Frappe Apps are Python packages which use the Frappe platform. They can live
anywhere on the Python
and must have an entry in the
Creating an app
Frappe ships with a boiler plate for a new app. The command
app-name helps you start a new app by starting an interactive shell.
% bench new-app sample_app App Name: sample_app App Title: Sample App App Description: This is a sample app. App Publisher: Acme Inc. App Icon: icon-linux App Color: #6DAFC9 App Email: firstname.lastname@example.org App URL: http://example.com App License: MIT
The above command would create an app with the following directory structure.
sample_app ├── license.txt ├── MANIFEST.in ├── README.md ├── sample_app │ ├── __init__.py │ ├── sample_app │ │ └── __init__.py │ ├── config │ │ ├── desktop.py │ │ └── __init__.py │ ├── hooks.py │ ├── modules.txt │ ├── patches.txt │ └── templates │ ├── generators │ │ └── __init__.py │ ├── __init__.py │ ├── pages │ │ └── __init__.py │ └── statics └── setup.py
The boiler plate contains just enough files to show your app icon on the [Desk].
Files in the app
hooks.py file defines the metadata of your app and integration points
with other parts of Frappe or Frappe apps. Examples of such parts include task
scheduling or listening to updates to different documents in the system. For
now, it just contains the details you entered during app creation.
app_name = "sample-app" app_title = "Sample App" app_publisher = "Acme Inc." app_description = "This is a sample app." app_icon = "fa-linux" app_color = "black" app_email = "email@example.com" app_url = "http://example.com" app_version = 0.0.1
Modules in Frappe help you organize Documents in Frappe and they are defined in
modules.txt file in your app. It is necessary for every [DocType] to be
attached to a module. By default a module by the name of your app is added.
Also, each module gets an icon on the [Desk]. For example, the [ERPNext] app is
organized in the following modules.

Adding app to a site
Once you have an app, whether it's the one you just created or any other you downloaded, you are required to do the following things.
Download the app via git
bench get-app https://github.com/org/app_name
Install the app to your site
bench --site site_name install-app app_name
