I quite like this format

const projectName = (params: TemplateStringsArray) =>
  `hello-world-${stage}-${String.raw(params)}`;

And use like so in my resources

const resourceGroup = new azure.resources.ResourceGroup(projectName`rg`, {
  resourceGroupName: `Hello-World-${stage}`,
  location: azure.migrate.AzureLocation.UkSouth,
});

Will generate a URN like

hello-world-dev-rg
