name: debug-tauri description: Automates Tauri WebView debugging using official plugins (tauri-plugin-log + screenshots) with process verification, automated screenshots, console logs, and state analysis. Use when debugging Tauri apps, investigating WebView issues, analyzing runtime errors, or troubleshooting UI problems.

Tauri WebView Debugger

Automated debugging workflow for Tauri applications using tauri-plugin-debug-tools with official plugin integration.

Prerequisites

• tauri-plugin-debug-tools installed and registered
• tauri-plugin-log (v2.0+): Official logging plugin for automatic console collection
• tauri-plugin-screenshots (v2.0+): Cross-platform screenshot capture
• Debug permissions enabled: debug-tools:default, log:default, screenshots:default
• Frontend logger initialized via attachConsole() (recommended for automatic log forwarding)

Quick Start

Run TAURI_APP_NAME=<app-binary-name> scripts/capture.sh to verify process and capture screenshot.

If process not found, start your dev server (e.g., tauri dev) and retry.

Debug Workflow

Copy this checklist to track progress:

Debug Progress:
- [ ] Step 1: Verify process status
- [ ] Step 2: Capture screenshot
- [ ] Step 3: Collect console logs
- [ ] Step 4: Capture WebView state
- [ ] Step 5: Analyze findings
- [ ] Step 6: Generate debug report
- [ ] Step 7: Propose fixes

Step 1: Verify Process Status

Run: TAURI_APP_NAME=<your-app> scripts/capture.sh

This checks if the app is running and captures an initial screenshot.

Step 2: Capture Screenshot

Via Plugin API (Recommended):

import { captureMainWindow } from "tauri-plugin-debug-tools/screenshotHelper";
const imagePath = await captureMainWindow();

Legacy: capture.sh script (macOS screencapture). See SCREENSHOTS.md for details.

Step 3: Collect Console Logs

Console Logger (Frontend - Recommended):

The consoleLogger automatically collects frontend logs and errors in a ring buffer and flushes them to a temp file.

// Import at app entry point to initialize automatic collection
import "tauri-plugin-debug-tools/consoleLogger";

// Use debugTools for explicit logging
import { debugTools } from "tauri-plugin-debug-tools/consoleLogger";
debugTools.log("App started");
debugTools.error("Something went wrong");

Finding consoleLogger Log Files:

import { invoke } from '@tauri-apps/api/core';

// Get actual log file path
const logPath = await invoke('plugin:debug-tools|reset_debug_logs');
console.log('Console logs stored at:', logPath);

Platform-specific consoleLogger locations:

• macOS: /tmp/tauri_console_logs_[app_name]_[pid].jsonl
• Linux: /tmp/tauri_console_logs_[app_name]_[pid].jsonl
• Windows: %TEMP%\tauri_console_logs_[app_name]_[pid].jsonl

Where [app_name] is the application name and [pid] is the process ID.

Backend Logs (tauri-plugin-log):

import { logger } from "tauri-plugin-debug-tools/logAdapter";

// Initialize once at app startup
const detach = await logger.initialize();

// Logs auto-forwarded to platform-specific location
logger.info("App started");
logger.error("Something went wrong");

Backend log locations:

• macOS: ~/Library/Logs/{bundle_id}/debug.log
• Linux: ~/.local/share/{bundle_id}/logs/debug.log
• Windows: {LOCALAPPDATA}\{bundle_id}\logs\debug.log

Alternative: Use debugBridge API. See IPC_COMMANDS.md for all methods.

Step 4: Capture WebView State

import { captureWebViewState } from "tauri-plugin-debug-tools/debugBridge";
const state = await captureWebViewState();

Returns: { url, title, user_agent, viewport }

Step 5: Analyze Findings

• Visual: Check screenshot for UI issues, errors, layout problems
• Logs: Review errors, warnings, patterns
• State: Verify URL, viewport, user agent
• Performance: Check for memory leaks, high CPU usage

Step 6: Generate Debug Report

Use template in REPORT_TEMPLATE.md.

Step 7: Propose Fixes

Based on collected evidence:

• Identify root cause
• Suggest specific code changes
• Provide implementation steps
