Configuration

The Tauri configuration object. It is read from a file where you can define your frontend assets, configure the bundler and define a tray icon.

The configuration file is generated by the tauri init command that lives in your Tauri application source directory (src-tauri).

Once generated, you may modify it at will to customize your Tauri application.

File Formats

By default, the configuration is defined as a JSON file named tauri.conf.json.

Tauri also supports JSON5 and TOML files via the config-json5 and config-toml Cargo features, respectively. The JSON5 file name must be either tauri.conf.json or tauri.conf.json5. The TOML file name is Tauri.toml.

Platform-Specific Configuration

In addition to the default configuration file, Tauri can read a platform-specific configuration from tauri.linux.conf.json, tauri.windows.conf.json, tauri.macos.conf.json, tauri.android.conf.json and tauri.ios.conf.json (or Tauri.linux.toml, Tauri.windows.toml, Tauri.macos.toml, Tauri.android.toml and Tauri.ios.toml if the Tauri.toml format is used), which gets merged with the main configuration object.

Configuration Structure

The configuration is composed of the following objects:

app: The Tauri configuration - build: The build configuration - bundle: The bundle configurations - plugins: The plugins configuration

devUrl

string | null formatted as uri

The URL to load in development.

This is usually an URL to a dev server, which serves your application assets with hot-reload and HMR. Most modern JavaScript bundlers like vite provides a way to start a dev server by default.

If you don’t have a dev server or don’t want to use one, ignore this option and use frontendDist and point to a web assets directory, and Tauri CLI will run its built-in dev server and provide a simple hot-reload experience.

features

string[] | null

Features passed to cargo commands.

frontendDist

FrontendDist | null

The path to the application assets (usually the dist folder of your javascript bundler) or a URL that could be either a custom protocol registered in the tauri app (for example: myprotocol://) or a remote URL (for example: https://site.com/app).

When a path relative to the configuration file is provided, it is read recursively and all files are embedded in the application binary. Tauri then looks for an index.html and serves it as the default entry point for your application.

You can also provide a list of paths to be embedded, which allows granular control over what files are added to the binary. In this case, all files are added to the root and you must reference it that way in your HTML files.

When a URL is provided, the application won’t have bundled assets and the application will load that URL by default.

runner

string | null

The binary used to build and run the application.

“my-binary-x86_64-pc-windows-msvc.exe” for Windows - “my-binary-x86_64-apple-darwin” for macOS - “my-binary-x86_64-unknown-linux-gnu” for Linux

csp

Csp | null

The Content Security Policy that will be injected on all HTML files on the built application. If dev_csp is not specified, this value is also injected on dev.

This is a really important part of the configuration since it helps you ensure your WebView is secured. See <https://developer.mozilla.org/en-US/docs/Web/HTTP/CSP>.

dangerousDisableAssetCspModification

DisabledCspModificationKind

Disables the Tauri-injected CSP sources.

At compile time, Tauri parses all the frontend assets and changes the Content-Security-Policy to only allow loading of your own scripts and styles by injecting nonce and hash sources. This stricts your CSP, which may introduce issues when using along with other flexing sources.

This configuration option allows both a boolean and a list of strings as value. A boolean instructs Tauri to disable the injection for all CSP injections, and a list of strings indicates the CSP directives that Tauri cannot inject.

WARNING: Only disable this if you know what you are doing and have properly configured the CSP. Your application might be vulnerable to XSS attacks without this Tauri protection.

devCsp

Csp | null

The Content Security Policy that will be injected on all HTML files on development.

This is a really important part of the configuration since it helps you ensure your WebView is secured. See <https://developer.mozilla.org/en-US/docs/Web/HTTP/CSP>.

TitleBarStyle

One of the following:

"Visible" A normal title bar.
"Transparent" Makes the title bar transparent, so the window background color is shown instead. Useful if you don’t need to have actual HTML under the title bar. This lets you avoid the caveats of using TitleBarStyle::Overlay. Will be more useful when Tauri lets you set a custom window background color.
"Overlay" Shows the title bar as a transparent overlay over the window’s content. Keep in mind: - The height of the title bar is different on different OS versions, which can lead to window the controls and title not being where you don’t expect. - You need to define a custom drag region to make your window draggable, however due to a limitation you can’t drag the window when it’s not in focus <https://github.com/tauri-apps/tauri/issues/4316>. - The color of the window title depends on the system theme.
