Guide

Step-by-step guide to updating your code from Carbon v10 to v11.

Overview

This guide helps you update your project to Carbon v11. It is broken into sections based on how you are using Carbon in your project today. For most teams using Carbon, you’ll want to use the Migrating a React app section.

One of the biggest changes to Carbon in v11 is that we moved to dedicated packages under the

@carbon
scope. What this means for you is that if you were previously using the following packages:

  • carbon-components
  • carbon-components-react
  • carbon-icons
  • @carbon/icons-react

You can access all of this work under one single package:

@carbon/react
. This package will re-export all of the styles and icons for Carbon all in one dependency.

If you were previously using

carbon-components
, the styles from this package are available under
@carbon/styles
. They are also re-exported through
@carbon/react

Both the

carbon-components
and
carbon-components-react
packages are now deprecated.

Migrating a React app or library

Starting in v11, the React components for Carbon live in the

@carbon/react
package.

The

@carbon/react
package also includes the styles for Carbon along with icons.

Step 1: Install @carbon/react

To get started, uninstall the following packages if they exist in your project:

  • carbon-components
  • carbon-components-react
  • carbon-icons
  • @carbon/icons-react
npm uninstall carbon-components carbon-components-react carbon-icons @carbon/icons-react

Or, with Yarn:

yarn remove carbon-components carbon-components-react carbon-icons @carbon/icons-react

Next, install the

@carbon/react
package:

npm install @carbon/react

Or, with Yarn:

yarn add @carbon/react

Now that you’ve removed the old packages and brought in the new ones, run the codemod below to fix your pathing.

npx @carbon/upgrade migrate update-carbon-components-react-import-to-scoped --write

After running the command, your code should start looking like this:

// Before
import { Accordion, AccordionItem } from 'carbon-components-react';
// After
import { Accordion, AccordionItem } from '@carbon/react';

For full details, including options and commands availabe when using the

@carbon/upgrade
CLI, see the package documentation.

Step 2: Install Dart Sass

If you were previously importing styles from

carbon-components
, you can now import styles directly from
@carbon/react
or the
@carbon/react/scss
folder.

Before you’re able to bring in these styles, you’ll need to make sure your project is setup to use Dart Sass. Starting in v11, Carbon styles requires Dart Sass through the

sass
package in order to compile. This change comes from our migration to Sass Modules in order to improve our compilation times and overall project structure.

First, let’s remove

node-sass
from your project. If you don’t have
node-sass
, no worries, just skip down and begin adding
sass
.

npm uninstall node-sass

Or, with Yarn:

yarn remove node-sass

Now, let’s install

sass
:

npm install sass --save-dev

Or, with Yarn:

yarn add sass --dev

Once you have Dart Sass installed, it’s important that you configure your project to support resolving imports in Sass from

node_modules
. Typically, this means adding
node_modules
to your
includePaths
config for Sass in your bundler or toolchain of choice.

To learn more about how to configure your specific toolchain to support this, read the documentation for configuration here. We also have published a guide over on Medium to help out with common problems that come from this migration.

Step 3: Update style import paths

Now, open your project’s root stylesheet to make the following changes:

- @import 'carbon-components/scss/globals/scss/styles.scss';
+ @use '@carbon/react';

If you were providing any configuration options before you imported Carbon you can now provide them using the

with
syntax:

@use '@carbon/react' with (
$css--default-type: true,
$css--reset: true
);

If you were using any feature flags in v10, you can safely remove them in v11.

You can also use @import to bring in Carbon, if you prefer, although @use is recommended.

For cases where your projects does’t need to include everything via

@use '@carbon/react'
; and just want to do individual component styles.

// Configure feature flags if needed, if not these
// lines can be removed
@use '@carbon/react/scss/config' with (
$font-path: '@ibm/plex',
$use-flexbox-grid: 'true'
);
// Emit the css reset
@use '@carbon/react/scss/reset';

When migrating your custom components, some of our most used sass assets are included below, along with what you would need to have at the top of your file to use it. Essentially, all we are doing is including the path where we would find these styles in our package.

