Purpose

A generic footer for Open edX micro-frontend applications. It includes a logo and an optional language selector dropdown.

Getting Started

Prerequisites

The devstack_ is currently recommended as a development environment for your new MFE. If you start it with make dev.up.lms that should give you everything you need as a companion to this frontend.

Note that it is also possible to use Tutor_ to develop an MFE. You can refer to the relevant tutor-mfe documentation_ to get started using it.

.. _Devstack: https://github.com/openedx/devstack

.. _Tutor: https://github.com/overhangio/tutor

.. _relevant tutor-mfe documentation: https://github.com/overhangio/tutor-mfe#mfe-development

Requirements

This component uses @edx/frontend-platform services such as i18n, analytics, configuration, and the AppContext React component, and expects that it has been loaded into a micro-frontend that has been properly initialized via @edx/frontend-platform's initialize function. Please visit the frontend template application to see an example. <https://github.com/openedx/frontend-template-application/blob/3355bb3a96232390e9056f35b06ffa8f105ed7ca/src/index.jsx>_

Environment Variables

This component requires that the following environment variable be set by the consuming micro-frontend.

• LMS_BASE_URL - The URL of the LMS of your Open edX instance.
• LOGO_TRADEMARK_URL - This is a URL to a logo for use in the footer. This is a different environment variable than LOGO_URL (used in frontend-component-header) to accommodate sites that would like to have additional trademark information on a logo in the footer, such as a (tm) or (r) symbol.

Installation

To install this footer into your Open edX micro-frontend, run the following command in your MFE:

npm i --save @opencraft/frontend-component-footer

This will make the component available to be imported into your application.

Cloning and Startup

.. code-block::

1. Clone your new repo:

``git clone https://github.com/openedx/frontend-component-footer.git``

2. Use node v18.x.

The current version of the micro-frontend build scripts support node 18.
Using other major versions of node *may* work, but this is unsupported.  For
convenience, this repository includes an .nvmrc file to help in setting the
correct node version via `nvm <https://github.com/nvm-sh/nvm>`_.

3. Install npm dependencies:

``cd frontend-component-footer && npm ci``

4. Start the dev server:

``npm start``

Usage

This library has the following exports:

• (default): The footer as a React component.
• messages: Internationalization messages suitable for use with @edx/frontend-platform/i18n <https://edx.github.io/frontend-platform/module-Internationalization.html>_
• dist/footer.scss: A SASS file which contains style information for the component. It should be imported into the micro-frontend's own SCSS file.

• onLanguageSelected: Provides the footer with an event handler for when the user selects a language from its dropdown.
• supportedLanguages: An array of objects representing available languages. See example below for object shape.

Customization via MFE config API

Other than the environment variables listed above, it is also possible to customize the footer via MFE config API <https://github.com/openedx/edx-platform/blob/master/lms/djangoapps/mfe_config_api/docs/decisions/0001-mfe-config-api.rst>_. Below is the possible list of settings

.. code-block:: python

MFE_CONFIG = { # Update footer container styling "FOOTER_CUSTOM_STYLE": { "backgroundImage": "url(http://)", # to change opacity of background image # "backgroundImage": "linear-gradient( rgba(255, 255, 255, 0.85), rgba(255, 255, 255, 0.85) ) , url(http://)", }, # Update footer container styling via bootstrap classes "FOOTER_CUSTOM_CLASSNAMES": "py-5 px-4 text-center flex-column justify-content-center flex-wrap text-dark", # Update footer inner conatiner styling via bootstray classes "FOOTER_CONTAINER_CUSTOM_CLASSNAMES": "py-5 px-4 text-center flex-column justify-content-center flex-wrap text-dark" # Update footer logo styling "FOOTER_LOGO_STYLE": { "marginBottom": "2rem", }, # Override environment variable "LOGO_TRADEMARK_URL": "https://", # Add links to footer "FOOTER_LINKS": [ {"url": "https://openedx.org/terms-of-use/", "text": "Terms of service"}, {"url": "https://openedx.org/code-of-conduct/", "text": "Code of conduct"}, {"url": "https://openedx.org/privacy-policy/", "text": "Privacy Policy"}, ], # Update link container classes "FOOTER_LINKS_CONTAINER_CLASSNAMES": "flex-wrap", # Update link styling "FOOTER_LINKS_CLASSNAMES": "text-dark font-weight-bold", }
