Is it possible to import declaration files with this plugin?

I have a dependency with a single .ts source file that imports declarations from many .d.ts declaration files. When Rollup hits a declaration file, I get a PARSE_ERROR telling me that Rollup is trying to parse the TypeScript declaration file as an ES module. I tracked that down to the exclude setting for this plugin which skips .d.ts files by default. After setting exclude: [], this plugin parses the file, but whatever ES module it returns to Rollup is missing the declarations inside, because I get a MISSING_EXPORT error. Is there a way to see what ES module this plugin is returning for a given TS declaration file? Is there a way to get it to include all the exports in a declaration file?

For rollup, the problem is that d.ts don’t contain any code that translate to java script – translated d.ts file is an empty js file.

Normally you are not supposed to import d.ts files directly, but let typescript find them itself (by setting types parameter in package, etc).

Going to close this out as I believe this has been answered well and in entirety – declarations are indeed not supposed to be imported and indeed would not produce valid ES modules. That is TS behavior and not specific to this plugin.

OP also suggested themselves that the issue was not with this plugin and has not responded to further comments.

Note that triple-slash directives may behave differently, which may be what OP intended to do instead?
