Windows Service for Deno

A Deno library that provides a simple way to create Windows services using Deno applications without any external tools.

Features

Run Deno applications as Windows services
React to events like “stop”, “pause”, and “continue” from the Windows Service Manager

Installation

To use the windows-service library in your project, add the following import statement:

import { WindowsService } from "https://deno.land/x/windows_service/mod.ts"

Usage

// Create a new WindowsService instance
const service = new WindowsService("MyDenoServiceWithCallbacks")

// Define the main function for your service
async function main() {
  console.log("Service started.")
  // Your service logic here...
}

// This is a request from the SCM to stop the service
exampleService.on("stop", () => {
  // Do stuff ...

  // Do stop the service
  // - This is done automatically if no handler for 'stop' event is defined.
  //   But included here for demonstration.
  exampleService.stop()
})

// Start the service, pass the main function
service.start(main)

For more details and examples, please refer to the example implementation.

Install the service with

sc.exe create my-test-service binPath= "c:\full\path\to\deno.exe run" -A --unstable --allow-ffi "C:/path/to/windows-service/example.ts"

Or compile it using

deno compile -A --unstable --allow-ffi example.ts --include dispatcher.js --output my-test-service.exe

And install using

sc.exe create my-test-service binPath= "C:/path/to/windows-service/my-test-service.ts"

Note that dispatcher.ts need to be included using --include at compile time, else the service worker wont work.

Note Both –unstable and –allow-ffi is required at the moment

Using `run.ts` as a Generic Service Runner

You can use the run.ts file as a generic service runner without downloading or installing anything. The file accepts command-line arguments for the service name, the --debug flag, and the command to run with its arguments after --.

To run the generic service runner with a command:

deno run -A --allow-ffi --unstable https://deno.land/x/windows_service/run.ts --serviceName your-service -- your_command your_arguments

If you want to debug (execute the command directly without the Windows service part), pass the --debug flag:

deno run -A --allow-ffi --unstable your_script.ts --serviceName your-service --debug -- your_command your_arguments

To install a service using this library and a generic command

sc.exe create your-service binPath= "c:/full/path/to/deno.exe run -A --unstable --allow-ffi https://deno.land/x/windows_service/run.ts --serviceName your-service -- your_command your_arguments"
