ngx-facebook-fb

ngx-facebook-fb

ngx-facebook-fb is the same as ngx-facebook but updated for use in Angular 9 projects. Details about this lib are here.

This is a wrapper for the official Facebook JavaScript SDK. It makes it easier to use Facebook SDK with Angular 9+ by providing components, providers and types.

Installation

1. Install via NPM

npm i ngx-facebook-fb

2. Add the Facebook JavaScript SDK to your index.html

<script type="text/javascript" src="https://connect.facebook.net/en_US/sdk.js"></script>

or in your main component (e.g. AppComponent):

import { Component, OnInit, Inject, PLATFORM_ID } from '@angular/core';
import { isPlatformBrowser } from '@angular/common';

class AppComponent implements OnInit {
  constructor(
    @Inject(PLATFORM_ID) private platformId: Object) { }

  ngOnInit() {
    if (isPlatformBrowser(this.platformId)) {
      const tag = document.createElement('script');
      tag.src = "https://connect.facebook.net/en_US/sdk.js";
      document.body.appendChild(tag);
    }
  }
}

Note: The code in file https://connect.facebook.net/en_US/sdk.js uses window object that is unavailable in the Node.js. So if we try to run this code on the server, we can have the errors. SSR won't work. Therefore exclude the usage of the lib on the server using isPlatformBrowser(this.platformId)

3. Import FacebookModule into your app's root module

import { FacebookModule } from 'ngx-facebook-fb';

@NgModule({
  ...
  imports: [
    FacebookModule.forRoot()
  ],
  ...
})
export class AppModule { }

If you only want to use FacebookService only, without using the other components, then you can import it in your app's module instead of FacebookModule.

4. Inject FacebookService and call the init method (optional)

This method must be called before using login or api methods. It is not required for other methods/components.

import { Component, OnInit, Inject, PLATFORM_ID } from '@angular/core';
import { isPlatformBrowser } from '@angular/common';

import { FacebookService, InitParams } from 'ngx-facebook-fb';

export class MyComponentOrService {

  constructor(private fb: FacebookService,
             @Inject(PLATFORM_ID) private platformId: Object
  ) {

    if (isPlatformBrowser(platformId)) {
      let initParams: InitParams = {
        appId: '1234566778',
        xfbml: true,
        version: 'v2.8'
      };
  
      fb.init(initParams);
    }

  }

}

Example Usage

You can view our example project here and/or view its source code here

Example of login with Facebook

import { FacebookService, LoginResponse } from 'ngx-facebook-fb';

@Component(...)
export class MyComponent {

  constructor(private fb: FacebookService) { }

  loginWithFacebook(): void {

    this.fb.login()
      .then((response: LoginResponse) => console.log(response))
      .catch((error: any) => console.error(error));

  }

}

Example of sharing on Facebook

import { FacebookService, UIParams, UIResponse } from 'ngx-facebook-fb';

...

share(url: string) {

  let params: UIParams = {
    href: 'https://github.com/zyra/ngx-facebook-fb',
    method: 'share'
  };

  this.fb.ui(params)
    .then((res: UIResponse) => console.log(res))
    .catch((e: any) => console.error(e));

}

Example of adding a Facebook like button

<fb-like href="https://github.com/zyra/ngx-facebook"></fb-like>

Example of playing a Facebook video

Basic video component usage

<fb-video href="https://www.facebook.com/facebook/videos/10153231379946729/"></fb-video>

Advanced video component usage

<fb-video href="https://www.facebook.com/facebook/videos/10153231379946729/" (paused)="onVideoPaused($event)"></fb-video>

import { Component, ViewChild } from '@angular/core';
import { FBVideoComponent } from 'ngx-facebook-fb';

@Component(...)
export class MyComponent {

  @ViewChild(FBVideoComponent) video: FBVideoComponent;

  ngAfterViewInit() {
    this.video.play();
    this.video.pause();
    this.video.getVolume();
  }

  onVideoPaused(ev: any) {
    console.log('User paused the video');
  }
