React hooks useState and useEffect throws errors

[cdoremus]

Using React hooks useState and useEffect in deno-react-minimal-frontend causes these errors when running the build script:

TS2339 [ERROR]: Property 'useState' does not exist on type '{}'.
  const [errorMessage, setErrorMessage] = React.useState('')
                                                ~~~~~~~~

TS2339 [ERROR]: Property 'useEffect' does not exist on type '{}'.
  React.useEffect(() => {
        ~~~~~~~~~
    at file:///Users/craigdoremus/git/cdoremus/deno-react-minimal-frontend/src/components/App.tsx:20:9

VSCode with the Deno extension installed displays no errors.

When npm start is run, the browser renders a blank page with the following errors in the JavaScript console:

client.bundle.js:18749 The above error occurred in the <App> component:
    in App

Consider adding an error boundary to your tree to customize error handling behavior.

UPDATE:

• Fixing in branch: https://github.com/quaos/deno-react-minimal-frontend/tree/1-fix-react-hooks-bundle-error
• When modified tsconfig.json and bundle command to include: --config tsconfig.json:
  Can bundle successfully, but running in browser yields error:
  Uncaught TypeError: Cannot read property 'default' of undefined at react_16_9_0_1_1["default"]
