Hi,

Sorry for not responding for so long. What about using @rollup/plugin-node-resolve like in the example?

[abenz1267]

didn't wanna open up a new issue... so i'm hijacking this as it's SOMEWHAT related.

I can't build, because imports are missing the *.ts extension, which Typescript omits by default. I'd like to keep it that way. How can i make SWC resolve those imports correctly? Or do i have to add the extension to every import now?

If i add extensions: ['.ts'], to the nodeResolve plugin like in the example, it can't resolve node_modules imports. Tries to resolve "repeat.ts" instead of "repeat.js" as in the actual import.

@abenz1267, have you tried extensions: ['.js', '.ts']?

[abenz1267]

Oh yeah, i did.

Error: Could not load /home/andrej/Documents/litdo/node_modules/lit/directives/repeat.ts (imported by src/index.ts): ENOENT: no such file or directory, open '/home/andrej/Documents/litdo/node_modules/lit/directives/repeat.ts'

Is the whole error. Keep in mind the actual import calls repeat.js not repeat.ts.

Any update on this? Ideally, it should not require @rollup/plugin-node-resolve for relative files.

Related: even using @rollup/plugin-node-resolve, I couldn't get this plugin / SWC to resolve index files, like: ./src/ui/Button/index.ts when using

import { Button } from '@ui/Button'

Is this a SWC issue, and regardless, is there a way to get SWC to resolve paths using other rollup plugins? It doesn't seem like module resolution in SWC uses the Rollup flow to resolve paths.
