Guide - Intershop Progressive Web App - Getting Started

Getting Started

Before working with this project, download and install Node.js with the included npm package manager.
Currently Node.js 12.x LTS with the corresponding npm is required.

This project was generated with Angular CLI and follows the Angular CLI style guide and naming conventions.


Quick Start

After having cloned the project from the Git repository, open a command line in the project folder and run npm install.

The project uses Angular CLI which has to be installed globally.
Run npm install -g @angular/cli once to globally install Angular CLI on your development machine.
Use ng serve --open to start up the development server and open the Progressive Web App in your browser.

The project can alternatively be run in production mode with npm start.

Customization

Before customizing the PWA for your specific needs, have a look at our Customization Guide and also have a look at the current PWA Guide first.

Development Server

Run ng serve or ng s for a development server that is configured by default via environment.ts to use mocked responses instead of actual REST calls.

Running ng serve --configuration production or ng s -c production starts a server that will communicate by default with the Intershop Commerce Management of our public demo via REST API (see the used environment.prod.ts for the configuration).

The project is also configured to support the usage of an own local environment file environment.local.ts that can be configured according to the development environment, e.g. with a different icmBaseURL or different configuration options (see the environment.model.ts).
This file will be ignored by Git so the developer-specific setting will not be committed.
To use this local environment configuration, the server should be started with ng s -c local.

Once the server is running, navigate to http://localhost:4200/ in your browser to see the application.
The application will automatically reload if you change any of the source files.

Running ng serve --port 4300 will start the server on a different port than the default 4200 port, e.g., if one wants to run multiple instances in parallel for comparison.

Running ng serve --open will automatically open a new browser tab with the started application.
The different start options can be combined.

Warning: Do not use webpack-dev-server in production!

Also have a look at further information in the Development Guide

Deployment

Deployments are generated to the dist folder of the project.

Use npm run build to generate the preferred Angular Universal enabled version.
On the server the dist/server.js script has to be executed with node.

Alternatively, you can use ng build --prod to get an application using browser rendering.
All the files under dist/browser have to be served statically.
The server has to be configured for fallback routing,
see Server Configuration in Angular Docs.

For a production setup we recommend building the docker image supplied with the Dockerfile in the root folder of the project.
Build it with docker build -t my_pwa ..
To run the PWA with multiple channels and Google PageSpeed optimizations, you can use the nginx docker image supplied in the sub folder nginx.

We provide templates for Kubernetes Deployments and DevOps for Microsoft Azure.

Progressive Web App (PWA)

To run the project as a Progressive Web App with an enabled Service Worker, use npm run start to build and serve the application.
After that open http://localhost:4200 in your browser and test it or run a PWA audit.
Currently only localhost or 127.0.0.1 will work with the service worker since it requires https communication on any other domain.

Running Tests

Run npm test to start an on the fly test running environment to execute the unit tests via Jest once.
To run Jest in watch mode with interactive interface, run npm run test:watch.

Run npm run e2e to execute the end-to-end tests via cypress.
You have to start your development or production server first as cypress will instruct you.

Head over to the Testing Concept documentation for more information.

Code Style

Use npm run lint to run a static code analysis.

For development make sure the used IDE or editor follows the EditorConfig configuration of the project and uses Prettier to help maintain consistent coding styles (see .editorconfig and .prettierrc.json).

Use npm run format to perform a formatting run on the code base with Prettier.

Pre-Commit Check

npm run check is a combination task of lint, format and test that runs some of the checks that will also be performed in continuous integration on the whole code base.
Do not overuse it as the run might take a long time.

Prefer using npx lint-staged to perform a manual quick evaluation of staged files.
This also happens automatically when committing files.
It is also possible to bypass verification on commit, following the suggestions of the versioning control tool of your choice.

Code Scaffolding

With the integrated intershop-schematics this project provides the functionality to generate different code artifacts according to our style guide and project structure. ng generate will use our custom schematics by default, e.g. run ng generate component component-name in the shared folder to generate a new shared component. ng generate --help gives an overview of available Intershop-specific schematics.

The Angular CLI default schematics are still available and working.
However, they need to be prefixed to use them, e.g. ng generate @schematics/angular:guard.
A list of the available Angular CLI schematics can be fetched with ng generate @schematics/angular: --help.

Further Help

To get more help on the Angular CLI, use ng help or check out the Angular CLI Documentation.
