I'm perpetually curious about property data, and I want to learn about node. So I'm using node to scrape, transform, organize, and store property data. Fun, right?
You'll need a mongodb install somewhere. I just do it on my Ubuntu localhost following the usual documentation
Then it should just be npm install.
If you dare scrape and store property data, say ./sfgate.js --help. You
may just want to grab the first hundred pages or so to fool around.
