Combatting Alert Fatigue by Prioritizing Malicious Intent
In 2023, data breaches surged 78% from zero-day and supply chain attacks, but developers are still buried under alerts that are unable to prevent these threats.
Routing engine for OpenStreetMap data implementing high-performance algorithms for shortest paths in road networks.
Provides bindings to the Open Source Routing Machine - OSRM.
By default, binaries are provided and no external dependencies or compile is needed.
Just do:
npm install osrm
We currently provide binaries for 64 bit OS X and 64 bit Linux. Running npm install
on other
platforms will fall back to a source compile (see Developing
below for build details).
First you need to download some OSM data and process it with OSRM.
Next you need to create an OSRM config (ini) file that references the OSRM prepared routing data.
This repository contains a Makefile to automatically do this, assuming you have OSRM installed.
Just run:
make berlin-latest.osrm.hsgr
Next, since we want to use node-osrm locally, do:
export NODE_PATH=lib
Once that is done then you can calculate routes in Javascript like:
var osrm = require('osrm')
var opts = new osrm.Options("./test/data/berlin.ini");
var engine = new osrm.Engine(opts);
var query = new osrm.Query({coordinates: [[52.519930,13.438640], [52.513191,13.415852]]});
var sync_result = engine.run(query);
JSON.parse(engine.run(query));

OSRM develop
branch, cloned from github.
OSRM build with -DWITH_TOOLS=1
so that libOSRM
is created
Lua, luabind, and stxxl headers
Boost >= 1.50 or Luabind headers patched as in https://github.com/DennisOSRM/Project-OSRM/issues/465#issuecomment-9133539 (note: it is possible to patch the luabind headers that are installed by apt)
If you use luajit then you may need to put the luajit headers on the compile flags like:
export CXXFLAGS="-I/usr/include/luajit-2.0/"
To build with OS X Mavericks you need to ensure the bindings link to libc++
. An easy way to do this is to set:
export CXXFLAGS=-mmacosx-version-min=10.9
before building node-osrm
.
To build the bindings you need to first build and install the develop
branch of Project-OSRM
:
# grab develop branch
git clone -b develop https://github.com/DennisOSRM/Project-OSRM.git
cd Project-OSRM
mkdir build;
cd build;
cmake ../ -DWITH_TOOLS=1
make
sudo make install
NOTE: If you hit problems building Project-OSRM see the wiki for details.
Then build node-osrm
against Project-OSRM
installed in /usr/local
:
git clone https://github.com/DennisOSRM/node-osrm.git
cd node-osrm
npm install
Run the tests like:
make test
FAQs
The Open Source Routing Machine is a high performance routing engine written in C++14 designed to run on OpenStreetMap data.
The npm package osrm receives a total of 277 weekly downloads. As such, osrm popularity was classified as not popular.
We found that osrm demonstrated a not healthy version release cadence and project activity because the last version was released a year ago. It has 21 open source maintainers collaborating on the project.
