I am learning node.js (and express framework) & here is a basic newbie question about redis & node.js. How to pass redis data to templates? What should I correct in my script, so I could display the value of teststring in a template?
app.get('/', function(req, res){
res.render('index', {
test: redisclient.get("teststring"),
});
});
Thanks in advance!
Since node.js modules (including the one for redis) tends to be non-blocking and asynchronous, they are returning results in callbacks. Try it this way (I also recommend to read this article regarding asynchronous code and callbacks):
app.get('/', function(req, res) {
redisclient.get("teststring", function(error, response) {
if(response) {
res.render('index', {
test: response,
});
} else {
res.render('index', {
test: error,
});
}
});
});
