I would like to have eslint enforce the rules in files outside of the src folder, eslint is currently complaining about there scripts:

Parsing error: ESLint was configured to run on `<tsconfigRootDir>/scripts/development-loader.js` using `parserOptions.project`: /development/test-backend/tsconfig.json
However, that TSConfig does not include this file.

  ],
  "rules": {
    "no-console": "error"
  },

  }
}

Adding directories to the tsconfig.json include array will resolve that issue, however, on build those files are also compiled to the dist directory (what i don't want)

well, since they that isn't a ts file, you maybe don't want to use the eslint file that's all set up for ts linting?

btw, you have plugin:@typescript-eslint/eslint-recommended twice in your extends array, neither of which you need since it's included in @typescript-eslint configs

Good catch, removed both of them!

It also shows those messages on .ts files

#

so to clarify; you have a ts project with a ts src, but with other js/ts files outside of src that aren't part of the build?

eager egret Sep 30, 2023, 10:08 AM

#

That's correct, they are used for database migrations and other dev scripts

#

i think in that case, you would have 2 tsconfigs, one for the build and one for the entire project, and you can use 1 eslintrc over the entire project with the latter config
that might not work with the js files though. i guess you could fix that by providing overrides in the eslintrc

overrides did the trick with an additional tsconfig file, thanks!
