**The most common build failures in the AI Website Cloner Template stem from Node.js version mismatches, missing peer dependencies, and Tailwind CSS v4 configuration issues, all of which can be resolved by verifying [`package.json`](https://github.com/JCodesMore/ai-website-cloner-template/blob/main/package.json) requirements and reinstalling dependencies with Node 24+.**

The AI Website Cloner Template is a minimal Next.js 16 starter that combines React 19, TypeScript strict mode, Tailwind CSS v4, and shadcn/ui primitives. When cloning and building the `JCodesMore/ai-website-cloner-template` repository locally, developers frequently encounter specific toolchain compatibility issues that prevent compilation. Understanding these failure points within the actual source architecture allows for rapid debugging without compromising the template's lightweight design.

## Node.js Version Mismatches

The `engines.node` field in [`package.json`](https://github.com/JCodesMore/ai-website-cloner-template/blob/main/package.json) requires **Node.js 24 or higher**. Running older versions produces immediate binary refusal with errors like:

```

Error: Required Node version >=24.0.0. Current version: 20.x.x

```

Upgrade Node and reinstall dependencies:

```bash
nvm install 24
nvm use 24
rm -rf node_modules package-lock.json
npm ci

```

## Missing or Incompatible Peer Dependencies

`@base-ui/react` is a peer dependency of shadcn/ui components. Version mismatches trigger module resolution failures:

```

Module not found: Can't resolve '@base-ui/react/button'

```

Install compatible versions explicitly:

```bash
npm install @base-ui/react@^1.3.0 shadcn@^4.1.0

```

## Tailwind CSS v4 Configuration Errors

Tailwind v4 requires a specific PostCSS setup. A missing or outdated `postcss.config.mjs` generates:

```

Error: Cannot find module 'tailwindcss'

```

Ensure your `postcss.config.mjs` contains the proper plugin array as implemented in the repository:

```javascript
// postcss.config.mjs
export default {
  plugins: {
    tailwindcss: {},
    autoprefixer: {},
  },
};

```

Then reinstall the dev dependency:

```bash
npm install -D tailwindcss@^4

```

## TypeScript Strict Mode Violations

The repository compiles with `tsc --noEmit` using strict settings. Common errors include `TS2322: Type 'string' is not assignable to type 'ReactNode'`, usually originating from untyped props in shadcn components.

Fix type definitions in [`src/components/ui/button.tsx`](https://github.com/JCodesMore/ai-website-cloner-template/blob/main/src/components/ui/button.tsx) using explicit interfaces:

```typescript
// src/components/ui/button.tsx
import type { ButtonHTMLAttributes } from "react";
import { cn } from "@/lib/utils";

type ButtonProps = ButtonHTMLAttributes<HTMLButtonElement> & {
  variant?: "default" | "destructive";
  size?: "default" | "sm" | "lg";
};

function Button({ 
  className, 
  variant = "default", 
  size = "default", 
  ...props 
}: ButtonProps) {
  return (
    <button
      className={cn("base-classes", variant, size, className)}
      {...props}
    />
  );
}

```

Always use the `cn` utility from [`src/lib/utils.ts`](https://github.com/JCodesMore/ai-website-cloner-template/blob/main/src/lib/utils.ts) instead of manual string concatenation to ensure type-safe Tailwind class merging.

## ESLint and Next.js Linting Conflicts

Outdated `eslint-config-next` packages cause config loading failures:

```

eslint: Failed to load config "next" to extend from.

```

Update the ESLint configuration to align with Next.js 16:

```bash
npm install eslint-config-next@16.2.1
npm run lint

```

## Missing Runtime Assets

[`src/app/layout.tsx`](https://github.com/JCodesMore/ai-website-cloner-template/blob/main/src/app/layout.tsx) imports the **Geist** font via `next/font/google`. If the network is blocked or the build runs in an offline environment, the font import aborts the compile step.

Run the build with internet access once to cache the font, or replace the import with a locally-served fallback.

## Docker-Specific Build Failures

When using `docker compose up dev --build`, containers often lack the required Node version or proper `node_modules` caching.

Update your `Dockerfile` to use the correct base image:

```dockerfile
FROM node:24-alpine

```

Mount a persistent volume for `node_modules` to preserve cached dependencies between builds.

## Summary

- **Node.js 24+ is mandatory**: The `engines.node` field in [`package.json`](https://github.com/JCodesMore/ai-website-cloner-template/blob/main/package.json) enforces this strictly, and Next.js 16 requires it for the build pipeline.
- **Peer dependencies require manual verification**: Ensure `@base-ui/react` versions align with shadcn/ui expectations to avoid module resolution errors.
- **Tailwind v4 needs explicit PostCSS configuration**: Verify `postcss.config.mjs` includes the tailwindcss plugin before running builds.
- **Strict TypeScript prevents runtime errors**: Use the `cn` utility from [`src/lib/utils.ts`](https://github.com/JCodesMore/ai-website-cloner-template/blob/main/src/lib/utils.ts) for class merging and provide explicit prop types in components like [`src/components/ui/button.tsx`](https://github.com/JCodesMore/ai-website-cloner-template/blob/main/src/components/ui/button.tsx).
- **Runtime assets need network access**: The Geist font import in [`src/app/layout.tsx`](https://github.com/JCodesMore/ai-website-cloner-template/blob/main/src/app/layout.tsx) requires connectivity during initial builds to cache font files.

## Frequently Asked Questions

### Why does the build fail with "Required Node version >=24.0.0"?

The [`package.json`](https://github.com/JCodesMore/ai-website-cloner-template/blob/main/package.json) specifies Node 24 as the minimum engine requirement, and Next.js 16 relies on Node 24 features for the build pipeline. Upgrade using `nvm use 24` or install the latest LTS, then run `rm -rf node_modules && npm ci` to reinstall dependencies with the correct engine.

### How do I resolve "Cannot find module '@base-ui/react'" errors?

This indicates a peer dependency mismatch between shadcn/ui and `@base-ui/react`. Install compatible versions explicitly by running `npm install @base-ui/react@^1.3.0`, then verify the versions align with the requirements listed in [`package.json`](https://github.com/JCodesMore/ai-website-cloner-template/blob/main/package.json) before reinstalling all dependencies.

### What causes TypeScript TS2322 errors in shadcn components?

The repository enforces strict mode via [`tsconfig.json`](https://github.com/JCodesMore/ai-website-cloner-template/blob/main/tsconfig.json). These errors occur when component props lack explicit types or when using `any`. Import `ButtonHTMLAttributes` from React and use the `cn` utility from [`src/lib/utils.ts`](https://github.com/JCodesMore/ai-website-cloner-template/blob/main/src/lib/utils.ts) to ensure type-safe class merging in components like [`src/components/ui/button.tsx`](https://github.com/JCodesMore/ai-website-cloner-template/blob/main/src/components/ui/button.tsx).

### Why does the Docker build fail while local builds succeed?

Docker containers often use older Node images or lack persistent `node_modules` volumes. Update your `Dockerfile` to use `FROM node:24-alpine` and ensure `node_modules` is cached between builds. The container must also have internet access to download the Geist font referenced in [`src/app/layout.tsx`](https://github.com/JCodesMore/ai-website-cloner-template/blob/main/src/app/layout.tsx).
