Next.js Turbopack Stuck on Compiling How to Fix

Next.js Turbopack Stuck on Compiling How to Fix Turbopack stuck on "Compiling..." is one of the most frustrating issues in Next.js 15 development. Your dev server starts, shows "Compiling /page", and then... nothing. It hangs indefinitely, blocking your entire development workflow. This guide provides 5 proven solutions that work in production. This article is part of our comprehensive Deploying Next.js + Supabase to Production guide. Why Turbopack Gets Stuck Turbopack can hang for several reasons: Corrupted Cache - .next cache conflicts with Turbopack Circular Dependencies - Import cycles cause infinite loops Large Files - Huge files or node_modules slow compilation Memory Issues - Insufficient RAM for compilation Incompatible Dependencies - Packages not compatible with Turbopack Quick Diagnostic Steps ## Check if it's actually stuck or just slow ## Wait 2-3 minutes first - large projects take time ## Check Node.js version (requires 18.17+) node --version ## Check memory usage ## Windows: Task Manager > Performance ## Mac: Activity Monitor ## Linux: htop or top ## Check for error messages ## Look in terminal for warnings/errors Solution 1: Clear All Caches (Works 80% of Time) The most common fix is clearing caches: ## Stop the dev server (Ctrl+C) ## Delete all cache directories rm -rf .next rm -rf node_modules/.cache rm -rf .turbo ## Clear npm cache npm cache clean --force ## Reinstall dependencies rm -rf node_modules rm package-lock.json npm install ## Start dev server npm run dev For Windows Users ## Stop dev server (Ctrl+C) ## Delete cache directories Remove-Item -Recurse -Force . next Remove-Item -Recurse -Force node_modules\.cache Remove-Item -Recurse -Force . turbo ## Clear npm cache npm cache clean --force ## Reinstall Remove-Item -Recurse -Force node_modules Remove-Item package-lock.json npm install ## Start server npm run dev Solution 2: Disable Turbopack Temporarily If clearing cache doesn't work, disable Turbopack: // next.config.mjs /** @type {import('next').NextConfig} */ const nextConfig = { // Remove or comment out turbopack option // experimental: { // turbo: {}, // }, } export default nextConfig Start Without Turbopack Flag ## Instead of: npm run dev --turbo ## Use: npm run dev ## Or update package.json: { "scripts" : { "dev" : "next dev" , // Remove --turbo flag "dev:turbo" : "next dev --turbo" , // Keep as separate command "build" : "next build" , "start" : "next start" } } Solution 3: Fix Circular Dependencies Circular imports cause Turbopack to hang: Detect Circular Dependencies ## Install circular dependency checker npm install --save-dev madge ## Check for circular dependencies npx madge --circular --extensions ts,tsx,js,jsx src/ ## Output shows circular imports: ## Circular dependency found: ## src/components/A.tsx > src/components/B.tsx > src/components/A.tsx Fix Circular Imports // BAD: Circular dependency // components/UserProfile.tsx import { UserSettings } from ' ./UserSettings ' export function UserProfile () { return < UserSettings /> } // components/UserSettings.tsx import { UserProfile } from ' ./UserProfile ' // ❌ Circular! export function UserSettings () { return < UserProfile /> } // GOOD: Break the cycle // components/UserProfile.tsx import { UserSettings } from ' ./UserSettings ' export function UserProfile () { return < UserSettings /> } // components/UserSettings.tsx // Remove import of UserProfile // Use composition or context instead export function UserSettings () { return < div > Settings < /div > } Solution 4: Optimize Large Files and Dependencies Check File Sizes ## Find large files in your project find . -type f -size +1M -not -path "./node_modules/*" -not -path "./.next/*" ## Check node_modules size du -sh node_modules ## Analyze bundle size npm install --save-dev @next/bundle-analyzer ## Add to next.config.mjs: import bundleAnalyzer from '@next/bundle-analyzer' const withBundleAnalyzer = bundleAnalyzer ({ enabled: process.env.ANALYZE === '
