TaskRouter.js v1 Workspace: Managing resources in the browser

The SDK allows developers to interact with the entire TaskRouter REST API by a simple JS API.

Adding the SDK to your application

Include the TaskRouter JS SDK in your JavaScript application as follows:

<script src="https://sdk.twilio.com/js/taskrouter/v1.21/taskrouter.min.js" integrity="sha384-5fq+0qjayReAreRyHy38VpD3Gr9R2OYIzonwIkoGI4M9dhfKW6RWeRnZjfwSrpN8" crossorigin="anonymous"></script>

Creating a TaskRouter Workspace capability token

TaskRouter uses Twilio capability tokens to delegate scoped access to TaskRouter resources to your JavaScript application. Twilio capability tokens conform to the JSON Web Token (JWT) standard, which allow for limited-time use of credentials by a third party. Your web server needs to generate a Twilio capability token and provide it to your JavaScript application in order to register a TaskRouter Workspace.

We provide five helper methods to provide access capabilities (Note: These are not currently available in the Node.js library):

Capability	Authorization
AllowFetchSubresources	A workspace can fetch any subresource
AllowUpdates	A workspace can update its properties
AllowUpdatesSubresources	A workspace can update itself and any subresource
AllowDelete	A workspace can delete itself
AllowDeleteSubresources	A workspace can delete itself and any subresource

Additionally, you can utilize more granular access to particular resources beyond these capabilities. These can viewed under Constructing JWTs.

You can generate a TaskRouter capability token using any of Twilio's Helper Libraries. You'll need to provide your Twilio AccountSid and AuthToken, along with the WorkspaceSid for the Workspace you would like to register. For example, using our PHP helper library you can create a token and add capabilities as follows:

7const util = taskrouter.util;

9const TaskRouterCapability = taskrouter.TaskRouterCapability;
10const Policy = TaskRouterCapability.Policy;
11
12// To set up environmental variables, see http://twil.io/secure
13const accountSid = process.env.TWILIO_ACCOUNT_SID;
14const authToken = process.env.TWILIO_AUTH_TOKEN;
15const workspaceSid = 'WSXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX';
16const workerSid = 'WKXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX';
17
18const TASKROUTER_BASE_URL = 'https://taskrouter.twilio.com';
19const version = 'v1';
20
21const capability = new TaskRouterCapability({
22  accountSid: accountSid,
23  authToken: authToken,
24  workspaceSid: workspaceSid,
25  channelId: workspaceSid,
26});
27
28// Helper function to create Policy
29function buildWorkspacePolicy(options) {
30  options = options || {};
31  const resources = options.resources || [];
32  const urlComponents = [
33    TASKROUTER_BASE_URL,
34    version,
35    'Workspaces',
36    workspaceSid,
37  ];
38
39  return new Policy({
40    url: urlComponents.concat(resources).join('/'),
41    method: options.method || 'GET',
42    allow: true,
43  });
44}
45
46// Event Bridge Policies
47const eventBridgePolicies = util.defaultEventBridgePolicies(
48  accountSid,
49  workspaceSid
50);
51
52const workspacePolicies = [
53  // Workspace Policy
54  buildWorkspacePolicy(),
55  // Workspace subresources fetch Policy
56  buildWorkspacePolicy({ resources: ['**'] }),
57  // Workspace resources update Policy
58  buildWorkspacePolicy({ resources: ['**'], method: 'POST' }),
59  // Workspace resources delete Policy
60  buildWorkspacePolicy({ resources: ['**'], method: 'DELETE' }),
61];
62
63eventBridgePolicies.concat(workspacePolicies).forEach(policy => {
64  capability.addPolicy(policy);
65});
66
67const token = capability.toJwt();

Once you have generated a TaskRouter capability token, you can pass this to your front-end web application and initialize the JavaScript library as follows:

var workspace = new Twilio.TaskRouter.Workspace(WORKSPACE_TOKEN);

The library will raise a 'ready' event once it has connected to TaskRouter:

1workspace.on("ready", function(workspace) {
2  console.log(workspace.sid) // 'WSxxx'
3  console.log(workspace.friendlyName) // 'Workspace 1'
4  console.log(workspace.prioritizeQueueOrder) // 'FIFO'
5  console.log(workspace.defaultActivityName) // 'Offline'
6});

See more about the methods and events exposed on this object below.

Workspace API

TaskRouter.js Workspace exposes the following API:

Twilio.TaskRouter.Workspace

Twilio.TaskRouter.Workspace is the top-level class you'll use for managing a workspace.

new Twilio.TaskRouter.Workspace(workspaceToken)

Parameters

Name	Type	Description
workspaceToken	String	A Twilio TaskRouter capability token. See Creating a TaskRouter capability token for more information.
debug	Boolean	(optional) Whether or not the JS SDK will print event messages to the console. Defaults to true.
region	String	(optional) A Twilio region for websocket connections (ex. `ie1-ix`).
maxRetries	Integer	(optional) The maximum of retries to attempt if a websocket request fails. Defaults to 0.

Sample usage

var workspace = new Twilio.TaskRouter.Workspace(WORKSPACE_TOKEN);

Turning off debugging:

var workspace = new Twilio.TaskRouter.Workspace(WORKSPACE_TOKEN, false);

Methods
