RhoConnect provides a simple redis interface for saving/retrieving arbitrary data. This is useful if you want to save data in your application to be used later (i.e. in an async job or a subsequent source adapter execution). As with the other JavaScript methods execution is asynchronous, so be sure to call resp.send() or your method will hang.
To create a Store object that you can use in your model:
var rc = require('rhoconnect_helpers'); var Store = rc.Store;
Retrieve a simple value from redis.
var value = ''; resp.params = 'hello'; Store.getValue(resp, function(resp){ value = resp.result; // value is now 'world' resp.send(resp.result); });
Add a simple value to redis. The first array item is the key, the second is the value.
resp.params = ['hello', 'world'] Store.putValue(resp, function(resp){ resp.send(true); });
Retrieve an array or hash from redis.
// assuming 'foo' contains {'1': {'name': 'iPhone'}} resp.params = 'foo'; Store.getData(resp,function(resp){ resp.send(resp.result); // returns {'1': {'name': 'iPhone'}} });
Add an array or hash to redis. The key and data are contained in the resp.params object.
resp.params = [ 'foo', { '1': {'name': 'iPhone'} } ] Store.putData(resp,function(resp){ resp.send(resp.result); }); // 'foo' key now contains { '1': {'name': 'iPhone'} }
