File Saver App - Tauri Typing CST Test
File Saver App — Tauri Code
Demonstrates saving a text file using the Tauri FS API.
// main.js
import { writeFile } from '@tauri-apps/api/fs';
import { save } from '@tauri-apps/api/dialog';
document.getElementById('saveBtn').addEventListener('click', async () => {
const content = document.getElementById('input').value;
const filePath = await save({ defaultPath: 'note.txt' });
if (filePath) {
await writeFile({ path: filePath, contents: content });
alert('File saved!');
}
});

Tauri is an open-source framework for building tiny, secure, and fast desktop applications using web technologies (HTML, CSS, JS) while leveraging Rust for backend functionality. It works with frontend frameworks like React, Vue, Angular, and Svelte.
Primary Use Cases
- ▸Cross-platform desktop apps for Windows, macOS, and Linux
- ▸Electron alternative for smaller binaries and better security
- ▸Internal tools and utilities for businesses
- ▸Apps requiring frontend-backend separation
- ▸Desktop apps integrating web-based UI frameworks
Notable Features
- ▸Tiny binary sizes compared to Electron
- ▸Built-in security and sandboxing
- ▸Cross-platform support: Windows, macOS, Linux
- ▸Integration with any frontend framework
- ▸Rust backend for system-level access
Origin & Creator
Created by the Tauri Programme within the open-source community starting in 2019, Tauri was designed to offer lightweight, secure alternatives to Electron apps.
Industrial Note
Best suited for desktop apps that require small binary sizes, high performance, and strong security guarantees while reusing web development skills.
Quick Explain
- ▸Tauri allows building cross-platform desktop apps with minimal bundle size and high security.
- ▸It separates the frontend (web technologies) from the backend (Rust-based core).
- ▸Ideal for developers who want web-like development with native desktop capabilities.
Core Features
- ▸Webview-based frontend rendering
- ▸IPC (inter-process communication) between Rust backend and frontend
- ▸File system, OS APIs, and secure storage access
- ▸Bundling and signing for multiple platforms
- ▸Hot reloading for frontend development
Learning Path
- ▸Learn web frontend framework (React/Vue/Angular/Svelte)
- ▸Learn Rust basics
- ▸Understand Tauri CLI and commands
- ▸Build simple Tauri desktop apps
- ▸Package and distribute cross-platform apps
Practical Examples
- ▸Cross-platform note-taking apps
- ▸Productivity desktop utilities
- ▸Internal enterprise tools
- ▸Electron alternatives with smaller size and higher security
- ▸Desktop apps integrating cloud or local storage with frontend UI
Comparisons
- ▸Tauri vs Electron: Tauri has smaller binaries and Rust backend, Electron uses Node.js/Chromium
- ▸Tauri vs Flutter Desktop: Flutter compiles UI natively, Tauri uses web frontend
- ▸Tauri vs NW.js: Tauri focuses on security and small size, NW.js is Node.js/Chromium-based
- ▸Tauri emphasizes lightweight, secure desktop apps
- ▸Performance depends on frontend complexity and Rust backend efficiency
Strengths
- ▸Small app size (a few MBs)
- ▸High performance and native feel
- ▸Strong security by default
- ▸Frontend agnostic-works with React, Vue, Angular, Svelte
- ▸Rust-based backend ensures memory safety and concurrency
Limitations
- ▸Requires Rust knowledge for backend customizations
- ▸Smaller community than Electron
- ▸Some native APIs may require manual bindings
- ▸Not ideal for apps needing heavy graphics rendering
- ▸Limited ecosystem of plugins compared to Electron
When NOT to Use
- ▸Apps requiring heavy GPU rendering
- ▸Projects without web frontend skills
- ▸Apps needing large-scale native UI frameworks
- ▸Teams unfamiliar with Rust or Node.js
- ▸Complex multimedia-heavy desktop applications
Cheat Sheet
- ▸`tauri init` - initialize Tauri project
- ▸`tauri dev` - run app in development
- ▸`tauri build` - package app for production
- ▸`invoke('commandName')` - call Rust command from frontend
- ▸`tauri.conf.json` - configuration file for app settings
FAQ
- ▸Does Tauri support React, Vue, Angular, Svelte?
- ▸Yes, frontend framework agnostic.
- ▸Are Tauri apps secure?
- ▸Yes, security-first design with sandboxing and policies.
- ▸Is Rust mandatory?
- ▸Yes, for backend commands, but simple apps can use minimal Rust.
- ▸Can I build for all desktop platforms?
- ▸Yes, Windows, macOS, and Linux are supported.
- ▸Are Tauri apps smaller than Electron?
- ▸Yes, typically 3-10 MB compared to >50 MB for Electron apps.
