`no-duplicates` false positive and autofix creates a syntax error

[NickHeiner]

From:

import type { AccountQuery } from '@netflix-internal/dnajs';
import type dnajs from '@netflix-internal/dnajs';

To:

import dnajs, type { AccountQuery } from '@netflix-internal/dnajs';

The proper autocorrect is:

import type {default as dnajs, AccountQuery} from '@netflix-internal/dnajs';

On version 2.20.0 (edit: and 2.23.4)

Another bug:

From:

import type Registration from './Registration';
import type { RouteResolver } from './Registration';

To:

import type Registration, { RouteResolver } from './Registration';

This gives TS error:

A type-only import can specify a default import or named bindings, but not both.ts(1363)

@NickHeiner that's an old version, can you try on the latest?

[NickHeiner]

Ha! Blazing fast response. I literally was doing that. 😄

[ljharb]

Thanks, that's definitely a bug.

Although I assume your OP example code is partially edited - can you provide the exact code that's failing, no "foo" or "bar"?

[NickHeiner]

🤦 lol, if I was going to edit the input, I should have edited the output as well.

I've updated the OP to be unedited. Sorry for the churn.

looks like in TypeScript, import type has to keep default and named separate. I'm not sure if Flow has the same limitation.

[NickHeiner]

Yes, I think an import type and import statement need to be separate.

[ljharb]

@NickHeiner yes but in this case it's two import type statements that can't be combined, despite the equivalent import statements being combineable.

[NickHeiner]

Right. Also, I found what the right edit should be, and updated the OP to reflect it.

[ljharb]

While { default as works, I do not think that's the proper autocorrect - i would never want to have default as in my codebase. I think those should just be left as two separate statements.
