@r1-runtime/cli

R1 TauriWeb Runtime CLI — migrate Tauri apps to the browser with one command.

Usage

# In your Tauri app directory
npx @r1-runtime/cli sync

What It Does

The CLI automatically migrates your Tauri app to work with R1:

1. ✅ Patches build.rs - Disables Tauri's native build process
2. ✅ Updates Cargo.toml - Adds WASM dependencies and configures library
3. ✅ Adds r1-macros - Enables #[r1::command] proc macro
4. ✅ Updates vite.config.ts - Adds R1 Vite plugin
5. ✅ Updates package.json - Installs R1 packages
6. ✅ Converts SQL imports - Patches Tauri SQL imports to R1 format
7. ✅ Creates backups - All modified files are backed up with .r1-backup extension

Example

# Create a Tauri app
npm create tauri-app@latest my-app -- --template react-ts --yes

# Migrate to R1
cd my-app
npx @r1-runtime/cli sync

# Build and run
npm install
npm run build
npx serve dist

What Gets Changed

build.rs

// Before: Complex Tauri build script
// After:
fn main() {}

Cargo.toml

# Adds:
[lib]
name = "your_app"
crate-type = ["cdylib", "rlib"]

[dependencies]
wasm-bindgen = "0.2"
serde = { version = "1", features = ["derive"] }
serde_json = "1"
r1-macros = "0.3.0"

# Moves native deps to:
[target.'cfg(not(target_arch = "wasm32"))'.dependencies]
tauri = "..."

vite.config.ts

import { r1Plugin } from '@r1-runtime/vite-plugin';

export default defineConfig({
  plugins: [
    r1Plugin({ rustSrc: './src-tauri' }),
    // ... other plugins
  ]
});

package.json

{
  "dependencies": {
    "@r1-runtime/core": "^0.3.0",
    "@r1-runtime/apis": "^0.3.0"
  },
  "devDependencies": {
    "@r1-runtime/vite-plugin": "^0.3.0"
  }
}

SQL Imports (if using SQL)

// Before:
import Database from "@tauri-apps/plugin-sql";

// After:
import { Database } from "@r1-runtime/apis/sql";

Backups

All modified files are backed up with .r1-backup extension:

• build.rs.r1-backup
• Cargo.toml.r1-backup
• vite.config.ts.r1-backup
• package.json.r1-backup

Requirements

• Node.js 18+
• Existing Tauri v1 or v2 project
• Rust toolchain (for building)

Troubleshooting

"No src-tauri/Cargo.toml found"

Make sure you're running the command in your Tauri app root directory (where package.json is).

"Command not found: r1"

Use npx @r1-runtime/cli sync instead of just r1 sync.

Build errors after migration

1. Run npm install to install R1 packages
2. Clear build cache: rm -rf target/ dist/
3. Rebuild: npm run build
