An improved shell command for the Flask CLI

Project Description

An improved shell command for Flask

Flask-Konch adds an improved shell command, flask konch, to the Flask CLI.

Benefits of flask konch over flask shell

  • Uses IPython, BPython, or ptpython if available, and falls back to built-in interpreter
  • Automatically imports top-level Flask functions and classes by default
  • Define additional variables to include in the shell context
  • Configurable banner and prompt

Flask-Konch uses konch, a shell configuration utility, under the hood.

Get it now

pip install flask-konch


To run the shell:

export FLASK_APP=path/to/
flask konch

To add additional variables to the shell context:

app = Flask(__name__)
      'db': database,
      'User': User,

Configuration options

  • KONCH_CONTEXT_FORMAT: Format to display shell context. May be 'full', 'short', or a function that receives the context dictionary as input and returns a string.
