nodejs sqlite3 backup database

Question

I have to backup a sqlite database with nodejs (sqlite3 library). My strategy is to close the connection, copy database file and re-open the connection. The problem is that after the open all query/updates cause a SQLITE_MISUSE. I have only 1 connection in all the application. What is the problem? How can i backup database if the library (and all other nodejs libraries) doesn't allow to execute the native C backup apis)?

Answer 1

There's one way I can think of, by creating another database, attaching it to the current connection, and run a joint insert/select operation between them. This SO answer has some information on copying databases in SQLite, and see here for general information on attaching databases
