This application downloads all rent ads for Stockholm from Blocket.se, and shows them on a map. It is written as a node.js REST application and uses a Neo4j database for storing all the information.

To run it, simply clone the repository and type:

npm install
npm start -- --initialize

In this way the application is listening on http://127.0.0.1:3000 and views something like this:

The base route /blocket/map expects some parameters for filtering the results.

• the metro line that can be one in red, green, blue, or the name of a line like T10, T11, T13, T14, T17, T18, T19. The value any can be used to get any line or color.
• the distance in km from the closest metro station. It can also be a decimal like 0.4. If the distance is 0, no filtering is done, i.e. all ads with some coordinates are returned.
• the maximum price, in SEK/month. If 0 is passed, no filtering is done on the price.
• the maximum age of the ads, in days. If 0 is passed no filtering is done on the age.

I usually use something like http://127.0.0.1:3000/blocket/map/any/1/10000/0

The application also needs a Neo4j database up and running, that can be configuered through config.js.
