Notification system

Custom Applications have a built-in notification system built on top of Redux.

The @commercetools-frontend/actions-global package provides Redux action creators and React hooks to facilitate dispatching notifications within Custom Applications.

Action creators

Rather than using the action creators directly, we recommend using the corresponding React hooks. The hooks have the dispatch method of the Redux store bound internally.

showNotification

An action creator to dispatch any kind of notification.
Takes 2 arguments: notification object (required) and meta object (optional).

  • notification object properties
PropertyTypeRequiredValuesDefaultDescription
kindstring✅success, error, warning, info, unexpected-error, api-error-The kind of the notification.
domainstring✅side, global, page-The domain of the notification.
textstring---The text content of the notification.

For defining the domain and the kind of a notification we recommend using the values exposed from @commercetools-frontend/constants.

For instance:

import {
  DOMAINS,
  NOTIFICATION_KINDS_SIDE,
} from '@commercetools-frontend/constants';


const kind = NOTIFICATION_KINDS_SIDE.success;
const domain = DOMAINS.SIDE;
  • meta object properties
PropertyTypeRequiredValuesDefaultDescription
dismissAfternumber--5000 (only for the success notification)Delay (in milliseconds) between the appearing and the closing of the notification.
onDismissfunction---Called when the notification closes. Receives notification id as an argument.

showApiErrorNotification

An action creator to dispatch a (page) error notification for API errors of the commercetools HTTP API. Takes as argument an object with errors property, which is an error object or an array of error objects.

Some error sources (for example, GraphQL APIs) return an array or object. The showApiErrorNotification action creator accepts both as the value of errors property.

const errors = [
  {
    message:
      "A duplicate value '\"Test channel\"' exists for field 'key'.",
    code: "DuplicateField",
    extensions: {
      code: "DuplicateField";
    };
  },
];
// ...
dispatch(showApiErrorNotification({ errors })); // dispatch method from Redux store

handleActionError

An action creator that attempts to handle a generic error and dispatch the appropriate (page) notification error if possible. Use this when you simply need to ensure that a notification error is displayed without knowing the exact error.

It takes only one parameter that can be either of these types:

  • API error - an error object containing statusCode and body object
import { STATUS_CODES } from '@commercetools-frontend/constants';
const error = {
  statusCode: STATUS_CODES.FORBIDDEN, // statusCode: 403
  body: {
    message: 'This is an error',
    errors: [
      {
        message: 'This is an error', // this message will be displayed as notification text
        code: 'Invalid',
      },
    ],
  },
};
// ...
dispatch(handleActionError(error)); // dispatch method from Redux store

statusCode: 401 will result in logout of the currently logged user.

statusCode: 404 will be ignored and no notification will be displayed.

If the errors array contains multiple error objects, the displayed notification will contain all error messages.

For example:

const error = {
  // ...
  body: {
    // ...
    errors: [
      {
        message: 'This is the first error', // displayed as the notification text
        code: 'Invalid',
      },
      {
        message: 'This is the second error', // also displayed as the notification text
        code: 'Invalid',
      },
    ],
  },
};
  • an instance of any error extended from Error class
class CustomError extends Error {
  constructor(message) {
    super(message);
    this.name = 'CustomError';
  }
}
const error = new CustomError('error');
dispatch(handleActionError(error)); // dispatch method from Redux store

hideAllPageNotifications

An action creator to hide all active page notifications. Does not take any arguments.

dispatch(hideAllPageNotifications()); // dispatch method from Redux store
