Guide - Intershop Progressive Web App - Migrations

Migrations

0.31 to 0.32

Locale definitions in environment.ts models are no longer supported, only ICM channel configurations are now used for switching locales.

0.29 to 0.30

We introduced the feature toggle 'guestCheckout' in the environment.model.ts.

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.

0.28 to 0.29

We activated TypeScript's noImplicitAny.
Please refer to the Type Safety part in the Getting Started Guide for motivations.

0.27 to 0.28

We removed the property production from Angular CLI environment.ts files.
Production mode can now consistently be set by using Angular CLI configurations.
This also works when running multiple configurations like --configuration=brand,production.

We removed the property serviceWorker from Angular CLI environment.ts files.
The Service Worker can now be set consistently depending on the current configuration in the angular.json file.

We removed the dependency to ngx-swiper-wrapper as it will no longer be supported and swiper itself now natively supports Angular (see changes #552).

We introduced formly to handle all kinds of forms from now on.
We removed src/app/shared/address-forms in favor of src/app/shared/formly-address-forms and src/app/shared/forms-dynamic in favor of a generalized formly integration in src/app/shared/formly.
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).

0.26 to 0.27

We upgraded Cypress from Version 4 to 6 and followed all migrations in their Migration Guide.

We have introduced a Context Facade for product entities and refactored most of the components that are specific to a single product.
This includes:

  • Targeted components no longer require a product input, as they retrieve the product from the context.
  • The handling for adding products to the basket was refactored and simplified.
  • Product quantity handling moved almost completely to the context.
  • The decision for displaying certain components on product tiles and rows also moved into the context.

0.25 to 0.26

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.
The RouterModule's relativeLinkResolution property changed from legacy to corrected.
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 apiMockPaths.

0.24 to 0.25

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.
Multiple PWA_X_ environment properties are no longer supported, instead a structured configuration has to be supplied.
For more information see Nginx documentation.

0.23 to 0.24

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 findAllIshElements from ish-core/utils/dev/html-query-utils to findAllCustomElements to support project customization.
The returned lists from findAllCustomElements and 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.

0.22 to 0.23

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 7.10.21.0.
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 makeHttpError from ish-core/utils/dev/api-service-utils.

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).

0.20 to 0.21

We deprecated and reworked the way of testing with NgRx.
The old format using ngrxTesting with 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.

We reorganized the core store:

  • new customer
    • store/addresses => store/customer/addresses
    • store/checkout/basket => store/customer/basket
    • store/orders => store/customer/orders
    • store/restore => store/customer/restore
    • store/user => store/customer/user
  • new core
    • store/configuration => store/core/configuration
    • store/error => store/core/error
    • store/messages => store/core/messages
    • store/router => store/core/router
    • store/viewconf => store/core/viewconf
  • new general
    • store/contact => store/general/contact
    • store/countries => store/general/countries
    • store/regions => store/general/regions

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 node schematics/migration/0.20-to-0.21.
Doing this will set related ts-lint rules and update each store or notify you of work previously needed.

0.19.1 to 0.20

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 with 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 TestBed.inject.

    • 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 ShellModule.

      • 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.ts and <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 npm installing the PWA and transpiled JavaScript sources are no longer part of version control. Also, they mainly reuse libraries from the project root now.

0.18 to 0.19

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.

0.16 to 0.17

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 node schematics/migration/0.16-to-0.17.

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.
