Hey Kotlin+WASM experts,

I want to compile a Kotlin library which will use SQLite to store and retrieve data. I want compilation target to be WASM. SQLite binaries are available as wasm files, how do I add that to my project? This library will be called from JS in browser.

Any pointers on how do I process are much appreciated.

IIUC you're looking to compile a Kotlin library which has a Kotlin API for access SQLite (in C++ implementation). Is the SQLite source already compiled or do you need to compile that to wasm as well?

[Thomas Nattestad]

We partnered with the SQLite team to add an officially supported wasm target so that you can use SQLite directly from a JS API - see instructions here https://developer.chrome.com/blog/sqlite-wasm-in-the-browser-backed-by-the-origin-private-file-system/

Would be curious if this meets your need or if you need it to be a Kotlin interface 🙂

Hey @Thomas Nattestad thanks for the reply.

I am using SQLite+OPFS in JS/TS already. But I was wondering how do I add that as a dependency so that SQLite api is accessible in Kotlin code.

val wasmMain by getting {
    dependsOn(commonMain)
    dependencies {
        implementation("<what goes here>")
    }
}

I want to bundle the resulting code again as wasm and ship it to browser to be consumed by JS.
