There is no SQLite in the browser, unless you are talking about something like https://github.com/kripken/sql.js, though that is very heavy and is in-memory only. There are a number of packages that provide an abstraction over IndexedDB, such as Dexie.js, AlaSQL, Nano-SQL, Lovefield, etc. Maybe have a look at their codebases to get a sense of the complexity involved.
