Configuration

Environment Variables

Create a .env file in your project root with the following variables:

# BPA API variables
BPA_API_URL=https://bpa.your-domain.com
TOKEN=your-access-token-here
SERVICE_ID=your-service-id

# GDB API variables (if using GDB functions)
GDB_API_URL=https://gdb.your-domain.com
GDB_TOKEN=your-gdb-access-token

See .env.example for a template.

Usage

This package uses CommonJS module system, so you can require it in your Node.js application:

Importing the Library

CommonJS

// CommonJS require - All functions
const eregistrations = require('eregistrations-js');

// Or import specific functions
const { 
  // BPA API functions
  getServiceDeterminants, 
  createDeterminant,
  addDeterminantToComponent,
  getServiceRegistrations, 
  getServiceFields, 
  getServiceNames, 
  getServiceBots, 
  getServiceRoles,
  getServiceForms,

  // GDB API functions
  createOrModifyDatabase,
  getDatabaseSchema,
  getList,

  // Types
  Config,
  GdbConfig
} = require('eregistrations-js');

TypeScript/ES Modules

// TypeScript import - All functions
import * as eregistrations from 'eregistrations-js';

// Or import specific functions
import { 
  // BPA API functions
  getServiceDeterminants, 
  createDeterminant,
  addDeterminantToComponent,
  getServiceRegistrations, 
  getServiceFields, 
  getServiceNames, 
  getServiceBots, 
  getServiceRoles, 
  getServiceForms,

  // GDB API functions
  createOrModifyDatabase,
  getDatabaseSchema,
  getList,

  // Types
  Config,
  GdbConfig
} from 'eregistrations-js';
import { config as loadEnv } from 'dotenv';

// Load environment variables
loadEnv();

Configuration

BPA API Configuration

const bpaConfig: Config = {
  baseApiUrl: process.env.BPA_API_URL!,
  token: process.env.TOKEN!, // Access token is required
  serviceId: process.env.SERVICE_ID
};

GDB API Configuration

const gdbConfig: GdbConfig = {
  baseApiUrl: process.env.GDB_API_URL!,
  token: process.env.GDB_TOKEN!, // Access token is required
  catalogName: 'MyDatabase',
  code: 'MDB',
  version: 1
  // Additional properties as needed
};

Authentication

Starting from version 2.0.0, this library no longer handles authentication internally. You must provide a valid access token directly in the config object for both BPA and GDB APIs. You are responsible for obtaining and refreshing the tokens as needed from your authentication provider.

BPA API

The Business Process Automation (BPA) API provides functionality for managing services, determinants, forms, and more.

BPA Examples

Getting Service Determinants

try {
  const config: Config = {
    baseApiUrl: process.env.BPA_API_URL!,
    token: process.env.TOKEN!,
    serviceId: process.env.SERVICE_ID!
  };

  const determinants = await getServiceDeterminants(config);
  console.log('Service determinants:', determinants);
} catch (error) {
  console.error('Error:', error);
}

Creating a Determinant

try {
  const config: Config = {
    baseApiUrl: process.env.BPA_API_URL!,
    token: process.env.TOKEN!,
    serviceId: process.env.SERVICE_ID!,
    determinantName: "MyTextDeterminant",
    targetFormFieldKey: "someField",
    operator: "EQUALS",
    value: "someValue",
    type: "text"
  };

  const newDeterminant = await createDeterminant(config);

  console.log('Created determinant:', newDeterminant);
} catch (error) {
  console.error('Error:', error);
}

Adding a Determinant to a Component

try {
  const config: Config = {
    baseApiUrl: process.env.BPA_API_URL!,

} catch (error) {
  console.error('Error:', error);
}

try {
  const config: Config = {
    baseApiUrl: process.env.BPA_API_URL!,
    token: process.env.TOKEN!,
    serviceId: process.env.SERVICE_ID!
  };

  const bots = await getServiceBots(config);
  console.log('Service bots:', bots);
} catch (error) {
  console.error('Error:', error);
}

    token: process.env.GDB_TOKEN!,
    code: 'MyDatabaseCode', // The database code to query
    query: 'query.Name=John' // The query parameter to filter results
  };

  const results = await getList(config);
  console.log('Query results:', results);
  
  // You can access individual records if the result is an array
