RxDB Angular example

This is an example usage of RxDB with Angular. It implements a simple heroes-list which can be filled by the user. Also it uses angular-universal to enable server side rendering.

Try it out

  1. clone the whole RxDB-repo
  2. go into project cd rxdb
  3. run npm install
  4. go to this folder cd examples/angular
  5. run npm run preinstall && npm install
  6. run npm start
  7. Open http://127.0.0.1:4200/ IMPORTANT: do not use localhost

Important parts when using RxDB with angular:

  • Make sure you have the window polyfills added that are needed for pouchdb
// in polyfills.ts
(window as any).global = window;
(window as any).process = {
    env: { DEBUG: undefined },
};
  • Make sure you have used the rxjs-zone.js patch otherwise the change detection will not work properly. For that you should put the following code into your app.component.ts:
//> app.component.ts
/**
 * IMPORTANT: RxDB creates rxjs observables outside of angulars zone
 * So you have to import the rxjs patch to ensure changedetection works correctly.