Carbon sass I’m usingSass modules to include
Type tokens
@use '@carbon/react/scss/type' as *;
Theme tokens
@use '@carbon/react/scss/theme' as *
Theme mixins
@use '@carbon/react/scss/themes' as *
Design language color tokens
@use '@carbon/react/scss/colors' as *
Spacing tokens
@use '@carbon/react/scss/spacing' as *
Breakpoint mixins
@use '@carbon/react/scss/breakpoint' as *
Motion tokens and functions
@use '@carbon/react/scss/motion' as *
Rem and other convert functions
@use '@carbon/react/scss/utilities/convert' as *
Z-index helper
@use '@carbon/react/scss/utilities/z-index' as *
Focus outline helper
@use '@carbon/react/scss/utilities/focus-outline' as *
Transform rotate helper
@use '@carbon/react/scss/utilities/rotate' as *
Skeleton animation helper
@use '@carbon/react/scss/utilities/skeleton' as *

Now that you’ve migrated all of your imports, do a find/replace using your favorite code editor. The prefix

carbon--
is no longer necessary. You can do a find for
carbon--
and replace it with nothing to remove across all your files like the example below. The full list of changes are available in our Migration Docs.

- @include carbon--breakpoint(lg) {
+ @include breakpoint(lg) {
width: 42%;
}

Once you’ve removed the prefix, your styles should all be set using the old, v10 tokens. We recommend teams install the community supported stylelint-plugin-carbon-tokens to further assist in migrating your tokens to v11 tokens as the old v10 tokens will be removed in our next major release.

Step 4: Updating component size props

Components with size variants have been updated to use the same API options. Previously, the size options were inconsistent:

field
,
medium
,
short
. Now, size options fall under the following values:

Prop valueSize
xs
24px
sm
32px
md
40px
lg
48px
xl
64px
2xl
80px

Note: the default size in v11 is

md
(
40px
).

Run the following codemods to update the size prop across the effected components in your project.

npx @carbon/upgrade migrate small-to-size-prop --write
npx @carbon/upgrade migrate size-prop-update --write

By running the series of codemods, they will do the following, in order:

  1. Removes the deprecated
    small
    boolean prop and replaces it with
    size="sm"
    .
  2. Removes v10 size props and replaces them with v11 sizes props.

It’s important to run the npx commands in the order that they are presented above. Doing them out of order might result in the codemod not working as intended.

For full details, including options and commands availabe when using the

@carbon/upgrade
CLI, see the package documentation.

The following components all have size variants that may be affected in your code. To update, you will need to switch to one of the size options listed above. The codemod will make short work of these changes.

  • Accordion
  • Button
  • ComboBox
  • Dropdown
  • Multiselect
  • Filterable multiselect
  • ContentSwitcher
  • DataTable
  • DatePicker
  • FileUploader
  • FileUploaderItem
  • FileUploaderDropContainer
  • FileUploaderButton
  • Link
  • Modal
  • ComposedModal
  • NumberInput
  • OverflowMenu
  • Search
  • Select
  • Tag
  • TextInput
  • TimePicker
  • Toggle

Step 5: Update icon sizes and imports

The

@carbon/icons-react
package has been updated to minimize the number of exports from the package to help reduce build and compile times. This package is available under
@carbon/react/icons
.

This update includes a change to the API of the icon components that come from this package. Previously, we would export icons that included the size of the asset. This update allows you to bring the icon directly and specify the size using the

size
prop.

Run the following codemods to update your project’s icons.

npx @carbon/upgrade migrate icons-react-size-prop --write
npx @carbon/upgrade migrate update-carbon-icons-react-import-to-carbon-react --write

By running the series of codemods, they will do the following, in order:

  1. Removes the size from the import and places it on the icon directly.
  2. Remove the
    @carbon/icons-react
    pathing and replace it with
    @carbon/react/icons
    .

It’s important to run the npx commands in the order that they are presented above. Doing them out of order might result in the codemod not working as intended.

For full details, including options and commands availabe when using the

@carbon/upgrade
CLI, see the package documentation.

