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.
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 ~/code/node-mongo-postal/local.config.js
This test searches for the 10 closest postal objects within a 4 mile radius of zipcode 94133:
node test/test-find-query.js -c ~/code/node-mongo-postal/local.config.js -z 94133 -m 10 -r 4Output:
