Jest config with typescript

jest.config

  moduleDirectories: ["node_modules", "src"],
  // Transforms tell jest how to process our non-javascript files.
  // Here we're using babel for .js and .jsx files, and ts-jest for
  // .ts and .tsx files.  You *can* just use babel-jest for both, if
  // you already have babel set up to compile typescript files.
  transform: {
    // "^.+\\.jsx?$": "babel-jest",

  },
  // In webpack projects, we often allow importing things like css files or jpg
  // files, and let a webpack loader plugin take care of loading these resources.
  // In a unit test, though, we're running in node.js which doesn't know how
  // to import these, so this tells jest what to do for these.
