💻 Code

import packageJson from './package.json' with { type: 'json' }

🙁 Actual behavior

We get the following error:

TS2823: Import attributes are only supported when the --module option is set to esnext, nodenext, or preserve

🙂 Expected behavior

The docs state the following:

nodenext: Currently identical to node16, but will be a moving target reflecting the latest Node.js versions as Node.js’s module system evolves.

Either the syntax should be supported on node16 or the documentation needs to be updated.

This is working as intended, hence the documentation mentions:

will be a moving target reflecting the latest Node.js versions as Node.js’s module system evolves.

One could bike-shed and argument it should be reworded from "will be" to "is".

But the docs state "Currently identical to node16", maybe remove that part to reflect the current state? I think this is more clear:

nodenext: A moving target reflecting the latest Node.js versions as Node.js’s module system evolves.

Import attributes only work on node 18 and above, but typescript has no node18 or higher target. So I think the best course of action would be to add such a target and alias nodenext to it.

nodenext should always be an alias to the latest node target, imho. Not have special behaviour as it does now.

This was fixed a while ago and I forgot to link it: https://www.typescriptlang.org/docs/handbook/modules/reference.html#node16-node18-nodenext
