Tauri Configuration Files

Tauri v2 applications use three primary configuration files to manage application behavior, dependencies, and build processes.

Configuration File Overview

File	Purpose	Format
tauri.conf.json	Tauri-specific settings	JSON, JSON5, or TOML
Cargo.toml	Rust dependencies and metadata	TOML
package.json	Frontend dependencies and scripts	JSON

tauri.conf.json

The main configuration file located in src-tauri/. Defines application metadata, window behavior, bundling options, and plugin settings.

Supported Formats

• JSON (default): tauri.conf.json
• JSON5: tauri.conf.json5 (requires config-json5 Cargo feature)
• TOML: Tauri.toml (requires config-toml Cargo feature)

Bundle Targets by Platform

Platform	Targets

Platform-Specific Configuration

Create platform-specific files that override base configuration using JSON Merge Patch (RFC 7396).

Platform	Filename
Linux	tauri.linux.conf.json
Windows	tauri.windows.conf.json
macOS	tauri.macos.conf.json
Android	tauri.android.conf.json
iOS	tauri.ios.conf.json

Example src-tauri/tauri.windows.conf.json:

{
  "app": {
    "windows": [{ "title": "My App - Windows Edition" }]
  },
  "bundle": {
    "windows": { "nsis": { "installMode": "perMachine" } }
  }
}

Example src-tauri/tauri.macos.conf.json:

{
  "app": { "macOSPrivateApi": true },
  "bundle": {
    "macOS": { "minimumSystemVersion": "11.0", "entitlements": "entitlements.plist" }
  }
}

CLI Configuration Override

# Development with custom config
tauri dev --config src-tauri/tauri.dev.conf.json

# Build with beta configuration
tauri build --config src-tauri/tauri.beta.conf.json

# Inline configuration override
tauri build --config '{"bundle":{"identifier":"com.company.myapp.beta"}}'

Cargo.toml Configuration

Located in src-tauri/Cargo.toml, manages Rust dependencies.

[package]
name = "my-app"
version = "1.0.0"
edition = "2021"

[build-dependencies]
tauri-build = { version = "2.0", features = [] }

[dependencies]
serde = { version = "1.0", features = ["derive"] }
serde_json = "1.0"
tauri = { version = "2.0", features = [] }
tauri-plugin-shell = "2.0"
tauri-plugin-opener = "2.0"

[features]
default = ["custom-protocol"]
custom-protocol = ["tauri/custom-protocol"]

Common Tauri Features

[dependencies]
tauri = { version = "2.0", features = [
  "config-json5",      # Enable JSON5 config format
  "config-toml",       # Enable TOML config format
  "devtools",          # Enable WebView devtools
  "macos-private-api", # Enable macOS private APIs
  "tray-icon",         # Enable system tray support
  "image-png",         # PNG image support
  "image-ico",         # ICO image support
  "protocol-asset"     # Custom asset protocol
] }

Version Management

tauri = { version = "2.0" }       # Semver-compatible (recommended)
tauri = { version = "=2.0.0" }    # Exact version
tauri = { version = "~2.0.0" }    # Patch updates only

package.json Integration

{
  "name": "my-tauri-app",
  "version": "1.0.0",
  "scripts": {
    "dev": "vite",
    "build": "vite build",
    "tauri": "tauri"
  },
  "dependencies": { "@tauri-apps/api": "^2.0.0" },
  "devDependencies": { "@tauri-apps/cli": "^2.0.0" }
}

Environment-Specific Configurations

Development (src-tauri/tauri.dev.conf.json)

{
  "build": { "devUrl": "http://localhost:5173" },
  "app": {
    "withGlobalTauri": true,
    "windows": [{ "title": "My App [DEV]" }]
  }
}

Production (src-tauri/tauri.prod.conf.json)

{
  "build": { "frontendDist": "../dist", "removeUnusedCommands": true },
  "bundle": { "active": true, "targets": "all" }
}

Beta (src-tauri/tauri.beta.conf.json)

{
  "identifier": "com.company.myapp.beta",
  "productName": "MyApp Beta",
  "plugins": {
    "updater": {
      "endpoints": ["https://beta-releases.example.com/{{target}}/{{arch}}/{{current_version}}"]
    }
  }
}

TOML Configuration Format

When using Tauri.toml, configuration uses kebab-case:

[build]
dev-url = "http://localhost:3000"
before-dev-command = "npm run dev"
before-build-command = "npm run build"

[app]
with-global-tauri = false

[[app.windows]]
title = "My Application"
width = 1200
height = 800
resizable = true
center = true

[app.security]
freeze-prototype = false

[app.security.asset-protocol]
enable = true
scope = ["$APPDATA/**"]

[bundle]
active = true
targets = "all"
icon = ["icons/32x32.png", "icons/128x128.png", "icons/icon.icns", "icons/icon.ico"]

[plugins.updater]
pubkey = "YOUR_PUBLIC_KEY"
endpoints = ["https://releases.example.com/{{target}}/{{arch}}/{{current_version}}"]

Common Configuration Patterns

Multi-Window Application

{
  "app": {
    "windows": [
      { "label": "main", "title": "Main Window", "width": 1200, "height": 800, "url": "index.html" },
      { "label": "settings", "title": "Settings", "width": 600, "height": 400, "url": "settings.html", "visible": false }
    ]
  }
}

System Tray Application

{
  "app": {
    "trayIcon": { "id": "main-tray", "iconPath": "icons/tray.png", "iconAsTemplate": true },
    "windows": [{ "visible": false }]
  }
}

Plugin Configuration

{
  "plugins": {
    "updater": {
      "pubkey": "YOUR_PUBLIC_KEY",
      "endpoints": ["https://releases.example.com/{{target}}/{{arch}}/{{current_version}}"],
      "windows": { "installMode": "passive" }
    },
    "shell": {
      "open": true,
      "scope": [{ "name": "open-url", "cmd": "open", "args": [{ "validator": "\\S+" }] }]
    },
    "deep-link": {
      "mobile": ["myapp"],
      "desktop": { "schemes": ["myapp"] }
    }
  }
}

Lock Files

Commit lock files for reproducible builds:

File	Purpose
Cargo.lock	Locks Rust dependency versions
package-lock.json	Locks npm dependency versions
yarn.lock	Locks Yarn dependency versions
pnpm-lock.yaml	Locks pnpm dependency versions

Configuration Validation

Use the JSON schema for editor autocompletion:

{ "$schema": "https://schema.tauri.app/config/2" }

Run tauri info to verify configuration and environment setup.
