Breaking Changes

Removed ABP.Root.requirements

The deprecated ABP.Root.requirements property has been removed. Remove any references to this property in your code.

Deprecated ABP.FullRoute

ABP.FullRoute is now deprecated. Use the new RoutesService for route management instead.

Deprecated ConfigStateService.getRoute()

The getRoute() method on ConfigStateService is deprecated. Use RoutesService instead:

// Before (deprecated)
const route = configStateService.getRoute('/users');

// After (v3.0.0)
import { getRoutesService, findRoute } from '@abpjs/core';

const routesService = getRoutesService();
const route = findRoute(routesService, '/users');

New Features

RoutesService

A new service for tree-based route management, replacing the legacy ConfigState route handling:

import { getRoutesService, RoutesService } from '@abpjs/core';

const routesService = getRoutesService();

// Add routes
routesService.add([
  { name: 'Dashboard', path: '/dashboard', order: 1 },
  { name: 'Users', path: '/users', order: 2 },
  { name: 'UserDetails', path: '/users/:id', parentName: 'Users' },
]);

// Get flat list of routes
const allRoutes = routesService.flat;

// Get tree structure
const routeTree = routesService.tree;

// Get visible routes (filtered by permissions and invisible flag)
const visibleRoutes = routesService.visible;

// Find a route
const usersRoute = routesService.find((route) => route.name === 'Users');

// Search by partial properties
const route = routesService.search({ path: '/dashboard' });

// Patch a route
routesService.patch('Dashboard', { order: 10 });

// Remove routes
routesService.remove(['UserDetails']);

// Check for children
routesService.hasChildren('Users'); // true

// Subscribe to changes
const unsubscribe = routesService.subscribe(() => {
  console.log('Routes changed');
});

SettingTabsService

A new service for managing setting page tabs:

import { getSettingTabsService } from '@abpjs/core';

const settingTabsService = getSettingTabsService();

  { name: 'Notifications', order: 3 },
]);

// Get visible tabs
const visibleTabs = settingTabsService.visible;

AbstractTreeService and AbstractNavTreeService

// For generic tree structures
class MyTreeService extends AbstractTreeService<MyItem> {
  readonly id = 'id';
  readonly parentId = 'parentId';
  readonly hide = (item) => item.hidden;
  readonly sort = (a, b) => a.order - b.order;
}

// For navigation items (routes, tabs, menus)
class MyNavService extends AbstractNavTreeService<ABP.Nav> {
  // Inherits id='name', parentId='parentName'
  // Inherits permission-based filtering
}

Tree Utilities

New utilities for working with tree structures:

import {
  TreeNode,
  BaseTreeNode,
  createTreeFromList,
  createMapFromList,
  findInTree,
  flattenTree,
  sortTree,
} from '@abpjs/core';

// TreeNode type

  parent?: TreeNode<T>;
};

// Create tree from flat list
const items = [
  { id: '1', parentId: null, name: 'Root' },
  { id: '2', parentId: '1', name: 'Child' },
];

const tree = createTreeFromList(
  items,
  (item) => item.id,        // keySelector
  (item) => item.parentId,  // parentKeySelector
  (item) => item            // valueMapper

Array Utilities

New utilities for array manipulation:

import { pushValueTo, uniqueBy, groupBy } from '@abpjs/core';

// pushValueTo - functional composition helper
const items: string[] = [];
const addItem = pushValueTo(items);
addItem('first');  // returns ['first']
addItem('second'); // returns ['first', 'second']

// uniqueBy - remove duplicates
const users = [
  { id: 1, name: 'John' },
  { id: 2, name: 'Jane' },
  { id: 1, name: 'John Doe' },
];
const unique = uniqueBy(users, (user) => user.id);
// [{ id: 1, name: 'John' }, { id: 2, name: 'Jane' }]

// Simple deduplication
const numbers = [1, 2, 2, 3, 3, 3];
const uniqueNumbers = uniqueBy(numbers);

// Default ABP.PageQueryParams
const listService = new ListService();

// Custom query params type
interface MyQueryParams {
  filter?: string;
  maxResultCount: number;
  skipCount: number;
  sorting?: string;
  category?: string;
  status?: number;
}

const customListService = new ListService<MyQueryParams>();

// Type-safe query access

import { useAbp } from '@abpjs/core';

function MyComponent() {
  const { localizationService } = useAbp();

  // Localize by resource name and key
  const text = localizationService.localizeSync('AbpIdentity', 'Users', 'Users');

  // Async version
  const asyncText = await localizationService.localize('AbpIdentity', 'Users', 'Users');

