Since the used deferred load library is no longer maintained it is removed and replaced with similar standard browser functionality
All uses of the
(deferLoad) directive in custom code need to be replaced.
The PWA 2.4 contains an Angular update to version 13.3.10 and many other dependencies updates.
These updates did not require any updates to the PWA source code.
But it needs to be checked if this is true for your projects customizations as well.
We introduced a checkout guard that protects the checkout routes in case no shopping cart is available and navigates back to the empty basket page.
Routes to non-existing CMS content pages now result in a "Page Not Found" error page.
The 'ratings' functionality (components concerning the display of product ratings) has been moved into an extension using the existing feature toggle 'ratings'.
With the display of product reviews the attribute 'numberOfReviews' has been added to the product model and the number of reviews is now displayed behind the product rating stars instead of the average rating that is already depicted in the stars.
The 'contact us' functionality has been moved into an extension and we have introduced the feature toggle
contactUs in the
environment.model.ts that is switched on by default.
getFilteredProducts method has been moved from the
FilterService to the
ProductsService, since the
/products API is used.
Together with this change the default products attributes for product listings are externalized and and are now easily overridable.
With #1135, the default model representation used by
NgbDatepicker is now the native ES6
During this refactoring, the
DateHelper class has been removed. This will not concern you if you use
However, if you use
NgbDatepicker outside of formly, some helpers you might have used are gone.
Please use the underlying functions from
date-fns directly or create your own
The PWA 2.2 contains an Angular update to version 13.3.0 and many other dependencies updates.
These updates required some internal webpack handling changes especially for the template overloading.
Also some test adaptions where necessary, so is it now necessary to mock the
Another change is the Formly downgrade from v6 pre-release to v5 that still works with Angular 13 with a changed
After the updates the deprecated RxJS MapTo operators (
switchMapTo) were replaced Deprecating MapTo variants.
Linting will point out these issues in custom code that can than easily be replaced.
The Intershop PWA now uses Node.js 16 LTS with a corresponding npm version >=8.0.0.
With this new npm, calls using
npx npm-run-all in CI have to be changed to
npm run exec npm-run-all.
Changes with Angular 13 require to declare less dependencies in test beds than before.
For that reason the PWA 2.2 contains two pull requests that cleanup a lot of test specs (see #1057 and #1072).
It is not considered a breaking change but it might result in merge conflicts with customized Jest tests.
To cleanup the own code base run
npm run cleanup-testbed.
npm run cleanup-testbed -- --help for more detailed options.
shared/formly folder - containing all custom types, wrappers, etc. - was updated.
For a cleaner separation of code artifacts, there are now multiple subfolders declaring their own modules where formly is partly configured.
FormlyModule brings all these together so you can use it just like before.
If you made any changes in
shared/formly, you will have to adapt the corresponding modules.
Additionally, we introduced a
formly/field-library subfolder that contains a
FieldLibrary service which enables you to define reusable
FormlyFieldConfigs and access them easily.
If you have customized anything in
shared/formly-address-forms/configurations/address-form-configuration.ts, for example the
standardFields variable, you will have to migrate these changes by defining new
The address form configurations now use the new
FieldLibrary functionality under the hood.
For more information, read the new Field Library documentation.
The compare products functionality was moved into an extension.
The already existing
compare feature toggle works as before but the compare components integration changed to lazy components, e.g.
<ish-product-add-to-compare displayType="icon"></ish-product-add-to-compare> to
For other compare components check the compare-exports.module.ts file.
The recently viewed products functionality was moved into an extension.
The already existing
recently feature toggle works as before but the recently viewed component integration changed from
<ish-recently-viewed *ishFeature="'recently'"></ish-recently-viewed> to
This was already changed for the product detail page and the basket page but needs to be done for any customized usage of the recently viewed component.
clean-localizations functionality was changed so that
keep-localization-pattern can be defined where they are used and do no longer need to be added directly to the
It might be useful to move custom patterns according to the changes done for the standard code (for more information see Localization File Clean Up Process).
