VSCode extension editor's "Test Flow" conflicted with existing tsconfig

[its-frank-huang]

Problem

When I click the "Test Flow" button, an error will appear

Unexpected error while handling message from webview: 
Could not find Custom Add in {absolute path to project}/add.flyde.ts. 
The following errors were thrown, and might be the reason the node is not properly resolved. 
Errors: Error loading module "{absolute path to project}/add.flyde.ts": Unexpected token 'export'

Possible Cause

After some fiddling around, I found out that changing the module to NodeNext and moduleResolution to NodeNext seems to make it work

Steps to Reproduce

1. Init a regular npm project
2. Install @flyde/core using package manager
3. Create a Flyde flow
4. Add a custom code node (the add in the tutorial will do)
5. Import the custom code node
6. Click "Test Flow" (it should work)
7. Create a tsconfig.json
8. Change module to ESNext and moduleResolution to ESNext
9. Click "Test Flow" (expected to fail)

Request

monorepo doesn't work either

Hey @its-frank-huang, thanks for the report and the suggested cause.
Does using "NodeNext" unblock you for now?
