FacadePattern 2 | 3 | This project was generated with [Angular CLI](https://github.com/angular/angular-cli) version 14.1.3. 4 | 5 | ## Development server 6 | 7 | Run `ng serve` for a dev server. Navigate to `http://localhost:4200/`. The application will automatically reload if you change any of the source files. 8 | 9 | ## Code scaffolding 10 | 11 | Run `ng generate component component-name` to generate a new component. 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 | -------------------------------------------------------------------------------- /angular.json: -------------------------------------------------------------------------------- 1 | { 2 | "$schema": "./node_modules/@angular/cli/lib/config/schema.json", 3 | "version": 1, 4 | "newProjectRoot": "projects", 5 | "projects": { 6 | "facade-pattern": { 7 | "projectType": "application", 8 | "schematics": { 9 | "@schematics/angular:component": { 10 | "style": "scss" 11 | } 12 | }, 13 | "root": "", 14 | "sourceRoot": "src", 15 | "prefix": "app", 16 | "architect": { 17 | "build": { 18 | "builder": "@angular-devkit/build-angular:browser", 19 | "options": { 20 | "outputPath": "dist/facade-pattern", 21 | "index": "src/index.html", 22 | "main": "src/main.ts", 23 | "polyfills": "src/polyfills.ts", 24 | "tsConfig": "tsconfig.app.json", 25 | "inlineStyleLanguage": "scss", 26 | "assets": [ 27 | "src/favicon.ico", 28 | "src/assets" 29 | ], 30 | "styles": [ 31 | "src/styles.scss", 32 | "node_modules/primeicons/primeicons.css", 33 | "node_modules/primeng/resources/themes/lara-light-blue/theme.css", 34 | "node_modules/primeng/resources/primeng.min.css" 35 | ], 36 | "scripts": [] 37 | }, 38 | "configurations": { 39 | "production": { 40 | "budgets": [ 41 | { 42 | "type": "initial", 43 | "maximumWarning": "500kb", 44 | "maximumError": "1mb" 45 | }, 46 | { 47 | "type": "anyComponentStyle", 48 | "maximumWarning": "2kb", 49 | "maximumError": "4kb" 50 | } 51 | ], 52 | "fileReplacements": [ 53 | { 54 | "replace": "src/environments/environment.ts", 55 | "with": "src/environments/environment.prod.ts" 56 | } 57 | ], 58 | "outputHashing": "all" 59 | }, 60 | "development": { 61 | "buildOptimizer": false, 62 | "optimization": false, 63 | "vendorChunk": true, 64 | "extractLicenses": false, 65 | "sourceMap": true, 66 | "namedChunks": true 67 | } 68 | }, 69 | "defaultConfiguration": "production" 70 | }, 71 | "serve": { 72 | "builder": "@angular-devkit/build-angular:dev-server", 73 | "configurations": { 74 | "production": { 75 | "browserTarget": "facade-pattern:build:production" 76 | }, 77 | "development": { 78 | "browserTarget": "facade-pattern:build:development" 79 | } 80 | }, 81 | "defaultConfiguration": "development" 82 | }, 83 | "extract-i18n": { 84 | "builder": "@angular-devkit/build-angular:extract-i18n", 85 | "options": { 86 | "browserTarget": "facade-pattern:build" 87 | } 88 | }, 89 | "test": { 90 | "builder": "@angular-devkit/build-angular:karma", 91 | "options": { 92 | "main": "src/test.ts", 93 | "polyfills": "src/polyfills.ts", 94 | "tsConfig": "tsconfig.spec.json", 95 | "karmaConfig": "karma.conf.js", 96 | "inlineStyleLanguage": "scss", 97 | "assets": [ 98 | "src/favicon.ico", 99 | "src/assets" 100 | ], 101 | "styles": [ 102 | "src/styles.scss" 103 | ], 104 | "scripts": [] 105 | } 106 | } 107 | } 108 | } 109 | } 110 | } 111 | -------------------------------------------------------------------------------- /karma.conf.js: -------------------------------------------------------------------------------- 1 | // Karma configuration file, see link for more information 2 | // https://karma-runner.github.io/1.0/config/configuration-file.html 3 | 4 | module.exports = function (config) { 5 | config.set({ 6 | basePath: '', 7 | frameworks: ['jasmine', '@angular-devkit/build-angular'], 8 | plugins: [ 9 | require('karma-jasmine'), 10 | require('karma-chrome-launcher'), 11 | require('karma-jasmine-html-reporter'), 12 | require('karma-coverage'), 13 | require('@angular-devkit/build-angular/plugins/karma') 14 | ], 15 | client: { 16 | jasmine: { 17 | // you can add configuration options for Jasmine here 18 | // the possible options are listed at https://jasmine.github.io/api/edge/Configuration.html 19 | // for example, you can disable the random execution with `random: false` 20 | // or set a specific seed with `seed: 4321` 21 | }, 22 | clearContext: false // leave Jasmine Spec Runner output visible in browser 23 | }, 24 | jasmineHtmlReporter: { 25 | suppressAll: true // removes the duplicated traces 26 | }, 27 | coverageReporter: { 28 | dir: require('path').join(__dirname, './coverage/facade-pattern'), 29 | subdir: '.', 30 | reporters: [ 31 | { type: 'html' }, 32 | { type: 'text-summary' } 33 | ] 34 | }, 35 | reporters: ['progress', 'kjhtml'], 36 | port: 9876, 37 | colors: true, 38 | logLevel: config.LOG_INFO, 39 | autoWatch: true, 40 | browsers: ['Chrome'], 41 | singleRun: false, 42 | restartOnFileChange: true 43 | });
