Requesting reviews for capstone

[rallidars]

Hello!

This is my capstone project for the bootcamp, and I’m submitting it for review. The project is a network traffic monitoring tool built using Tauri and Yew, allowing users to observe network activity, filter by protocol, and import/export data.
Key Features:

Monitor network traffic in real-time.
Filter traffic by protocol for targeted analysis.
Import and export data seamlessly.
Combines a Rust backend with a web frontend for efficiency and security.
Your review is crucial for me to complete the bootcamp, and your feedback will be incredibly helpful in refining the final version.

Thank you so much for taking the time to review it!

.vscode/settings.json (1)

1-6: Emmet Configuration for Rust Files
This configuration sets up Emmet to treat Rust files as HTML. It’s a creative approach that can boost productivity when writing templated code in Rust (especially in the context of Tauri/Yew projects). Please ensure that this behavior is desired, as it might lead to unintended auto-expansion in non-template sections.

src-tauri/src/main.rs (1)

4-6: Main function simplicity with potential for error handling improvement.
The main function correctly delegates initialization to netwatch_lib::run(), which keeps the entry point minimal. Consider verifying that netwatch_lib::run() adequately handles errors or, if appropriate, add error handling here (e.g., using .expect(...) or proper logging) to capture startup failures.

package.json (1)

1-10: Missing script commands for development workflow.

The package.json lacks any npm scripts to help with development workflows (e.g., building CSS with Tailwind, starting development servers).

Consider adding scripts for common tasks:

{
  "devDependencies": {
    "autoprefixer": "^10.4.20",
    "postcss": "^8.5.3",
    "tailwindcss": "^3.4.17"
  },
  "dependencies": {
    "@tailwindcss/vite": "^4.0.8"
+ },
+ "scripts": {
+   "build:css": "tailwindcss -i ./styles/input.css -o ./styles/output.css",
+   "watch:css": "tailwindcss -i ./styles/input.css -o ./styles/output.css --watch"
  }
}

src/main.rs (2)

7-15: Enhance component formatting for clarity.

The HTML template has unnecessary whitespace that could be cleaned up for better readability.

#[function_component(App)]
fn app() -> Html {
    html! {
    <AppProvider>
        <Watch />
    </AppProvider>
-
    }
}

---

1-20: Consider adding documentation for the main application entry point.

As this is the entry point for your network monitoring tool, adding documentation about the overall application structure would be beneficial for future contributors.

+//! NetWatch - A network traffic monitoring tool built with Tauri and Yew
+//!
+//! This is the main entry point for the Yew-based frontend application.
+//! The application structure consists of:
+//! - AppProvider: Manages application state and theme
+//! - Watch: Main component for displaying network traffic data
+
 mod ui;

 use ui::app::Watch;
 use ui::components::AppProvider;
 use yew::{function_component, html, Html};

src-tauri/packets.json (1)

1-290: Consider adding a schema definition or documentation for the packet data structure.

The file contains sample network packet data but lacks any schema definition or documentation about the structure and purpose of the data.

Consider adding comments at the beginning of the file or a separate schema file that defines the expected structure, data types, and purpose of each field. This would make it easier for developers to understand and work with the data.

tailwind.config.js (2)

23-25: Improve font family configuration.

The font family configuration specifies 'Inter' but doesn't include any fallback fonts, which could cause display issues if 'Inter' isn't available.

Add fallback fonts to ensure consistent appearance across different systems:

      fontFamily:{
         'body': [
-    'Inter', ],
+    'Inter', 'system-ui', '-apple-system', 'BlinkMacSystemFont', 'Segoe UI', 'Roboto', 'Helvetica Neue', 'Arial', 'sans-serif' ],
      }

---

35-35: Optimize content configuration for better performance.

The current content pattern "./src/**/**/*.rs" is redundant. The double ** doesn't add any functionality beyond what a single ** provides.

Simplify the content pattern for better readability:

-  content: ["./src/**/**/*.rs"],
+  content: ["./src/**/*.rs"],

src-tauri/packets3.json (1)

17-17: Consider compression or encoding for binary payload data.

The payload_data fields contain lengthy hexadecimal and ASCII representations of binary data, making the JSON file unnecessarily large.

