dev

Run the application in developer mode.

Usage

To run the app, run:

$ briefcase dev

The first time the application runs in developer mode, any requirements listed in a requires configuration item in pyproject.toml will be installed into the current environment.

Options

The following options can be provided at the command line.

-a <app name> / --app <app name

Run a specific application target in your project. This argument is only required if your project contains more than one application target. The app name specified should be the machine-readable package name for the app.

-r / --update-requirements

Update application requirements.

--no-run

Do not run the application; only install application requirements.

--test

Run the test suite in the development environment.

Passthrough arguments

If you want to pass any arguments to your app’s command line, you can specify them using the -- marker to separate Briefcase’s arguments from your app’s arguments. For example:

briefcase dev -- --wiggle --test

will run the app in normal mode, passing the --wiggle and --test flags to the app’s command line. The app will not run in Briefcase’s test mode; the --test flag will be left for your own app to interpret.
