通过Express从Node.js获取数据

Question

I have a server with Node.js and I use Express to build a web app. My server is already able to get an array from a database using a function (rss_interrogDB). Now I want to use this array to display a list in the html page. But I must be missing something...

On the server-side my code is:

app.get('/', function(req, res) { 
rss_interrogDB(function() {
// don't konw what to add here
});

On the html page the code is:

$.get('/', {}, function(data){
// not sure it is the right code
console.log(data);
// then the code to create a list from the array (no pb with that)
});

Thank you for your help!

Answer 1

Assuming your DB gives you an array of data, add something like this to your server code:

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

    rss_interrogDB(function(serverData) {
        res.send(serverData);             
    });

});

You could manipulate the serverData object and build one that is more suitable for the client before you send it back, but that depends on what you want to do.