Consider either:

1. Storing binary data in Base64 format to reduce size
2. Using a more efficient format for storing packet captures
3. Providing an option to load payload data on demand rather than including it in the main data structure

Also applies to: 35-35, 53-53, 71-71, 89-89, 107-107, 125-125, 143-143, 161-161, 179-179, 197-197, 215-215, 233-233, 251-251, 269-269

src-tauri/tauri.conf.json (2)

28-34: Standardize icon path formats.

The icon paths use inconsistent formats, mixing relative paths with and without "../static/" prefix.

Standardize the icon path format for better maintainability:

    "icon": [
-      "../static/icon32x32.ico",
-      "../static/icons/icon128x128.ico",
+      "icons/icon32x32.ico",
+      "icons/icon128x128.ico",
      "icons/128x128@2x.png",
      "icons/icon.icns",
      "icons/icon.ico"
    ]

Alternatively, ensure all icon files are in the same relative location and use consistent path formats.

---

16-19: Consider adding more window configuration options.

The window configuration is minimal, specifying only title, width, and height.

For a better user experience, consider adding more window configuration options:

      {
        "title": "netwatch",
        "width": 800,
        "height": 600,
+        "minWidth": 640,
+        "minHeight": 480,
+        "resizable": true,
+        "fullscreen": false,
+        "center": true
      }

These additional properties will provide a more polished window management experience.

src-tauri/src/logic/import_export.rs (1)

9-25: Improve error handling in save_packets function.

The current implementation has a few areas that could be improved:

1. The use of unwrap() on line 17 could lead to a panic if the path is invalid
2. The error messages are informative but don't provide guidance on how to resolve issues
3. Consider returning more structured errors rather than string messages

 pub fn save_packets(
     packets: &VecDeque<FormatedPacket>,
     file_path: Option<FilePath>,
 ) -> Result<String, String> {
     match file_path {
         Some(path) => {
             let json_data = serde_json::to_string_pretty(&*packets)
                 .map_err(|e| format!("Failed to serialize packets: {}", e))?;
-            let mut file = File::create(&path.as_path().unwrap())
-                .map_err(|e| format!("Failed to create file: {}", e))?;
+            let path = path.as_path().ok_or_else(|| "Invalid file path".to_string())?;
+            let mut file = File::create(&path)
+                .map_err(|e| format!("Failed to create file: {}. Please check permissions and try again.", e))?;
             file.write_all(json_data.as_bytes())
-                .map_err(|e| format!("Failed to write to file: {}", e))?;
-            Ok(format!("File saved successfully to: {:?}", path))
+                .map_err(|e| format!("Failed to write to file: {}. Check disk space and permissions.", e))?;
+            Ok(format!("File saved successfully to: {:?}", path.display()))
         }
         None => Err("Save operation cancelled".to_string()),
     }
 }

src/ui/components/mod.rs (3)

15-18: Rename AuthProviderProps to AppProviderProps for consistency.

The struct is named AuthProviderProps but it's used for the AppProvider component. This naming inconsistency could cause confusion, especially as the application grows.

 #[derive(PartialEq, Properties)]
-pub struct AuthProviderProps {
+pub struct AppProviderProps {
     pub children: Children,
 }

---

20-43: Fix parameter type in AppProvider function and improve HTML structure.

The function uses AuthProviderProps which should be updated if you rename the struct as suggested above. Also, the HTML structure could be improved for better readability.

 #[function_component]
-pub fn AppProvider(props: &AuthProviderProps) -> Html {
+pub fn AppProvider(props: &AppProviderProps) -> Html {
     let theme: UseReducerHandle<ThemeState> = use_theme_context();
     let theme_cycle: Vec<&str> = vec!["light", "dark"];
     let interfaces = use_state(|| vec!["any".to_string()]);
     let interface = use_state(|| String::from("any"));
 
     html! {
         <ContextProvider<AppContext> context={AppContext {
             theme: theme.clone(),
             theme_cycle: theme_cycle,
             interfaces,
             interface
-
         }}>
-        <main class ={theme.current}>
+            <main class={theme.current}>
                 <div class="dark:bg-gray-900 min-h-screen">
-            { for props.children.iter() }
+                    { for props.children.iter() }
                 </div>
-        </main>
+            </main>
         </ContextProvider<AppContext>>
-
     }
 }

---

7-13: Add documentation comments to AppContext struct.

