Migration

You can define migrations to change the structure of your stores between versions. This is the recommended way to remove key-value pairs from a store.

src-tauri/src/lib.rs

rust

use tauri_plugin_svelte::Migration;

tauri_plugin_svelte::Builder::new()
  .migrations([v1(), v2(), v3()])
  .build();

fn v1() -> Migration {
  Migration::new("1.0.0", |state| {
    state.set("foo", "hello");
    Ok(())
  })
}

fn v2() -> Migration {
  Migration::new("2.0.0", |state| {
    state.remove("foo");
    state.set("bar", "你好");
    Ok(())
  })
}

fn v3() -> Migration {
  Migration::new("3.0.0", |state| {
    state.clear();
    state.set("baz", "olá");
    Ok(())
  })
}
