Today, I'm thrilled to announce Ionic Framework 5 (Magnesium)! 🎉
This release includes iOS 13 design updates, a brand new API for creating your own custom animations, revamped Ionicons, updated Ionic colors, new starter designs, improvements to component customization, and more!
All of these changes are made in the core of Ionic Framework, which also applies to our Angular, React, and Vue (beta) integrations. Yes, if you haven’t heard yet, we launched our official React support this past October!

Long story short: for those on v4, this upgrade should be easy. Now, let’s dive in and see what’s new!
The largest change in this release is a massive design upgrade across our UI components. Apple recently released iOS 13, which updated the design of many components and thus warranted some updates to our own. Let's check out some of the changes we made to match native iOS!
Due to the nature of this update, there were some breaking changes introduced. Other than any updates related to the breaking changes, no changes need to be made to use the new Segment design. See the Segment documentation for usage information.
iOS introduced the idea of a collapsible header and different sized titles in previous versions. In order to support this, we’ve introduced some properties that can easily be added to the header & title components to get shrinking large titles, small titles, and collapsible buttons.
In order to achieve this, the header needs to be added twice: a header with a standard title above the content, and a collapsible header with a large title inside of the content. In addition to being able to collapse the header, Buttons and a Searchbar inside of the collapsible header can also collapse. See the documentation on Collapsible Large Titles for usage information.
The small title, also known as a header note, is generally used inside of a toolbar above another toolbar that contains a standard-sized title. In native apps, it is most often used in combination with Swipe to Close Modals. See the videos in the section below for a visual representation of the small title.
See the Title documentation for usage information.
In order to enable a swipe to close modal,
presentingElement need to be passed upon modal creation. See the documentation on Swipeable Modals for more information.
No changes need to be made to take advantage of this new menu design. However, if you prefer the old way the menu type can be set back to
Other than moving the placement of the refresher, no changes are needed to use the new pull to refresh. See the Refresher documentation for usage information.
Due to structural changes to support adding lines, it is recommended all text content inside of a List Header be wrapped in an
<ion-label>. Additional information on this can be found in breaking changes.
Other than adding the label and lines if desired, no changes need to be made to enable the new design. See the List Header documentation for usage information. If the old design is desired, use custom CSS to achieve the previous look.
Ionic 5 introduces our brand new open source animations utility, Ionic Animations, that provides the tools developers need to build highly performant animations regardless of the framework they are using. Read more on the Ionic Animations blog.
Ionic 5 ships with the latest version of our free and open source icon library, Ionicons 5, which includes an all-new icon set!
There will immediately be some differences noticed with this upgrade:
- One set of icons for both modes
- Icons come in three new variants: outline, fill (default), and sharp
- Icons will no longer switch between two different icons based on the mode
- The ability to set them per mode will still work, but the icon for each needs to be set using the
- There are still a handful of icons within Ionic that will automatically switch, such as the icon used in menu button, back button and the detail icon on items
- The icon font has been removed from Ionicons, but it does still contain an svg sprite if loading all icons on the same page is needed
For a list of all of the icons that were removed or renamed, see the Ionicons changelog document. To search through all of the newly added icons, check out the Ionicons site. Read more on our Ionicons 5 Announcement blog.
Ionic has been updated with all new colors by default! If your app was not created using one of our starters and you don’t override these colors, you’ll automatically get the new colors in your app. If your app was created using an Angular or React starter, the colors are defined in the
theme/variables.scss file and will need to be updated manually.
We've heard you loud and clear that components are not easy to customize. One reason for this was a lack of available CSS Variables or way to style inner elements. The other reason was due to components being scoped and their Ionic styles taking priority over custom styles. In order to make it easier to style, we've added more CSS variables, converted some scoped components to Shadow DOM, and began adding support for Shadow Parts.
The following components were converted to Shadow DOM:
- Back Button
- Split Pane
Why shadow DOM? One of our biggest reasons for using Shadow DOM is its ability to completely encapsulate styles and prevent them from bleeding into other components. This means we’re able to style specific elements inside of our components without affecting other components that use that element.
In addition to that, Shadow DOM allows us to use CSS custom properties (variables) within the component for easier theming. In previous versions of Ionic Framework, Sass variables were used to customize and theme an app. This requirement not only caused longer build times, but in order to have multiple themes within the same app it required generating multiple CSS files with different Sass variables. CSS variables can be updated at runtime, so an app can change the entire theme based on a CSS class or a prefers-color-scheme media query.
While scoped components allow the use of CSS variables, the selectors that are added to the component make user overrides more difficult, requiring a user to either write an overly complex selector or make use of
!important in the CSS styles in order to override the Ionic components. Additionally, if users were to target an inner element of an Ionic component and we were to change the structure or class, this would break the styling of that element.
With the growing support for Shadow Parts in browsers, users will be able to target specific elements inside of our components to override their styles directly.
For Ionic Angular developers, Ionic 5 will bring full support for Ivy, Angular's new renderer. Ivy enables apps to only require pieces of the renderer that they actually need, instead of the whole thing. This means that our final output will be smaller, which is better for load performance. Read more about Angular Ivy on our blog post.
In the past, a major release of Ionic sometimes caused many breaking changes to the end-user due to internal changes to update the framework it was built on. Our last major release, Ionic 4, was created to avoid this by building Ionic Framework with web components. This has allowed us to only make breaking changes where necessary to improve the framework. A list of all of the breaking changes for this release can be found in our breaking changes document in the
We recommend updating to the latest Ionic 4 release (
4.11.10) to see any deprecation warnings specific to your app in the developer console. After fixing any warnings, it’s as simple as running the following commands:
# for an angular app npm i @ionic/angular@latest --save # for a react app npm i @ionic/react@latest --save npm i @ionic/react-router@latest --save npm i ionicons@latest --save # for a stencil / vanilla JS app npm i @ionic/core@latest --save
Then, head on over to the breaking changes document to see if there were any other changes that need to be made in your app.
As always, we wanted to extend our sincere thanks to the Ionic community. We would not have been able to pull this off without your support. So many of the issues, pull requests, and comments left by community members have been essential to us getting this release out, and for that we're extremely grateful. We hope you’re as excited as we are about this release! Tell us your thoughts below. ⬇️
