Unable to load db file from Wasm/StackBlitz

Hello,

I'm trying to create a full-stack project that will both contain the DB itself and the front-end with a back-office and a client-facing web-app. I thought trying to use libsql for this would be appropriate.

I tried to get started using StackBlitz's Bolt platform to generate a Next.js project but quickly ran into this error:

Module not found: Can't resolve './'

https://nextjs.org/docs/messages/module-not-found

Import trace for requested module:
./node_modules/@libsql/client/node_modules/@libsql/libsql-wasm-experimental/node.mjs
./node_modules/@libsql/client/lib-esm/wasm.js
./lib/db.ts
./app/page.tsx

In db.ts I create a file database using @libsql/client and in app/page.tsx I call the db to retrieve resources to render. Here is a light reproduction → from the Next.js starter on StackBlitz.

I tried to fix it by using an in-memory db or importing from @libsql/client-wasm to no avail. Then, I started from scratch, saw that this libsql demo on StackBlitz → is working and tried to build from there.

What I can't understand is where the db file is stored? Trying to initialize the client with a local file works outside of Wasm but on StackBlitz it always fails with this error: (StackBlitz →)

Error: SQLITE_CANTOPEN: sqlite3 result code 14: unable to open database file
    at async ModuleLoader.import (https://nodezjhahv-rpb4.w-credentialless-staticblitz.com/builtins.ddb8d84d.js:154:2688)
    at async loadESM (https://nodezjhahv-rpb4.w-credentialless-staticblitz.com/builtins.ddb8d84d.js:184:541)
    at async handleMainPromise (https://nodezjhahv-rpb4.w-credentialless-staticblitz.com/builtins.ddb8d84d.js:165:296) {
  resultCode: 14,
  name: 'SQLite3Error'
}

I feel like these are two intertwined issues as they involve the way the package works with Wasm environments.

Possibly related issues:

• #159 StackBlitz support?
• I also saw another still open issue that said the Wasm code wasn't bundled yet but can't find it again, and it does seem to be bundled.

Environment

• @libsql/client: 0.14.0 (@libsql/client-wasm)
• next: 13.5.1
• node: v18.20.3

Thanks in advance for your help!

Start with the linked StackBlitz reproductions and inspect lib/db.ts, app/page.tsx, and the @libsql client WASM entry points shown in the import trace. Reproduce both the module-resolution and SQLITE_CANTOPEN errors, then identify whether the failure is caused by bundling or local database-file access; done means the cause and a supported fix or limitation are documented.
