How to use namespace in managed lightning components

If you are working on a lightning component and it’s going to be a part of a managed package then you need to take care of namespace in client side JS code if you are accessing any custom field. This can be handled in various ways but I found one very quick way to handle this. Using wrapper could be a best way but it’s time consuming so you can use the following way.

Get the namesapce from server side controller and use that in the lightning components.

NamespaceDemoComp.cmp

NamespaceDemoCompController.cls

NamespaceDemoCompController.js

NamespaceDemoCompHelper.js

So, you can see in the above example that using namespace in JS code can save lot of time as compared to wrapper classes. Expense__c is a custom object and this code will take care of the namespace automatically based on the running environment. If there is a namespace then it will be added as suffix with field’s API names in JS code.

Happy coding 🙂
