#Add your service credentials

Create a new file on the root of keylines-demo and call it creds.json
Edit the file and add your service credentials json

{
  "apiURL" : "<service apiURL>/g",
  "username" : "<Your username >",
  "password" : "<Your password>",
}

#Loading the data This code doesn't load data into the service yet (will do it soon). But you can easily add the data using bulkload API. Alternatively, you can just load the sample data from the service UI on Bluemix. Check the documentation for more details https://ibm-graph-docs.ng.bluemix.net/examples.html#node.js

Here's a sample of loading a graphml file

var bulkUploadOpts = {
    method: 'POST',
    headers: {'Authorization': sessionToken},
    uri: apiURL + '/bulkload/graphml',
    formData: {
      'graphml': fs.createReadStream(__dirname +  
          '/../public/sample_graphml.xml'),
      'type': 'application/xml'
    }
};
request(bulkUploadOpts).then(function (body){
    console.log('Our file was uploaded and the result was : ' +
        JSON.stringify(body.result.data[0]));
});
