ng2-facebook-rxjs

This module enables you to use the Facebook JS SDK through Rx Observables in-line with the rest of your Angular 2 project.

Quick start

1. Install

   npm install ng2-facebook-rxjs --save
   

2. Assuming you are using ng-cli, update angular-cli-build.js

module.exports = function(defaults) {
return new Angular2App(defaults, {
  vendorNpmFiles: [
    'systemjs/dist/system-polyfills.js',
    'systemjs/dist/system.src.js',
    'zone.js/dist/**/*.+(js|js.map)',
    'es6-shim/es6-shim.js',
    'reflect-metadata/**/*.+(ts|js|js.map)',
    'rxjs/**/*.+(js|js.map)',
    '@angular/**/*.+(js|js.map)',
    'ng2-facebook-rxjs/dist/*',
   ]
  });
};

1. Assuming you are using ng-cli, update 'src/system-config.ts`
2. Add ng2-facebook-rxjs into barrels

```
const barrels: string[] = [
  ...
  // Thirdparty barrels.
  'rxjs',
  'ng2-facebook-rxjs',
  ...
];
```

1. Update System.config call

```
System.config({
  map: {
    '@angular': 'vendor/@angular',
    'rxjs': 'vendor/rxjs',
    'ng2-facebook-rxjs': 'vendor/ng2-facebook-rxjs/dist',
    'main': 'main.js'
  },
  packages: cliSystemConfigPackages
});
```

1. Add Facebook's script tag to your index.html file:

<script id="facebook-jssdk" src="//connect.facebook.net/en_US/sdk.js"></script>

1. Use in your code as follows:

import { Component, OnInit, provide } from '@angular/core';  // important to import provide
import { FacebookService, FacebookConfig } from 'ng2-facebook-rxjs';
...  

let fb_config = { appId: "00000000000" };  // use your FB App ID, duh!

...

@Component({
  moduleId: module.id,
  selector: 'sometag',
  providers: [
    FacebookService,
    provide(FacebookConfig, {useValue: fb_config}),
    ],
  ...
})

...

constructor(
  private _facebookService: FacebookService
) {}

login() {
  this._facebookService.login({
              scope: "email,public_profile",
              return_scopes: true
            })
      .subscribe(response => {
        console.log('LOGIN RESPONSE', response);
      })
}

use_api() {
   this._facebookService.api(fb_url)
    .subscribe( response => {
      console.log('API', response);
  
    }, error => {
      console.log('API ERROR', error);
    })
}
