Removed any @forge/ui reference, still getting Cannot find name 'ForgeUI' Error

Forge
1

I’m trying to migrate an app from Forge UI 1 to the new UI kit.

I’ve removed any reference to the @forge/ui components and the package.
However, when I run the forge deploy command, I get tons and tons of this error:

      TS2304: Cannot find name 'ForgeUI'.[tsl] ERROR in /home/roman/dev/no-more-secrets/src/components/secretsCustomField/secretElements.tsx(34,22)
      TS2304: Cannot find name 'ForgeUI'.[tsl] ERROR in /home/roman/dev/no-more-secrets/src/components/secretsCustomField/secretElements.tsx(39,14)
      TS2304: Cannot find name 'ForgeUI'.[tsl] ERROR in /home/roman/dev/no-more-secrets/src/components/secretsCustomField/excludedAttachmentMessage.tsx(15,10)
      TS2304: Cannot find name 'ForgeUI'.[tsl] ERROR in /home/roman/dev/no-more-secrets/src/components/secretsCustomField/excludedAttachmentMessage.tsx(17,18)

However, there is no reference to ForgeUI in that file.

I’ve no idea what is adding that reference? Seems some configuration doing that?

@RomanStoffel
You get those errors when you import some UI elements from @forge/react into your file which is supposed to live in the backend side of things (resolver).
When you import a file, the file and all its imports are also imported recursively.

You cannot have dependencies to the UI in files for the resolver.
You also cannot have dependencies to the @forge/ui in files for the frontend.

It’s important to break those dependencies by separating clearly those elements in different files.

Hope that helps !

I ran into a similar issue without any extra imports from @forge/react or elsewhere - just a pure @forge/ui macro configuration. Unfortunately, the only workaround that helped me was:

import ForgeUI, {
  MacroConfig,
  Option,
  Select,
  TextArea,
  render,
  useState,
} from '@forge/ui';

if (false) ForgeUI; // wtf fix for "Cannot find name 'ForgeUI'" issue

Typo.

You also cannot have dependencies to the @forge/ui in files for the frontend.
Should be
You also cannot have dependencies to the @forge/api in files for the frontend.
