Debugging
With all the moving pieces in Tauri, you may run into a problem that requires debugging. There are many locations where error details are printed, and Tauri includes some tools to make the debugging process more straightforward.
Rust Console
The first place to look for errors is in the Rust Console. This is in the terminal where you ran, e.g., Tauri dev. You can use the following code to print something to that console from within a Rust file:
println!("Message from Rust: {}", msg);
Sometimes you may have an error in your Rust code, and the Rust compiler can give you lots of information. If, for example, tauri dev crashes, you can rerun it like this on Linux and macOS:
RUST_DEBUG=1 tauri dev
or like this on MS Windows:
set RUST_DEBUG=1
tauri dev
This command gives you a granular stack trace. Generally speaking, the Rust compiler helps you by giving you detailed information about the issue, such as:
error[E0425]: cannot find value `sun` in this scope
--> src/main.rs:11:5
|
11 | sun += i.to_string().parse::<u64>().unwrap();
| ^^^ help: a local variable with a similar name exists: `sum`
error: aborting due to previous error
For more information about this error, try `rustc --explain E0425`.
WebView JS Console
Right-click in the WebView, and choose Inspect Element. This opens up a web-inspector similar to the Chrome or Firefox dev tools you are used to.
Create a Debug Build
There are cases where you might need to inspect the JS console in the final bundle, so Tauri provides a simple command to create a debugging bundle:
Like the normal build and dev processes, building takes some time the first time you run this command but is significantly faster on subsequent runs.
The final bundled app has the development console enabled and is placed in src-tauri/target/debug/bundle.
Run Your App From the Terminal
You can also run a built app from the terminal, giving you the Rust compiler notes (in case of errors) or your println messages. Just find the file src-tauri/target/(release|debug)/[app name] and either double click it (but be warned, the terminal closes on errors) or just run it in directly in your console.