TestBed configuration arrays are sorted again as of 2.1 This means a lot of (small, auto-fixable) changes across the codebase.
ng lint --fix in order to sort your arrays.
If you have a lot of migration changes, you might be required to run it more than once.
With the introduction of personalized REST calls for categories and products, data in the ngrx store runs the risk of not being up-to-date after a login or logout.
To fix this, a new
resetSubStatesOnActionsMeta meta-reducer was introduced to remove potentially invalid data from the store.
If the removal of previous data from the store is not wanted this meta reducer should not be used in customized projects.
In addition a mechanism was introduced to trigger such personalized REST calls after loading the PGID if necessary.
This way of loading personalized data might need to be added to any custom implementations that potentially fetch personalized data.
To get an idea of the necessary mechanism search for the usage of
personalizationStatusDetermined in the source code.
Since TSLint has been deprecated for a while now and Angular removed the TSLint support we had to migrate our project from TSLint to ESLint as well.
This means in version 2.0 all TSLint rules and configurations were removed and where possible replaced by ESLint.
This not only required configuration changes in the Intershop PWA project but also application code adaptions to comply with some of the new ESLint rules.
To allow for an as easy as possible migration of existing PWA projects, we split the whole switch in separate commits that should make it easier to resolve potential merge conflicts by providing some context, e.g. changes to satisfy a specific rule or project configuration changes etc.
We advise you to first cherry pick all the
eslint commits provided by the PWA release before applying the lint rules to the project customizations to fix the issues that reside in the project code.
If the found issues are too many to address them in an ordered manner, it is probably best to temporarily disable some of the failing rules in
.eslintrc.json (see Configuring ESLint and to only fix one after another.
It is also probably a good idea to do the PWA 2.0 migration not in one go as described in Import Changes from New PWA Release but to first do the commits before the linter switch and bring your project to a clean state (
npm run check).
After this all the linter switch commits should be applied and the project should be brought back to a clean state.
Once this is done, subsequent commits should be migrated.
If your project contains own custom TSLint rules you will have to re-implement them as ESLint rules to be able to apply them to your code base (see Custom ESLint rules).
With version 2.0 we introduce a renaming of the two standard PWA themes and change the default theme:
blueis now called
b2band is used as default theme from now on.
defaultis now called
With this change the according folders and references had to be renamed/moved and need to be adapted in customer projects as well.
In projects where the recommended procedure for using a custom theme has been followed (see Customization Guide - Start Customization), minimal migration effort should be required.
We moved the model
SelectOption from the select.component.ts to the
select-option.model.ts and adapted all necessary imports.
In the PWA 0.28 we introduced the usage of Formly to generate and maintain our forms.
Now we removed the obsolete form components.
If you want to use the obsolete form components in your project nevertheless, skip the commit
remove obsolete form components.
For more information concerning Formly please refer to our Formly - Guide).
The feature toggle 'advancedVariationHandling' has been removed.
Instead the ICM channel preference 'AdvancedVariationHandling' is used to configure it.
You will find this preference as 'List View' in the ICM backoffice under Channel Preferences -> Product Variations.
The ICM channel preference 'basket.maxItemQuantity' is included to validate the product quantity if no specific setting is defined on the product.
You find this preference as 'Maximum Quantity per Product in Cart' under the Application Settings -> Shopping Cart & Checkout.
The default value is 100.
The Intershop PWA 2.0 release includes the Angular 13 update and updates to a lot of other dependencies (NgRx, RxJS, Formly, Swiper).
These dependencies updates require many necessary code adaptions that are included in additional commits.