The AppContext struct is a central part of your application's state management. Adding documentation would help other developers understand its purpose and how to use it properly.

 #[derive(Clone, PartialEq)]
+/// Main application context shared across components
+/// 
+/// This struct holds the global application state including:
+/// - Theme state and available theme options
+/// - Available network interfaces
+/// - Currently selected interface
 pub struct AppContext {
     pub theme: UseReducerHandle<ThemeState>,
     pub theme_cycle: Vec<&'static str>,
     pub interfaces: UseStateHandle<Vec<String>>,
     pub interface: UseStateHandle<String>,
 }

src-tauri/Cargo.toml (1)

1-6: Update package metadata for public distribution.

The current metadata uses placeholder values ("A Tauri App" and "you"). Consider updating these fields with more specific information about your network monitoring application before publishing.

 [package]
 name = "netwatch"
 version = "0.1.0"
-description = "A Tauri App"
-authors = ["you"]
+description = "A network traffic monitoring tool built with Tauri and Yew"
+authors = ["JhonnyMahony <your.email@example.com>"]
 edition = "2021"

README.md (2)

36-38: Update contributing guidelines with more specific information.

20-23: Add more detailed runtime information.

The runtime section could be expanded to include more specific information about the application's behavior and required permissions for network monitoring.

 ## Running the Project
 
 - **Development Mode**: Run `yarn dev` to start the app in development mode with hot reloading.
-* **Runtime**: After building, the app runs on Windows, macOS, or Linux, depending on your platform.
+* **Runtime**: After building, the app runs on Windows, macOS, or Linux.

+  * **Windows**: Right-click and select "Run as administrator"
+  * **Linux/macOS**: Use `sudo` or run as root

Cargo.toml (2)

8-27: Dependencies look good but consider version constraints.

All necessary dependencies for a Yew-based Tauri application are included. The web-sys features list is appropriately scoped to just what you need.

Consider using more specific version constraints for critical dependencies like log and yew-hooks to prevent unexpected breaking changes in patch updates.

---

28-32: Remove unnecessary blank lines.

There are multiple consecutive blank lines that aren't needed.

styles/output.css (1)

1-1334: Auto-generated Tailwind CSS file looks good.

This appears to be an auto-generated Tailwind CSS output file. It contains all the necessary utility classes and styling for your application, including dark mode support and responsive design utilities.

Since this is a generated file, consider adding it to your .gitignore file if you're using a build process that regenerates it. This helps keep your repository clean and focused on source files rather than build artifacts.

src/ui/components/sidenavbar.rs (5)

14-32: Improve error handling when fetching interfaces.

The code currently silently ignores errors when fetching interfaces. Consider adding proper error handling and logging.

 use_async_with_options(
     {
         let app_context = app_context.clone();
         async move {
-            if let Ok(int) = serde_wasm_bindgen::from_value::<Vec<String>>(
-                invoke("get_interfaces", JsValue::NULL).await,
-            ) {
-                app_context.interfaces.set(int);
+            match serde_wasm_bindgen::from_value::<Vec<String>>(
+                invoke("get_interfaces", JsValue::NULL).await
+            ) {
+                Ok(int) => {
+                    app_context.interfaces.set(int);
+                    Ok(())
+                },
+                Err(e) => {
+                    log::error!("Failed to fetch interfaces: {:?}", e);
+                    Err(())
+                }
             }
-            Ok::<(), ()>(())
         }
     },
     UseAsyncOptions::enable_auto(),
 );

---

33-52: Simplify theme cycling logic.

