Minimal example using Inject to inject a string into a Typer command.

import typer from typer_injector import Inject, configure def config(binder): binder.bind(str, "Hello from DI!") configure(config) app = typer.Typer() @app.command() def greet(message: str = Inject()): typer.echo(message) if __name__ == "__main__": app()

Debug

Known issues

gotchaThe `Inject` type annotation must be used as a default argument value (e.g., `message: str = Inject()`). Using it without parentheses or in other positions will not trigger injection.

fix

Always use `Inject()` as the default value, not `Inject`.

affects: all

gotchaThe `configure` function must be called before defining any Typer commands that use `Inject`, otherwise injection may not work.

fix

Call `configure(config)` at module level before defining commands.

affects: all

deprecatedThe library is in early development (0.x) and APIs may change without notice. There is no stable release yet.

fix

Pin to a specific version and test upgrades carefully.

affects: <1.0.0
