Flask boilerplate to create projects with the idea of pluggable blueprints.
pip install blueflask
The following command allows you to create a new app:
.. code-block:: python
blueflask newapp <APP_NAME> <OPTIONAL_DEST_DIRECTORY>
Creating A New App
Let's assume that we are going to start a project called **bluedemo**. Execute
on your terminal:
blueflask newapp bluedemo
This will create a directory with the name of the project and define a basic
structure for your project layout.
Running The APP
Next, go inside the directory of your project and install the dependencies.
If you are using *virtualenv* then, create and/or activate your environment
before executing the following command bellow install your dependencies.
pip install -r requirements.txt
Now your project is ready to run. Execute the following command to start
Or you can execute one of the Flask standard ways to run the application:
python -m flask run
Either one will start the application running on port 5000. Now you can go to
your browser and enter:
You can play with some URLs like: `http://localhost:5000/demo/about/?value=some_random_value<http://localhost:5000/demo/about/?value=some_random_value>`_
As you can see, the last two URLs have a */demo* prefix. This is defined in the *blueprints/demo/config.py* file by the *url_prefix* under the *BLUEPRINT_INIT* dictionary. You can change the value of this for whatever you want or set it to *None* if you don't want any prefix.
Understanding Your Application
Now that you have your application running, have a look to the basic architecture defined by BlueFlask. Look inside the *app/blueprints*
directory. As you can see, there is a *main* and a *demo* directory. These directories are consider *pluggable-blueprint*, according to the BlueFlask idea. The structure of this directory is pretty simple:
+ *__init__.py:* Makes the current directory a Python package.
+ *config.py:* Blueprint specific settings and definitions.
+ *urls.py:* Routes for that blueprint.
+ *views.py* Functions or classes in charge of handing requests.
Feel free to define more modules as you need them. I.e: *models.py*,
*service.py*, *utils.py*, etc.
Creating A New Blueprint.
To create a new blueprint, you just have to create a new directory inside
the *blueprints* directory.
