Proj4js ported for Node.js without the asynchronous definition loading.
npm install proj4nodeSynchronous Proj4js slimmed down for Node.js
Convert a WGS884 coordinate to SWEREF99 TM.
``javascript
var proj4node = require('proj4node'),
sweref = new proj4node.Proj('+proj=utm +zone=33 +ellps=GRS80 +towgs84=0,0,0,0,0,0,0 +units=m +no_defs'),
p = proj4node.transform(proj4node.WGS84, sweref, new proj4node.Point(11.901, 57.689));
console.log(p);
`
`
$ git clone https://github.com/icetan/proj4node.git
$ cd proj4node
$ ./connect-proj4js-repo.sh
Then read instructions from output.
Important to note, I have only removed functionality from the original Proj4js
project. All the hard stuff (algorithms and parsing) is solely thanks to the
authors of Proj4js.
