to load config

    # Register the extension with the app
    rich.init_app(app)
    # ...
    return app

After registering, the RichApplication class shall do all the work for you.

You can now use the app.logger object to log rich text, and use the flask rich-routes command to show all routes.

For further usage and configuration, please refer to the documentation.