The theme cycling logic is more complex than necessary. It can be simplified by using a modulo operation instead of finding the next theme in a cycle.

 let cycle_theme = {
     let app_context = app_context.clone();
     let current_theme: &str = app_context.theme.current;
-    let current_theme_index: usize = match app_context
-        .theme_cycle
-        .iter()
-        .position(|x: &&str| x == &current_theme)
-    {
-        Some(i) => i,
-        None => 0,
-    };
-    let next_theme: &str = match app_context.theme_cycle.iter().nth(current_theme_index + 1) {
-        Some(nt) => nt,
-        None => "light",
-    };
-    Callback::from(move |_| match next_theme {
-        "dark" => app_context.theme.dispatch(ThemeAction::Dark),
-        "light" | _ => app_context.theme.dispatch(ThemeAction::Light),
-    })
+    Callback::from(move |_| {
+        match current_theme {
+            "light" => app_context.theme.dispatch(ThemeAction::Dark),
+            "dark" | _ => app_context.theme.dispatch(ThemeAction::Light),
+        }
+    })
 }

---

72-81: Add validation for interface selection.

The interface selection logic doesn't validate if the selected interface is valid before updating the context.

 let on_change_interface = {
     let choosed_interface = choosed_interface.clone();
     let app_context = app_context.clone();
+    let interfaces = app_context.interfaces.clone();
     Callback::from(move |_| {
         if let Some(interface) = choosed_interface.cast::<HtmlSelectElement>() {
-            app_context.interface.set(interface.value())
+            let selected_value = interface.value();
+            // Validate that the interface exists or is "any"
+            if selected_value == "any" || interfaces.iter().any(|i| i == &selected_value) {
+                app_context.interface.set(selected_value);
+            } else {
+                log::warn!("Selected invalid interface: {}", selected_value);
+            }
         }
     })
 };

---

97-98: Use relative path for static assets.

The path to the logo image may be fragile. Consider using a more robust approach for loading static assets.

-<img src="../static/logo.png" class="h-12" alt="Flowbite Logo" />
+<img src="/static/logo.png" class="h-12" alt="NetWatch Logo" />

Also, update the alt text to match your application name instead of "Flowbite Logo".

---

122-138: Remove or implement commented-out code.

There's a large block of commented-out code for a sidebar implementation. Either implement it properly or remove it to improve code cleanliness.

Consider removing the commented code or moving it to a separate branch/issue if it's a work in progress.

src-tauri/src/lib.rs (3)

26-30: Consider removing or leveraging FilterState

FilterState is introduced but not currently used in the code. If it will be used in future expansions (e.g., for storing filter preferences globally), keep it. Otherwise, remove it to keep the code lean.

---

40-104: Improve error handling and concurrency in start_watch

1. The create_chanel function in the logic module panics on failure. Consider gracefully handling this error in production to avoid crashing the entire app.
2. The thread sleeps for 100ms in each loop iteration, which is acceptable for a small real-time capture tool. However, if performance requirements grow, revisit this approach (e.g., event-driven or smaller sleeps).
3. The concurrency model using AtomicBool and a Mutex<VecDeque<FormatedPacket>> is safe, but re-check for potential performance bottlenecks if the number of packets grows significantly.

---

113-138: Efficiency considerations for get_packets

Filtering the entire VecDeque each time might be acceptable for smaller traffic volumes. For larger volumes, consider a more efficient indexing or secondary structure for queries (e.g., storing per-protocol or per-IP indexes).

src/ui/components/theme.rs (3)

1-20: Potential error handling improvement for system preferences

The calls to expect could cause a panic in less common or restrictive browser/device environments (e.g., lacking window, or no match media support). Consider gracefully handling failures so the app can run without crashing.

---

86-95: Light icon component

Renders correctly. Try to keep CSS classes consistent—notice the duplicate "class" attribute on line 89 (class={handle_props_class(props)} and class="nav__svg light_svg"). Merging them into one can avoid potential CSS conflicts.

-<svg class={ handle_props_class(props) } width="1em" height="1em" viewBox="0 0 16 16" class="nav__svg light_svg" ...
+<svg class={ format!("{} nav__svg light_svg", handle_props_class(props)) } width="1em" height="1em" viewBox="0 0 16 16" ...

---

96-103: Dark icon component

Implementation mirrors the Light component. Same remark for merging class attributes applies here.

src-tauri/src/logic/show_packets.rs (5)

44-66: Constructor for FormatedPacket

1. Capturing the current time via chrono::Local is convenient.
2. A potential minor rename from lenght to length would align better with standard spelling.

