Turbopack support: plugin breaks production builds on Next.js 16+

[rafaelbarross]

Problem

@ducanh2912/next-pwa uses workbox-webpack-plugin internally, which injects webpack configuration. Starting with Next.js 16, Turbopack is the default bundler for both dev and production builds (next build).

This causes the following error on next build:

⨯ ERROR: This build is using Turbopack, with a `webpack` config and no `turbopack` config.

This may be a mistake.

The build then fails with:

Error: Call retries were exceeded
    at ignore-listed frames {
  type: 'WorkerError'
}

Workaround

Force webpack for production builds:

// package.json
"build": "next build --webpack"

This works but loses the Turbopack build speed improvements (~30–60% faster builds).

Expected

The plugin should support Turbopack builds, or at minimum document the --webpack workaround for Next.js 16+ users.

Environment

• @ducanh2912/next-pwa: 10.2.9
• next: 16.0.7
• Node.js: (Windows 11)
