ESLint + Prettier Setup for Next.js 15

eslint-prettier-next-15 (v0.1.11) is an automated CLI tool that configures ESLint (v9) and Prettier (v3) for Next.js 15 projects. It detects the package manager (npm, yarn, pnpm, or bun), removes old configurations, installs recommended dependencies (including @typescript-eslint, eslint-config-next, prettier plugins for import sorting and JSON formatting), and generates flat ESLint config and .prettierrc files. Designed for fresh or existing Next.js 15 apps, it enforces consistent code quality rules with zero manual setup. Updated irregularly; relies on flat config (eslint.config.mjs) and ESM-only imports.