The following official guides might help to migrate custom code as well:
To help with the necessary rxjs refactorings, consider using rxjs-fixers-morph.
npx rxjs-fixers-morph ./tsconfig.json.
dist folder now only contains results of the build process (except for
You must not edit any file inside that
dist folder, since this would include not being able to change Kubernetes liveness or readiness probes we included SSR container related source code under
The Angular configuration mechanism of the Intershop PWA was refactored to support running multiple configurations in one docker image (see Guide - Multiple Themes).
This now means that the former
environment.local.ts which had a standalone configuration can no longer be supported.
Instead theme-specific environments exist for
blue and development settings can be overridden in
environment.development.ts, which are imported into the theme-specific configurations (see Guide - Development).
npm install will create an initial version of the
environment.development.ts that can be filled with the needed information from
environment.local.ts itself becomes obsolete and can be deleted.
Locale definitions in
environment.ts models are no longer supported, only ICM channel configurations are now used for switching locales.
We introduced the feature toggle 'guestCheckout' in the
We switched to encode user logins when used in the api service.
This is to enable special characters (like the #) that are sometimes present in user logins (SSO case!) but would've lead to errors before.
We removed the property
production from Angular CLI
Production mode can now consistently be set by using Angular CLI configurations.
This also works when running multiple configurations like
We removed the property
serviceWorker from Angular CLI
The Service Worker can now be set consistently depending on the current configuration in the
We introduced formly to handle all kinds of forms from now on.
src/app/shared/address-forms in favor of
src/app/shared/forms-dynamic in favor of a generalized formly integration in
To implement your country-specific address forms in formly, see Forms.
We introduced an improved usage of memoized selectors for products selectors, split up state and saved additionally retrieved data in separate places and migrated almost all product related components to use the previously introduced product context facade (see changes #528).
We upgraded Cypress from Version 4 to 6 and followed all migrations in their Migration Guide.
productinput, as they retrieve the product from the context.
The project configuration was updated to use and test with Node.js version 14.15.0 LTS (including npm 6.14.8) for any further development.
We upgraded the Intershop PWA to use Angular 11.
With that a breaking change was introduced.
relativeLinkResolution property changed from
We couldn't detect any impact for the PWA itself but custom code might have to be adapted.
We removed the Intershop PWA mock-data, as there are currently public servers provided for testing and exploring.
The handling for mocking REST API calls during development is hereby untouched.
The Angular CLI environment property
mockServerAPI became obsolete, the property
mustMockPaths was renamed to
We replaced the simple ngx-cookie-banner cookie banner with an own implementation that provides the means to configure and set more fine grained cookie consent options.
A basic configuration is already provided.
The cookie consent configuration and usage is documented in our Cookie Consent Guide.
With this change it is necessary to adapt all uses of the
cookiesService.cookieLawSeen$ observable with the new synchronous method -
cookiesService.cookieConsentFor('tracking') - provided to check for the required cookie consent.
We reworked the configuration format for setting up multiple channels in the nginx to enable context-path support.
PWA_X_ environment properties are no longer supported, instead a structured configuration has to be supplied.
For more information see Nginx documentation.
We introduced a localization file clean up script that removes all unused localization keys from the localization files and sorts the remaining keys.
The clean up result is contained in a separate commit that should probably not be applied during a migration and instead a
npm run clean-localizations should be performed on the project sources.
We renamed the testing helper
findAllCustomElements to support project customization.
The returned lists from
findAllDataTestingIDs are no longer sorted to represent the actual template structure.
With Angular version 10.1, the testing utility async was deprecated.
We refactored out code base to use native async/await instead, which was possible in all cases.
The TSLint rule
use-new-async-in-tests takes care of automatically transforming TestBed initialization code in component tests.
Other cases have to be refactored manually.
We removed deprecated exports related to the NgRx testing refactorings introduced in version 0.21.
We switched our main development to the new headless REST application type provided by ICM 22.214.171.124.
If you are upgrading and want to continue using the Responsive Starter Store application types, do not cherry-pick the commits that switch application types.
