Description

Hello 👋

I'm trying to use sql.js in my vscode extension. But getting this error:

"TypeError: Cannot set properties of undefined (setting 'exports')
    at /Users/dan/Projects/sql-ext-vscode/dist/extension.js:292298:395
        at new Promise (<anonymous>)
            at initSqlJs (/Users/dan/Projects/sql-ext-vscode/dist/extension.js:292227:24)

                            at async B0.m (file:///Users/dan/Soft/Visual%20Studio%20Code.app/Contents/Resources/app/out/vs/workbench/api/node/extensionHostProcess.js:114:4410)

My source code is

const SQL = await initSqlJs();
      if (fs.existsSync(dbPath)) {
        const fileBuffer = fs.readFileSync(dbPath);
        this.db = new SQL.Database(fileBuffer);
      } else {
        this.db = new SQL.Database();
      }

Maybe I'm doing something wrong?

Thank you!

Research direction

Start with the initSqlJs call and the bundled stack trace in dist/extension.js, then reproduce the failure in the VS Code extension environment. Check whether initialization completes before constructing SQL.Database for an existing or new database. Done means both database paths initialize without the reported TypeError.
