Backend

Webapp backend is a simple HTTP(s) service with endpoints for different tasks. Some endpoints require authentication. Authentication is implemented using HTTP-basic authentication and signed JWT-tokens.

Frontend

• re-frame Single Page Application
• material-ui components

Postgis database

Spatial PostGIS for master data storage.

Nginx

Web facing Nginx reverse proxy, ssl-termination.

Mapproxy

Mapproxy basemap proxy and cache.

ELK-stack

ELK (ElasticSearch, Logstash, Kibana) is used to provide webapp search funtionalities as well as data and monitoring information.

Old Lipas

All data flows also to old Lipas which exposes the data through Geoserver and legacy REST-Api.

REST-API

See Api-documentation here.

GeoServer

Geoserver publishing spatial data. See available layers here.

Dev-env setup

# Create env-file from template
cp .env.sample.sh .env.sh

Frontend

docker-compose run frontend-npm-deps
docker-compose run frontend-build

Apple Silicon considerations

Open Source Routing Machine currently has not an arm64 build. It is much faster than using the x86 image so consider building it yourself:

git clone https://github.com/Project-OSRM/osrm-backend.git
cd osrm-backend
docker build -t osrm-local --platform arm64 -f docker/Dockerfile . 

Then you need to replace every usage of osrm/osrm-backend image with osrm-local, for example:

sed -i '.backup' s|osrm/osrm-backend|osrm-local|g docker-compose.yml
sed -i '.backup' s|osrm/osrm-backend|osrm-local|g osrm/README.md    

Then see osrm/README.md to build the osrm files.
