To run such an application, you can use the :command:`flask` command:
.. tabs::
.. code-block:: text
.. group-tab:: Bash
$ flask run --app hello run
.. code-block:: text
Flask will automatically detect the factory if it is named
``create_app`` or ``make_app`` in ``hello``. You can also pass arguments
to the factory like this:
$ export FLASK_APP=myapp
$ flask run
.. code-block:: text
.. group-tab:: Fish
$ flask run --app hello:create_app(local_auth=True)``
.. code-block:: text
$ set -x FLASK_APP myapp
$ flask run
.. group-tab:: CMD
.. code-block:: text
> set FLASK_APP=myapp
> flask run
.. group-tab:: Powershell
.. code-block:: text
> $env:FLASK_APP = "myapp"
> flask run
Flask will automatically detect the factory (``create_app`` or ``make_app``)
in ``myapp``. You can also pass arguments to the factory like this:
.. tabs::
.. group-tab:: Bash
.. code-block:: text
$ export FLASK_APP="myapp:create_app('dev')"
$ flask run
.. group-tab:: Fish
.. code-block:: text
$ set -x FLASK_APP "myapp:create_app('dev')"
$ flask run
.. group-tab:: CMD

> set FLASK_APP="myapp:create_app('dev')"
> flask run
.. group-tab:: Powershell
.. code-block:: text
> $env:FLASK_APP = "myapp:create_app('dev')"
> flask run
Then the ``create_app`` factory in ``myapp`` is called with the string
``'dev'`` as the argument. See :doc:`/cli` for more detail.
Then the ``create_app`` factory in ``myapp`` is called with the keyword

In order to run the application you need to export an environment variable
that tells Flask where to find the application instance:
Install your application so it is importable:
.. tabs::
.. group-tab:: Bash
.. code-block:: text
$ export FLASK_APP=yourapplication
.. group-tab:: Fish
.. code-block:: text
$ set -x FLASK_APP yourapplication
.. group-tab:: CMD
.. code-block:: text
> set FLASK_APP=yourapplication
.. group-tab:: Powershell
.. code-block:: text
> $env:FLASK_APP = "yourapplication"
If you are outside of the project directory make sure to provide the exact
path to your application directory. Similarly you can turn on the
development features like this:
.. tabs::
.. group-tab:: Bash
.. code-block:: text
$ export FLASK_ENV=development
.. group-tab:: Fish
.. code-block:: text
$ set -x FLASK_ENV development
.. group-tab:: CMD
.. code-block:: text
> set FLASK_ENV=development
.. group-tab:: Powershell
.. code-block:: text
> $env:FLASK_ENV = "development"
In order to install and run the application you need to issue the following
commands::
.. code-block:: text
$ pip install -e .
$ flask run
To use the ``flask`` command and run your application you need to set
the ``--app`` option that tells Flask where to find the application
instance:
$ flask --app yourapplication run
What did we gain from this? Now we can restructure the application a bit
into multiple modules. The only thing you have to remember is the
