PR #14475: feat(next): turbopack build support, fix incorrect handling of external packages

Repository: payloadcms/payload
Author: AlessioGr
State: closed | merged: True
Link: https://github.com/payloadcms/payload/pull/14475

Description (problem / solution / changelog)

Fixes https://github.com/payloadcms/payload/issues/14338 and https://github.com/vercel/next.js/issues/85110#issuecomment-3444212808.

This PR should fix support for using turbopack to build your Next.js project (which is now the default in Next.js 16, unless you pass next build --webpack).

Previously, we were directly externalizing dependencies like libsql as they cause an error when being bundled. However, as those dependencies were not installed at the top-level by the user, the resulting require('libsql') calls could fail in production.

Turbopack threw the following warning:

Packages that should be external need to be installed in the project directory, so they can be resolved from the output files.\nTry to install it into the project directory by running

However, we ignored this warning, as we cannot force users to manually install dependencies of our dependencies.

In Next.js 16, when using Turbopack build, this is no longer a warning but an error, which is why attempting to use turbopack build right now will not work.

This PR properly fixes this externalization issue, by externalizing the entry points of those problematic packages (our db adapters). This means we no longer need to hide the warning.

Which area(s) are affected? (Select all that apply)

Turbopack

Which stage(s) are affected? (Select all that apply)

next build (local), next dev (local)

Additional context

This project is based on the PayloadCMS official "blank" starter template but updated to Next.js 16.
The build passes with next build --webpack so I'm assuming it's an issue with Turbopack.

extent analysis

TL;DR

The most likely fix is to configure Turbopack to ignore certain files or modules that are causing the build to fail.

Guidance

Review the import traces to identify the modules causing the errors, such as @esbuild/darwin-arm64/README.md and @esbuild/darwin-arm64/bin/esbuild.
Consider adding a next.config.js configuration to exclude these modules from being processed by Turbopack.
Check the Next.js documentation on Turbopack configuration to see if there are any options available to ignore certain files or modules.
Try running the build with the --webpack flag to see if the issue is specific to Turbopack.

Example

No code example is provided as the issue is related to configuration and module imports.

Notes

The issue seems to be related to Turbopack not being able to handle certain modules or files, and the build passes when using Webpack. Further investigation is needed to determine the exact cause and solution.

Recommendation

Apply a workaround by configuring Turbopack to ignore the problematic modules or files, as the issue seems to be specific to Turbopack and not a general build issue.
