Specify a different tsconfig.json for linting

[dfee]

I use a tsconfig.eslint.json for linting – this is picked up in my .eslintrc.js. However, VSCode complains because it's using tsconfig.json to validate my *.test.ts files, which is specifically excluded in tsconfig.json but included in tsconfig.eslint.json.

@dfee what does that error look like. Is it a ESLint error or a TS error (the source is denoted in [] in the error)

[dfee]

@dbaeumer Well, I'm not getting any errors in my *.test.ts files because i have:

   "exclude": ["**/__tests__", "dist", "e2e", "node_modules"],

in my tsconfig.json.

If I were able to specify (and i'm using a monorepo – which consistently uses tsonfig.eslint.json), then i'd see the appropriate ts errors.

This is then a TS problem and has nothing to do with ESLint. To my knowledge users can't control the tsconfig.json file used by the TS language server. @mjbvz is that correct?

Yes we always use files called tsconfig.json. Support for explicit tsconfig names is tracked by microsoft/TypeScript#33094
