Alias plugin not working with swc plugin. about rollup-plugin-swc

[jpanduro-blackbird]

I think the following config is already doing the minification by lines

jsc: {
    minify: { sourceMap: true }
  },
  minify: true,

Our intent is to not include ua-parser-js library in the bundle in certain cases because of its size. For those purposes we were using @rollup/plugin-alias, which replace it with mocked module, that returned null. And this plugin stopped working after starting using rollup-plugin-swc3

Is there any idea how I can solve this problem?

rollup-plugin-swc3 acts more as an alternative to @rollup/plugin-typescript rather than rollup-plugin-terser. If you intend to replace terser, you could import swcMinify from rollup-plugin-swc3 instead.

Could you provide a minimum reproduction so I can pinpoint the issue?

rollup-plugin-swc3 has implemented a customized module resolving to work with TypeScript files while @swc/core can expand aliased imports during the transformation. Although I suspect that this might be the cause of the issue, I can't rectify it without a minimal reproduction.

In the meantime, swcMinify doesn't include a customized module resolving and swc transformation. Therefore simply importing swcMinify from rollup-plugin-swc3 might be the quickest workaround for this issue.

Thanks for suggestions! Basically, I was able to achieve it by using rollup-plugin-ignore instead
