Hello! I’m trying to debug in browser my wasmJsMain and I have the following project structure:
• Project
◦ browserApp
◦ shared
◦ shared-ui

commonWebpackConfig {
        outputFileName = "browserApp.js"
        devServer = (devServer ?: KotlinWebpackConfig.DevServer()).apply {
            static = (static ?: mutableListOf()).apply {
                add(project.projectDir.path)
                add(project(":shared").projectDir.path)
                add(project(":shared-ui").projectDir.path)
            }
        }
    }
}

It only works for browserApp module, remaining files will throw: Could not load content for <http://localhost:8080/shared/src/commonMain/>.... (HTTP error: status code 404, net::ERR_HTTP_RESPONSE_CODE_FAILURE)

Whats missing? 🤔

Could you please try add something like this and check if it works:

add(project.rootDir.path)

[Guilherme Delgado]

I’ve tried that too and it doesn’t work 😞

[Guilherme Delgado]

Hum… strange if I have:

add(project.rootDir.path)
add(project.projectDir.path)

it works for all modules, but if I add only:

add(project.rootDir.path)

it works just for the other modules. Is it suppose to? 🤔

[Artem Kobzar]

It could be that for the executable module all the paths look like src/../../ instead of browserApp/src/../../

[Artem Kobzar]

So, yes, it seems like that it works as expected

[Artem Kobzar]

So, yep, just use those two paths.

[Guilherme Delgado]

Ok thanks 😊

[Guilherme Delgado]

one more: it debugs on Chrome but not on Firefox, it ignores break points

[Guilherme Delgado]

Should I open an issue or it’s a known issue?

[Artem Kobzar]

It's known issue and the problem is on the Firefox side. You can track it here: https://bugzilla.mozilla.org/show_bug.cgi?id=1871403

[Guilherme Delgado]

Thanks once again 😉

@Artem Kobzar
I also stumbled on this issue.
I started with a fresh project generated by Kotlin Multiplatform Wizard and followed instruction in article Debug Kotlin/Wasm code to add

add(project.projectDir.path + "/commonMain/")
        add(project.projectDir.path + "/wasmJsMain/")

but it’s not working.
While

add(project.rootDir.path)
add(project.projectDir.path)

works.

@Andraz thank you so much for sharing it. We will fix it in our tutorial and will add the snippet to the KMP wizard.
