Greenlight Application

GitHub Repository | npmjs package | Unpkg CDN | Greenlight Bundle | Project documentation

Note: This project depends on the DCC infrastructure of the Austrian Government. Since the DCC infrastructure is no longer available since June 2023, this project is no longer actively maintained.

Creates an entrance ticket and imports your evidence of a low epidemiological risk on the working device to validate it for admission even before attending a course or exam. The ticket then enables you to access the university premises quickly and efficiently.

Prerequisites

• You need the API server running
• You need the DbpRelayGreenlightBundle to create permits for the Covid19 certificate evaluation process
• For more information please visit the Greenlight project documentation

Local development

# get the source
git clone git@github.com:digital-blueprint/greenlight-frontend.git
cd greenlight
git submodule update --init

# install dependencies
npm install

# constantly build dist/bundle.js and run a local web-server on port 8001 
npm run watch

# constantly build dist/bundle.js and run a local web-server on port 8001 using a custom assets directory assets_custom/
npm run watch-custom

# run tests
npm test

Jump to https://localhost:8001, and you should get a Single Sign On login page.

To enable building with custom assets, you need to provide your custom assets in the directory assets_custom/greenlight-app/assets/. If you want to, you can also change this path in the file rollup.config.js. For more information, please visit the dbp handbook page on custom assets.

Using this app as pre-built package

Install app

If you want to install the dbp greenlight app in a new folder greenlight-app you can call:

npx @digital-blueprint/cli@latest install-app greenlight greenlight-app /

Warning: There may be issues when you run these commands as root user, best use a non-root user, like www-data. To do this you can for example open a shell with runuser -u www-data -- bash.

Afterwards you can point your Apache web-server to greenlight-app/public.

Make sure you are allowing .htaccess files in your Apache configuration.

Also make sure to add all of your resources you are using (like your API and Keycloak servers) to the Content-Security-Policy in your greenlight-app/public/.htaccess, so the browser allows access to those sites.

You can also use this app directly from the Unpkg CDN for example like this: dbp-greenlight/index.html

Note that you will need a Keycloak server along with a client id for the domain you are running this html on.

Update app

If you want to update the dbp greenlight app in the current folder you can call:

npx @digital-blueprint/cli@latest update-app greenlight

Warning: After the update the trust data has to be restored, see below.

Warning: There may be issues when you run these commands as root user, best use a non-root user, like www-data. To do this you can for example open a shell with runuser -u www-data -- bash.

Cron job for Updating the Trust Data

The app depends on the official trust list, value sets and business rules which are provided via https://github.com/Federal-Ministry-of-Health-AT/green-pass-overview

In addition it depends on a set of business rules which are maintained at https://github.com/digital-blueprint/dcc-at-rule-sets

Both data sets need to be updated regularly via a cron job.

0    *    *    *    *     /<my-path>/greenlight-app/public/app/update.sh TUGRAZ

The first argument passed to update.sh defines the rule set which should be downloaded. The script depends on curl being installed.

You will find the certificates downloaded in /<my-path>/greenlight-app/public/app/local/@digital-blueprint/greenlight-app/dgc-trust/prod.

NOTE: Failing to update the data will result in signatures expiring after 2 days which breaks the core functionality of the app.

Activities

This app has the following activities:

• dbp-acquire-3g-ticket
• dbp-show-active-tickets
• dbp-show-reference-ticket

You can find the documentation of these activities in the greenlight activities documentation.

    requested-login-status
    analytics-event
>
</dbp-greenlight>
