Unable to execute the sample NodeJS code

[mrkhan]

Hi,

I was trying to use the NodeJS Usage code mentioned in README.md but got an error

TypeError: Cannot read property 'open' of undefined
at Object. (\app.js:10:18)

`var geopackage = require('@ngageoint/geopackage')
, GeoPackageManager = geopackage.GeoPackageManager
, GeoPackageConnection = geopackage.GeoPackageConnection
, GeoPackageTileRetriever = geopackage.GeoPackageTileRetriever;

var filename = "./rivers.gpkg";

GeoPackageManager.open(filename, function(err, geoPackage) {`

it seems that GeoPackageManager is undefined.
is there any prerequisite before using geopackage-js ?

Just an observation in index.js file
in start of the file, its exporting other modules except the GeoPackageManager module

var proj4Defs = require('./lib/proj4Defs'); module.exports.proj4Defs = proj4Defs; module.exports.GeoPackageTileRetriever = GeoPackageTileRetriever; module.exports.GeoPackageConnection = GeoPackageConnection;

If I add module.exports.GeoPackageManager = GeoPackageManager; to it the sample code works fine.
So is the readme file incorrect or the code?

The README has not been updated to the new version of the code. I will update it to be correct. When you require var geopackage = require('@ngageoint/geopackage') you can now open a GeoPackage by calling geopackage.open(filename, callback);

If you want I can update it ?

Feel free to update and make a pull request. Thank you for your help.

How can we retrieve the content of geom, in other words how can we retrieve coordinates (long,lat) of a point using JavaScript from Geo-package?
