Agrarmonitor Connector

TypeScript MVP connector for Agrarmonitor with shared cookie persistence, optional AES-GCM cookie encryption, automatic login, retry after expired sessions, device registration checks, and customer detail extraction.

Installation

npm install

Build

npm run build

Example

import {
  AesGcmCookieEncryptor,
  FileCookieStore,
  createAgrarmonitorClient,
} from 'agrarmonitor-connector';

const agrarmonitor = await createAgrarmonitorClient({
  baseUrl: 'https://admin7.agrarmonitor.de',
  apiToken: process.env.AGRARMONITOR_API_TOKEN,
  username: process.env.AGRARMONITOR_USERNAME ?? '',
  password: process.env.AGRARMONITOR_PASSWORD ?? '',
  cookieStore: new FileCookieStore(
    process.env.AGRARMONITOR_COOKIE_PATH ?? './data/agrarmonitor-cookies.json',
    {
      encryptor: process.env.AGRARMONITOR_ENCRYPTION_KEY
        ? new AesGcmCookieEncryptor(process.env.AGRARMONITOR_ENCRYPTION_KEY)
        : undefined,
      logger: console,
    }
  ),
  logger: console,
});

const freischaltung = await agrarmonitor.checkFreigeschaltet();
console.log(freischaltung.freigeschaltet);

const registrierung = await agrarmonitor.checkRegistriert();
console.log(registrierung.registriert);

const response = await agrarmonitor.http.get('/kunden/detail/123');
console.log(response.status);

Cookie Persistence

FileCookieStore keeps one shared CookieJar per file path inside the Node process. Multiple connector instances that use the same cookie file therefore reuse the same session and every successful request saves the latest cookies back to disk.

The store can read both the connector format and the older Telefonbuch cookie-array format.

Useful Methods

• checkFreigeschaltet() checks whether Agrarmonitor redirects to /freischaltung/.
• checkRegistriert() checks whether the page still contains Neues Gerät registrieren.
• registerDevice({ agrarmonitorId, pcName }) loads /freischaltung/, extracts the nonce, and posts the registration request.
• fetchCustomers() loads customers from https://api.agrarmonitor.de/v1/kunden.
• saveSession() explicitly persists the current cookie jar.
