The official implementation is actually sqlite3, and there are at least 2 packages built on top of it -- sqlite and TypeORM. There are also other packages that can run SQLite including better-sqlite3 and sql.js.
Considerations
- Easy to write / maintain
- Client-side / browser only
- Fast
- Electron.js-enabled
In my experience, it seems that, in Node.js environment, Promise-based sqlite seems the be the best. Also, being-based on sqlite3, it works well with Electron.js (better-sqlite3 does not work well with Node.js. sql.js of course works, but it is not truly file-based.)
However, better-sqlite3 claims to be faster than sqlite...
Being a TypeScript user, I am looking forward to try out TypeORM sometime.
