Development

Prerequesties

1. Java 8
2. Scala 2.12
3. SBT
4. Elm 0.18
5. elm-css
6. Docker
7. Postgres
8. Osmosis
9. PostGIS
10. pgrouting
11. osm2pgrouting

To setup database locally:

# Assuming you have an .osm.pbf file from Geofabrik
# Use osmosis to select specific area
osmosis --read-pbf ./ontario-latest.osm.pbf --bounding-box top=43.753963 bottom=43.561912 left=-79.632868 right=-79.194903 --write-xml toronto.osm
# or just keep the entire area
osmosis --read-pbf ./ontario-latest.osm.pbf --write-xml ontario-latest.osm
# create maps database with trifecta user
createuser -s trifecta
createdb maps --user trifecta
# Setup postgis and pgrouting in the db
psql maps --user trifecta
> create extension postgis;
> create extension pgrouting;
# import osm data into db
osm2pgrouting --f toronto.osm --conf /usr/share/osm2pgrouting/mapconfig_for_bicycles.xml --dbname maps --clean
# note: on macOS if osm2pgrouting was installed with Homebrew the path for the config is /usr/local/Cellar/osm2pgrouting/2.2.0_2/share/osm2pgrouting/mapconfig_for_bicycles.xml

To compile server components:

sbt api/compile

To compile web assets:

cd web/
elm make src/Main.elm --output=public/javascripts/main.js
elm-css src/Stylesheets.elm --output=public/stylesheets/main.css

To run server locally:

You need the following environment variables

# if running osrm as stated below this can be set to http://localhost:5000
OSRM_URI
# at this point in time strava is the only auth service and as such strava client identifiers are required
STRAVA_CLIENT_ID
STRAVA_CLIENT_SECRET
# needs to exist for the application to run, but can be any string if mailing list signup is not required
MAILCHIMP_TOKEN

Note the first time the server is run it will setup the database. This however has one caveat at the moment as it does not add the "temporary" table beta_user_whitelist.

psql maps --user trifecta
> create table beta_user_whitelist (email text);
> insert into beta_user_whitelist values ('your strava email address');

Run the server

sbt "api/run -Dhttp.port=9001"
sbt web/run

To run routing locally:

# Get OSM data
cd resources/osrm && mkdir maps && cd maps
curl -LO http://download.geofabrik.de/north-america/canada/ontario-latest.osm.pbf && cd ..
# Prepare data for routing
docker run -t -v $(pwd)/maps:/data -v $(pwd)/profiles:/opt osrm/osrm-backend osrm-extract -p /opt/bicycle.lua /data/ontario-latest.osm.pbf
docker run -t -v $(pwd)/maps:/data osrm/osrm-backend osrm-contract /data/ontario-latest.osrm
# Run routing server
docker run -t -i -p 5000:5000 -v $(pwd)/maps:/data osrm/osrm-backend osrm-routed /data/ontario-latest.osrm

To run tileserver locally:

# find docker ip address (172.16.123.1 on macOS)
sudo ifconfig lo0 alias 172.16.123.1 # macOS only

Update postgres to trust connections from the above address. Open your pg_hba.conf and add host all all 172.16.123.1/32 trust. Then start the docker container.

docker run -e TREX_DATASOURCE_URL=postgresql://trifecta@172.16.123.1/maps -p 8080:8080 --name trex kiambogo/roadquality_tileserver:0.2.2
