EXE Service — Documentation

EXE Service — a GUI utility that turns any EXE file into a Windows service in three clicks. Configure via JSON: startup parameters, logging, auto-restart, and JS scripts for notifications (Email/Slack/Telegram). Works through the standard Windows SCM — no wrappers needed. Ideal for Nginx, Syncthing, backends, and monitoring.

JsN

JsN.exe is a lightweight engine for running JavaScript scripts oriented for services. It has access to native Windows APIs: process monitoring, service management, HTTP requests, and email sending.

Contents

File Description
Configuration Config format, running
Process API Process monitoring and management
Service API Windows service management
HTTP API HTTP requests (GET / POST)
Email API Email sending (SMTP)
Examples Ready-made examples: Discord, Slack, Telegram, monitoring

Quick start

1. Create a JSON config

{
  "scriptfile": "./my_script.js",
  "arg": {
    "process_name": "notepad.exe"
  }
}

2. Write a script

// my_script.js
let f = proc_find(arg.process_name);
if (f.found) {
    let cpu = proc_cpu(f.pid);
    let ram = proc_ram(f.pid);
    console.log("PID:", f.pid);
    console.log("CPU:", cpu.cpu.toFixed(1) + "%");
    console.log("RAM:", ram.ram_mb.toFixed(1) + " MB");
} else {
    console.log("Process not found");
}

3. Run

JsN.exe my_config.json

Available functions by module

Module Functions Requires admin
Process monitoring proc_find, proc_cpu, proc_ram, proc_alive, proc_service —
Process management proc_kill, proc_run —
Windows services svc_status, svc_start, svc_stop, svc_restart ✓
HTTP http_get, http_post —
Email send_email —

The arg variable

All content of the "arg" field from the JSON config is available in the script as a global object arg:

{ "arg": { "host": "smtp.example.com", "port": 587 } }
console.log(arg.host);  // "smtp.example.com"
console.log(arg.port);  // 587

Result pattern

All functions return an object. On success error is an empty string; on failure it contains a description:

let r = proc_kill(1234);
if (r.ok) {
    console.log("Done");
} else {
    console.log("Error:", r.error);
}
