Updating from Ionic 5 to 6

注記

This guide assumes that you have already updated your app to the latest version of Ionic 5. Make sure you have followed the Updating to Ionic 5 Guide before starting this guide.

Breaking Changes

For a complete list of breaking changes from Ionic 5 to Ionic 6, please refer to the breaking changes document in the Ionic Framework repository.

Getting Started

Angular

Ionic 6 supports Angular 12+. Update to the latest version of Angular by following the Angular Update Guide.
Update to the latest version of Ionic 6:

npm install @ionic/angular@6

If you are using Ionic Angular Server, be sure to update that as well:

npm install @ionic/angular@6 @ionic/angular-server@6

Remove any usage of Config.set(). Instead, set your config in IonicModule.forRoot(). See the Angular Config Documentation for more examples.
Remove any usage of the setupConfig function previously exported from @ionic/angular. Set your config in IonicModule.forRoot() instead.

React

Ionic 6 supports React 17+. Update to the latest version of React:

npm install react@latest react-dom@latest

Update to the latest version of Ionic 6:

npm install @ionic/react@6 @ionic/react-router@6

Update the test field in the scripts object of your package.json to include transformIgnorePatterns:

"scripts": {
  "test": "react-scripts test --transformIgnorePatterns 'node_modules/(?!(@ionic/react|@ionic/react-router|@ionic/core|@stencil/core|ionicons)/)'",
  ...
}

Import and call setupIonicReact in your App component file. If you are also using setupConfig, pass your config to setupIonicReact instead:

Before

App.tsx
import { setupConfig } from '@ionic/react';

...

setupConfig({
  mode: 'md'
});

After

App.tsx
import { setupIonicReact } from '@ionic/react';

...

setupIonicReact({
  mode: 'md'
});

注記

Developers must import and call setupIonicReact even if they are not setting custom config.

See the React Config Documentation for more examples.

Update all controller imports from @ionic/core to @ionic/core/components. As an example, here is a migration for menuController:

Before

import { menuController } from '@ionic/core';

After

import { menuController } from '@ionic/core/components';

Vue

Ionic 6 supports Vue 3.0.6+. Update to the latest version of Vue:

npm install vue@3 vue-router@4

For apps that use the Vue CLI, install Vue CLI 5:

npm install -g @vue/cli@next

Then, upgrade all Vue CLI plugins:

vue upgrade --next

Update to the latest version of Ionic 6:

npm install @ionic/vue@6 @ionic/vue-router@6

Add the following transformIgnorePatterns to either jest.config.js or the jest field in package.json:

jest.config.js
module.exports = {
  ...
  transformIgnorePatterns: ['/node_modules/(?!@ionic/vue|@ionic/vue-router|@ionic/core|@stencil/core|ionicons)']
}

package.json
  {
    ...
    "jest": {
      "transformIgnorePatterns": ["/node_modules/(?!@ionic/vue|@ionic/vue-router|@ionic/core|@stencil/core|ionicons)"]
    }
  }

See the Testing section below for more information.

Remove any usage of the setupConfig function previously exported from @ionic/vue. Set your config when installing the IonicVue plugin instead. See the Vue Config Documentation for more examples.
Rename the IonRouter type for useIonRouter to UseIonRouterResult.
Rename the IonKeyboardRef type for useKeyboard to UseKeyboardResult.
Rename any overlay event listeners to use the new format:

Before

<ion-modal
  :is-open="modalOpenRef"
  @onWillPresent="onModalWillPresentHandler"
  @onDidPresent="onModalDidPresentHandler"
  @onWillDismiss="onModalWillDismissHandler"
  @onDidDismiss="onModalDidDismissHandler"
>
  ...
</ion-modal>

After

<ion-modal
  :is-open="modalOpenRef"
  @willPresent="onModalWillPresentHandler"
  @didPresent="onModalDidPresentHandler"
  @willDismiss="onModalWillDismissHandler"
  @didDismiss="onModalDidDismissHandler"
>
  ...
</ion-modal>

注記

This applies to ion-action-sheet, ion-alert, ion-loading, ion-modal, ion-picker, ion-popover, and ion-toast.

Pass in an ion-router-outlet into any ion-tabs that are being used:

Before

<ion-tabs>
  <ion-tab-bar slot="bottom"> ... </ion-tab-bar>
</ion-tabs>

<script>
  import { IonTabs, IonTabBar } from '@ionic/vue';
  import { defineComponent } from 'vue';

  export default defineComponent({
    components: { IonTabs, IonTabBar },
  });
</script>

After

<ion-tabs>
  <ion-router-outlet></ion-router-outlet>
  <ion-tab-bar slot="bottom"> ... </ion-tab-bar>
</ion-tabs>

<script>
  import { IonTabs, IonTabBar, IonRouterOutlet } from '@ionic/vue';
  import { defineComponent } from 'vue';

  export default defineComponent({
    components: { IonTabs, IonTabBar, IonRouterOutlet },
  });
</script>

Additional routes inside of tabs should be re-written as sibling routes instead of child routes:

Before

const routes: Array<RouteRecordRaw> = [
  {
    path: '/',
    redirect: '/tabs/tab1'
  },
  {
    path: '/tabs/',
    component: Tabs,
    children: [
      {
        path: '',
        redirect: 'tab1'
      },
      {
        path: 'tab1',
        component: () => import('@/views/Tab1.vue'),
        children: {
          {
            path: 'view',
            component: () => import('@/views/Tab1View.vue')
          }
        }
      },
      {
        path: 'tab2',
        component: () => import('@/views/Tab2.vue')
      },
      {
        path: 'tab3',
        component: () => import('@/views/Tab3.vue')
      }
    ]
  }
]

