Configuration

I recommend creating a copy of config.js called local.config.js and adding it to your .gitignore so your MongoDB configuration settings do not get persisted in git.

Loading Postal Codes into MongoDB from the Command-Line

Saves postal code documents in MongoDB using geospatial indexes.

Example (be sure to npm install the dependencies listed under "NPM Dependencies" first):

node test/load-geonames.js --file ~/data/geonames/US/US.txt --config ./local.config.js

Querying Postal Codes by Source Zipcode and Radius

Command-Line

This test searches for the 10 closest postal objects within a 4 mile radius of zipcode 94133:

node test/test-find-query.js -c ./local.config.js -z 94133 -r 1
Using MongoDB settings in configuration file: ./local.config.js
