There is a javascript library called sql.js that can do exactly what you want. In your case, you would use it like that

const db = new SQL.Database(new Uint8Array(buf));
const contents = db.exec("SELECT * FROM my_table");
// contents is now [{columns:['col1','col2',...], values:[[first row], [second row], ...]}]
