# DX Forge - Production VCS & Orchestration Engine


## Zero-bloat dependency management for the modern web


Forge is a production-ready version control system and orchestration engine that eliminates node_modules bloat by detecting code patterns via LSP and injecting only the components you actually use. Built for the DX tools ecosystem (dx-style, dx-ui, dx-icons, dx-fonts, dx-i18n, dx-check, dx-auth).

## 🚀 Key Features


- **🎯 Zero Bloat**: Only include code you actually use - no massive node_modules
- **⚡ LSP-Driven**: Detects `dxButton`, `dxiIcon` patterns via Language Server Protocol
- **🔄 Component Injection**: Fetches and injects components on-demand from R2 storage
- **🚦 Traffic Branch Safety**: Green (auto), Yellow (merge), Red (manual) deployment logic
- **🔧 Tool Orchestration**: Priority-based execution with dependency resolution
- **📦 Content-Addressable Storage**: SHA-256 blob storage with Git compatibility
- **🔍 Dual-Watcher**: LSP + File System monitoring with <100ms debounce
- **☁️ R2 Sync**: Zero-egress Cloudflare R2 cloud storage integration

## 🎯 Vision: Beat Node.js Bloat


Traditional JavaScript tooling installs **hundreds of megabytes** of dependencies you never use. Forge takes a radically different approach:

1. **LSP Detection**: Your editor already knows what code you write
2. **On-Demand Injection**: Fetch only `dxButton` when you type `dxButton`
3. **Self-Contained Tools**: Each DX tool knows what to do - Forge just says "Go!"
4. **Content-Addressable**: SHA-256 deduplication prevents duplicates
5. **R2 Cloud Sync**: Zero-egress storage with instant availability
6. **Simple Orchestration**: Forge detects changes, tools decide if they should run

**Result**: Install nothing. Use everything. Pay for nothing.

**Key Principle**: Forge is a dumb coordinator. Tools are smart and autonomous.

## 🏗️ Architecture


### Orchestration Engine


Forge coordinates multiple DX tools with priority-based execution and dependency resolution:

```rust
use dx_forge::{Orchestrator, DxTool};

let mut orchestrator = Orchestrator::new(".")?;
orchestrator.register_tool(Box::new(DxStyleTool));  // Priority: 100
orchestrator.register_tool(Box::new(DxUiTool));     // Priority: 80
orchestrator.register_tool(Box::new(DxIconsTool));  // Priority: 70
orchestrator.execute_all().await?;
```

### Dual-Watcher System


Monitors both Language Server Protocol events and file system changes:

```rust
use dx_forge::{DualWatcher, FileChange};

let watcher = DualWatcher::new(".")?;
let mut rx = watcher.subscribe();

while let Ok(change) = rx.recv().await {
    println!("Detected: {:?} via {:?}", change.path, change.source);
}
```

### Traffic Branch Safety


Three-tier update safety system prevents breaking changes:

- **🟢 Green**: Auto-update (CSS, docs, tests) - Zero friction
- **🟡 Yellow**: Merge required (components, logic) - Review conflicts
- **🔴 Red**: Manual resolution (APIs, types) - Breaking changes blocked

## 📦 Installation


Add to your `Cargo.toml`:

```toml
[dependencies]
dx-forge = "1.0"
tokio = { version = "1.48", features = ["full"] }
async-trait = "0.1"
anyhow = "1.0"
```

Or use the CLI:

```bash
cargo install dx-forge
forge --version
```

## 🚀 Quick Start Examples


### Building a DX Tool


Implement the `DxTool` trait to create a new tool:

```rust
use dx_forge::{DxTool, ExecutionContext, ToolOutput};
use async_trait::async_trait;
use anyhow::Result;

struct MyStyleTool;

#[async_trait]

impl DxTool for MyStyleTool {
    fn name(&self) -> &str { "dx-mystyle" }
    fn version(&self) -> &str { "1.0.0" }
    fn priority(&self) -> i32 { 100 }
    
    async fn execute(&self, ctx: &ExecutionContext) -> Result<ToolOutput> {
        // Process CSS files, inject styles, etc.
        Ok(ToolOutput::success("Styles injected"))
    }
}
```

### Monitoring File Changes


Use the dual-watcher to detect changes:

```rust
use dx_forge::DualWatcher;

#[tokio::main]

async fn main() -> anyhow::Result<()> {
    let watcher = DualWatcher::new("./src")?;
    let mut rx = watcher.subscribe();
    
    tokio::spawn(async move { watcher.start().await });
    
    while let Ok(change) = rx.recv().await {
        println!("📝 {} changed via {:?}", change.path.display(), change.source);
    }
    Ok(())
}
```

### Automatic Component Injection


Detect and inject components automatically:

```rust
// When user types: <dxButton>Click</dxButton>
// Forge detects via LSP, fetches from R2, injects:

import { dxButton } from '.dx/cache/dx-ui/Button.tsx';
// Component code injected with SHA-256 verification
```

## 🚀 Quick Start


### As a Library Dependency


Add to your `Cargo.toml`:

```toml
[dependencies]
forge = "1.0"
tokio = { version = "1.48", features = ["full"] }
```

### Basic Usage


```rust
use forge::{ForgeWatcher, ForgeEvent};

#[tokio::main]

async fn main() -> anyhow::Result<()> {
    // Create watcher for current directory
    let watcher = ForgeWatcher::new(".", false, vec![]).await?;

    // Run the watcher
    watcher.run().await?;
    Ok(())
}
```

### Running Examples


```bash
# Simple watcher example

cargo run --release --example simple

# Full CLI with all features

cargo run --release --bin forge
```

```bash
# Default mode (dual-watcher enabled)

cargo run --release

# Enable profiling to see timings

DX_WATCH_PROFILE=1 cargo run --release

# Disable rapid mode (quality only, for testing)

DX_DISABLE_RAPID_MODE=1 cargo run --release
```

## 🎯 Dual-Event System


Forge emits **two types of events** for every file change:

### 1. ⚡ Rapid Event (<35µs)


Ultra-fast notification using zero syscalls:

- **Timing**: Typically 1-2µs, max 35µs
- **Purpose**: Instant UI feedback for formatters/linters
- **Method**: Atomic sequence counter (no file I/O)
- **Data**: File path + timing only

### 2. ✨ Quality Event (<60µs)


Complete operation detection with details:

- **Timing**: Typically <60µs
- **Purpose**: Full analysis for quality tools
- **Method**: Memory-mapped I/O + SIMD diffs
- **Data**: Operations, line numbers, content changes

## Configuration


### Environment Variables


- `DX_WATCH_PROFILE=1` - Show detailed timing for both modes
- `DX_DISABLE_RAPID_MODE=1` - Disable rapid mode (quality only)
- `DX_DEBOUNCE_MS=1` - Debounce interval (default: 1ms)

### Performance Markers


- ⚡ RAPID mode ≤20µs (target achieved)
- 🐌 RAPID mode >20µs (needs optimization)
- ✨ QUALITY mode ≤60µs (target achieved)
- 🐢 QUALITY mode >60µs (needs optimization)

**Clean output - only shows when there are changes!**

Testing no-op detection...

## 📊 Performance Benchmarks

    Hello, Forge!
```

## � DX Tools Ecosystem

Forge orchestrates an entire ecosystem of zero-bloat tools:

| Tool | Purpose | Priority | Dependencies |
|------|---------|----------|--------------|
| **dx-style** | CSS injection & processing | 100 | - |
| **dx-fonts** | Font loading & optimization | 90 | dx-style |
| **dx-ui** | Component injection | 80 | dx-style, dx-fonts |
| **dx-icons** | Icon detection & injection | 70 | dx-ui |
| **dx-i18n** | Internationalization | 60 | dx-ui |
| **dx-charts** | Data visualization | 50 | dx-ui |
| **dx-forms** | Form validation | 40 | dx-ui |
| **dx-auth** | Authentication helpers | 30 | dx-ui |
| **dx-check** | Linting & validation | 10 | all |

### Self-Contained Tools

Each DX tool is autonomous and knows:

- What files it needs to process
- When it should run
- What patterns to detect
- How to inject code

```rust

```rust

Forge doesn't configure tools. It just calls them when file changes are detected.

```rust
// Tools register themselves with Forge
orchestrator.register_tool(Box::new(DxUiTool::new()));
orchestrator.register_tool(Box::new(DxStyleTool::new()));

// Forge detects changes and asks each tool: "Should you run?"
// Each tool decides based on its own logic
```

## ⚙️ Configuration


### Orchestration Config (`orchestration.toml`)


Define execution phases and tool coordination:

```toml
[orchestration]
version = "1.0"
parallel_execution = false
fail_fast = true

[phases.main]
tools = ["dx-style", "dx-ui", "dx-icons"]
parallel = false
required = true

[traffic]
enabled = true
auto_update_green = true
require_manual_red = true

[watcher]
enabled = true
debounce_ms = 100

[storage.r2]
bucket = "dx-forge-production"
endpoint = "https://storage.dx.tools"
```

### Zero Configuration


Tools configure themselves. Forge just detects changes and calls tools.

No manifest files needed. Tools are autonomous.

## � Performance


### Change Detection


- **LSP Events**: <10ms detection latency via Language Server Protocol
- **File System**: 100ms debounce prevents event storms
- **Blob Storage**: <5ms SHA-256 hashing and storage

### Traffic Analysis


- **Green Detection**: <1ms for safe patterns (`*.css`, `*.md`)
- **Yellow Analysis**: <50ms for merge conflict detection
- **Red Blocking**: <10ms for breaking change validation

### Component Injection


- **R2 Fetch**: <100ms (zero-egress bandwidth)
- **Cache Hit**: <1ms from local `.dx/cache/`
- **SHA Verify**: <2ms integrity check

### Tool Execution


- **Priority Sort**: <1ms dependency resolution
- **Parallel Safe**: Multiple tools run concurrently when independent
- **Rollback**: <50ms on execution failure
