This plugin allows services to connect to a Turso database. Turso is an edge-hosted distributed database based on libSQL, a SQLite fork.

​
Usage

IMPORTANT: Currently Shuttle isn’t able to provision a Turso database for you (yet). This means you will have to create an account on their website and follow the few steps required to create a database and create a token to access it.
Add shuttle-turso and libsql to the dependencies for your service by running cargo add shuttle-turso libsql. This resource will be provided by adding the shuttle_turso::Turso attribute to your Shuttle main decorated function. It returns a libsql::Database. When running locally it will instantiate a local SQLite database of the name of your service instead of connecting to your edge database. If you want to connect to a remote database when running locally, you can specify the local_addr parameter. In that case, the token will be read from your Secrets.dev.toml file.

​
Parameters

ParameterTypeDefaultDescription
addrstr""URL of the database to connect to. Should begin with either libsql:// or https://.
tokenstr""The value of the token to authenticate against the Turso database. You can use string interpolation to read a secret from your Secret.toml file.
local_addrOptionNoneThe URL to use when running your service locally. If not provided, this will default to a local file named <service-name>.db

​
Example

In the case of an Axum server, your main function will look like this: 
use libsql::Database;
use shuttle_axum::ShuttleAxum;

#[shuttle_runtime::main]
async fn app(
#[shuttle_turso::Turso(
    addr="libsql://my-turso-db-name.turso.io",
	token="{secrets.DB_TURSO_TOKEN}")] client: Database,
// use secrets if you are not hardcoding your token/addr
#[shuttle_secrets::Secrets] secrets: SecretStore
) -> ShuttleAxum {
// ... some code
}
