Results not reported from Messages.ts file

[vsobotka]

We have a src/Messages.ts file, containing all localisation messages used in the app in a format like this:

import { defineMessage } from "react-intl";

export const messageLogIn = defineMessage({
  id: "Account.logIn",
  defaultMessage: "Log In",
});

export const messageLogOut = defineMessage({
  id: "Account.logOut",
  defaultMessage: "Log Out",
});

We have a tsconfig

{
  "compilerOptions": {
    "target": "es5",
    "lib": ["dom", "dom.iterable", "esnext"],
    "jsx": "react-jsx",
    "jsxImportSource": "@emotion/react",
    "module": "esnext",
    "moduleResolution": "node",
    "resolveJsonModule": true,
    "allowJs": true,
    "removeComments": true,
    "noEmit": true,
    "isolatedModules": true,
    "allowSyntheticDefaultImports": true,
    "esModuleInterop": true,
    "forceConsistentCasingInFileNames": true,
    "strict": true,
    "noImplicitAny": true,
    "noImplicitThis": true,
    "useUnknownInCatchVariables": true,
    "alwaysStrict": true,
    "noImplicitReturns": true,
    "noFallthroughCasesInSwitch": true,
    "allowUnusedLabels": true,
    "allowUnreachableCode": false,
    "skipDefaultLibCheck": true,
    "skipLibCheck": true
  },
  "include": ["src"]
}

And we run it like npx ts-unused-exports ./tsconfig.json in the root dir. The result does not contain that file, while the IDE can detect more than 150 unused messages.

• When I move the Messages.ts somewhere else, and create a new Messages.ts in it's place, it will report unused exports just fine
• When I use the same message definition in a different file, it will also get detected

The Messages.ts has over 10k lines. Maybe that is an issue? Why am I not seeing any results from this file?

hi @vsobotka - thanks for reporting this.

question: how is 'messages.ts' being imported?

For example, does the import statement include the .ts extension? In which case, this could be #281

The file is a bit big - although that should not really be an issue...

@mrseanryan Thanks for the reply. I just tried several things to give your more details with examples, and I realized, thanks to your question, we might have had one import * in the project for convenience. After removing that, it works as expected. Obviously. Silly me. Thanks!

ts-prune seems to be working with this import though, so it might be a possible feature
