Service

Service is a simple Deno module for managing system services. It offers a convenient way to install, uninstall, and generate service configurations for various service managers.

If you want a fully featured process manager for Deno, we recommend using Pup.

Features

  • Easy-to-use CLI for managing services
  • Library usage through mod.ts for custom integrations
  • Install, uninstall, and generate service configurations
  • Compatible with systemd, sysvinit, docker-init, upstart (Linux) and launchd (macOS) service managers
  • Built for Deno, but usable to install any script as service on any system.

Installation

To use Service as a CLI program, you can install it using Deno:

deno install -fra --name service https://deno.land/x/service/service.ts

For library usage, simply import the installService() function from the mod.ts file:

import { installService } from "https://deno.land/x/service/mod.ts"

Note: Make sure to pin the import to a specific version, like service@1.0.0

CLI Usage

To use the service library from the command line, follow these steps:

  1. Install a command as a service:

    service install --name my-service --cmd "deno run --allow-net server.ts"

  2. Uninstall a service:

    service uninstall --name my-service

Programmatic Usage

To use the service library programmatically, you can import and use the installService and uninstallService functions.

InstallServiceOptions

This is the interface for the options used by the installService function:

interface InstallServiceOptions {
  system: boolean
  name: string
  cmd: string
  user?: string
  home?: string
  cwd?: string
}

The interface for the uninstallService function is very similar:

interface UnnstallServiceOptions {
  system: boolean
  name: string
  user?: string
  home?: string
  cwd?: string
}

installService

The installService function installs a command as a service, using the current service manager:

import { installService } from "https://deno.land/x/service/mod.ts"

await installService({
  system: false, // Use user mode (default) or system mode
  name: "my-service",
  cmd: "deno run --allow-net server.ts",
  user: "username", // Optional, defaults to current user
  home: "/home/username", // Optional, defaults to current user's home
  cwd: "/path/to/working/directory", // Optional, defaults to current working directory
})

uninstallService

The uninstallService function uninstalls a command from a service, using the currently installed service manager:

import { uninstallService } from "https://deno.land/x/service/mod.ts"

await uninstallService({
  system: false, // Use user mode (default) or system mode
  name: "my-service",
  user: "username", // Optional, defaults to current user
  home: "/home/username", // Optional, defaults to current user's home
  cwd: "/path/to/working/directory", // Optional, defaults to current working directory
})
