Hi,  
I tried config node following [Configuration nodes : Node-RED (nodered.org)](https://nodered.org/docs/creating-nodes/config-nodes), I wrote remote-server.html

// remote-server.html

```auto
<script type="text/javascript">
    RED.nodes.registerType('remote-server',{
        category: 'config',
        defaults: {
            host: {value:"localhost",required:true},
            port: {value:1234,required:true,validate:RED.validators.number()},
        },
        label: function() {
            return this.host+":"+this.port;
        }
    });
</script>

<script type="text/html" data-template-name="remote-server">
    <div class="form-row">
        <label for="node-config-input-host"><i class="fa fa-bookmark"></i> Host</label>
        <input type="text" id="node-config-input-host">
    </div>
    <div class="form-row">
        <label for="node-config-input-port"><i class="fa fa-bookmark"></i> Port</label>
        <input type="text" id="node-config-input-port">
    </div>
</script>

```

and remote-server.js

```auto
module.exports = function(RED) {
    function RemoteServerNode(n) {
        RED.nodes.createNode(this,n);
        this.host = n.host;
        this.port = n.port;
    }
    RED.nodes.registerType("remote-server",RemoteServerNode);
}

```

and I want to quote the remote server node in test node, here are the .js and .html file:  
test.html

```auto
<script type="text/javascript">
    RED.nodes.registerType('test',{
        category: 'function',
        color: '#a6bbcf',
        defaults: {
            server: {value:"", type:"remote-server"}
        },
        inputs: 1,
        outputs: 1,
        icon: "file.svg",
        label: function() {
            return this.name||"test";
        }
</script>

<script type="text/html" data-template-name="test">
     <div class="form-row">
         <label for="node-input-server"><i class="fa fa-tag"></i> Server</label>
         <input type="text" id="node-input-server">
     </div>
</script>

<script type="text/html" data-help-name="test">
    <p>A simple node for configuring
</script>

```

test.js

```auto
module.exports = function(RED) {
    function TestNode(config) {
        RED.nodes.createNode(this,config);
        var node = this;
       
        this.server = RED.nodes.getNode(config.server);
        node.log(this.server);
        node.log("host =");
        node.log(this.server.host);
        node.log("port =");
        node.log(this.server.port);
        node.on('input', function(msg) {
            node.send(msg);
        });
    }
 RED.nodes.registerType("test",TestNode);

```

When I started node-red, it showed that this.server is null. How can i use the config node ? Thanks.

Hello @abu !  
Welcome to this forum!

As the flow is still in the process of being created, your config node might not exist so far.  
Have you tried to get it in `node.on('input', ... )`? There it should be setup & present.

</div>

I tried in node.on, here is the code:

```auto
 node.on('input', function(msg) {
            this.server = RED.nodes.getNode(config.server);
            node.log(this.server);
            if( this.server )
            {
                node.log("host =");
                node.log(this.server.host);
                node.log("port =");
                node.log(this.server.port);
            }

            node.send(msg);
        });

```

and this.server is still null. And in the edit page, the input box of server has no select values as a down list in the box.

The runtime does try to ensure all config nodes are started before any flow nodes are created.

@abu have to logged the value of `config.server` to ensure it's actually set to the id of the config node you expect?

Maybe the code pasted but it's `</label>`

Hi GogoVega,  
The \</la has been changed to `</lable>`, the input box of server has no select values, and config.server is empty.

You reversed the place of the second `l` with `e` =\> `label` instead of `lable`  
Don't forget to reload/refresh your browser after restarting NR

Hi GogoVega,  
Sorry for that, it is a spelled fault. In the code, it is label, not lable. and thanks for pointing out that.

No worries,  
I don't see anything wrong. Have you refreshed your browser?

This must be done after each restart of NR in order to load the new code into the browser

I refreshed the browser, and and node.log(config.server) is empty.

The problem comes from the input - is it formatted correctly (select input with options)?

</div>

I think that the select options of server are from node remote-server, because i quote it as:

```auto
defaults: {
            server: {value:"", type:"remote-server"}
        },

```

Is that correct ?

Yes, the input box of server should have select options, but now the input box has no select options at all, and I can not figure out why.

Do you have to declare config nodes in package.json like other nodes? Can't remember.

Yes, same way

Can you try `RED.nodes.getType("remote-server")` in the browser console

I added `RED.nodes.getType("remote-server")` to test.js, it showed:  
 ![1704761758221](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/8/a/8a19e4c3b6135bec2298a77ec3ef78c3c65dc029.png)

and I added a function node in browser console, like

 ![17047620613288](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/7/a/7a8e15f6bdfc3f852a16c0dad9f9884841086cb5.png)

after clicking the inject node, the browser console showed

function : (error)  
"TypeError: Cannot read properties of undefined (reading 'getType')"

and the function node just like this:

```auto
msg.payload = RED.nodes.getType("remote-server");
return msg;

```

it seems that `RED.nodes.getType("remote-server")` is not defined in node-red.

Hi,  
I added `remote-server` to package.json, and fixed the issue. Thanks for your help.

I said in the browser console but regardless the goal was to check that your config node has been loaded.
