My project is Node/Fastify written in typescript.

Steps to Reproduce:

  1. Set the compiler compiler options in a tsconfig:
{
    "module": "ESNext",
    "target": "ESNext",
    "moduleResolution": "Bundler"
}

The suggested paths to import, for example, are:

  1. Change to "moduleResolution": "Node" and then reload VSCode.

The suggested paths to import are now:

I want the QuickFix Suggestions from 2. while using "moduleResolution": "Bundler"

I have these settings:

{
    "javascript.preferences.importModuleSpecifierEnding": "minimal",
    "javascript.preferences.importModuleSpecifier": "non-relative"

    "typescript.preferences.importModuleSpecifierEnding": "minimal",
    "typescript.preferences.importModuleSpecifier": "non-relative",
}

Research direction

Start by reproducing the import QuickFix suggestions with the shown TypeScript compiler options and importModuleSpecifier settings, comparing Bundler with Node resolution. Trace the TypeScript or VS Code entry point responsible for suggested import endings. Done means Bundler produces the requested minimal or non-relative suggestions consistently with the configured preferences.
