Forge

Build cross-platform desktop apps with TypeScript and native capabilities as well as wasm, bundle and weld support.

Forge is an Electron-like desktop application framework using Rust and Deno. Apps are 100% TypeScript - no per-app Rust required. The runtime provides native system access through a secure, capability-based API.

Status: Alpha (v1.0.0p-steel-donut 🍩)

Features

• Native Performance - Rust runtime runtime with system WebViews (not Chromium)
• TypeScript First - Write app logic in TypeScript with full type support
• Capability Security - Explicit permission model for system access
• Cross-Platform - Build for macOS, Windows, and Linux from one codebase
• Multiple Frameworks - React, Vue, Svelte, or vanilla JS templates
• Hot Reload - Live updates during development

Installation

Quick Install (macOS/Linux)

curl -fsSL https://forge-deno.com/install.sh | sh

Manual Download

Download the latest release for your platform from GitHub Releases and extract to ~/.forge/bin/:

# Linux
tar -xzf forge-x86_64-unknown-linux-gnu.tar.gz -C ~/.forge/bin/

# macOS
tar -xzf forge-aarch64-apple-darwin.tar.gz -C ~/.forge/bin/

# Add to PATH (add to ~/.bashrc or ~/.zshrc)
export PATH="$HOME/.forge/bin:$PATH"

From Source (for contributors)

cargo install --path crates/forge_cli
cargo install --path crates/forge-runtime

Quick Start

# Copy an example to start a new app
cp -r examples/react-app my-app
cd my-app

# Run in development mode
forge dev .

# Build for production
forge build .
forge bundle .

Host Modules

Access native capabilities through runtime:* imports:

// Window management
import { openWindow, dialog, createTray } from "runtime:ui";

// File system
import { readTextFile, writeTextFile, watch } from "runtime:fs";

// Networking
import { fetchJson } from "runtime:net";

// System operations
import { clipboard, notify, info } from "runtime:sys";

// Process management
import { spawn } from "runtime:process";

Example

for await (const event of windowEvents()) {

  window.host.send("hello", { message: "Hi!" });
  window.host.on("update", (data) => console.log(data));

Development (For Contributors)

These commands are for developers contributing to the Forge framework itself. If you're building apps with Forge, you only need Deno - just use the forge CLI commands shown above.

# Build everything
cargo build --workspace

# Run tests
cargo test --workspace

# Run the example app
cargo run -p forge_cli -- dev examples/example-deno-app

# Build with release optimizations
cargo build --workspace --release

Requirements

For App Developers:

• Deno 1.40+

For Forge Contributors:

• Rust 1.70+
• Deno 1.40+
