frontend-component-header

Purpose

A generic header for Open edX micro-frontend applications.

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.

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.

Environment Variables

LMS_BASE_URL - The URL of the LMS of your Open edX instance.
LOGOUT_URL - The URL of the API endpoint which performs a user logout.
LOGIN_URL - The URL of the login page where a user can sign into their account.
SITE_NAME - The user-facing name of the site, used as alt text on the logo in the header. Defaults to "localhost" in development.
LOGO_URL - The URL of the site's logo. This logo is displayed in the header.
ORDER_HISTORY_URL - The URL of the order history page.
ACCOUNT_PROFILE_URL - The URL of the account profile page.
ACCOUNT_SETTINGS_URL - The URL of the account settings page.
AUTHN_MINIMAL_HEADER - A boolean flag which hides the main menu, user menu, and logged-out menu items when truthy. This is intended to be used in micro-frontends like frontend-app-authentication in which these menus are considered distractions from the user's task.
ENABLE_HEADER_LANG_SELECTOR - A boolean to enable the language selector in the header component.
SITE_SUPPORTED_LANGUAGES - A list with all the languages to display in the selector.
LOGO_URL_MOBILE - The URL of the site's logo for mobile. This logo is displayed in the header.

Installation

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

npm i --save @edx/frontend-component-header

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

Cloning and Startup

1. Clone your new repo:

  ``git clone https://github.com/openedx/frontend-component-header.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-header && npm ci``

4. Start the dev server:

  ``npm start``

Usage

This library has the following exports:

(default): The header as a React component.
messages: Internationalization messages suitable for use with @edx/frontend-platform/i18n
dist/index.scss: A SASS file which contains style information for the component. It should be imported into the micro-frontend's own SCSS file.

Examples

Development

Install dependencies:

npm ci

Start the development server:

npm start

Build a production distribution:
