Getting Started

These instructions will show you how to use this package in your project. If you want to contribute, check Contributing.

Prerequisites

If you, for whatever reason, want to use this package fronted wise, it is possible since axios supports browsers. We also export CJS and ESM.

Installing

npm i divera247-api-unofficial

Usage

this is currently in the making! After installing the package you can use it as shown below.

Authorize

Retrieve the access token with user credentials (e.g. with a system user).

import {DiveraClient} from 'divera247-api-unofficial';
// CJS: const {DiveraClient} = require('divera247-api-unofficial');
try {
    const token = await DiveraClient.getAccessToken('username', 'password');
} catch (e) {
    // failed to retreive token
}

Declare the client

import {DiveraClient} from 'divera247-api-unofficial';
// CJS: const {DiveraClient} = require('divera247-api-unofficial');

const diveraClient = new DiveraClient(token);

Pull All (/v2/pull/all)

The pull all endpoint pretty much delivers everything there is for a tenant. This package includes some helpers to extract the data you need.

Read specific data Provide the path of the specific property you want to extract from the /pull/all response.

const {data: {user}} = await diveraClient.getAllByPath<{
  firstname: string;
  lastname: string;
}>('cluster', 'user');

Groups

import {
  DiveraResponse
} from "./divera-response.model";

const groups: DiveraResponse<Group[]> = await diveraClient.getGroups();

// Get Groups sorted by Divera provided `groupsorting`
const sortedGroups = await diveraClient.getGroups(true);

Alarm (/v2/alarms)

Create Alarm

The CreateAlarm model represents the payload to the Divera API. Alarm for the alarm details, Instructions to tell if the groups, vehicles etc are passed as id or name.

const alarm: CreateAlarm = {
    Alarm: {
        title: "This is an alarm!!!",
        group: [1234],
        ...
    },
    Instructions: {
        group: "id",
        ...
    }
}

A more convenient way is to use the builder:

const alarm = new AlarmBuilder()
  // set address of the scene
  .address('Foostreet 1337')
  // set coordinates (lat, lng) of the scene
  .coordinates(50.321, 10.123)
  // set units mapped by their ids
  .groups([1, 2, 3], 'id')
  .vehicles([1, 2, 3], 'id')
  // set a title, text and a type
  .details('title', 'description')
  // set prioity flag to true
  .isPriority()
  // send as push alarm
  .sendPush()
  // set foreign operation id (e.g. from external software)
  .foreignId('external id 123')
  // ...
  .build();

Retrieve alarms

const alarms = await diveraClient.getAlarms();
const alarm = await diveraClient.getAlarm("alarm id");

Create, Close, Archive and Delete an Alarm

// Create an alarm
const resp = await diveraClient.createAlarm(alarm);
// Close an alarm with an optional report
await diveraClient.closeAlarm(resp.data.id, 'some report');
// Archive an alarm
await diveraClient.archiveAlarm(resp.data.id);
// Delete the alarm
await diveraClient.deleteAlarm(resp.data.id);

Vehicles (/v2/using-vehicles)

Set Vehicle Status

const vehicleId = 1;
const vehicleStatus = 3;
const optionalPosition = {
  lat: 53.551086,
  lng: 9.993682,
};
await diveraClient.setVehicleStatus(
  vehicleId,
  vehicleStatus,
  'optional status note',
  optionalPosition,
);

Error handling

The package is non throwing for requests (except for getAccessToken). Every error will be represented as a DiveraResponse. The success is indicated with the success property. An error response is equivalent to the response from Divera. If the errors origin is the package, the error property will contain the error message.

Contributing

If you have a feature request, or you caught an error please create an issue.

If you want to create a new endpoint create a new folder under ./src/endpoints with the name of the root path of the endpoint and extend the BaseClient. Register the Endpoint Class in the index.ts file.
