NestJs Build option to create single file

I am having to NestJS app on running npm run build one app creates one single file and the other app create as many .js files as I have in in may app

I am unable to find the settings where I can say I need one single file. Any NestJS Developer who can help

Solution

This is probably from nest build being ran inside a monorepo and Nest using webpack to bundle the source code together. In a non-monorepo project, nest build uses tsc, Typescript's compiler, to transpile the ts files to js which outputs each file individually rather than bundling them together.
