How to properly configure eslint-plugin-import in a Next.js 15 (App Router) project using Flat Config and path aliases?

[Rich-Warrior]

Summary

I'm trying to get eslint-plugin-import to work properly in a Next.js 15 project that uses the new App Router and Flat Config (eslint.config.mjs).

I’m also using TypeScript with a tsconfig.json that defines path aliases like @/* -> ./src/*.

Despite configuring import/resolver for both node and typescript, ESLint still reports unresolved imports and doesn't respect the alias.I'm trying to get eslint-plugin-import to work properly in a Next.js 15 project that uses the new App Router and Flat Config (eslint.config.mjs).
