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.

.. _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 @edx/frontend-component-footer
This will make the component available to be imported into your application.
Cloning and Startup
.. code-block::
- Clone your new repo:
``git clone https://github.com/openedx/frontend-component-footer.git``
- 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.
