Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

|Build Status| |Codecov| |npm_version| |npm_downloads| |license| |semantic-release|

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``
  1. 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>`_.
  1. Install npm dependencies:
``cd frontend-component-footer && npm ci``
  1. 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", }
