**You can integrate DeepSeek‑Reasonix with any external system via subprocess calls, HTTP wrappers, direct Go package imports, or Python bridges—all through its single‑file binary core that exposes a minimal JSON API.**

DeepSeek‑Reasonix is a compact reasoning engine designed for seamless embedding into diverse tech stacks. In [`esengine/DeepSeek-Reasonix`](https://github.com/esengine/DeepSeek-Reasonix), the core logic resides in a single compiled binary that accepts JSON input and returns structured JSON output, making it language‑agnostic and deployment‑friendly.

## Architecture Overview

Understanding how to integrate DeepSeek‑Reasonix with other systems starts with its modular design. The repository separates concerns into a lightweight core, CLI wrapper, and optional UI layer.

| Component | Role | Source Location | Integration Method |
|-----------|------|----------------|------------------|
| **Reasonix core** | Executes reasoning loops, loads prompts, runs LLM inference | [[`desktop/workspace.go`](https://github.com/esengine/DeepSeek-Reasonix/blob/main/desktop/workspace.go)](https://github.com/esengine/DeepSeek-Reasonix/blob/main-v2/desktop/workspace.go) | Direct binary invocation or package import |
| **CLI wrapper** | Parses arguments, forwards to core, prints JSON | [[`cmd/signpath-contract/main.go`](https://github.com/esengine/DeepSeek-Reasonix/blob/main/cmd/signpath-contract/main.go)](https://github.com/esengine/DeepSeek-Reasonix/blob/main-v2/cmd/signpath-contract/main.go) | Subprocess calls from any language |
| **Workspace lease** | Provides safe concurrent access to workspace directories | [[`internal/workspacelease/lease.go`](https://github.com/esengine/DeepSeek-Reasonix/blob/main/internal/workspacelease/lease.go)](https://github.com/esengine/DeepSeek-Reasonix/blob/main-v2/internal/workspacelease/lease.go) | Go package import for synchronized operations |
| **Webview2 integration** | Desktop UI embedding (Electron‑like) | [[`desktop/webview2_runtime_other.go`](https://github.com/esengine/DeepSeek-Reasonix/blob/main/desktop/webview2_runtime_other.go)](https://github.com/esengine/DeepSeek-Reasonix/blob/main-v2/desktop/webview2_runtime_other.go) | UI‑only; backend API remains unchanged |

The **workspace lease** system is particularly critical for production integrations—it prevents race conditions when multiple services interact with the same Reasonix instance.

## Integration Pattern 1: Subprocess Invocation

The simplest way to integrate DeepSeek‑Reasonix with other systems is spawning the `reasonix` binary as a subprocess. Any language capable of process execution can use this pattern.

```bash

# Shell example: pass JSON via stdin

echo '{"prompt":"Explain quantum computing in 3 sentences","max_tokens":100}' \
    | reasonix --json

```

**Key characteristics:**
- Zero dependencies beyond the compiled binary
- JSON request/response protocol
- Suitable for shell scripts, Python, Node.js, Ruby, or any runtime

## Integration Pattern 2: HTTP Server Wrapper

For service‑oriented architectures, wrap the binary in a lightweight HTTP server. This pattern decouples clients from the Reasonix installation path.

```go
// Go HTTP wrapper (minimal implementation)
package main

import (
    "encoding/json"
    "net/http"
    "os/exec"
)

func main() {
    http.HandleFunc("/reason", func(w http.ResponseWriter, r *http.Request) {
        var req map[string]any
        json.NewDecoder(r.Body).Decode(&req)

        cmd := exec.Command("reasonix", "--json")
        stdin, _ := cmd.StdinPipe()
        json.NewEncoder(stdin).Encode(req)
        
        out, err := cmd.Output()
        if err != nil {
            http.Error(w, err.Error(), http.StatusInternalServerError)
            return
        }
        
        w.Header().Set("Content-Type", "application/json")
        w.Write(out)
    })
    http.ListenAndServe(":8080", nil)
}

```

Deploy this wrapper as a sidecar container or microservice—clients then interact via standard HTTP POST requests.