We refactored the way ICM Http Errors are handled in the PWA.
You can read about it here.
Tests emulating HTTP errors now have to use the helper function
We removed grouping folders of shared components in extensions and sub projects for a better overview.
You can migrate using the script
node schematics/migration/0.22-to-0.23 (for running this script Git version 2.28 or above is recommended since earlier versions resulted in problems).
We deprecated and reworked the way of testing with NgRx.
The old format using
combineReducers is now deprecated and replaced by the new approach.
The old testing mechanism will be removed in version 0.23.
We introduced a way to do shallow testing with feature toggles and used it in the tests.
TSLint rules are set up to automatically fix imports, so run
npm run check after upgrading.
In this version, we decided to start using the ngrx creator introduced in ngrx v8: createAction, createReducer and createEffect.
This means that the old way of writing action classes, reducer switch statements and @effect() decorators is deprecated from 0.21 onwards.
Using these creator functions simplifies code and removes a lot of boiler plate from store files while providing type safety out-of-the-box.
You can automatically migrate your existing code by executing
Doing this will set related ts-lint rules and update each store or notify you of work previously needed.
We upgraded from Angular 8 to version 9 and activated the new rendering engine Ivy with this (following the official upgrade guide).
This was a major upgrade and comes with some changes:
The following changes are available for cherry-picking in one commit:
Angular no longer supports the previously deprecated string syntax for lazy loaded modules. Change it to the dynamic import format.
server.ts was partially rewritten to support SSR dev-server and serverless deployments. Building SSR is now supported by Angular CLI and explicit
webpack builds were removed.
core-js had a major upgrade to version 3, so
polyfill.ts imports have changed.
We temporarily replaced
ngx-utils-cookies-port due to a bug when using Angular 9.1.
angular2-cookie-law was replaced by
ngx-cookie-banner for compatibility reasons. This comes with a styling overhaul.
Further commits contain necessary refactoring:
TestBed.get in tests was deprecated in favor of the new type-safe
The empty generic type for NgRx
Store is now the default and does not have to be supplied. The TSLint rule
ngrx-use-empty-store-type was adapted to apply this refactoring.
We removed lazy loading with
@wishtack/reactive-component-loader and replaced it with the native Angular 9 approach. If you have customized or created extensions, you will have to adapt the following:
Extension export modules are no longer imported and exported in
SharedModule, instead export them in
Instead of pointing to the extension module with
ReactiveComponentLoaderModule in the extension exports module, use the new provider for
LAZY_FEATURE_MODULE pointing to the extension store module, if available. All further lazy loading is done by lazy components and lazy loaded pages. With this, the extension module should no longer import the extension store module.
Lazy components should no longer be part of the repository as they can be auto-generated on
npm install. Use the new decorator
@GenerateLazyComponent() via the
lazy-component schematic to generate lazy components. We currently do not support creating lazy components for components with
@Output() decorated fields.
Previous workarounds in
<extension>-store.module.ts for adding reducers of selecting the feature state are no longer necessary and can be refactored to standard approaches.
We performed a major upgrade to
prettier which comes with new code formatting for parts of the code.
We replaced VSCode extension
stylelint-plus with the official extension. Update the recommended extensions.
We overhauled the integration of utility libraries for our custom schematics and TSLint rules. These libraries now get built when
We migrated from using ngrx-router to the official and better supported @ngrx/router-store.
This means that throughout the code all usage of the
ofRoute operator and
RouteNavigation actions are no longer available.
As some of these implementations were very specific, we cannot provide a migration script.
In this version change, we decided to no longer recommend the container-component-pattern and therefore changed the folder structure of the project.
We did this because the previously introduced facades provide a more convenient way to interact with the state management and more and more logic was moved out of containers, hence removing all ngrx-related imports there.
You can run the migration by executing
The script will check if all your components can be moved to the new folder structure and will then perform the migration or notify you of work previously needed.
