hakancunier / vroom-express

Out of the box Node-express server to use VROOM as a web API.

Requirements

• Access to a routing engine (OSRM or OpenRouteService)
• VROOM

Setup

• Clone the repo

git clone https://github.com/VROOM-Project/vroom-express.git
cd vroom-express
git checkout v0.5.0

• Install dependencies using npm

npm install

Usage

Run the server using:

npm start

Health check should now return a 200 HTTP status code:

curl -w "%{http_code}" http://localhost:3000/health
200

Provided everything is fine with your VROOM and routing setup, you should now be able to run queries like:

curl --header "Content-Type:application/json" --data '{"vehicles":[{"id":0,"start":[2.3526,48.8604],"end":[2.3526,48.8604]}],"jobs":[{"id":0,"location":[2.3691,48.8532]},{"id":1,"location":[2.2911,48.8566]}],"options":{"g":true}}' http://localhost:3000

See the API documentation for input syntax.

Customization

Server side

Adjust config.yml to your needs.

Optionally set VROOM_ROUTER=<router>, router being osrm (default), libosrm or ors. Using the environment variable will override the config.yml router setting.

Client side

If override is set to true in config.yml, then the vroom command-line parameters -g, -t and -x can be set dynamically per request in order to add detailed route geometry and indicators, set the number of threads and exploration level.

Set values in the json payload via the options key:

"options": {
  "g": true,
  "t": 4,
  "x": 5
}
