SQLite extensions
caution
SQLite extensions are an experimental feature in Turso. Your observations and feedback are welcome on our Discord.
SQLite extensions add optional features, supported by the SQLite community, that can be used in queries handled by the SQLite query engine. The instances of libSQL server managed by Turso can be configured to enable a select few extensions.
Enabling extensions
Extensions are enabled using the --enable-extensions flag when creating a
database with the Turso CLI. For example:
$ turso db create my-db --enable-extensions
Extensions can't be enabled for existing databases.
