customMetadataCmpHelper.js	JavaScript Controller Helper	It is hold for Javascript Helper Function to get Custom Metadata values from apex method.
customMetadataCtrl.apxc	Apex Controller	It is used for get the custom metadata record type values from Apex Class Method
customMetadataApp.app	Lightning Application	It is used for call the component and preview on browser.
Custom Metadata API:- customMetadataIntegrate__mdt	Fields of Custom Metadata record type:- MasterLabel, Active__c, Api_Endpoint__c, Bucket__c, Call_Back_URL__c, Folder__c

Create JavaScript Controller

Step 2:- Create Lightning Component : customMetadataCmpController.js

From Developer Console >> File >> New >> Lightning Component >> JavaScript Controller

customMetadataCmpController.js [JavaScript Controller]

```
   ({
```

	doInit : function(component, event, helper) {

        helper.initHelper(component, event, helper);

```
	},
```
```
 
```
```
 
```

    metaActionRow: function ( component, event, helper ) {

        var action = event.getParam('action');

        var row = event.getParam('row');

        //alert('row ' + JSON.stringify(row));

```
        switch (action.name) {
```
```
            case 'edit_record':
```

                component.set( "v.record", row );

                var metaEle = component.find( "metaRowPopupId" );

        		$A.util.removeClass( metaEle, "slds-hide" );

```
                break;
```
```
        }
```
```
    },
```

    handleCancelPopupClick: function( component, event, helper ){

        var metaEle = component.find( "metaRowPopupId" );

        $A.util.addClass( metaEle, "slds-hide" );

```
    },
```
```
 
```
```
 
```
```
})
```

Create JavaScript Helper

Step 3:- Create Lightning Component : customMetadataCmpHelper.js

From Developer Console >> File >> New >> Lightning Component >> JavaScript Helper

customMetadataCmpHelper.js [JavaScript Helper File]

```
   ({
```

	initHelper : function(component, event, helper) {

```
        let rowActions = [{ 
```
```
            'label': 'Edit', 
```
```
            'iconName': 'action:edit', 
```
```
            'name': 'edit_record'

```
 
```

        let columns = [

            { label: 'MasterLabel', fieldName: 'MasterLabel', type: 'text' },

            { label: 'Api Endpoint', fieldName: 'Api_Endpoint__c', type: 'url' },

            { label: 'Bucket', fieldName: 'Bucket__c', type: 'text'},

            { label: 'Call Back URL', fieldName: 'Call_Back_URL__c', type: 'url'},

            { label: 'Active', fieldName: 'Active__c', type: 'text'},

            { type: 'action', typeAttributes: { rowActions: rowActions } }

```
        ];	
```
```
 
```

        component.set( "v.columns", columns );

```
 
```

        helper.retrieveDataHelper( component );

```
 
```
```
    },
```
```
 
```

    retrieveDataHelper : function( component ) {

		var action = component.get("c.customMetaObj");

        action.setCallback( this, function( response ) {

            var state = response.getState();

```
            if( state === "SUCCESS") {
```

                var result = response.getReturnValue();

                //alert('result' + JSON.stringify(result));

                //console.log( response.getReturnValue() );

                component.set( "v.data", result );

```
            }
```

            else if (state === "INCOMPLETE") {

            	alert('Error in the response');

```
            }
```

            else if (state === "ERROR") {

                var errors = response.getError();

```
                if (errors) {
```

                    if (errors[0] && errors[0].message) {

                        console.log("Error message: " +

                                 errors[0].message);

```
                    }
```
```
                } else {
```

                    console.log("Unknown error");

```
                }
```
```
            }
```
```
        });
```
```
 
```
```
        $A.enqueueAction( action );
```
```
    },
```
```
 
```
```
 
```
```
 
```
```
})
```

Create Apex Class Controller

Step 4:- Create Apex Class : customMetadataCtrl.apxc

From Developer Console >> File >> New >> Apex Class

customMetadataCtrl.apxc [Apex Class Controller]

```
    public class customMetadataCtrl {
```
```
 
```
```
  @AuraEnabled
```

    public static List<customMetadataIntegrate__mdt> customMetaObj(){

        List<customMetadataIntegrate__mdt> metaObj = [SELECT Id, MasterLabel, Api_Endpoint__c, Bucket__c, Call_Back_URL__c, Folder__c, Active__c FROM customMetadataIntegrate__mdt];

        system.debug('metaObj#__11 ' + metaObj);

```
        RETURN metaObj;
```
```
    }
```
```
 
```
```
 
```
```
}
```

Create Lightning Application

Step 5:- Create Lightning Application : customMetadataApp.app

From Developer Console >> File >> New >> Lightning Application

customMetadataApp.app [Component Application File]

   <aura:application extends="force:slds">

```
    <c:customMetadataCmp/>
```
```
</aura:application>
```