  // With fallback across multiple resources/keys
  const fallbackText = localizationService.localizeWithFallbackSync(
    ['MyModule', 'AbpIdentity'],
    ['UserManagement', 'Users'],
    'Users'
  );
}

LazyLoadService.remove()

New method to remove dynamically loaded resources:

import { LazyLoadService, LOADING_STRATEGY } from '@abpjs/core';

const lazyLoadService = new LazyLoadService();

// Load a script
await lazyLoadService.load(
  LOADING_STRATEGY.AppendAnonymousScriptToHead('https://cdn.example.com/lib.js')
);

// Later, remove it from the DOM
const removed = lazyLoadService.remove('https://cdn.example.com/lib.js');
console.log(removed); // true if found and removed

API Changes

• ApplicationConfiguration.CurrentUser.email - New field for user's email address
• ABP.Root.sendNullsAsQueryParam - Option to include null values in query strings
• LazyLoadService.loaded - Changed from Set<unknown> to Map<string, HTMLElement> for element tracking
• LoadingStrategy.element - New property containing the created element reference after loading

Breaking Changes

• LazyLoadService.loaded type changed - If you were accessing this property directly, note it's now a Map instead of Set:

  // Before (v2.4.0 - v2.7.0)
  lazyLoadService.loaded.has(path); // Set method
  
  // After (v2.9.0) - still works, Map also has .has()
  lazyLoadService.loaded.has(path); // Map method
  
  // New: get the element
  const element = lazyLoadService.loaded.get(path);

// AuditedEntityDto - adds lastModificationTime, lastModifierId
// FullAuditedEntityDto - adds isDeleted, deleterId, deletionTime

// With user references:
import {
  CreationAuditedEntityWithUserDto,
  AuditedEntityWithUserDto,
  FullAuditedEntityWithUserDto,
} from '@abpjs/core';

Loading Strategies

New strategy-based approach for loading external scripts and styles:

import {
  LazyLoadService,
  LOADING_STRATEGY,
  DOM_STRATEGY,
  CROSS_ORIGIN_STRATEGY,
} from '@abpjs/core';

const lazyLoadService = new LazyLoadService();

// Load script using pre-configured strategy
await lazyLoadService.load(
  LOADING_STRATEGY.AppendAnonymousScriptToHead(
    'https://cdn.example.com/library.js',
    'sha384-...' // optional integrity hash
  )
);

// Load stylesheet
await lazyLoadService.load(
  LOADING_STRATEGY.AppendAnonymousStyleToHead(
    'https://cdn.example.com/styles.css'
  )
);

// Check if already loaded
if (!lazyLoadService.isLoaded('https://cdn.example.com/library.js')) {
  await lazyLoadService.load(/* ... */);
}

Available LOADING_STRATEGY presets:

• AppendAnonymousScriptToBody(src, integrity?)
• AppendAnonymousScriptToHead(src, integrity?)
• AppendAnonymousStyleToHead(src, integrity?)
• PrependAnonymousScriptToHead(src, integrity?)
• PrependAnonymousStyleToHead(src, integrity?)

Content Strategies

For inserting inline scripts and styles:

import {
  DomInsertionService,
  getDomInsertionService,
  CONTENT_STRATEGY,
} from '@abpjs/core';

const domInsertionService = getDomInsertionService();

// Insert inline style
domInsertionService.insertContent(
  CONTENT_STRATEGY.AppendStyleToHead(`
    .my-class { color: red; }
  `)
);

// Insert inline script
domInsertionService.insertContent(
  CONTENT_STRATEGY.AppendScriptToHead(`
    console.log('Script loaded');
  `)
);

// Check if content was already inserted
if (!domInsertionService.hasInserted(myContent)) {
  domInsertionService.insertContent(/* ... */);
}

Available CONTENT_STRATEGY presets:

• AppendScriptToBody(content)
• AppendScriptToHead(content)
• AppendStyleToHead(content)
• PrependStyleToHead(content)

DOM Strategies

Low-level control over element insertion:

import { DOM_STRATEGY, DomStrategy } from '@abpjs/core';

// Pre-configured strategies
DOM_STRATEGY.AppendToHead()    // Insert at end of <head>
DOM_STRATEGY.PrependToHead()   // Insert at start of <head>
DOM_STRATEGY.AppendToBody()    // Insert at end of <body>
DOM_STRATEGY.BeforeElement(el) // Insert before element
DOM_STRATEGY.AfterElement(el)  // Insert after element

// Custom strategy
const strategy = new DomStrategy(
  document.getElementById('container')!,
  'beforeend'
);

