Cannot resolve built-in Node's "crypto" library

    apps/convex/utils.ts:5:19:
      5 │ import crypto from "crypto";
        ╵                    ~~~~~~~~

  The package "crypto" wasn't found on the file system but is built into node. Are you trying to
  bundle for node? You can use "platform: 'node'" to do that, which will remove this error.

Convex functions can run in two runtimes:

I would migrate to that browser like crpyto global, but there will to much code to change. So i decided to stick to node's crypto This trick worked for me:- take out all the logics that use node's crypto as utility function into a separate file. doesn't matter if you have written the crypto module's import statement or not, if you have used those utility function in some other file, you have to put "use node"; directive this works only for Actions. this wont work for Query or Mutation because only Actions can use Node.js runtime and query mutation cant
