Provides read-only bindings to the Open Source Routing Machine - OSRM, a routing engine for OpenStreetMap data implementing high-performance algorithms for shortest paths in road networks.

Linux/OS X

See docs/api.md for extensive API documentation. You can find a simple example in example/server.js.

• Node.js v4.x
• Modern C++ runtime libraries supporting C++14

C++14 capable platforms include:

• Mac OS X >= 10.10
• Ubuntu Linux >= 16.04 or other Linux distributions with g++ >= 5 toolchain (>= GLIBCXX_3.4.20 from libstdc++)

An installation error like below indicates your system does not have a modern enough libstdc++/gcc-base toolchain:

Error: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version GLIBCXX_3.4.20 not found (required by /node_modules/osrm/lib/binding/osrm.node)

If you are running Ubuntu older than 16.04 you can easily upgrade your libstdc++ version like:

sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update -y
sudo apt-get install -y libstdc++-5-dev

addons:
  apt:
    sources: [ 'ubuntu-toolchain-r-test' ]
    packages: [ 'libstdc++-5-dev' ]

dependencies:
     pre:
         - sudo -E apt-add-repository -y "ppa:ubuntu-toolchain-r/test"
         - sudo -E apt-get upgrade -y
         - sudo -E apt-get -yq --no-install-suggests --no-install-recommends --force-yes install libstdc++-5-dev

By default, binaries are provided for:

• 64 bit OS X and 64 bit Linux
• Node v4.x

On those platforms no external dependencies are needed.

Just do:

npm install osrm

However other platforms will fall back to a source compile: see Source Build for details.

The node-osrm module consumes data processed by OSRM core.

This repository contains a Makefile that does this automatically:

• Downloads an OSM extract
• Runs osrm tools to prepare data

Just run:

make
make test

Once that is done then you can calculate routes in Javascript like:

You can build from source by using mason. Just go to your node-osrm folder and run:

make

This will download and build the current version of osrm-backend and set all needed variables.

Then you can test like

make test

To rebuild node-osrm after any source code changes to src/node_osrm.cpp simply type again:

make

If you wish to have a different version of osrm-backend build on the fly, change the osrm_release variable in package.json and rebuild:

make clean
make && make test

If you do wish to build node-osrm against an existing osrm-backend we assume it is installed and will be found by pkg-config.

To check if you installed it correctly the following command and verify the output:

which osrm-extract which osrm-contract which osrm-datastore pkg-config libosrm --variable=prefix

See the Project-OSRM wiki for details in how to build osrm-backend from source.

Now you can build node-osrm:

git clone https://github.com/Project-OSRM/node-osrm.git
cd node-osrm
mkdir build
cd build
cmake ..
make clean
make
make test

After setting up a Source Build you can make changes to the code and rebuild like any other cmake project:

cd build make

To rebuild using with a full re-configuration do:

make

If you want to see all the arguments sent to the compiler do:

make verbose

If you want to build in debug mode (-DDEBUG -O0) then do:

make debug

Run the tests like:

make test
