What did you do?
Configuration
import { includeIgnoreFile } from '@eslint/compat'; import js from '@eslint/js'; import svelte from 'eslint-plugin-svelte'; import { defineConfig } from 'eslint/config'; import globals from 'globals'; import { fileURLToPath } from 'node:url'; import ts from 'typescript-eslint'; import svelteConfig from './svelte.config.js'; const gitignorePath = fileURLToPath(new URL('./.gitignore', import.meta.url)); export default defineConfig( includeIgnoreFile(gitignorePath), js.configs.recommended, ...ts.configs.recommended, ...svelte.configs.recommended, { languageOptions: { globals: { ...globals.browser, ...globals.node }, }, rules: { // typescript-eslint strongly recommend that you do not use the no-undef lint rule on TypeScript projects. // see: https://typescript-eslint.io/troubleshooting/faqs/eslint/#i-get-errors-from-the-no-undef-rule-about-global-variables-not-being-defined-even-though-there-are-no-typescript-errors 'no-undef': 'off', }, }, { files: ['**/*.svelte', '**/*.svelte.ts', '**/*.svelte.js'], languageOptions: { parserOptions: { projectService: true, extraFileExtensions: ['.svelte'], parser: ts.parser, svelteConfig, }, }, }, ); Initialize a SvelteKit project using the Svelte CLI (v0.9.9)
What did you expect to happen?
It used to work flawlessly, but is broken after recent package installation(update).
Downgrading @eslint/compat to @1.4.0 fixed the type error in existing repositories.
"@eslint/compat": "^1.4.1", "@eslint/js": "^9.38.0", "eslint": "^9.38.0", "eslint-plugin-svelte": "^3.12.5", "typescript-eslint": "^8.46.2",What actually happened?
The default SvelteKit config shows TypeScript error in the following line:
