The article demonstrates how to improve the default help display in a Typer CLI application. Originally, the application only provides an error message unless the user explicitly requests help. By implementing the `@app.callback` decorator with `invoke_without_command=True`, the application can showcase its help message automatically if no command is invoked, creating a more user-friendly experience. The revised output includes general options and commands, highlighting Typer's elegance and ease of use in building command-line interfaces.
Now we get something as a default that really shows off the charm of `typer`: ```plaintext $ python cli.py Usage: cli.py [OPTIONS] COMMAND [ARGS]... Awesome CLI app Options --install-completion Install completion for the current shell. --show-completion Show completion for the current shell, to copy it or customize the installation. --help Show this message and exit. Commands create Creates a user delete Deletes a user ```
