Initialize Tauri v2 + React scaffold with file-based routing and Tailwind v4 by Copilot · Pull Request #2 · LeagueToolkit/ltk-forge

Copilot · 2025-12-24T23:19:50Z

Scaffolds a Tauri v2 desktop application with React 19, TanStack Router file-based routing, Tailwind CSS v4, and modern tooling. Sets bundle identifier to com.leaguetoolkit.forge.

Stack

Desktop: Tauri v2.9 with Rust backend
Frontend: React 19 + Vite 7 + TypeScript 5.8
Routing: TanStack Router with file-based routes and automatic type generation
Styling: Tailwind CSS v4 via Vite plugin + Base UI components
Tooling: ESLint flat config, Prettier with Tailwind plugin
CI: GitHub Actions workflow (lint → typecheck → build)

export const Route = createFileRoute('/')({
  component: Index,
});

        Greet
      </Button>
    </main>
  );
}

Screenshots

Initial UI with Tailwind CSS and Base UI components:

Router Devtools active in development:

Scripts

pnpm dev          # Vite dev server (localhost:1420)
pnpm tauri dev    # Desktop app in dev mode
pnpm build        # Production build
pnpm lint         # ESLint
pnpm typecheck    # TypeScript validation
pnpm format       # Prettier

Note: pnpm tauri dev requires system dependencies (webkit2gtk on Linux, etc.). See Tauri prerequisites.

Original prompt

Create a complete scaffold for a Tauri v2 + React (Vite + TypeScript) desktop app in LeagueToolkit/ltk-forge.

Context:

There is an existing draft PR Initialize Tauri/React app with TanStack Router, Tailwind CSS v4, and tooling #1 intended for this work, but it currently contains 0 file changes.

Target bundle identifier: com.leaguetoolkit.forge.

Requirements

Tauri

Initialize Tauri v2 project structure including src-tauri/.

Ensure tauri.conf.json (or v2 equivalent) uses identifier/bundle id com.leaguetoolkit.forge.

Provide pnpm scripts to run Tauri dev/build.

Frontend

Use Vite + React + TypeScript.

Add TanStack Router with file-based routing and type generation enabled.

Configure the TanStack router Vite plugin.

Include a minimal working route structure: root route + index route.

Include router provider wiring in src/main.tsx.

Optionally include Router Devtools in development.

UI/Styling

Add @base-ui-components/react and create at least one example component usage in the UI.

Configure Tailwind CSS v4 using tailwindcss and @tailwindcss/vite.

Ensure Tailwind is active and working in the starter UI.

Linting/Formatting

Configure ESLint flat config (new ESLint config format).

Include TypeScript + React recommendations, React hooks, and React Refresh plugin for Vite.

Configure Prettier and include prettier-plugin-tailwindcss.

Add pnpm scripts:

lint, format, format:check, typecheck.

CI

Add a GitHub Actions workflow that runs on PRs and pushes to main.

Workflow should:

Set up Node and pnpm

Install dependencies

Run pnpm lint, pnpm typecheck, and pnpm build

Docs

Add/update a README.md with:

prerequisites

commands to run dev (frontend + tauri dev)

lint/format/typecheck commands

Acceptance criteria

pnpm install works.

pnpm dev runs the Vite frontend.

pnpm tauri dev runs the Tauri app.

pnpm lint, pnpm typecheck, pnpm build succeed.

Router typegen is functional (route tree generated/updated) and file-based routes resolve.

Notes

Keep structure at repository root (single app), not monorepo apps/.

Keep changes minimal but complete and consistent.

The HTML title "Tauri + React + Typescript" doesn't match the application name "LTK Forge" used throughout the rest of the codebase. This should be updated to "LTK Forge" for consistency with the product name defined in tauri.conf.json.

vite.config.ts

+// @ts-expect-error process is a nodejs global
+const host = process.env.TAURI_DEV_HOST;


The @ts-expect-error directive suppresses the error for process.env.TAURI_DEV_HOST, but this is a valid Node.js global in the Vite config context. Consider adding proper type definitions instead of suppressing the error, or use import.meta.env.TAURI_DEV_HOST if available in Tauri v2, as this would be more idiomatic for Vite projects.

+  },
+  "devDependencies": {
+    "@types/react": "^19.1.8",
+    "@types/react-dom": "^19.1.6",


The package.json lists React 19.1.0 as a dependency. React 19 is a relatively new major release that may have breaking changes and limited ecosystem support. Consider verifying that all dependencies (particularly @base-ui/react at rc.0) are fully compatible with React 19, or consider using React 18 LTS for better stability and ecosystem support.

The @base-ui/react package is at version 1.0.0-rc.0 (release candidate). Using pre-release versions in production can introduce instability and breaking changes. Consider either using a stable version or documenting that this is an experimental dependency that may require updates.

src-tauri/Cargo.toml

+# The `_lib` suffix may seem redundant but it is necessary
+# to make the lib name unique and wouldn't conflict with the bin name.
+# This seems to be only an issue on Windows, see https://github.com/rust-lang/cargo/issues/8519
+name = "ltk_forge_lib"


The library name in Cargo.toml uses an incorrect suffix. The comment states "The _lib suffix may seem redundant but it is necessary", but the actual name defined is "ltk_forge_lib" which doesn't match the expected binary name "ltk-forge" (note the underscore vs hyphen mismatch). According to the comment referencing the Windows issue, the lib name should be "ltk_forge_temp_lib" or similar to truly avoid conflicts, but it currently just mirrors the package name with underscores.

Suggested change

name = "ltk_forge_lib"

name = "ltk_forge_temp_lib"

src-tauri/src/main.rs

+#![cfg_attr(not(debug_assertions), windows_subsystem = "windows")]
+
+fn main() {
+    ltk_forge_temp_lib::run()


The main.rs file references "ltk_forge_temp_lib::run()" but the library is named "ltk_forge_lib" in Cargo.toml (line 14). This mismatch will cause a compilation error. The library name should be consistent between the Cargo.toml definition and the Rust code reference.
