Beginner question

[Antonio Canela]

Hi, I'm trying to use locomotive to connect to a redis database. I would like to know if it's necessary to use express to do so or not. If true, how could I do something similar to this with locomotive:

app.get('/data.json', function(req, res){

 res.header("Access-Control-Allow-Origin", "*");

 datapoints.updateRT();

 valores=[ {"aData": datapoints.data}] 

 res.contentType('application/json');

 res.send(JSON.stringify(valores[0]));

});

I understand the app variable would be either locomotive or express.

Thank you very much in advance and sorry for my ignorance with this tech.
