Quick Reference
Migration CLI Command
npx @tauri-apps/cli migrate
This auto-converts v1 allowlist entries to capability files, updates Cargo dependencies, and restructures configuration. ALWAYS run this first before manual migration.

Critical Warnings
NEVER skip running npx @tauri-apps/cli migrate -- manual migration is error-prone and the CLI handles most conversions automatically.
NEVER forget to implement update UI -- Tauri v2 removed the automatic update dialog. Without explicit update checking code, users will NEVER receive updates.
NEVER use old import paths after migration -- @tauri-apps/api/tauri is now @tauri-apps/api/core; module-specific APIs moved to plugin packages.
NEVER use "v1Compatible" for createUpdaterArtifacts in new projects -- only use it when migrating existing installations from v1 updater.
ALWAYS restructure for mobile support if targeting mobile -- split main.rs into lib.rs + main.rs with #[cfg_attr(mobile, tauri::mobile_entry_point)].
ALWAYS add core permissions to capabilities -- v2 requires explicit permissions even for core features (windows, events, paths).

Mobile Restructuring
If targeting mobile, restructure the Rust entry point:
Before (v1 style, desktop only):
// src-tauri/src/main.rs
fn main() {
tauri::Builder::default()
.invoke_handler(tauri::generate_handler![])
.run(tauri::generate_context!())
.expect("error running app");
}
After (v2 style, desktop + mobile):
// src-tauri/src/lib.rs
#[cfg_attr(mobile, tauri::mobile_entry_point)]
pub fn run() {
tauri::Builder::default()
.invoke_handler(tauri::generate_handler![])
.run(tauri::generate_context!())
.expect("error running app");
}
// src-tauri/src/main.rs (minimal)
fn main() {
app_lib::run();
}
Cargo.toml for mobile:
[lib]
name = "app_lib"
crate-type = ["staticlib", "cdylib", "rlib"]
