Docs: clarify how to fix "Too many files (>8) have matched the default project" #9450
Description
Before You File a Documentation Request Please Confirm You Have Done The Following...
- I have looked for existing open or closed documentation requests that match my proposal.
- I have read the FAQ and my problem is not listed.
Suggested Changes
I have been unable to upgrade typescript-eslint past 7.5.0; doing so gives a "Too many files have matched the default project" whenever I try to lint.
My languageOptions are
languageOptions: {
parser: tseslint.parser,
parserOptions: {
EXPERIMENTAL_useProjectService: true,
},
},
The error I'm getting:
common:lint: <redacted path>
common:lint: 0:0 error Parsing error: Too many files (>8) have matched the default project.
common:lint:
common:lint: Having many files run with the default project is known to cause performance issues and slow down linting.

common:lint: See https://typescript-eslint.io/troubleshooting/typed-linting#allowdefaultprojectforfiles-glob-too-wide

I've read various issues and docs and none of them answer my question.
- The FAQ tells me I've configured
allowDefaultProjectForFileswith too wide a glob. This isn't true; I haven't configured the property at all and I can't find what its default is anywhere. - I found Bug: "Too many files (>8) have matched the default project" error triggers on every file after 8 #9032 but it was closed and the issue still persists when I try to use the latest 7.x.
I'm certainly open to the possibility that something is wrong with my linting configuration, but I couldn't find anything in the docs to help me investigate this. (Are node_modules files supposed to be opened by typescript-eslint?)
From my perspective, it looks like a breaking change was released and it would be nice to at least clarify in the docs how folks with a previously working v7 config can upgrade.
