How to solve the problem about the size of mobile terminal project?

A mobile terminal project of
company is quite special. The module was written by the programmer of Party A and ran on the framework of our company. 37M remained after compression and packaging, which mainly contained a bundle folder and other static resources, and the bundle file was each module code written by the programmer of another party, accounting for 30M. The problem now is that the company requires that the maximum size of the project should not exceed 50M, so the bundle folder cannot be stored in our frame here.

# I thought is only the bundle folder on the server or other offline mode, you have any Suggestions or other good method