-pub lenght: usize,
+pub length: usize,

---

68-106: get_payload_data for hex + ASCII conversion

A solid approach to present packet payload in a human-readable format. If performance becomes critical, consider a buffering mechanism to reduce string concatenations in tight loops.

---

228-230: get_icmp_type is unfinished

The todo!() placeholder means this is not implemented. If unneeded, remove it; otherwise, implement the missing logic or add a FIXME/TODO comment referencing future tasks.

Do you want me to supply a typical ICMP type mapping or open a new issue for this?

---

232-247: get_icmpv6_type enumerates common types well

Spelling note: Rouder advert is spelled incorrectly at line 238; consider “Router advert.”

-    Icmpv6Types::RouterAdvert => "Rouder advert".to_string(),
+    Icmpv6Types::RouterAdvert => "Router advert".to_string(),

---

266-321: parse_dns_packet is thorough

1. Returning an empty String when parsing fails is acceptable but hides errors from callers. Consider returning a Result<String, dns_parser::Error> or logging the parse failure.
2. The method for enumerating DNS record types is helpful for debugging.

src/ui/app.rs (5)

1-1: Remove unused import.

It appears HashMap is not utilized anywhere in this file. Removing it helps keep dependencies minimal and the code base cleaner.

-use std::collections::HashMap;

---

67-80: Consider robust error handling when fetching packets.

Currently, if an error occurs during the invoke("get_packets", ...) call, the code only checks for successful deserialization. For better resilience and debugging, handle possible backend errors explicitly (e.g., logging, user notifications, or retry logic) before defaulting to “Ok(())”.

---

82-102: Add user feedback or error handling for starting/stopping the watch.

When invoking stop_watch or start_watch, any error returned (e.g., from the backend) is ignored. Consider providing user feedback or logging in case the operation fails or is rejected, to improve usability and debuggability.

---

232-240: Enhance row click accessibility.

Using onclick alone on table rows may be less discoverable for keyboard or screen reader users who cannot “click” rows easily. Consider allowing focus or providing key events to improve usability.

---

52-57: Optional: Provide a higher-level API around invoke.

To isolate Tauri calls from the UI, consider wrapping invoke calls in error-handling utility functions. This approach allows the UI to remain cleaner and centralizes error-handling logic.

🔇 Additional comments (39)

src-tauri/.gitignore (1)

1-8: Targeted Ignore Rules for Compiled Artifacts and Schemas
The ignore file correctly excludes the /target/ directory (generated by Cargo) and /gen/schemas (generated by Tauri for auto-completion). This setup helps keep version control clean by ignoring build artifacts and generated files.

src-tauri/build.rs (1)

1-4: Minimal Build Script for Tauri
The build script succinctly calls tauri_build::build(), which is standard practice for Tauri applications. The code is clear and follows expected conventions. In case error handling becomes necessary, consider capturing the result or adding context to any build failures.

.taurignore (1)

1-3: Tauri Ignore Configuration
The file instructs the Taur build system to skip the /src, /public, and /Cargo.toml paths. This appears to be intended to prevent processing of frontend source code and configuration files that should not be handled by Taur. Just ensure that excluding /Cargo.toml is deliberate, as it may be needed for certain integrations.

.gitignore (1)

1-5: Root-Level Git Ignore Setup
The .gitignore entries correctly exclude directories such as /dist/, /target/, /node_modules/ and the Cargo.lock file—preventing unnecessary files from being tracked. This standard setup enhances repository cleanliness.

src-tauri/src/main.rs (1)

1-2: Effective Windows configuration and documentation.
The inline comment and the conditional compilation attribute on lines 1–2 clearly explain the purpose of suppressing the console window in release mode on Windows.

styles/input.css (1)

1-3: Clean inclusion of Tailwind directives.
The file neatly imports Tailwind’s base styles, components, and utilities, setting up the styling framework for the project seamlessly.

index.html (1)

1-13: Well-structured HTML for Tauri + Yew integration.
The HTML document is minimal and effective. It correctly defines the document structure, specifies metadata, and includes links to external directories and CSS for the application. The use of data-trunk attributes ensures proper file handling during build.

src/ui/mod.rs (1)

1-2: Clear modularization of UI components.
Declaring pub mod app; and pub mod components; organizes the UI logic into distinct modules, which should help maintain clarity and separation of concerns as the UI evolves.

