ESLint v10.4.0 released

Highlights

New `includeIgnoreFile()` helper

This release introduces the includeIgnoreFile() helper for configuration files that allows for including patterns from .gitignore files or any other files with gitignore-style patterns.

Previously available in the external package @eslint/compat, the new includeIgnoreFile helper function is exported from the eslint/config entrypoint and provides an extended API that allows multiple files to be included and patterns to be interpreted relative to the location of those files, which is a common use case for nested .gitignore files.

// eslint.config.js
import { defineConfig, includeIgnoreFile } from "eslint/config";
import { fileURLToPath } from "node:url";
const rootGitignorePath = fileURLToPath(
new URL(".gitignore", import.meta.url)
);
const nestedGitignorePath = fileURLToPath(
new URL("some/other/folder/.gitignore", import.meta.url),
);
export default defineConfig([
includeIgnoreFile([rootGitignorePath, nestedGitignorePath], {
// option to interpret patterns relative to the locations of the specified files
gitignoreResolution: true,
}),
{
// your overrides
},
]);
