TaskRouter.js 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:

Loading Code Sample...
 
        

        


        

        


        


        

        

        

        

        

        

        

        

        

        

        
          Creating a TaskRouter Workspace capability token
        
        

        

        

        

        

        

        

        

        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:
        

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

        

        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)
        

        Register a new Twilio.TaskRouter.Workspace with the capabilities provided in workspaceToken.