Cross-Origin Strategies

Configure CORS and integrity for loaded resources:

import { CROSS_ORIGIN_STRATEGY } from '@abpjs/core';

// Anonymous CORS with SRI integrity
CROSS_ORIGIN_STRATEGY.Anonymous('sha384-...');

// Credentials CORS
CROSS_ORIGIN_STRATEGY.UseCredentials();

Content Security Strategies

Apply CSP nonces to dynamically inserted content:

import { CONTENT_SECURITY_STRATEGY } from '@abpjs/core';

// Apply nonce for CSP compliance
CONTENT_SECURITY_STRATEGY.Loose('nonce-abc123');

// No CSP (default)
CONTENT_SECURITY_STRATEGY.None();

API Changes

• Config.Environment.hmr - New optional boolean flag for Hot Module Replacement
• Config.ApiConfig - New interface type for API configuration (previously inline)
• Rest.Config.apiName - Specify which API to use for requests (from Config.Apis)

New Utilities

import {
  isUndefinedOrEmptyString,
  generateHash,
  fromLazyLoad,
  noop,
} from '@abpjs/core';

// Check for undefined or empty string
isUndefinedOrEmptyString(undefined); // true
isUndefinedOrEmptyString('');        // true
isUndefinedOrEmptyString('hello');   // false

// Generate hash from string
const hash = generateHash('my-string'); // number

// Load element with promise
const script = document.createElement('script');
script.src = 'https://example.com/lib.js';
await fromLazyLoad(script, DOM_STRATEGY.AppendToHead());

// No-op function
const doNothing = noop();

Deprecations

• ABP.Root.requirements - Deprecated and now optional. Removed in v3.0.0.

v2.2.0

February 2026

• Version alignment with @abp/ng.core

---

v2.1.0

February 2026

New Features

• ConfigStateService.dispatchSetEnvironment() - New dispatch method to set the environment configuration at runtime:

  function MyComponent() {
    const { configStateService } = useAbp();
  
    // Update environment configuration
    configStateService.dispatchSetEnvironment({
      production: true,
      application: { name: 'My App' },

      apis: { default: { url: 'https://api.example.com' } },
    });
  }

API Changes

• toLocalISOString made optional - The Date.prototype.toLocalISOString method is now optional to match the Angular API. Use optional chaining when calling:

  // Before (v2.0.0)
  const isoString = date.toLocalISOString();
  
  // After (v2.1.0) - use optional chaining for safety
  const isoString = date.toLocalISOString?.();

New Services

• ConfigStateService - Renamed from ConfigService to align with Angular ABP naming conventions:

  import { ConfigStateService } from '@abpjs/core';
  
  // Access via useAbp hook
  const { configStateService } = useAbp();
  
  // Get application info
  const appInfo = configStateService.getApplicationInfo();
  
  // Find route by path, name, or url
  const route = configStateService.getRoute('/users', undefined, undefined);
  const routeByName = configStateService.getRoute(undefined, 'Users');
  const routeByUrl = configStateService.getRoute(undefined, undefined, '/admin/users');
  
  // Get settings with optional keyword filter
  const emailSettings = configStateService.getSettings('Email');
  
  // Get localized string with interpolation
  const greeting = configStateService.getLocalization(
    { key: 'HelloUser', defaultValue: 'Hello!' },
    'John'
  );

• SessionStateService - Access session state (language, tenant):

  import { SessionStateService } from '@abpjs/core';
  
  const { sessionStateService } = useAbp();
  
  const language = sessionStateService.getLanguage();
  const tenant = sessionStateService.getTenant();

• ProfileStateService - Access profile state:

  import { ProfileStateService } from '@abpjs/core';
  
  const { profileStateService } = useAbp();
  
  const profile = profileStateService.getProfile();

LocalizationService Enhancements

The LocalizationService methods now accept Config.LocalizationWithDefault in addition to string keys:

// String key (existing)
const text = localizationService.get('MyKey');

// Object with default value (new)
const textWithDefault = localizationService.get({
  key: 'MyKey',
  defaultValue: 'Fallback text'
});

// With interpolation
const greeting = localizationService.get('Hello {0}!', 'World');

Affected methods: get(), instant(), t()

New Date Extension

Date.prototype.toLocalISOString() - Returns ISO string in local timezone (unlike toISOString() which returns UTC):

const date = new Date();

// Standard - returns UTC
date.toISOString();      // "2026-01-31T13:15:00.000Z"

// New - returns local timezone
date.toLocalISOString(); // "2026-01-31T16:15:00.000+03:00"

New Types

• Config.LocalizationParam - Union type for localization keys:

  type LocalizationParam = string | LocalizationWithDefault;
