DEMO/EXAMPLE mode

Problem this feature will solve

The laravel 8 default welcome page is too, basic.
There is no MySql integration by default.
There is no frontend scaffolding such as react by default.
Without programming it themselves, users cannot see how a Laravel 8 project works complete with MySQL integration, dummy data, migrations, and front end scaffolding such as react.

Background

Gitpod has default examples in the workspace dashboard however there is nothing that shows a complete project using a LAMP stack. Given that this starter project is more software than an example, Gitpod cannot use this project as is for one of their examples. If this repository could be showcased as an exmaple with a single URL then perhaps it could be used as an example by gitpod. Also users could really benefit from seeing how this starter project can be used, not to mention it can teach people how to work with Laravel and React if there is a good demo project that comes with the starter

Proposed Solution

Implement an example project that can be activating by passing in an environment variable in the url. See the Passing In Environment Variables section on the Gitpod website here.
add the variable EXAMPLE=
Where integer is the demo to be displayed (configured, installed)

Constraints and Assumptions

For now just support one example, EXAMPLE=1

EXAMPLE 1 - LAMP stack with:
laravel 8.x, MySql, phpMyAdmin, react frontend (react and react dom ^17.0.1), react-router-dom, github-changelog-generator

• use https://github.com/apolopena/q-and-a-challenge
• Just the files that need to be added to an existing vanilla gitpod-laravel8-starter project have been put here https://github.com/apolopena/QnA-demo-skeleton

The following works so write this into init-optional-scaffolding.sh

curl -LJO https://github.com/apolopena/QnA-demo-skeleton/archive/refs/tags/1.0.0.tar.gz
tar -xvzf QnA-demo-skeleton-1.0.0.tar.gz --strip-components=1
rm QnA-demo-skeleton-1.0.0.tar.gz
php artisan migrate
php artisan db:seed
yarn run mix
