@blackbaud/auth-client

@blackbaud/auth-client

Provides a client-side library for interacting with Blackbaud authentication.

Installation

• Ensure that you have Node v6+ and NPM v3+. To verify this, run node -v and npm -v at the command line.
• Install the library as a dependency of your project by running npm install @blackbaud/auth-client --save in your project's folder.

Usage

Prerequisites

The auth client library makes extensive use of ES6-style Promises, so in order to support browsers that do not yet have native support for Promises (such as Internet Explorer 11) you will need to include a Promise polyfill such as es6-promise and use the auto-polyfill feature of the library so that Promise is added to the global environment. This will need to be loaded on your page before the auth client library.

ES6/TypeScript

There are two classes available in this package: BBAuth and BBOmnibar. BBAuth allows you to retrieve an auth token from the Blackbaud authentication service, and BBOmnibar allows you to render the omnibar at the top of the page.

You can use these in combination to integrate your application with Blackbaud authentication.

import { BBAuth, BBOmnibar } from '@blackbaud/auth-client';

// Make an initial attempt to get an auth token.  If the user is not currently logged in,
// this code will redirect the browser to Blackbaud's sign-in page.
BBAuth.getToken()
  .then(() => {
    // The user is logged in; load the omnibar.
    BBOmnibar.load({
      serviceName: 'Some service name'
    });

    // Add additional logic to bootstrap the rest of the application.
  });

To make authorized requests to your web service endpoints you will also use the BBAuth.getToken() method to retrieve a token that can be added as a header to your request. Since retrieving a token is an asynchronous operation, this method returns a Promise, so you should wait until the Promise is resolved before making your web request.

import { BBAuth } from '@blackbaud/auth-client';

BBAuth.getToken()
  .then((token: string) => {
    const xhr = new XMLHttpRequest();

    xhr.open('GET', url, true);

    xhr.setRequestHeader('Authorization', 'Bearer ' + token);

    xhr.send();
  });

Vanilla JavaScript/ES5

Auth client is also distributed as a UMD bundle. If you're using ES5 with Node or a tool like Browserify you can require() it:

var BBAuthClient = require('@blackbaud/auth-client');

BBAuthClient.BBOmnibar.load({
  serviceName: 'Some service name'
});

If you're using no module loader at all, then you can load the dist/bundles/auth-client.umd.js file onto your page via a <script> element or concatenated with the rest of your page's JavaScript and access it via the global BBAuthClient variable:

// BBAuthClient is global here.
BBAuthClient.BBOmnibar.load({
  serviceName: 'Some service name'
});
