Adapter-Core

Core module to be used in ioBroker adapters. Acts as the bridge to js-controller.

This replaces the utils.js included in the ioBroker template adapter.

Usage

  1. Add this as a dependency: npm i @iobroker/adapter-core
  2. Replace
    const utils = require(__dirname + '/lib/utils');
    with
    const utils = require('@iobroker/adapter-core');
  3. Create an adapter instance as usual:
    // old style
    const adapter = utils.adapter(/* options */);
    // new style (classes). See https://github.com/ioBroker/ioBroker.template/ for a more detailed usage
    class MyAdapter extends utils.Adapter {...}

Utility methods

Compared to the old utils.js, some utility methods were added.

getAbsoluteDefaultDataDir

const dataDir = utils.getAbsoluteDefaultDataDir();

This returns the absolute path of the data directory for the current host. On linux, this is usually /opt/iobroker/iobroker-data

getAbsoluteInstanceDataDir

// old style
const instanceDataDir = utils.getAbsoluteInstanceDataDir(adapter);
// new style (classes)
const instanceDataDir = utils.getAbsoluteInstanceDataDir(this);

Returns the absolute path of the data directory for the current adapter instance. On linux, this is usually /opt/iobroker/iobroker-data/<adapterName>.<instanceNr>

EXIT_CODES

adapter.terminate('for some reason', utils.EXIT_CODES.ADAPTER_REQUESTED_TERMINATION);

Use standardized exit codes if your adapter needs to terminate.

commonTools

A collection of various utility methods and modules from JS-Controller. Prefer this over trying to find lib/tools.js and similar internal modules from the controller yourself!

Currently, the following methods are available:

  • commonTools.pattern2RegEx - Converts a pattern to match object IDs into a RegEx string that can be used in new RegExp(...)
  • commonTools.getAdapterDir - Finds the adapter directory of a given adapter
  • commonTools.getInstalledInfo - Get a list of all installed adapters and controller version on this host
  • commonTools.getLocalAddress - Get the localhost (IPv6 or IPv4) address according to the ioBroker config
  • commonTools.getListenAllAddress - Get the "listen all" (IPv6 or IPv4) address according to the ioBroker config
  • commonTools.isLocalAddress - Check if given IPv4 or IPv6 ip address corresponds to localhost
  • commonTools.isListenAllAddress - Check if given IPv4 or IPv6 ip address corresponds to "listen all" address
  • commonTools.ensureDNSOrder - Ensure that DNS resolution is performed according to ioBroker config

And the following modules are exposed:

  • commonTools.password - Previously exposed as lib/password.js in JS-Controller.
  • commonTools.session - Previously exposed as lib/session.js in JS-Controller.
  • commonTools.zipFiles - Previously exposed as lib/zipFiles.js in JS-Controller.
  • commonTools.isDocker - Checks if we are running inside a docker container

Note that commonTools.letsEncrypt is not available anymore as the next controller won't support it (use @iobroker/webserver instead).

I18n

Developer can use internationalisation in backend.

For that call

const I18n = require('@iobroker/adapter-core').I18n;

// later in "ready" method
await I18n.init(__dirname, adapter);
// If you use class syntax, you can use `this` instead of `adapter`
await I18n.init(__dirname, this);
// You can provide the language directly
await I18n.init(__dirname, 'de');

and then in code

console.log(I18n.translate('text to translate %s', 'argument1'));
// or to get the ioBroker.Translated object
console.log(JSON.stringify(I18n.getTranslatedObject('text to translate %s and %s', 'argument1', 'argument2')));

You can place your i18n folder in root of adapter or in lib folder. If your i18n files are in lib directory, so call the init function like this:

const { join } = require('node:path');
const I18n = require('@iobroker/adapter-core').I18n;

await I18n.init(join(__dirname, 'lib'), adapter);

Expected structure of i18n directory

+ i18n
  - de.json
  - en.json
  - es.json
  - fr.json
  - it.json
  - nl.json
  - pl.json
  - pt.json
  - ru.json
  - uk.json
  - zh-cn.json

And an example of i18n files could be found here

Automatic backup of data files

ioBroker has the ability to include files written by adapters in its backups. To enable that, you need to add the following to io-package.json:

{
    // ...
    "common": {
        // ...
        "dataFolder": "path/where/your/files/are"
    }
}

This path is relative to the path returned by getAbsoluteDefaultDataDir(). The placeholder %INSTANCE% is automatically replaced by the instance number of each adapter, for example "dataFolder": "my-adapter.%INSTANCE%".

Tips while working on this module

  • npm run build creates a clean rebuild of the module. This is done automatically before every build;
  • npm run lint checks for linting errors;
  • npm run watch creates an initial build and then incrementally compiles the changes while working.
