Navigate to `http://localhost:4200/`. The app 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. Use the `--prod` flag for a production build. 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 [Protractor](http://www.protractortest.org/). 24 | 25 | ## Further help 26 | 27 | To get more help on the Angular CLI use `ng help` or go check out the [Angular CLI README](https://github.com/angular/angular-cli/blob/master/README.md). 28 | -------------------------------------------------------------------------------- /angular.json: -------------------------------------------------------------------------------- 1 | { 2 | "$schema": "./node_modules/@angular/cli/lib/config/schema.json", 3 | "version": 1, 4 | "newProjectRoot": "projects", 5 | "projects": { 6 | "angular-forms-example": { 7 | "root": "", 8 | "sourceRoot": "src", 9 | "projectType": "application", 10 | "prefix": "app", 11 | "schematics": {}, 12 | "architect": { 13 | "build": { 14 | "builder": "@angular-devkit/build-angular:browser", 15 | "options": { 16 | "outputPath": "dist/angular-forms-example", 17 | "index": "src/index.html", 18 | "main": "src/main.ts", 19 | "polyfills": "src/polyfills.ts", 20 | "tsConfig": "src/tsconfig.app.json", 21 | "assets": [ 22 | "src/favicon.ico", 23 | "src/assets" 24 | ], 25 | "styles": [ 26 | { 27 | "input": "node_modules/@angular/material/prebuilt-themes/indigo-pink.css" 28 | }, 29 | "src/styles.scss" 30 | ], 31 | "scripts": [] 32 | }, 33 | "configurations": { 34 | "production": { 35 | "fileReplacements": [ 36 | { 37 | "replace": "src/environments/environment.ts", 38 | "with": "src/environments/environment.prod.ts" 39 | } 40 | ], 41 | "optimization": true, 42 | "outputHashing": "all", 43 | "sourceMap": false, 44 | "extractCss": true, 45 | "namedChunks": false, 46 | "aot": true, 47 | "extractLicenses": true, 48 | "vendorChunk": false, 49 | "buildOptimizer": true 50 | } 51 | } 52 | }, 53 | "serve": { 54 | "builder": "@angular-devkit/build-angular:dev-server", 55 | "options": { 56 | "browserTarget": "angular-forms-example:build" 57 | }, 58 | "configurations": { 59 | "production": { 60 | "browserTarget": "angular-forms-example:build:production" 61 | } 62 | } 63 | }, 64 | "extract-i18n": { 65 | "builder": "@angular-devkit/build-angular:extract-i18n", 66 | "options": { 67 | "browserTarget": "angular-forms-example:build" 68 | } 69 | }, 70 | "test": { 71 | "builder": "@angular-devkit/build-angular:karma", 72 | "options": { 73 | "main": "src/test.ts", 74 | "polyfills": "src/polyfills.ts", 75 | "tsConfig": "src/tsconfig.spec.json", 76 | "karmaConfig": "src/karma.conf.js", 77 | "styles": [ 78 | { 79 | "input": "node_modules/@angular/material/prebuilt-themes/indigo-pink.css" 80 | }, 81 | "src/styles.scss" 82 | ], 83 | "scripts": [], 84 | "assets": [ 85 | "src/favicon.ico", 86 | "src/assets" 87 | ] 88 | } 89 | }, 90 | "lint": { 91 | "builder": "@angular-devkit/build-angular:tslint", 92 | "options": { 93 | "tsConfig": [ 94 | "src/tsconfig.app.json", 95 | "src/tsconfig.spec.json" 96 | ], 97 | "exclude": [ 98 | "**/node_modules/**" 99 | ] 100 | } 101 | } 102 | } 103 | }, 104 | "angular-forms-example-e2e": { 105 | "root": "e2e/", 106 | "projectType": "application", 107 | "architect": { 108 | "e2e": { 109 | "builder": "@angular-devkit/build-angular:protractor", 110 | "options": { 111 | "protractorConfig": "e2e/protractor.conf.js", 112 | "devServerTarget": "angular-forms-example:serve" 113 | }, 114 | "configurations": { 115 | "production": { 116 | "devServerTarget": "angular-forms-example:serve:production" 117 | } 118 | } 119 | }, 120 | "lint": { 121 | "builder": "@angular-devkit/build-angular:tslint", 122 | "options": { 123 | "tsConfig": "e2e/tsconfig.e2e.json", 124 | "exclude": [ 125 | "**/node_modules/**" 126 | ] 127 | } 128 | } 129 | } 130 | } 131 | }, 132 | "defaultProject": "angular-forms-example" 133 | } 134 | -------------------------------------------------------------------------------- /e2e/protractor.conf.js: -------------------------------------------------------------------------------- 1 | // Protractor configuration file, see link for more information 2 | // https://github.com/angular/protractor/blob/master/lib/config.ts 3 | 4 | const { SpecReporter } = require('jasmine-spec-reporter');
