How to Reasonably Keep Your Tauri Commands Organized in Rust

When building Tauri applications, it's important to keep your codebase organized, especially as your project grows. Trust me, as someone who's relatively new to Rust, I've had my fair share of messy situations—spending hours digging myself out of self-made holes. If you're anything like me, you want to avoid that. So, let's talk about how to keep things neat by splitting your Tauri commands into separate files.

Start with a Commands Module

First things first, create a commands module. This will be the hub for all your Tauri commands. In your src directory, make a folder named commands. Inside this folder, you’ll create files for different groups of related commands. For instance:

• system_info.rs for system-related commands
• process_info.rs for commands dealing with processes
• greet.rs for something simple like a greeting command

Here’s what your directory might look like:

src/
│
├── commands/
│   ├── mod.rs
│   ├── system_info.rs
│   ├── process_info.rs
│   └── greet.rs
│
└── main.rs

Organize Commands into Separate Files

Now, go ahead and move your command functions into these respective files. By doing this, you’re breaking down your project into manageable chunks, making it easier to maintain. Plus, it’s a lot less intimidating when you need to revisit or expand a specific functionality.

Tie It All Together in mod.rs

Once your commands are in their own files, you need to make sure they’re accessible throughout your project. In the commands/mod.rs file, expose each command with pub mod statements.

pub mod greet;
pub mod system_info;
pub mod process_info;

Register Commands in main.rs

Finally, in your main.rs, import these commands and register them with Tauri’s Builder. This way, Tauri knows where to find your commands when you call them from the frontend.

mod commands;

fn main() {
    tauri::Builder::default()
        .invoke_handler(tauri::generate_handler![
            commands::greet::greet,
            commands::system_info::get_system_info,
            // Other commands...
        ])
        .run(tauri::generate_context!())
        .expect("error while running tauri application");
}

Wrapping Up

Keeping your Tauri commands organized in separate files is a small step that makes a big difference, especially as your project grows. By splitting your code into bite-sized pieces, you’ll save yourself from the chaos of an unorganized codebase. Trust me, your future self will thank you!
