datastore-keyutil

A utility to make dealing with @google-cloud/datastore keys little more pleasant.

Usage

var Datastore = require('@google-cloud/datastore');
var ds = new Datastore(/* init options */);

var KeyUtil = require('datastore-keyutil').KeyUtil;

var options = {
    // boolean (default: false) - exposes instance as ds.keyUtil,
    embed: true, 
    
    // function (default: throws BadKeyError with message) - function to call on invalid data.    
    errorFn: function(message, data) {
        console.error(message, data);
        throw new Error(message);
    }
}

var ku = new KeyUtil(ds, options);

ds.query('kind')
  .select('__key__')
  .run()
  .then(function (data) {
      var entities = data[0];

      var keysArray = ku.mapToKeys(entities);

      var uidsArray = ku.mapToBase64UIDs(entities);
  });

See here for an exhaustive list of KeyUtil functions.

Running the tests

To run the tests, you'll need to run a local Datastore emulator, from the Google Cloud SDK.

Then, run npm test
