Hi there, could you please provide a bit more information. At the first glance looks like it might anything 🙂
Probably that might be problem with modules. Which one are you using?

[kasper.kondzielski]

I am using commonjs but I tried also UMD, and it gives same error message

@Roman Artemev [JB] here is the binding file which I generated: https://github.com/CryptoVerseCC/http-claim-verifier-front/blob/js-formatter/src/main/kotlin/io/ghostbuster91/http/claim/verifier/front/json-formatter-js.kt

Actually the ts2kt was only generating me the binding for JSFormatterConfiguration interface, so I changed the declaration of JSFormatter in .d.ts file from class to interfase, and regenerated the biding

@kasper.kondzielski It seems you are using an NPM library, but the external declarations are marked with @JsNonModule annotations. That makes the compiler think that those classes could be referenced as is. What you probably want instead is `@JsModule`: https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.js/-js-module/index.html . This annotation lets you tell the compiler, which NPM package contains the declaration. As a result the compiler generates appropriate require calls and imports those classes.

Ok, I will try that, thanks!
