Build Errors

SaaSStinger Lite uses a production build process to verify:

• TypeScript correctness
• Next.js compatibility
• Dependency resolution
• Application configuration

Common validation commands:

pnpm tsc --noEmit

pnpm lint

pnpm build

Build Troubleshooting Process

When a build fails:

Build Error

    ↓

Read First Error

    ↓

Fix Root Cause

    ↓

Run Type Check

    ↓

Run Build Again

Fix the first meaningful error before investigating later errors.

TypeScript Errors

Symptoms

Example:

Type error: Property does not exist

or:

Argument of type X is not assignable

Solution

Run:

pnpm tsc --noEmit

Check:

• Incorrect types
• Missing imports
• Invalid function arguments
• Nullable values

Common TypeScript Issues

Missing Type Definition

Example:

Cannot find module

Solution

Verify:

• Package is installed
• Type package exists
• Import path is correct

Example:

pnpm add package-name

Module Not Found Errors

Example

Cannot find module '@/components/example'

Check

Verify:

1. File exists.
2. Filename casing matches.
3. Import alias is correct.

Example:

import Component from "@/components/example";

Path Alias Problems

SaaSStinger Lite uses:

@/

for:

src/

Example:

import { cn } from "@/lib/utils";

Check tsconfig.json

Verify:

{
  "paths": {
    "@/*": [
      "./src/*"
    ]
  }
}

Next.js Build Errors

Symptoms

Examples:

Failed to compile

or:

Build failed

Common Causes

• Server/client component mismatch
• Invalid imports
• Missing environment variables
• TypeScript failures

Server and Client Component Errors

Symptoms

Example:

You're importing a component that needs useState

Cause

A client component is being used inside a server component incorrectly.

Solution

Add:

"use client";

only where client behavior is required.

Avoid converting entire sections to client components unnecessarily.

Environment Variable Build Errors

Symptoms

Example:

Firebase configuration missing

Solution

Verify:

.env.local

contains required values.

Client variables:

NEXT_PUBLIC_FIREBASE_PROJECT_ID=

Server variables:

FIREBASE_PROJECT_ID=
FIREBASE_CLIENT_EMAIL=
FIREBASE_PRIVATE_KEY=

Firebase Admin Build Issues

Symptoms

Examples:

Firebase Admin initialization failed

Check

Verify server-only imports.

Firebase Admin should not be imported into browser components.

Correct:

Server Action

    ↓

Firebase Admin

    ↓

Firestore

Incorrect:

Client Component

    ↓

Firebase Admin

MDX Documentation Build Errors

Symptoms

Examples:

Cannot find module mdx/types

or:

MDX compilation failed

Check

Verify required MDX packages are installed.

Common packages:

@mdx-js/mdx

@mdx-js/react

Check MDX Components

Verify:

mdx-components.tsx

exports valid MDX components.

Dependency Problems

Symptoms

Examples:

• Build works on one machine but fails on another
• Missing packages
• Version conflicts

Solution

Clean installation:

rm -rf node_modules

Remove lock issues only when necessary.

Then:

pnpm install

Lock File Issues

SaaSStinger Lite uses:

pnpm-lock.yaml

Do not manually edit lock files.

Regenerate through:

pnpm install

Lint Errors

Symptoms

Example:

ESLint error

Solution

Run:

pnpm lint

Fix:

• Unused variables
• Incorrect hooks
• Unsafe patterns
• Formatting issues

Production Build Checklist

Before deployment:

Run:

pnpm tsc --noEmit

Then:

pnpm lint

Then:

pnpm build

All should complete successfully.

Debugging Build Failures

Collect:

• Complete error message
• First failing file
