---

Import standard app resources from the specified folder.

This will import any resources that have been set to the Flask app.

Routes, context processors, cli, etc.

Can only be called once.

If no static and or template folder is found, the static and or template folder will be set to None in the Flask app config.

Small example of usage:

imp.import_app_resources(folder="resources")
# or
imp.import_app_resources()
# as the default folder is "resources"

Folder Structure: resources

app
├── resources
│   ├── routes.py
│   ├── app_fac.py
│   ├── static
│   │   └── css
│   │       └── style.css
│   └── templates
│       └── index.html
└── ...

File: routes.py

from flask import current_app as app
from flask import render_template


@app.route("/")
def index():
    return render_template("index.html")

How factories work

Factories are functions that are called when importing the app resources. Here’s an example:

imp.import_app_resources(
    folder="resources",
    factories=["development_cli"]
)

["development_cli"] => development_cli(app) function will be called, and the current app will be passed in.

File: app_fac.py

def development_cli(app):
    @app.cli.command("dev")
    def dev():
        print("dev cli command")

Scoping imports

By default, all files and folders will be imported.

To disable this, set files_to_import and or folders_to_import to [None].

imp.import_app_resources(scope_import=[None], folders_to_import=[None])

To scope the imports, set the files_to_import and or folders_to_import to a list of files and or folders.

files_to_import=["cli.py", "routes.py"] => will only import the files resources/cli.py and resources/routes.py

folders_to_import=["template_filters", "context_processors"] => will import all files in the folders resources/template_filters/*.py and resources/context_processors/*.py