After

const routes: Array<RouteRecordRaw> = [
  {
    path: '/',
    redirect: '/tabs/tab1',
  },
  {
    path: '/tabs/',
    component: Tabs,
    children: [
      {
        path: '',
        redirect: 'tab1',
      },
      {
        path: 'tab1',
        component: () => import('@/views/Tab1.vue'),
      },
      {
        path: 'tab1/view',
        component: () => import('@/views/Tab1View.vue'),
      },
      {
        path: 'tab2',
        component: () => import('@/views/Tab2.vue'),
      },
      {
        path: 'tab3',
        component: () => import('@/views/Tab3.vue'),
      },
    ],
  },
];

Core

Update to the latest version of Ionic 6:

npm install @ionic/core@6

Updating Your Code

Datetime

Remove any usages of the placeholder, pickerOptions, pickerFormat, monthNames, monthShortNames, dayNames, and dayShortNames properties. ion-datetime now automatically formats the month names, day names, and time displayed inside of the component according to the language and region set on the device. See the ion-datetime Localization Documentation for more information.
Remove any usages of the text and placeholder CSS Shadow Parts.
Remove any usages of the --padding-bottom, --padding-end, --padding-start, --padding-top, and --placeholder-color CSS Variables. To customize the padding on ion-datetime, you can use any of the padding CSS properties.
Remove any usage of the open method. To present the datetime in an overlay, place it inside of an ion-modal or an ion-popover component. See the ion-datetime Usage Examples for more information.
Remove any usage of the displayFormat or displayTimezone properties. To parse the UTC string provided in the payload of the ionChange event, we recommend using date-fns. See the ion-datetime Parsing Dates Documentation for examples.

注記

See the Datetime Migration Sample Application for more migration examples.

Icon

Ionic 6 now ships with Ionicons 6. Review the Ionicons 6 Breaking Changes Guide and make any necessary changes.

Input

Ensure null is not passed in as a value to the placeholder property. We recommend using undefined instead.

ion-modal now uses the Shadow DOM. Update any styles targeting the internals of ion-modal to use either the ion-modal CSS Variables or the ion-modal CSS Shadow Parts:

Before

ion-modal .modal-wrapper {
  /* Any custom styles here */
}

ion-modal ion-backdrop {
  /* Any custom styles here */
}

After

ion-modal::part(content) {
  /* Any custom styles here */
}

ion-modal::part(backdrop) {
  /* Any custom styles here */
}

ion-popover now uses the Shadow DOM. Update any styles targeting the internals of ion-popover to use either ion-popover CSS Variables or the ion-popover CSS Shadow Parts:

Before

ion-popover .popover-arrow {
  /* Any custom styles here */
}

ion-popover ion-backdrop {
  /* Any custom styles here */
}

ion-popover .popover-content {
  /* Any custom styles here */
}

After

ion-popover::part(arrow) {
  /* Any custom styles here */
}

ion-popover::part(backdrop) {
  /* Any custom styles here */
}

ion-popover::part(content) {
  /* Any custom styles here */
}

Radio

Remove any usage of the RadioChangeEventDetail interface.

Select

Ensure null is not passed in as a value to the placeholder property. We recommend using undefined instead.

Textarea

Ensure null is not passed in as a value to the placeholder property. We recommend using undefined instead.

Browser Support

The list of browsers that Ionic supports has changed. Review the Browser Support Guide to ensure you are deploying apps to supported browsers.

If you have a browserslist or .browserslistrc file, update it with the following content:

Chrome >=60
Firefox >=63
Edge >=79
Safari >=13
iOS >=13

Testing

Ionic 6 now ships as ES Modules. ES Modules are supported in all major browsers and bring developer experience and code maintenance improvements. Developers testing with Jest will need to update their Jest configuration as Jest does not have full support for ES Modules as of Jest 27.

This update involves using Babel to compile Ionic's ES Modules down to the CommonJS (CJS) format, a format that Jest can understand. Once Jest ships support for ES Modules, this change will no longer be necessary. See https://github.com/facebook/jest/issues/9430 for updates on ES Modules support in Jest.

If you are starting fresh with a new Ionic app, this configuration is done for you in our starter applications. For those with existing Ionic apps, follow the steps below to get Jest working with Ionic 6:

Add a transformIgnorePatterns field to your Jest config that includes the relevant Ionic packages. This is typically found in jest.config.js or the jest field in package.json:

jest.config.js
module.exports = {
  ...
  transformIgnorePatterns: ['/node_modules/(?!@ionic/core|@stencil/core|ionicons)']
}

package.json
  {
    ...
    "jest": {
      "transformIgnorePatterns": ["/node_modules/(?!@ionic/core|@stencil/core|ionicons)"]
    }
  }

注記

If you are using Ionic React or Ionic Vue, be sure to add the appropriate packages to the transformIgnorePatterns array. For Ionic React this includes @ionic/react and @ionic/react-router. For Ionic Vue this includes @ionic/vue and @ionic/vue-router.

For developers using Create React App (CRA), there is currently no way to update the transformIgnorePatterns in a Jest config file. This is a CRA restriction and not something Ionic has control over. We can, however, pass the transformIgnorePatterns directly into the react-scripts test command:

package.json
"scripts": {
  "test": "react-scripts test --transformIgnorePatterns 'node_modules/(?!(@ionic/react|@ionic/react-router|@ionic/core|@stencil/core|ionicons)/)'",
  ...
}

If you are still running into issues, here are a couple things to try:

Verify that @babel/preset-env is included in your project-wide configuration instead of your file-relative configuration. This typically means defining the Babel configuration in <project-root>/babel.config.json.
If you have a browserslist/test field in package.json file, make sure it is set to current node.
