A generic web-app for finding the nearest locations of a single type of utility (e.g. toilets, recycling stations) on OpenStreetmap. The current customization uses playgrounds as an example.
You need the following tools installed on your system:
- NodeJS and NPM. You can check if you have NodeJS by running
node -vin your terminal. Otherwise go to nodejs.org to install the newest version. NPM is part of the NodeJS installation
- Ruby and Sass. You can also check for ruby with
ruby -v. In addition to ruby you need Sass which you can install via
gem install sassin your terminal.
If you have installed those dependencies go to the project folder and
npm install to install all dependencies of the app.
Sometimes you have to install some of the packages manually.
The Gulp taskrunner is used for creating compiling sass, concatenating js and
creating a deployable version.
After all dependencies are installed you can run
gulp serve to run the app locally.
The Gulp taskrunner automatically starts up a local server. When compiling Gulp
automatically checks for compliance with the included JSHint and JSCS rules.
The following tutorial can also help you understand the purpose and uses of Gulp and Browserify:

To get a deployable version of the app run
gulp while on the master branch.
The contents of the
/dist folder are then ready for deployment. This version can
theoretically be hosted on any webserver.
GitHub Pages uses the gh-pages branch as a source for the files that are hosted.
This means to update the version running on GitHub Pages just replace the contents
of the gh-pages branch with the contents of the
Our code uses the MV* framework Ampersand.js for structuring.
Our general structure is derived from the short book
app.js is the main entry point of our application and initializes required objects.
app-controller.js manages the state changes in the app.
user-state.js is instantiated as a singleton that saves all properties of the user.
map-node-collection.js define the classes that handle the
results from Nominatim/Overpass.
We use leaflet.js for showing and interacting with the map. Only our
map-view.js and the
leaflet-config.js interact with this library.
In order to change the target utility of the FinderApp you just have to a few small things.
Title and search query can be changed in the config object in the
We use the Nominatim API of OpenStreetMap.
Nominatim is able to understand special keywords for search in OSM.
A list of available keywords can be found here.
Additionally, you probably need to change the logo and maybe colours to suit your
target utility. The logo url can be found in the index.html file and
colours can be changed in the
If you also want to host your version on GitHub Pages you can fork the project.
Make sure you have a gh-pages branch with the updated contents of the
