Can't send an array of Javascript objects in node.js

Question

I have the following code

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

console.log(posts);
res.send(posts);
res.send(200);
});

And i am using the following to get and return the array of js objects (posts is the array)

App.PostsRoute = Ember.Route.extend({
model: function(){
    return $.ajax({
        url : '/posts',
        type : 'GET',
        success : function(data){
            return data;
        }
    });
}
});

So when i populate the posts array with [ { body: "Hello" }, {body : "world" } ] , i get the following output in console :

Output of node console

Whereas in my app, the model is not rendered, moreover i can't see any response in chrome dev tools, these are some ss

Chrome SS

Response is Empty, not even {} . What is going wrong? I dont think there is anything with Ember , after all i can't see the response!

I think the problem occurs because you call res.send twice. Just comment this line:

res.send(200);

This line is not needed because Express automatically sets status code as 200 (or in some occasions - 304).

If you want to set your own status code, just write:

res.status(someCode);

as you can read here.

but will it work if use res.send(200) and res.json(obj) one after another?

@user206032 i believe not will not. but you can also write either res.json(200, obj);, or res.send(200, obj);

A few problems:

You need to JSON.stringify your object before you send it.

Try to use this instead of res.send:

res.writeHead(200, {'Content-Type': 'application/json'});
res.end(JSON.stringify(posts));

Where are you trying to return 'data'? You should have some callback function there, like this:
```
success:function(data) {
    handleData(data); 
}
```
