Example Code

import typer

# Direct alias on the Typer instance
db_app = type.Typer(name="database", aliases=["db", "data", "sql"])

# Support on the `command` decorator
# main command name is `create` or the value of the `name` attribute
@db_app.command(aliases=["new", "add"]):
def create():
    """Create new database"""


main_app = type.Typer()

# Add a new Alias when register
main_app.add_typer(db_app, aliases=db_app.aliases + ["pg"])

Description

Inspired by the click-contrib click-aliases

I think supporting aliases directly without the click complexity natively inside typer will be awesome.

I can write a PR to support this if you like.

Would it be possible to instruct click to do this as a workaround in the present moment?

I'll be happy to have this solution.