.vscode/extensions.json (1)

1-3: Good recommendations for enhancing the development environment.
This configuration file suggests useful extensions for Tauri and Rust development, which will help contributors set up a more efficient workflow.

Trunk.toml (1)

1-9: Configuration looks good for Tauri and Yew integration.

The Trunk.toml configuration is appropriately set up for a Rust-based web frontend:

• Build target properly points to index.html
• Correctly ignores the Tauri directory to prevent unnecessary rebuilds
• Development server configured on port 1420, which is the default port Tauri expects

package.json (2)

✅ Verification successful

Verify package versions compatibility.

Some of the package versions specified may not exist or be compatible:

• postcss version ^8.5.3 appears to be ahead of the latest stable release (currently around 8.4.x)

---

🏁 Script executed:

#!/bin/bash
# Check if the specified postcss version exists
npm view postcss versions | grep 8.5.3

# Show latest available postcss version for reference
npm view postcss version

Length of output: 103

---

Package Version Compatibility Confirmed

The verification confirms that postcss version ^8.5.3 is valid and available:

• The npm registry shows versions 8.5.1, 8.5.2, and 8.5.3 are released.
• The latest version returned is 8.5.3.

No further action is needed based on this verification.

❌ Incorrect review comment

Verify Tailwind Vite integration package.

The @tailwindcss/vite package at version ^4.0.8 seems unusual. Typically, Tailwind integration with Vite is handled through the standard tailwindcss package and postcss configuration rather than a separate package.

---

🏁 Script executed:

#!/bin/bash
# Check if the @tailwindcss/vite package exists
npm view @tailwindcss/vite

# Show how Tailwind is typically integrated with Vite
npm view tailwindcss homepage

Length of output: 935

---

Integration Confirmed: @tailwindcss/vite is Officially Supported

After verification, it’s clear that the @tailwindcss/vite package is an official package maintained by the Tailwind CSS team (currently at version 4.0.15). Although traditional setups use the tailwindcss package with PostCSS, this package provides a valid, streamlined integration with Vite. No changes are required here.

Likely an incorrect or invalid review comment.

src-tauri/capabilities/default.json (1)

1-10: Basic Tauri capability configuration looks good.

The capabilities configuration properly defines permissions for the main window. This minimal setup allows basic Tauri functionality without exposing unnecessary system access.

src/main.rs (2)

1-6: Appropriate module structure and imports for Yew application.

The code correctly sets up the module structure and imports necessary components for a Yew-based application. The organization with separate ui modules is a good practice for maintainability.

---

17-20: Appropriate error handling and app initialization.

The main function properly sets up the panic hook for better error messages in the browser console and initializes the Yew renderer correctly.

src-tauri/packets.json (1)

10-17: Ensure sensitive network information is properly sanitized for sample data.

The packet data contains real MAC addresses, IP addresses, and network information which could potentially expose details about your network.

For sample data, consider replacing actual MAC addresses and IPs with documentation ranges (like 192.0.2.0/24 for IPv4). This prevents exposing real network topology information.

src/ui/components/mod.rs (1)

1-5: LGTM!

The imports and module declarations are well-organized and appropriate for the functionality implemented in this file.

src-tauri/Cargo.toml (1)

20-28:

Details

✅ Verification successful

Specify Tauri features and dependency version constraints.

The Tauri dependency is missing features that would be useful for a network monitoring application. Also, some dependencies have very specific version constraints while others don't.

🌐 Web query:

What features are available in Tauri v2 for network monitoring applications?

