is it possible to remove core packages from meteor?
I want to remove Blaze and Spacebars. In this case meteor should ship my index.html as it is, with no parsing or templating on his side.
As of 2020 this is possible for nearly all packages. There are no longer hard dependencies for Blaze and you can even remove Mongo and run Meteor with an SQL database.
To test this you should check out the various options for creating a new Meteor project - They only define which packages are added initially when creating the project and you can freely add / remove even core packages.