## Integration Pattern 3: Direct Go Package Import

When your service is built in Go, eliminate subprocess overhead by importing internal packages directly. This approach leverages the **workspace lease** system for safe concurrent access.

```go
package main

import (
    "fmt"
    "log"

    "github.com/esengine/DeepSeek-Reasonix/internal/workspacelease"
    "github.com/esengine/DeepSeek-Reasonix/desktop"
)

func main() {
    // Acquire exclusive workspace access
    lease, err := workspacelease.Acquire("./reasonix-workspace")
    if err != nil {
        log.Fatalf("lease acquisition failed: %v", err)
    }
    defer lease.Release() // Always release via defer

    cfg := desktop.PromptConfig{
        Prompt:      "Analyze this code for security vulnerabilities",
        MaxTokens:   512,
        Temperature: 0.3,
    }
    
    resp, err := desktop.RunPrompt(lease.Path(), cfg)
    if err != nil {
        log.Fatalf("inference failed: %v", err)
    }
    
    fmt.Println("Result:", resp.Text)
}

```

**Performance advantage:** Direct function calls avoid serialization and process spawn overhead—ideal for high‑throughput scenarios.

## Integration Pattern 4: Python Bridge via Subprocess

Python ecosystems can integrate DeepSeek‑Reasonix with other systems using the `subprocess` module. The benchmark suite includes a reference implementation in [[`benchmarks/e2e/tasks/diagnose-float-total/workdir/invoice.py`](https://github.com/esengine/DeepSeek-Reasonix/blob/main/benchmarks/e2e/tasks/diagnose-float-total/workdir/invoice.py)](https://github.com/esengine/DeepSeek-Reasonix/blob/main-v2/benchmarks/e2e/tasks/diagnose-float-total/workdir/invoice.py).

```python
import subprocess
import json

def reasonix(prompt: str, max_tokens: int = 256, temperature: float = 0.7) -> dict:
    """
    Call DeepSeek-Reasonix binary and return parsed JSON response.
    """
    payload = {
        "prompt": prompt,
        "max_tokens": max_tokens,
        "temperature": temperature
    }
    
    proc = subprocess.run(
        ["reasonix", "--json"],
        input=json.dumps(payload).encode(),
        capture_output=True,
        check=True
    )
    return json.loads(proc.stdout)

# Usage

result = reasonix(
    "Refactor this function to use list comprehensions",
    max_tokens=300
)
print(result["text"])

```

**Production consideration:** Implement retry logic and timeout handling around the subprocess call for resilience.

## Frequently Asked Questions

### Can DeepSeek‑Reasonix run as a persistent service?

Yes. Deploy the HTTP wrapper pattern behind a load balancer, or use the Go package import in a long‑running service with the workspace lease system managing concurrent requests. The binary itself is stateless—persistence occurs only in the workspace directory.

### What is the performance cost of subprocess invocation versus direct Go imports?

Subprocess calls incur ~10–50ms overhead for process spawn and JSON serialization. Direct Go imports eliminate this entirely. For latency‑sensitive applications, prefer the Go package import; for polyglot environments, the subprocess overhead is typically acceptable.

### Does the Webview2 integration affect API compatibility?

No. The [[`desktop/webview2_runtime_other.go`](https://github.com/esengine/DeepSeek-Reasonix/blob/main/desktop/webview2_runtime_other.go)](https://github.com/esengine/DeepSeek-Reasonix/blob/main-v2/desktop/webview2_runtime_other.go) file provides optional desktop UI capabilities, but the underlying binary interface remains identical. Non‑UI systems can safely ignore Webview2 dependencies.

### How do I handle concurrent requests from multiple services?

Use the **workspace lease** system implemented in [[`internal/workspacelease/lease.go`](https://github.com/esengine/DeepSeek-Reasonix/blob/main/internal/workspacelease/lease.go)](https://github.com/esengine/DeepSeek-Reasonix/blob/main-v2/internal/workspacelease/lease.go). Acquire a lease before each operation and release it afterward—this serializes access while maintaining safety across process boundaries.
