How to get stack to save dependencies?

I'm using the stack install command to save dependencies for a new project. How do I get it to save those dependencies into stack.yaml? Unless I'm missing something, I can't see where stack is recording the project dependencies and I can't seem to find anything in a docs about this.

You still keep your dependencies in a .cabal file. From the Stack FAQ:

  • A .cabal file is provided for each package, and defines all package-level metadata just like it does in the cabal-install world: modules, executables, test suites, etc. No change at all on this front.
  • A stack.yaml file references 1 or more packages, and provides information on where dependencies come from.

If you need additional versions of dependencies than the LTS Haskell snapshot you're using, you'll add them to the extra-deps portion of the stack.yaml file.
