Navigate to `http://localhost:4200/`. 8 | 9 | 10 | ## How to implement 11 | Please review the commits, I've created step by step commits. 12 | 13 | 14 | ## How to use 15 | After build `npm run build` there will be three js files (inline.bundle.js, main.bundle.js, styles.bundle.js) include them in any html file and you will have access to your web components, created in angular! 16 | 17 | 18 | ## @angular/elements 19 | this package is coppied from angular repository labs/elements branch, it's folder can be removed after this package will be released and will be available on npm 20 | 21 | 22 | ## Summarize 23 | We don't have bootstrap component in AppModule, instead of that we can have any number of entry components and they all will be web components! 24 | 25 | For demonstration I've commented standard app-root component in index.html and placed multiple app-like-button components. 26 | 27 | To create more web components using angular, just generate new component `ng g component my-new-comp` and place in AppModule's entryComponent's list, thats it, really simple :) 28 | 29 | ## Video 30 | [![IMAGE ALT TEXT HERE](https://img.youtube.com/vi/ljsOPm4MMEo/0.jpg)](https://www.youtube.com/watch?v=ljsOPm4MMEo) 31 | -------------------------------------------------------------------------------- /e2e/app.e2e-spec.ts: -------------------------------------------------------------------------------- 1 | import { AppPage } from './app.po';

14 | Angular Logo 16 | Web Components: How to create! 17 |

18 | 19 |
20 | 21 |

Info:

22 |

23 | This application creates web components using Angular Elements, which is not released yet, but it works pretty well, there 24 | is a branch in angular repository: 25 | labs/elements 29 |
30 |
We have three different web components here: 31 |

32 |
    33 |
  • app-like-button 34 | - just one simple component 35 |
    • 36 |
  • app-module-shell 37 | - shell for (minimal version, to be integrated in another systems) 38 |
    • 39 |
  • app-module-root 40 | - this is current page that you are viewing (a.k.a. bootstrap page) 41 |
    • 42 |
43 |
We are using routing also,with MockLocationStrategy to make it isolated from main router, when app-module-shell will be 44 | used in another application. 45 |
46 |
Also you can see how those web components can be used: 47 | https://angular-webcomponents-usage-sample.now.sh/ 51 | 52 | 53 |
