Do I need mongo DB if I am using meteor just to call external API

hi
I am reading how to scale my app best. All my app does is talks to an external api for all its back end operations and all I use meteor is to render and display the information from the api. For this setup do I need mongo DB in my backend with oplog?

Thanks

As long as you don’t pull in packages that depend on Mongo and thus try to establish a MongoDB connection you can run Meteor without a MongoDB server.
But even if you or some of the packages you use make a little use of a MongoDB then you’re also still fine without an oplog as it won’t affect the performance significantly.

I am not sure how to figure out which packages are dependant on mongo DB. I use the below packages can you pls let me know if I need mongo DB using this list?
