How to create config node in node-red

natamongkol · 31 March 2023 06:55

I try create config node like this but it's show only text box no config, I want projectid to be a config node, I tried following many nodes with config node but it didn't work for me, How to fix it?

graphql_query.js

module.exports = function(RED) {
    function netpie_graphql_query(nodeConfig) {
        RED.nodes.createNode(this,nodeConfig);
        var node = this;
        node.on('input', function(msg) {
            var gqlquery = nodeConfig.gqlquery;

            nodeConfig.projectid = RED.nodes.getNode(nodeConfig.projectid).projectid;

            const axios = require('axios');
            let data = JSON.stringify({
            query: gqlquery,
            variables: {}
            });

            let axiosConfig = {
            method: 'post',
            maxBodyLength: Infinity,
            url: 'http://gqlv2.aaaaa.io/',
            headers: { 
                'Authorization': 'bearer '+auth.token, 
                'Content-Type': 'application/json'
            },
            data : data
            };

            axios.request(axiosConfig)
            .then((response) => {
            data = (JSON.stringify(response.data));
            msg.payload = data;
            node.send(msg);
            })
            .catch((error) => {
            //console.log(error);
            this.error("Request failed with status code 400, please check your schema");
            });
        });
    }
    RED.nodes.registerType("netpie_graphql_query",netpie_graphql_query);
}

but projectid is not config node

marcus-j-davies · 31 March 2023 08:05

Hi @natamongkol - Welcome to the forums.

I can't help notice this.

 return this.name || this.("projectid");

Should it be

 return this.name || this.projectid

Its to early in the morning for me to know if this.("projectid") is valid syntax.

Also, I don't think its invalid to do, but be careful naming config entries to a name that represents its own type name

RED.nodes.registerType('projectid',{})
projectid: {value:""}

I cant see anything else that would be a problem - but again its early

natamongkol · 31 March 2023 08:10

now i fix it but not working

return this.name || this.projectid;

marcus-j-davies · 31 March 2023 08:17

I would rename the config entry in your config node also.

From

 defaults: {
   name: {value:""},
   projectid: {value:""}
},

To

 defaults: {
   name: {value:""},
   id: {value:""}
},

If you think about the module its self.

module.exports = function (RED) {

  function projectid(nodeConfig) {
          RED.nodes.createNode(this,nodeConfig);
          this.name = nodeConfig.name;
  
           /* This could be causing a problem, as it maybe re-evaluating its self  */
          this.projectid = nodeConfig.projectid;
      }
      RED.nodes.registerType("projectid",projectid);
}

again, I'm not sure, it just sticks out at me, if trying it, ensure to rename references to it also

natamongkol · 31 March 2023 08:29

i try it but not work I've been stuck with this problem for 2 days now. I don't know how to fix this problem. I tried another node example using config node and tried to follow but it didn't work.

marcus-j-davies · 31 March 2023 08:40

Anything in the start up logs that might lend a clue, can you paste them here?
assuming you are using a ~recent Node RED version?

unless my eyes are giving up on me - other than the points I made, I cant see anything else.

knolleary · 31 March 2023 08:43

Noooo! id is a reserved property name.

marcus-j-davies · 31 March 2023 08:49

Uuhhh

id was probably not the best choice in my example

Completely forgot about that gem!

knolleary · 31 March 2023 08:55

I have just copied all of the provided files to my local node-red instance and:

fixed the return this.name || this.("projectid"); line to be this.projectid
added the missing <script> tag at the start of both HTML files
added the missing module.exports = function(RED) { line at the start of graphql_query_config.js

(The last two I assume were copy/paste errors when sharing the code rather than actually missing in your files)

With that done, it works as expected:

What version of Node-RED are you using? Are you fully restarting Node-RED (the runtime, not just reloading the editor) after making changes to the files?

One other recommendation is given you are defining one type as netpie_graphql_query I would not use projectid as the type for your config node - it is too generic. I suggest changing it to netpie_graphql_projectid or something a bit more specific.

natamongkol · 31 March 2023 09:09

Node-RED version: v3.0.2, I restart node-red every time I modify the node file, Can you please check if all this is correct?

const auth = require('../../../../dashboard/module/auth');

            const axios = require('axios');

i try this but not work

knolleary · 31 March 2023 09:17

I had to strip out the require and the input message handling code in your .js file, but with rest of it as you provide it works:

natamongkol · 31 March 2023 09:17

i don't know why don't work for me but work for you

knolleary · 31 March 2023 09:26

In the browser's javascript console, can you run:

RED.nodes.getType('projectid')

and share the output?

natamongkol · 31 March 2023 09:32

knolleary · 31 March 2023 09:35

Have you run that in a window with the Node-RED editor open?

natamongkol · 31 March 2023 09:36

yes i open node-red tab and run RED.nodes.getType('projectid')

knolleary · 31 March 2023 09:36

Then I really don't understand... if you were in a window with the Node-RED editor loaded, then RED would definitely be defined.

natamongkol · 31 March 2023 09:38

Should I also write the package.json file?

knolleary · 31 March 2023 09:40

Please show me a full screenshot of the browser window, with the node-red editor open, and the console with that error in

natamongkol · 31 March 2023 09:46

it's node-red in Flowengine
