METHOD 1:

There are three steps to display the barcode on your standard record detail page:

Add a custom field into the object which you want to display the
Create a visual force page to generate the
Add the visual force page into the page layout.

Step1: Create a custom picklist field

Example: Barcode Type with the values listed below.

code128
code39
ean13
ean8
qrcode
pdf417

Step 2: Create a Visualforce Page.

Note: Please re-type the single and double quotes in the Visualforce page code.

Example: For custom controller or extension:

				
					<apex: sidebar="false" showHeader="false">
<apex:includeLightning />

<script>

var barvalue = '{!JSENCODE($currentPage.Parameters.Code)}'; var barType = '{!JSENCODE($currentPage.Parameters.Type)}';

if(barvalue == undefined || barvalue == '' || barvalue == null) barvalue = "AQXOLT";
if(barType == undefined || barType == '' || barType == null) barType = "code128";

if(barType == "code128" || barType == "code39" || barType == "ean8" || barType == "ean13"){

!$Lightning.use("BarcodeZone:TestBarcodeLightning", function() { console.log('after app upload');
!$Lightning.createComponent( "BarcodeZone:ACBarcodeZoneLightning",
{Value: barvalue, BrcdType: barType}, "Con",

function(cmp) { console.log("Component created!");
});
});
}
else if(barType == "qrcode" || barType == "pdf417"){

!$Lightning.use("BarcodeZone:Test2DBarcodeLightning", function() { console.log('after app upload');
!$Lightning.createComponent( "BarcodeZone:AC2DBarcodeZoneLightning",
{Value: barvalue, BrcdType: barType}, "Con",
function(cmp) { console.log("Component created!");
});
});
}

</script>
<div id="Con"></div>
</apex:page>

For e.g., our case, we create a new Visualforce Page and add the below code for standard controller:

				
					<apex:page standardController="Product2" sidebar="false" showHeader="false">
<apex:includeLightning />


<script>

var barvalue = '{!JSENCODE($currentPage.Parameters.Code)}'; var barType = '{!JSENCODE($currentPage.Parameters.Type)}';


if(barvalue == undefined || barvalue == '' || barvalue == null) barvalue = "{!JSENCODE(Product2.ProductCode)}";
if(barType == undefined || barType == '' || barType == null)
barType = "{!JSENCODE(Product2.BarcodeZone Barcode_Type c)}";

if(barType == "code128" || barType == "code39" || barType == "ean8" || barType == "ean13"){

!$Lightning.use("BarcodeZone:TestBarcodeLightning", function() { console.log('after app upload');
!$Lightning.createComponent( "BarcodeZone:ACBarcodeZoneLightning",
{Value: barvalue, BrcdType: barType}, "Con",
function(cmp) {
console.log("Component created!");
});
});
}
else if(barType == "qrcode" || barType == "pdf417"){

!$Lightning.use("BarcodeZone:Test2DBarcodeLightning", function() { console.log('after app upload');
!$Lightning.createComponent( "BarcodeZone:AC2DBarcodeZoneLightning",
{Value: barvalue, BrcdType: barType}, "Con",
function(cmp) {
console.log("Component created!");
});
});
}

</script>
<div id="Con"></div>
</apex:page>
