Importing business process models from BPMN DI files to ADONIS

The NodeJS snippet in this article shows how to first iterate through a set of bpmn files in the project's assets folder and then for each one uses the ADONIS Import BPMN DI API to import the file's content as BPMN model to ADONIS.


The NodeJS snippet below uses Basic Authentication.

Replace the values in angle brackets with values that fit your setup, e.g. instead of <USERNAME> use the name of the user that should be used to access the REST API.

const axios = require("axios");
const fs = require("fs").promises;
const path = require("path");

const USERNAME = "<USERNAME>"; // Replace <USERNAME> with your username.
const PASSWORD = "<PASSWORD>"; // Replace <PASSWORD> with your password.
const REPO_ID = "<REPO_ID>"; // Replace <REPO_ID> with your repository's id. (e.g. {16bcc961-f38b-482a-b056-8691f93e4eb8} note that {} are optional.)
const GROUP_ID = "<GROUP_ID>"; // Replace <GROUP_ID> with the id of the group you want to import into. (e.g. {ee4729e0-67ef-41e6-96ec-89844f93bea2} note that {} are optional.)
const REST_BASE_URL = "<REST_BASE_URL>"; // Replace <REST_BASE_URL> with the path to your web client (e.g. http://server:port/ADOweb).
const FOLDER_PATH = "<FOLDER_PATH>"; // Replace <FOLDER_PATH> with the path to the folder of your .bpmn files. (e.g. assets\\bpmn)
const API_VERSION = "2.1"; // Replace <API_VERSION> if needed, default is 2.1

const restUrl = `${REST_BASE_URL}/rest/${API_VERSION}/repos/${REPO_ID}/modelgroups/${GROUP_ID}/actions?type=import`;
const base64Credentials = Buffer.from(`${USERNAME}:${PASSWORD}`).toString("base64");
