Migration guide​

  • Use of regular expressions in serveSPA.blacklist. If you've been using array of strings, you need to change the syntax to use regular expressions instead:
/* app/environment.js */
{
  ...
- blackList: ['Googlebot', 'SeznamBot'],
+ blackList: userAgent => (new RegExp('Googlebot|SeznamBot', 'g')).test(userAgent),
  ...
}
  • Added new mandatory parameter action to route() method in Router of a type { type: string, event: Event|null, url: string|null }, where type attribute can take one of these values: const { REDIRECT, CLICK, POP_STATE, ERROR } = ActionTypes.
/* ima/Router/ClientRouter.js */
route(
  path,
  options = {},
  { event = null, type = ActionTypes.REDIRECT, url = null } = {}
)

  • Http options withCredentials is set to false by default. You must check your HTTP CORS requests and you must set withCredentials to true for sending Cookie header.

  • New serializer settings in Jest, to configure it first add path to a newly created file jest.setup.js (located in the root directory) into setupFiles array in jest.config.json. After that add new snapshotSerializers field with ["enzyme-to-json/serializer"] value, that handles module loading, which converts Enzyme wrappers into format compatible with Jest snapshots.

/* jest.config.json */
"setupFiles": [
  "ima/test.js",
  "ima/polyfill/imaLoader.js",
  "ima/polyfill/imaRunner.js",
+ "<rootDir>/jest.setup.js"
],
+ snapshotSerializers": ["enzyme-to-json/serializer"]
/* jest.setup.js */
const enzyme = require('enzyme');
const Adapter = require('enzyme-adapter-react-16');

enzyme.configure({ adapter: new Adapter() });

Other changes​

  • IMA.js-helpers - removed throttle and debounce functions. You can replace throttle with throttle method available in UIComponentHelper in IMA.js-ui-atoms package. 73843d0
  • Updated to React 16.7, which along with new context API and other features introduced deprecation of componentWillMount, componentWillReceiveProps and componentWillUpdate lifecycle methods.
  • Upgraded to Babel 7 and latest ESLint 5, which may result on some changes specific to your application.

New Features​

  • Most notable new feature is the introduction of PageManagerHandlers which adds the possibility to customize actions like saving and restoring scroll positions, setting browser's address bar URL etc. For more information visit the documentation.
