In this video tutorial, we are going to learn about how to create a new wishlist, add items to it and then get the list of all the wishlists present in our collection named product. We are going to use all the three- get, put, and post parameters in this video.
Step 1: We do a Post request to create a new wishlist.
app.post('/wishlist',function(request, response){ error message });
If the new wishlist is found it will display "wishlist" else "could not find wishlist".
Step 2: We do a get request to find the list of
Wishlists present in our collection I.e. product.
app.get('/wishlist',function(request,response) { });

Step 3: we do a put request to add new data to the newly created wishlist and check the data in Postman.
app.put('/wishlist/product/add', function(request, response){ });
Check it in POSTMAN.

Step 4: Populate the data
In the get request, modify the statement into
app.get('/wishlist',function(request,response)
{ wishlist.find({}).populate({path:'product', model:'product'}) exec(function(err,wishlist{ error message}));
populate() function in mongoose is used for populating the data inside the reference.
