gmaps-url-signer

This is a node.js URL signer for Google Maps API Web Services. It simply packages Google's documentation and example code provided here into a Node module.

URL signing is used in the Static Maps, Directions, Geocode API, and more.

Here's an example of how you can use this library:

const urlSigner = require('gmaps-url-signer');

const key = 'my_google_api_key';
const secret = 'my_static_maps_secret';
const domain = 'http://maps.googleapis.com';

// Path to your static map
let path = '/maps/api/staticmap?zoom=2&scale=1&size=350x250&maptype=terrain&format=png&visual_refresh=true';
path += `&key=${key}`;

console.log('Full signed URL:');
console.log(domain + urlSigner.sign(path, secret));
