You can also use `ng generate directive|pipe|service|class|guard|interface|enum|module`. 12 | 13 | ## Build 14 | 15 | Run `ng build` to build the project. The build artifacts will be stored in the `dist/` directory. 16 | 17 | ## Running unit tests 18 | 19 | Run `ng test` to execute the unit tests via [Karma](https://karma-runner.github.io). 20 | 21 | ## Running end-to-end tests 22 | 23 | Run `ng e2e` to execute the end-to-end tests via a platform of your choice. To use this command, you need to first add a package that implements end-to-end testing capabilities. 24 | 25 | ## Further help 26 | 27 | To get more help on the Angular CLI use `ng help` or go check out the [Angular CLI Overview and Command Reference](https://angular.io/cli) page. 28 | -------------------------------------------------------------------------------- /inventory-management-app/inventory-mgmt-ui/package.json: -------------------------------------------------------------------------------- 1 | { 2 | "name": "inventory-mgmt-ui", 3 | "version": "0.0.0", 4 | "scripts": { 5 | "ng": "ng", 6 | "start": "ng serve", 7 | "build": "ng build", 8 | "watch": "ng build --watch --configuration development", 9 | "test": "ng test" 10 | }, 11 | "private": true, 12 | "dependencies": { 13 | "@angular/animations": "^15.1.0", 14 | "@angular/cdk": "^15.1.2", 15 | "@angular/common": "^15.1.0", 16 | "@angular/compiler": "^15.1.0", 17 | "@angular/core": "^15.1.0", 18 | "@angular/forms": "^15.1.0", 19 | "@angular/material": "^15.1.2", 20 | "@angular/platform-browser": "^15.1.0", 21 | "@angular/platform-browser-dynamic": "^15.1.0", 22 | "@angular/router": "^15.1.0", 23 | "rxjs": "~7.8.0", 24 | "tslib": "^2.3.0", 25 | "zone.js": "~0.12.0" 26 | }, 27 | "devDependencies": { 28 | "@angular-devkit/build-angular": "^15.1.3", 29 | "@angular/cli": "~15.1.3", 30 | "@angular/compiler-cli": "^15.1.0", 31 | "@types/jasmine": "~4.3.0", 32 | "jasmine-core": "~4.5.0", 33 | "karma": "~6.4.0", 34 | "karma-chrome-launcher": "~3.1.0", 35 | "karma-coverage": "~2.2.0", 36 | "karma-jasmine": "~5.1.0", 37 | "karma-jasmine-html-reporter": "~2.0.0", 38 | "typescript": "~4.9.4" 39 | } 40 | } -------------------------------------------------------------------------------- /inventory-management-app/inventory-mgmt-ui/src/app/app-routing.module.ts: -------------------------------------------------------------------------------- 1 | import { NgModule } from '@angular/core';
