Cloudflare Adds Security.txt Setup Wizard
Cloudflare has launched a setup wizard allowing users to easily create and manage a security.txt file for vulnerability disclosure on their websites.
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.

See docs/api.md for extensive API documentation. You can find a simple example in example/server.js
.
C++11 capable platforms include:
An installation error like below indicates your system does not have a modern enough g++ toolchain:
Error: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.17' not found (required by /node_modules/osrm/lib/binding/osrm.node)
If you are running Ubuntu older than 14.04 you can easily upgrade your g++ toolchain like:
sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get install g++-4.8
By default, binaries are provided for:
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:
Just run:
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 not wish to build node-osrm against an existing osrm-backend that you have on your system you will need:
make -C test/data
inside the osrm-backend
directorySee Project-OSRM wiki for details.
Once Project-OSRM is built you should be able to run:
pkg-config libosrm --variable=prefix
Which should return the path to where you installed Project-OSRM.
Now you can build node-osrm
:
git clone https://github.com/Project-OSRM/node-osrm.git
cd node-osrm
npm install --build-from-source
To run the tests against your local osrm-backend's data you will need to
set the OSRM_DATA_PATH
variable:
export OSRM_DATA_PATH=/path/to/osrm-backend/test/data
Then you can run npm test
.
To recap, here is a full example of building against an osrm-backend that is cloned beside node-osrm but installed into a custom location:
export PATH=/opt/osrm/bin:${PATH}
export PKG_CONFIG_PATH=/opt/osrm/lib/pkgconfig
pkg-config libosrm --variable=prefix
# if boost headers are in a custom location give a hint about that
# here we assume the are in `/opt/boost`
export CXXFLAGS="-I/opt/boost/include"
npm install --build-from-source
# build the osrm-backend test data
make -C ../osrm-backend/test/data
export OSRM_DATA_PATH=../osrm-backend/test/data
npm test
After setting up a Source Build you can make changes to the code and rebuild like:
npm install --build-from-source
But that will trigger a full re-configure if any changes occurred to dependencies.
However you can optionally use the Makefile which simplifies some common needs.
To rebuild using cached data:
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
Under the hood this uses node-pre-gyp (which itself used node-gyp) to compile the source code.
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 265 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.
