Is there a way to restrict users in Salesforce to using only one instance of a Lightning Web Component?
I am new to Salesforce Lightning Web Components and looking for a solution to limit the number of instances a user can create through either permissions or code.
The desired outcome is that only one LWC instance should be visible, allowing the user to drag and drop it only once to fulfill the requirement.
It has been mentioned by David that restricting the number of component instances on a page is not ideal, but nonetheless possible. The workaround involves importing a method from another LWC's controller and maintaining a counter within it to track the invocations. By invoking this method in the first LWC, you can determine whether to render the UI based on the returned value. This allows for controlling the number of component instances displayed on the page simultaneously. However, keep in mind that the rendering of instances will occur randomly. This concept aligns with the idea behind the shared back-end controller in the pubsub recipe found here
If you're looking for ways to control the permissions of your component in the Lightning App Builder as a Salesforce administrator, you can adjust the Component Configuration File. This file allows you to specify where your component can be utilized by defining the targets element. While you can't restrict the number of components on a page, it's common practice to have multiple components displayed conditionally based on user or record attributes.
