Update

This is now expected to land with ts4.6 and it is also fixed and verifyed already.

Looks like you wanted a feature request issue. Could you please update the template and provide all of the requested details?

[frank-dspeed]

not an rollup issue needs to get fixed in typescript

[typhonrt]

@frank-dspeed et al. I think this should be reopened. On lines 48-50 of normalize.ts. If one specifies module as nodenext or node12 it is coerced to esnext in the default condition.

Given the peer dependency for @rollup/plugin-typescript being so low the only thing I can think of is adding in case statements with the actual value for nodenext and node12 for the module compiler option.
nodenext is 199
node12 is 100

[frank-dspeed]

@shellscape no it was not a request read the following if your interrested.
@typhonrt no your getting it wrong this was about our own builds of rollup/rollup it is about json imports and i was testing the rollup/rollup build with a new Experimental TypeScript version that will not get released as is in the mean while it got fixed on the TypeScript side:

but this will maybe first time happen with typescript 4.6 and 4.5 will not have the new node12 and nodenext module modes

• Discussion about the new modes Concerns with TypeScript 4.5's Node 12+ ESM Support microsoft/TypeScript#46452
• The Current json Import thing your seeing here Typescript 4.5 resolveJsonModule should also work with node12 and nodenext module and resolveTypes microsoft/TypeScript#46362

Hi @frank-dspeed I just misread your post. Indeed I should file another issue, but indeed what I mentioned pertains to node12 / nodenext support w/ @rollup/plugin-typescript.

[frank-dspeed]

@typhonrt your correct but you should not fill that issue unless your affilated with typescript in anyway if you want to take that job you can do it else i do it. I am working on typescript-rollup a typescript version with a rollup compatible ast that also can get queryed via a api.

You can See it a bit as Distributed Rollup and Typescript thats why i am following the typescript and rollup development.
