Custom Widgets API Reference

Last modified: 17 December 2019

Add a reference to the dashboard script on unpkg in the header of your index.html file. Wrap the reference inside a <script> tag. For example:
```
<script src="https://unpkg.com/hub-dashboard-addons@latest"></script>
```
Use the npm package manager to install the script with the npm install hub-dashboard-addons command. You can then add references to the script in your widget any way you want.

The Dashboard.registerWidget function accepts a callback that is called with the dashboardAPI and registerWidgetAPI parameters as shown in the following code sample. To view this sample in context, refer to the Create the Script.

// Register widget:
Dashboard.registerWidget(function (dashboardAPI, registerWidgetAPI) {
    // Load GitHub profile data
    loadAndRenderUser(USER_NAME)

    // Set the widget title
    .then(user => dashboardAPI.setTitle(`GitHub User ${user.login}`));

    // Add the refresh button.
    registerWidgetAPI({
        onRefresh: () => loadAndRenderUser(USER_NAME)
    });
});

Dashboard API

Use the dashboard API to communicate with the widget wrapper and the dashboard. All of these methods are asynchronous and return Promise objects. These methods are applied to the dashboardApi object.

setTitle(label: string, ?labelUrl: string): void
Description	Sets the text that is displayed in the widget header. If a value is specified for the `labelUrl` parameter, the text is set as a link to the target URL.
Parameters	`label`	The text string that is shown as the widget title.
Parameters	`labelURL`	The address of the target page that opens when a user clicks the widget title. If this optional parameter is not specified, the widget title is set as text only.
Example	`dashboardApi.setTitle('Some widget'); dashboardApi.setTitle('A link header', 'https://example.com');`

setLoadingAnimationEnabled(enabled: boolean): void
Description	Toggles the image rotation animation for the widget reload icon. Call this method when the widget populates data from a remote server to indicate that a process is running in the background.
Parameters	`enabled`	Determines whether the widget reload icon rotates or not.

alert(message: string, ?type: string, ?timeout: number): string
Description	Displays a system alert at the top of the page.
Parameters	`message`	Sets the text that is displayed as the system alert.
	`type`	Determines which notification style is applied to the alert. Possible values include `error`, `message`, `success`, and `warning`.
	`timeout`	The amount of time the alert is shown on the page, in seconds.
Example	`dashboardApi.alert('This is a standard notification', 'message'); dashboardApi.alert('This is an error', 'error', 10000);`

enterConfigMode(): void
Description	Invokes configuration mode. When in configuration mode, the visual presentation of the widget changes to indicate that its settings can be updated. The refresh icon is also hidden.

exitConfigMode(): void
Description	Exits configuration mode.

storeCache(cache: Object): Promise<Void>
Description	Stores any object in the client-side cache. Use this method to store populated data locally and display it immediately on the dashboard, then refresh it from server. Returns a configuration object.
Parameters	`cache`	Specifies the object to be stored in the cache.

readCache(): Promise<Object>
Description	Reads and returns the object that was previously stored in the cache.

storeConfig(config: Object): Promise<Void>
Description	Stores any object as a widget configuration. Exits configuration mode if configuration mode is active.
Parameters	`config`	Specifies the object to be stored as a widget configuration.

readConfig(): Promise<Object>
Description	Reads and returns the object that was previously stored as a configuration object.

fetch(serviceID: string, url: string, fetchConfig: Object): Promise<Object>
Description	Makes an authorized request to the specified service. The service must be specified in the widget manifest.
Parameters	`serviceID`	Specifies the ID of the service. To get the service ID, use fetchHub first. For details, refer to the Hub REST API.
	`url`	Sets the URL to the service API endpoint. This is the path to the resource that you want to fetch. The URL is relative to the server home URL.
	`fetchConfig`	Defines an optional options object. This object contains any custom settings that you want to apply to the request.
Example	`dashboardApi.fetch(serviceId, 'api/users') .then(users => console.log(users));` The following example shows how to use this method in a POST request: `dashboardApi.fetch(serviceId, 'api/users', { method: 'POST', body: {payload: 'test'} }) .then(result => console.log(result));`

fetchHub(url: string, fetchConfig: Object): Promise<Object>
Description	Makes an authorized request to the Hub service.
Parameters	`url`	Sets the URL to the Hub service API endpoint. This is the path to the resource that you want to fetch. The URL is relative to the server home URL. For more information, refer to the Hub documentation.
Parameters	`fetchConfig`	Defines an optional options object. This object contains any custom settings that you want to apply to the request.
Example	`dashboardApi.fetchHub('api/rest/users/me?fields=name,login,profile(avatar(url))') .then(response => console.log(response));` The following example shows how to use this method in a POST request: `dashboardApi.fetchHub('api/rest/users/me', { method: 'POST', body: {favoriteProjects: []} }) .then(response => console.log(response));`

loadServices(applicationName: string): Promise<Array<Object>>
Description	Returns a list of services that are connected to the Hub service and meet the minimum version requirements that are specified in the `dependencies` section of the `manifest.json` file for the widget. If the service that is specified with the `applicationName` parameter is not referenced in the `dependencies` section of the widget manifest, an exception is thrown. If the specified service that is connected to the Hub service does not meet the minimum version requirements, returns an empty array.
Parameters	`applicationName`	Determines which services are checked against the `dependencies` in the widget manifest.
Example	The following example checks the Hub service for versions of YouTrack that are compatible with the YouTrack versions that are referenced in the `dependencies` section of the widget manifest. The list of compatible versions of the application is printed to the console. `dasboardApi.loadServices('YouTrack') .then(youtracks => console.log(youtracks[0]));`

loadServices(applicationName: string): Promise<Array<Object>>

Description

Returns a list of services that are connected to the Hub service and meet the minimum version requirements that are specified in the dependencies section of the manifest.json file for the widget.

If the service that is specified with the applicationName parameter is not referenced in the dependencies section of the widget manifest, an exception is thrown.
If the specified service that is connected to the Hub service does not meet the minimum version requirements, returns an empty array.

Parameters

applicationName

Determines which services are checked against the dependencies in the widget manifest.

Example

The following example checks the Hub service for versions of YouTrack that are compatible with the YouTrack versions that are referenced in the dependencies section of the widget manifest. The list of compatible versions of the application is printed to the console.

dasboardApi.loadServices('YouTrack')
    .then(youtracks => console.log(youtracks[0]));

removeWidget(): void
Description	Removes the custom widget from the dashboard.

Use the widget API to manipulate the visibility of controls on your custom widget. These methods are applied to the widgetApi object.
