Opta Router Boot

Sample VRP Application using Kotlin + Optaplanner + Graphhopper + Spring Boot + Websockets

This sample application uses the belgium map to calculate distances between points. The map can be found on this link. Download it and point the Env GRAPH_OSM_PATH to it's path, in order to run the application. The GRAPH_OSM_LOCATION Env must point to a temporary folder, in order to Graphhopper folder.

Both Envs can be customized on the application.yml file.

Run in development mode

This project is divided in 2 sub modules:

Server

To run the server module, run on server folder:

gradle bootRun

This command will run a Spring Boot application on port 8080.

Client

To run the client module, make sure you have node and yarn installed on your system, then run on client folder:

yarn serve

Point your browser to http://localhost:3000. This module will run on port 3000, but will proxy remote calls to port 8080.

Both Modules

Gradle can run both modules together

gradle bootRun -parallel

This task will run both modules on port 3000 and 8080.

Build assembled jar

To build a jar that contains both server and client modules assembled on the same app. Just run the task on the root folder:

gradle assembleServerAndClient

This will generate a jar named app.jar on the build folder. To run the generated app, then run GRAPH_OSM_PATH=<path_to_osm_map> GRAPH_OSM_LOCATION=<path_to_graphhopper_folder> java -jar app.jar.

Docker

A full packaged docker image (with belgium map) can be found at Dockerhub. To run the opta-router image:

docker run -p 8080:8080 pintowar/opta-router

Point your browser to http://localhost:8080.
