NPM

ds-wrapper for the Digitalstrom Server

A simple wrapper based on promises.

Manages authentication and session tokens

The module can manage the task of retrieving and authenticating the application token, aswell as retrieving and refreshing the session token.

Usage

Import the module

/* specify dss ip and loglevel as parameter */
const ds = require('ds-wrapper')('192.168.188.4', 0);

Retrieving the application token

There is a fully automated process available, that enables the token by logging in the User.

The Application Token must be stored, because it does not expire, once authenticated!

/* Authentication */
let app_token;
ds.initializeAuthentication('appName', 'username', 'password').then((token) => {
    console.log(token);
    /* store token somewhere */
}, (err) => {
    console.log(err);
});

The option to authenticate the token in the user interface is also available, although not recommended.

retrieveApplicationToken('appName').then((appToken) => {
    console.log(appToken);
}, (err) => {
    console.log(err);
});

Sending requests

To request an action that has to be authenticated by a session token (refer to the docs...) another function can be used.

/* Performing actions */
const path = '/json/apartment/getName';

ds.requestWithSessionFromDSS(path, {test: true}, token).then((body) => {
    console.log(body);
}, (err) => {
    console.log(err);
});

Functions

requestWithSessionFromDSS

Performs a request to the dss with automatic session management.

/**

 * @param {string} path path to request
 * @param {Object} query params to query
 * @param {string} app_token Application token, that is activated
 * @returns {Promise} Promise: resolve(body) | reject(error)
 */
requestWithSessionFromDSS(path, query, app_token)

retrieveApplicationToken

/**
 * Retrieves AppToken from dss.
 * @param {String} readableAppName Human readable app name
 * @returns {Promise} Promise: resolve(token) | reject(err)
 */
retrieveApplicationToken(readableAppName)

activateApplicationToken

/**
 * Activates application token with credentials
 * @param {string} username dss username
 * @param {string} password dss password
 * @param {string} app_token application token
 * @returns {Promise} Promise: resolve() | reject(err)
 */
activateApplicationToken(username, password, app_token)

initializeAuthentication

/**
 * Automatic authentication of application in the dss
 * @param {string} readableName - Name of the application
 * @param {string} username - dss username
 * @param {string} password - dss password
 * @returns {Promise} Promise: resolve(appToken) | reject(err)
