using kibana 5.5.1. The aim is to make a variable through kibana.yml whose edits can be implemented without deleting and re-compiling the optimization folder. Below is the index.js

export default function (kibana) {  
return new kibana.Plugin({  
id:'my\_team\_plugin',  
uiExports: {  
docViews: ['plugins/my\_team\_plugin/team\_plugin']

```
	},
	config: function (Joi) {
		return Joi.object({
			enabled: Joi.boolean().default(true),
			tx: Joi.string(),});
			},
	});

```

}

Using this it seems to recognize this line in kibana.yml  
my\_team\_plugin.tx: xxxxxxxxxxx

after the Joi has been configured how can I call the variable in js files so that edits made to the config can be implemented without re-optimization? require('./../index.js') causes an error.

No need to include `index.js` to access configurations. On the server, configurations are available on the server object. For example, in the APM application, configurations are accessed on the server via [server.config()](https://github.com/elastic/kibana/blob/6.3/x-pack/plugins/apm/index.js#L29)

To access configurations on the client, you must first put them into [injectDefaultVars](https://github.com/elastic/kibana/blob/6.3/x-pack/plugins/apm/index.js#L31). Then, in the UI code you can access the variables via [chrome.getInjected](https://github.com/elastic/kibana/blob/6.3/src/core_plugins/kibana/public/home/components/home_app.js#L20)

Thanks for the tip, though I tried following your advice and ended up with this and it is giving me errors

export default function (kibana) {  
return new kibana.Plugin({  
id: 'my\_team\_plugin',  
uiExports: {  
docViews: ['plugins/my\_team\_plugin/team\_plugin']

```
   injectDefaultVars(server) { 
     const config = server.config(); 
     return { 
       tx: config.get('my_team_plugin.tx'), 
     }; 
   }, 
 }, 

 config(Joi) { 
   return Joi.object({ 
     enabled: Joi.boolean().default(true), 
     tx: Joi.string(), 

   }).default(); 
 }, 

```

});  
}  
if not in index.js where do I put it? That is where it is in the apm example you referenced.

Looks like your index.js file is not quit right. You do not have a comma after docViews. What version of kibana are you using? What is the error message?

```auto
export default function (kibana) { 
   return new kibana.Plugin({ 
     id: 'my_team_plugin', 

     uiExports: { 
       docViews: ['plugins/my_team_plugin/team_plugin'],
       injectDefaultVars(server) { 
         const config = server.config(); 
         return { 
           tx: config.get('my_team_plugin.tx'), 
         }; 
       }, 
     }, 

     config(Joi) { 
       return Joi.object({ 
         enabled: Joi.boolean().default(true), 
         tc: Joi.string(), 
       }).default(); 
     }, 
   }); 
}

```

looks like the cause of the error was that the joi string and the config.get variable were differe (which was a typo. now corrected). But chrome injector likely wont work with my environment. is there another way to load it as a variable in a way that will allow edits to take place without re-optimizing?

Why would chrome injector not work in your environment?