💡 Result:

Tauri v2 provides several features and plugins particularly useful for network monitoring applications, combining native capabilities with secure, cross-platform functionality:

Core Networking Features:

• HTTP Client - Built-in Rust-based HTTP client for efficient network requests[1][8][7]
• WebSocket Support - Plugin for establishing WebSocket connections with Rust backend[1][8]
• Port Scanning - Community tauri-plugin-network for scanning local network IPs and ports via HTTP[16]

Monitoring Utilities:

• Process Monitoring - Access system processes through process plugin[1][8]
• Network Interface Info - Read network interface details via tauri-plugin-network[16]
• Real-time Updates - IPC channels and event system for live data streaming[3][17]

Security & Control:

• Capability System - Granular permission control for network operations:
  • Platform-specific network rules (desktop vs mobile)[5][9][15]
  • Window/webview-specific network access[3][5]
  • Remote API whitelisting with scope constraints[5]

Infrastructure:

• Localhost Server - Production-ready local server for internal communications[1][8]
• CLI Integration - Parse network-related command-line arguments[1][8]
• Auto-Updates - Secure update mechanism through tauri-plugin-updater[11]

UX Enhancements:

• System Tray Integration - Background monitoring with tray icon[1][13]
• Notifications - Native OS alerts for network events[1][8][13]

Tauri Dependency and Dependency Version Consistency Update

After reviewing Tauri v2's capabilities for network monitoring, the proposed features ("shell-open", "dialog", "process") are appropriate—especially with the process plugin enabling access to system processes, a key requirement for network monitoring apps. The diff also cleans up formatting to ensure consistency across dependency version constraints and adds a suggestion for enhanced error handling via thiserror.

• Updated the Tauri dependency to include network-monitoring–focused features.
• Reformatted dependency declarations (e.g., spacing around "=") for consistency.
• Added a recommendation to include thiserror for better error handling.

 [dependencies]
- tauri = { version = "2", features = [] }
+ tauri = { version = "2", features = ["shell-open", "dialog", "process"] }
  tauri-plugin-opener = "2"
  serde = { version = "1", features = ["derive"] }
  serde_json = "1"
- pnet="0.35.0"
- chrono="0.4.39"
- log="0.4.0"
- dns-parser="0.8.0"
+ pnet = "0.35.0"
+ chrono = "0.4.39"
+ log = "0.4"
+ dns-parser = "0.8.0"
+
+ # Consider adding for better error handling:
+ thiserror = "1.0"

README.md (1)

1-3: LGTM!

The title and introduction effectively convey the purpose of the project and the technologies used.

Cargo.toml (1)

6-7: LGTM! Well-documented manifest file.

Good practice to include a reference link to the Cargo.toml documentation.

src-tauri/src/logic/mod.rs (1)

1-5: Good module structure and imports.

The module organization and imports are clean and well-structured. Importing the necessary components from pnet for network interface handling is appropriate.

src/ui/components/sidenavbar.rs (1)

8-12: LGTM! Properly defined WASM bindings for Tauri invocation.

The external function declaration for the Tauri invoke function is correctly set up.

src-tauri/src/lib.rs (4)

1-23: Clean and well-organized imports

These imports cleanly separate standard, third-party, and local modules, making them easy to follow. No issues noted here.

---

32-38: get_interfaces function is straightforward

Providing a simple list of network interfaces is good. Optionally, you could enhance it with error or empty-result handling (e.g., logging a warning if no interfaces are detected).

---

106-111: stop_watch command is straightforward

The usage of AtomicBool to halt packet capture is simple and direct. No issues noted here.

---

140-154: Proper Tauri entry point in run

The Tauri builder configuration is coherent. Managing shared state and plugging in necessary commands is neatly implemented.

src/ui/components/theme.rs (3)

21-31: Good use of a dedicated ThemeState struct

The separation of theme state into a dedicated struct is neat. It keeps logic modular and maintainable.

---

52-71: Persisting theme to LocalStorage is a nice UX touch

The Reducible implementation correctly updates the stored theme. Consider a more robust fallback if LocalStorage is not available (private/incognito modes).

---

73-85: Use of Props struct is clear

The Props struct and handle_props_class helper function are well-organized for customizing component classes.

src-tauri/src/logic/show_packets.rs (10)

33-42: DetailedInfo struct is well-defined

The struct holds helpful metadata. No immediate concerns regarding correctness or performance.

---

108-136: process_arp_packet handles ARP well

The function effectively increments its counter, extracts relevant addresses, and returns a properly constructed packet. The fallback Unknown operation is also a good catch.

