How to add an word for a line where transpose has done

Question

I have a file fruits:

apple grapes banana orange

By using

cat < fruits | tr "\n" ","

It will give output as

apple,grapes,banana,orange,

Here I want to print the file name also along with the output like

fruits|apple,grapes,banana,orange

How can I do it?

If it is a variable like

$HEALTHYFRUITS

where we read all the fruits one by one and the file name is fruits

and

echo $HEALTHYFRUITS | tr "\n" ","

here I want to print

fruits|apple,grapes,banana,orange
