Winservices

SlimIO Windows Services is a Node.js Binding which expose low-level Microsoft APIs to fetch Services state, configuration and triggers.

The binding expose the following methods/struct:

• ENUM_SERVICE_STATUS_PROCESS
• SERVICE_CONFIG
• SERVICE_TRIGGER_INFO
• EnumDependentServices

Requirements

• Node.js v12 or higher

Getting Started

This package is available in the Node Package Repository and can be easily installed with npm or yarn.

$ npm i @slimio/winservices
# or
$ yarn add @slimio/winservices

Usage example

Get all active windows services and retrieve advanced informations for each of them in series.

const services = require("@slimio/winservices");
const { States } = services.constants;

async function main() {
    const activeServices = await services.enumServicesStatus(States.Active);

    for (const service of activeServices) {
        console.log(`service name: ${service.name}`);
        const serviceConfig = await services.getServiceConfiguration(service.name);
        console.log(JSON.stringify(serviceConfig, null, 4));
        console.log("------------------------------\n");
    }
}
main().catch(console.error);

API

Enumerate Windows Services by the desirate state (Default equal to State.All). State can be retrieved with the constants State.

export interface ServiceStates {
    Active: 0,
    Inactive: 1,
    All: 2
}

The returned value is a Promise that contain an Array of Service.

export interface Service {
    name: string,
    displayName: string;
    process: {
        id?: number;
        name?: string;
        currentState: number;
        serviceType: number;
        checkPoint?: number;
        controlsAccepted: number;
        serviceFlags?: number;
        serviceSpecificExitCode: number;
        waitHint: number;
        win32ExitCode: number;
    };
}

Enumerate dependent Windows Services of a given Service name. The returned value is a Promise of Object DependentServices.

Default value for desiredState is State.All.

export interface DependentServices {
    [serviceName: string]: Service;
}

Warning: Each Service are a reducted version of the TypeScript interface Service (optionals are not in the payload).

Get a given Windows Service configuration. The returned value is a Promise of Object ServiceInformation.

export interface ServiceInformation {
    type: string;
    startType: string;
    errorControl: string;
    binaryPath: string;
    account: string;
    loadOrderGroup?: string;
    tagId?: number;
    dependencies?: string;
    description?: string;
}

Get all Service triggers for a given Service name. The returned value is a Promise that contain an Array of ServiceTrigger.

export interface ServiceTrigger {
    type: number;
    action: number;
    guid: string;
    dataItems: ServiceTriggerSpecificDataItem[]
}

export interface ServiceTriggerSpecificDataItem {
    dataType: number;
    data?: string;
}