---

138-158: process_ipv6_packet properly extracts IPv6 info

This looks correct and is structured similarly to the ARP handling. No issues noted.

---

160-180: process_ipv4_packet is consistent and readable

The IPv4 handling mirrors the IPv6 approach nicely. Logic is succinct and maintainable.

---

182-190: process_ip_traffic gracefully delegates to protocol-specific functions

This design elegantly centralizes the protocol branching logic.

---

192-204: process_tcp_packet: good detail extraction

Captures ports and flags. No major concerns.

---

206-213: process_udp_packet: straightforward port processing

Same pattern as TCP. No issues found.

---

215-220: process_icmp_packet: minimal but functional

Captures the ICMP type. No concerns.

---

221-226: process_icmpv6_packet: consistent with ICMP approach

Extracts the ICMPv6 type. Similar approach, no issues.

---

249-265: get_tcp_flags handles flag extraction effectively

The bitwise logic is compact and clear. This is a good approach.

⚠️ Potential issue

Fix typo in field name.

The field is spelled "lenght" instead of the correct "length" throughout the file.

This typo appears in every packet entry and should be corrected to ensure consistent data structure.

-    "lenght": 28,
+    "length": 28,

⚠️ Potential issue

Fix duplicate theme property in Tailwind configuration.

There are two theme declarations in this file. The second one (lines 36-38) will override the first one (lines 4-27), which contains your custom configurations.

Remove the second theme declaration or merge it with the first one to avoid losing your custom theme settings:

  content: ["./src/**/**/*.rs"],
-  theme: {
-    extend: {},
-  },
  plugins: [],

	plugins: [],

[coderabbitai]

⚠️ Potential issue

Fix "lenght" typo consistently throughout the file.

Similar to the first packets file, the field name "lenght" is misspelled and should be "length".

This typo needs to be corrected in all packet entries to maintain consistency and prevent potential issues when parsing the data.

-    "lenght": 28,
+    "length": 28,

Also applies to: 26-26, 44-44, 62-62, 80-80, 98-98, 116-116, 134-134, 152-152, 170-170, 188-188, 206-206, 224-224, 242-242, 260-260

[coderabbitai]

🛠️ Refactor suggestion

Standardize packet data files and consider using a structured format.

This file (packets3.json) contains similar data to packets.json but with more diverse protocols. Having multiple similar files can lead to maintenance challenges.

Consider one of the following approaches:

1. Merge packet data into a single file with a clear naming convention
2. Create a structured database or use a packet capture format (like PCAP) instead of raw JSON
3. Add metadata to clarify the purpose and relationship between different packet data files

[coderabbitai]

⚠️ Potential issue

Security concern: CSP is set to null.

Setting Content Security Policy (CSP) to null disables an important security feature that helps prevent cross-site scripting (XSS) attacks.

Implement a proper CSP that restricts content sources appropriately for your application. For example:

-      "csp": null
+      "csp": "default-src 'self'; script-src 'self'; connect-src 'self' http://localhost:*; img-src 'self' data:; style-src 'self' 'unsafe-inline';"

This policy allows resources only from your application while providing necessary exceptions for local development.

[coderabbitai]

⚠️ Potential issue

Fix function name typo and improve error handling.

The function name has a typo ("chanel" instead of "channel"), and it uses panic for error handling, which is not ideal for user-facing applications.

-pub fn create_chanel(
+pub fn create_channel(
     interface: NetworkInterface,
-) -> (Box<dyn DataLinkSender>, Box<dyn DataLinkReceiver>) {
+) -> Result<(Box<dyn DataLinkSender>, Box<dyn DataLinkReceiver>), String> {

⚠️ Potential issue

Verify string slicing safety for payload data.

The code slices line[0..4], line[4..55], and line[55..]. Any line shorter than 55 characters could trigger a panic. Add checks or conditionals to safely handle shorter lines.

Apply a conditional bound check before slicing lines:

-let offset = &line[0..4];
-let hex = &line[4..55].trim_end();
-let ascii = &line[55..].trim_end();
+let offset = line.get(0..4).unwrap_or_default();
