Example

const fs = require('fs');
const NetCDFReader = require('netcdfjs');

// http://www.unidata.ucar.edu/software/netcdf/examples/files.html
const data = fs.readFileSync('madis-sao.nc');

var reader = new NetCDFReader(data); // read the header
reader.getDataVariable('wmoId'); // go to offset and read it

Example II: Load from URL (does not require node)

// First load the netcdfjs library as normal : <script src='./dist/netcdfjs.js'></script>

var urlpath =  "http://www.unidata.ucar.edu/software/netcdf/examples/madis-sao.nc"
var reader;

var oReq = new XMLHttpRequest();
oReq.open("GET", urlpath, true);
oReq.responseType = "blob";

oReq.onload = function(oEvent) {
  var blob = oReq.response;
  reader_url = new FileReader();
  
  reader_url.onload = function(e) {
       reader = new netcdfjs(this.result);
      }
      
  reader_url.readAsArrayBuffer(blob);
};
oReq.send(); //start process



reader.getDataVariable('wmoId'); // go to offset and read it