After running the command, instead of your icons imports looking like this:

Before

import { Add32, Add24, Add20, Add16 } from '@carbon/icons-react';
function MyComponent() {
return (
<>
<Add32 />
<Add24 />
<Add20 />
<Add16 />

They should start looking like this:

After

import { Add } from '@carbon/react/icons';
function MyComponent() {
return (
<>
<Add size={32} />
<Add size={24} />
<Add size={20} />
<Add />

Removed icons

The following deprecated icons have been removed. Use the table below to find their replacement, if available, in v11.

glyph—circle-strokeGlyphCircleStrokeCircleStroke
glyph—criticalGlyphCriticalCritical
glyph—incompleteGlyphIncompleteIncomplete
glyph—square-fillGlyphSquareFillSquareFill
glyph—undefinedGlyphUndefinedUndefined

However, in certain situations, we will be unable to infer what the correct update should be for a certain usage of the icon component. We have written the codemod to work for most situations, but you will see console warnings for files that will require you to manually review them to make sure the transforms were applied correctly.

The most common manual update that teams will need to make is if a

prop
where the icon is passed to places a
ref
on the icon. For example,

function MyComponent({ renderIcon: Icon }) {
const ref = useRef(null);
return <Icon ref={ref} />;
}
// Before
<MyComponent renderIcon={Search16} />
// After the codemod

In this situation, you will need to update your code to use

React.forwardRef
:

<MyComponent
renderIcon={React.forwardRef((props, ref) => (
<Search ref={ref} size={16} {...props} />
))}
/>;
// Or, alternatively:
const Search16 = React.forwardRef((props, ref) => {
return <Search ref={ref} size={16} {...props} />;

Manual migration

In addition to the automated codemods above, there are several patterns in your codebase that you will need to update manually:

  • If you use the name
    ForwardRef(IconName16)
    in a test you will need to manually change this. Prefer to use the component directly if using enzyme
  • If you use snapshot tests, the structure will change and include a
    size
    prop. Make sure that the
    size
    prop value matches what your icon name used to be. For example,
    <Add16 />
    should become
    <Add size={16} />

Step 6: Update components that have changed

In v11, we have updated the APIs of certain components in one of the following ways:

  • Update
    className
    usage to be applied to the outermost element of a component
  • Remove props that have been deprecated in v10
  • Refactor the API to ship an accessible component

For a full list of changes to components, check out our Migration Docs. Below are some common changes that may impact you and your usage of Carbon.

Changes to
className

The usage of

className
prop has been updated so that the class is passed to the outermost element of a component’s inner markup. This was already the case for most components and this change brings along the remaining components in the library to this convention.

The following components previously were not applying the

className
prop to the outermost element. If you were using a custom
className
to target an inner element for any of these components, you will have to update your selectors to now account for the
className
being placed on the outermost element.

  • Checkbox
  • ComboBox
  • Table
  • TableToolbar
  • DataTableSkeleton
  • DatePicker
  • DatePickerSkeleton
  • DatePickerInput
  • Dropdown
  • FileUploaderDropContainer
  • FileUploaderItem
  • FormGroup
  • FilterableMultiSelect
  • MultiSelect
  • NotificationTextDetails
  • NotificationIcon
  • NumberInput
  • OverflowMenuItem
  • RadioButtonGroup
  • RadioTile
  • Select
  • Slider
  • Switch
  • TextArea
  • ControlledPasswordInput
  • PasswordInput
  • TextInput
  • TimePicker
  • Tooltip
  • HeaderContainer

Notification

We have updated the notification components to be more accessible out of the box.

ToastNotification
and
InlineNotification
now have
role="status"
by default with additional
role
options of
log
and
alert
. These components do not receive focus and should be used for information-only use cases. These components no longer accept actions or interactive children.

For notifications requiring an action, a new

ActionableNotifiation
component is available. It has a
role="alertdialog"
and recieves focus by default. Automatic placement of focus can be turned off via the new
hasFocus
prop.

All notifications have a new optional

closeOnEscape
prop, it enables notifications to closed by pressing the
escape
key. For more details, see the notification components accessibility page.

Update
ToastNotification
usage

  • children
    can no longer contain interactive elements. A
    ToastNotification
    containing an action or interactive children should be replaced with
    ActionableNotification
    .
  • The
    notificationType
    prop is no longer needed and can be removed.
  • The default
    role
    is now
    status
    .
    log
    and
    alert
    can also be used.
  • The
    closeOnEscape
    prop toggles the closing of notifications via the
    escape
    key.

