  ESLint: 7.22.0

  You are linting ".", but all of the files matching the glob pattern "." are ignored.

  If you don't want to lint these files, remove the pattern "." from the list of arguments passed to ESLint.

  If you do want to lint these files, try the following solutions:

  * Check your .eslintignore file, or the eslintIgnore property in package.json, to ensure that the files are not configured to be ignored.
  * Explicitly list the files from this glob that you'd like to lint on the command-line, rather than providing a glob as an argument.

Hey there, the error is this one:

You are linting ".", but all of the files matching the glob pattern "." are ignored.

Please verify that your ignore rules are correct.

@ocean90 I assumed that config should clarify that --config .eslintrc.js .eslintrc.js:

So you only want to lint *.ts files? In that case you have to set eslint_extensions: ts in your workflow.

[kosiakMD]

@ocean90 oh, got it, thanks! Does this action support a config file at all?

[ocean90]

It does, but for the list of extensions you have to use the --ext CLI argument which by default only includes .js, see https://eslint.org/docs/user-guide/command-line-interface#options.

[kosiakMD]

@ocean90 I added eslint_extensions : ts and tried with and without --conig .eslintrc.js but Prettier and seems ESLint too doesn't see my config files and make checks of ignored files and with other rules that I wrote
