A package with circular dependency will result in stack overflow

[brawaru]

Environment

Package: c12@​1.1.2.
Node: v16.14.2, v18.14.0.

Reproduction

1. Import a package (normally or dynamically) that has a circular dependency, inside your configuration file. Example: import-meta-resolve.
2. Try to load that file.

Describe the bug

JITI gets stuck in recursion until eventually it crashes with ‘Maximum call stack size exceeded’.

Additional context

StackBlitz: https://stackblitz.com/edit/node-fughmd?file=example.config.mjs&view=editor.

This is not reproduceable with JITI alone.

Workaround: make it impossible to analyse import by using expression rather than a literal inside dynamic import statement. For example: import('i' + 'mport-meta-resolve').

Thanks for nice reproduction @brawaru. I have narrowed it down to a specific option of jiti. It only happens when require cache is disabled and we do disable it for jitiOptions in c12 by default in order to support invalidating config reloads.

As an alternative workaround, you can use jitiOptions:

const { config } = await loadConfig({
  name: 'example',
  jitiOptions: {
    requireCache: true,
  },
});
