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 | "ng-babylonJS-perf-demo": { 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/ng-babylonJS-perf-demo", 21 | "index": "src/index.html", 22 | "main": "src/main.ts", 23 | "polyfills": "src/polyfills.ts", 24 | "tsConfig": "tsconfig.app.json", 25 | "aot": false, 26 | "assets": [ 27 | "src/favicon.ico", 28 | "src/assets" 29 | ], 30 | "styles": [ 31 | "./node_modules/@angular/material/prebuilt-themes/purple-green.css", 32 | "src/styles.scss" 33 | ], 34 | "scripts": [] 35 | }, 36 | "configurations": { 37 | "production": { 38 | "fileReplacements": [ 39 | { 40 | "replace": "src/environments/environment.ts", 41 | "with": "src/environments/environment.prod.ts" 42 | } 43 | ], 44 | "optimization": true, 45 | "outputHashing": "all", 46 | "sourceMap": false, 47 | "extractCss": true, 48 | "namedChunks": false, 49 | "aot": true, 50 | "extractLicenses": true, 51 | "vendorChunk": false, 52 | "buildOptimizer": true, 53 | "budgets": [ 54 | { 55 | "type": "initial", 56 | "maximumWarning": "2mb", 57 | "maximumError": "5mb" 58 | }, 59 | { 60 | "type": "anyComponentStyle", 61 | "maximumWarning": "6kb", 62 | "maximumError": "10kb" 63 | } 64 | ] 65 | } 66 | } 67 | }, 68 | "serve": { 69 | "builder": "@angular-devkit/build-angular:dev-server", 70 | "options": { 71 | "browserTarget": "ng-babylonJS-perf-demo:build" 72 | }, 73 | "configurations": { 74 | "production": { 75 | "browserTarget": "ng-babylonJS-perf-demo:build:production" 76 | } 77 | } 78 | }, 79 | "extract-i18n": { 80 | "builder": "@angular-devkit/build-angular:extract-i18n", 81 | "options": { 82 | "browserTarget": "ng-babylonJS-perf-demo:build" 83 | } 84 | }, 85 | "test": { 86 | "builder": "@angular-devkit/build-angular:karma", 87 | "options": { 88 | "main": "src/test.ts", 89 | "polyfills": "src/polyfills.ts", 90 | "tsConfig": "tsconfig.spec.json", 91 | "karmaConfig": "karma.conf.js", 92 | "assets": [ 93 | "src/favicon.ico", 94 | "src/assets" 95 | ], 96 | "styles": [ 97 | "./node_modules/@angular/material/prebuilt-themes/purple-green.css", 98 | "src/styles.scss" 99 | ], 100 | "scripts": [] 101 | } 102 | }, 103 | "lint": { 104 | "builder": "@angular-devkit/build-angular:tslint", 105 | "options": { 106 | "tsConfig": [ 107 | "tsconfig.app.json", 108 | "tsconfig.spec.json", 109 | "e2e/tsconfig.json" 110 | ], 111 | "exclude": [ 112 | "**/node_modules/**" 113 | ] 114 | } 115 | }, 116 | "e2e": { 117 | "builder": "@angular-devkit/build-angular:protractor", 118 | "options": { 119 | "protractorConfig": "e2e/protractor.conf.js", 120 | "devServerTarget": "ng-babylonJS-perf-demo:serve" 121 | }, 122 | "configurations": { 123 | "production": { 124 | "devServerTarget": "ng-babylonJS-perf-demo:serve:production" 125 | } 126 | } 127 | } 128 | } 129 | } 130 | }, 131 | "defaultProject": "ng-babylonJS-perf-demo" 132 | } -------------------------------------------------------------------------------- /browserslist: -------------------------------------------------------------------------------- 1 | # This file is used by the build system to adjust CSS and JS output to support the specified browsers below. 2 | # For additional information regarding the format and rule options, please see: 3 | # https://github.com/browserslist/browserslist#queries 4 | 5 | # You can see what browsers were selected by your queries by running: 6 | # npx browserslist 7 | 8 | > 0.5% 9 | last 2 versions 10 | Firefox ESR 11 | not dead 12 | not IE 9-11 # For IE 9-11 support, remove 'not'. -------------------------------------------------------------------------------- /e2e/protractor.conf.js: -------------------------------------------------------------------------------- 1 | // @ts-check 2 | // Protractor configuration file, see link for more information 3 | // https://github.com/angular/protractor/blob/master/lib/config.ts 4 | 5 | const { SpecReporter } = require('jasmine-spec-reporter');
