Flex UI Configuration

The appConfig.js configuration object detailed below is not directly accessible when using Twilio-hosted Flex (flex.twilio.com). However, all of the same values can be set as ui_attributes using Flex Configuration REST API.

In the configuration object, you can define the default properties of your Flex Components. You can also configure properties that are not tied to specific Components.

Example: public/assets/appConfig.js

1
var appConfig = {
2
  serviceBaseUrl: "https://dancing-owl-1234.twil.io/",
3
  sso: {
4
    accountSid: "ACXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"
5
  },
6
  sdkOptions: {
7
      chat: {},
8
      insights: {},
9
      voice: {},
10
      worker: {}
11
  },
12
  logLevel: "debug",
13
  colorTheme: {
14
    baseName: "GreyDark",
15
    colors: {},
16
    light: false,
17
    overrides: {}
18
  },
19
  componentProps: {
20
    CRMContainer: {
21
      uriCallback: (task) => task
22
        ? `https://www.bing.com/search?q=${task.attributes.name}`
23
        : "http://bing.com"
24
    }
25
  },
26
  router: {
27
    type: "memory",
28
    history: {
29
      initialEntries: [ "/agent-desktop" ]
30
    }
31
  }
32
};

Some configuration options are only available through the configuration object. Below is the list of all available configuration options.

Redefines the color scheme.

1
appConfig.colorTheme = {
2
  baseName: "GreyDark",
3
  colors: { base2: "red"},
4
  light: true,
5
  overrides: {
6
    MainHeader: {
7
      Container: {
8
        background: "green"
9
      }
10
    }
11
  }
12
};

Adjusts the properties of separate Flex Components. For a list of available components, see Components.

1
appConfig.componentProps = {
2
  AgentDesktopView: {
3
    showPanel2: false
4
  }
5
};

Disables conference transfers.

appConfig.disableTransfers = false;

Sets the specificity of log output. Can be either a number or a string matching:

• trace or 0
• debug or 1
• info or 2
• warn or 3
• error or 4
• silent or 5

appConfig.logLevel = 'info';

Whether to load plugins to modify the Flex UI. Provides an optional URL to override Flex's default plugins source.

1
appConfig.pluginService = {
2
  enabled: true,
3
  url: "https://example.com/plugins-list.json"
4
};

Sets the use of browser or in-memory routing for Flex.

1
appConfig.router = {
2
  type: "memory",
3
  history: {
4
    initialEntries: [ "/agent-desktop" ]
5
  }
6
};

Flex initializes four standard Twilio SDKs, which are accessible via the Flex Manager. These sdkOptions will pass through as parameters used when initializing those SDKs. (example: Twilio.Device parameters for voice)

1
appConfig.sdkOptions = {
2
  chat: {},
3
  insights: {},
4
  voice: {},
5
  worker: {}
6
};

Currently not used. This value defaults to the Runtime Domain that is associated with your Twilio Account. This is a reference to Functions you may be hosting to power backend API requests.

Enables support for authentication and Single Sign-On using 3rd party Identity Providers such as Okta.

1
appConfig.sso = { 
2
  accountSid: "ACxxx" // AccountSid of your Twilio project 
3
};

Currently not used.

You may also configure default properties for components within a Plugin by using the React defaultprops API programmatically:

componentProps: { [Component Name]: { [Prop Name]: [PropValue] } }

Example

1
flex.CRMContainer
2
  .defaultProps
3
  .uriCallback = (task) => task
4
    ? `https://www.bing.com/search?q=${task.attributes.name}`
5
    : "http://bing.com/";
6

7
flex.MainHeader
8
  .defaultProps

uri: string

The URI that is displayed in the CRM container. This URI must be generated by the uriCallback.

uriCallback: (task: Task) => string

splitterOptions: object

Allows specification of the default values for the main horizontal splitter in Agent Desktop view (separates the left view from the CRM area to the right). Values can either be pixels or % values.

1
{

initialCompareFunction: (worker1: IWorker, worker2: IWorker) => number