Update
InlineNotification
usage

  • The
    actions
    prop has been removed. An
    InlineNotification
    containing an action or interactive children should be replaced with
    ActionableNotification
    configured with the
    inline
    prop.
  • children
    can no longer contain interactive elements.
  • The
    notificationType
    prop is no longer needed and can be removed.
  • The default
    role
    is now
    status
    .
    log
    and
    alert
    can also be used.
  • The
    closeOnEscape
    prop toggles the closing of notifications via the
    escape
    key.

When using
ActionableNotification
:

  • The
    inline
    prop enables a styling variation resulting in a similar visual design to
    InlineNotification
    .
  • The
    actionButtonLabel
    prop configures the action button text.
  • The
    hasFocus
    prop toggles the automatic placement of focus.
  • The
    closeOnEscape
    prop toggles the closing of notifications via the
    escape
    key.

Tabs

Tabs have been updated to be more composable so that you have the flexibity and control to make them look and act how you want.

In v10, you may have code that looks like the following:

<Tabs>
<Tab label="Tab label 1">
<p>Content for first tab goes here.</p>
</Tab>
<Tab label="Tab label 2">
<p>Content for second tab goes here.</p>
</Tab>
<Tab label="Tab label 3" disabled>
<p>Content for third tab goes here.</p>

Those same Tabs, migrated to v11:

<Tabs>
<TabList>
<Tab>Tab Label 1</Tab>
<Tab>Tab Label 2</Tab>
<Tab disabled>Tab Label 3</Tab>
<Tab title="Tab Label 4 shows truncation">Tab Label 4 shows truncation</Tab>
</TabList>
<TabPanels>
<TabPanel>Content for first tab goes here.</TabPanel>

Update
Tabs
and
Tab
usage

All the same functionality for Tabs is available in v11 and more! However, some props have been deprecated because they have either been renamed or are no longer needed. Below are the minor tweaks in naming or implementation.

  • the
    type
    prop is deprecated. Both “contained” and “default” tabs still exist but now can be called by adding the prop
    contained
    to the
    TabList
    .
  • Default tabs are now referred to as line tabs in our documentation here and in our storybook.
  • hidden
    prop is no longer needed with the new composable Tabs. You have control over tab content and when it is hidden through the
    TabPanel
    and
    TabPanels
    components.
  • selected
    prop is now named
    selectedIndex
    .
  • tabContentClassName
    is no longer needed.
    TabPanel
    (equivalent to tab content) takes in a className prop on its outermost node.
  • For
    Tab
    ,
    label
    is no longer needed.
    children
    of
    Tab
    are now the label.
  • Due to its composability,
    renderAnchor
    ,
    renderButton
    ,
    renderContent
    are no longer needed on
    Tab
    . You now have full control over what is rendered inside of
    Tab
    and
    TabPanel
    .
  • Because
    renderButton
    is no longer needed, the associated
    tabIndex
    prop has also been deprecated.
  • selected
    on
    Tab
    is deprecated in favor or
    selectedIndex
    , now placed on
    Tabs
    instead.

For more details about the changes to Tabs, see our storybook documentation here.

Step 7: Done with @carbon/react!

And that’s it! You’re done. At this point you have migrated to use Carbon v11 using the

@carbon/react
package.

If you run into any problems after this point, please feel free to reach out to us over on Slack or open up a discussion on GitHub. We want to make this migration experience as seamless as possible and will be monitoring both areas to help out.

Migrating an app or library using just styles

Starting in v11, the styles for Carbon live in the

@carbon/styles
package. Alternatively, you can continue to use
carbon-components
as it re-exports styles from this package directly.

For teams using Svelte, Angular, Vue, LWC, or Web Components, please review the documention, for those respective frameworks before making the migration to v11.

Step 1: Install @carbon/styles

To get started, uninstall

carbon-components
from your project:

npm uninstall carbon-components

Or, with Yarn:

yarn remove carbon-components

Next, install the

@carbon/styles
package:

npm install @carbon/styles

Or, with Yarn:

yarn add @carbon/styles

Step 2: Install and configure Dart Sass

Previously,

carbon-components
supported being compiled by different Sass libraries. Starting in v11, the
@carbon/styles
package requires Dart Sass through the
sass
package in order to compile. This change comes from our migration to Sass Modules in order to improve our compilation times and overall project structure.

If you don’t have this dependency already in your project, you can install it:

npm install sass

Or, with Yarn:

yarn add sass

Similarly, if you currently use

node-sass
now is a good time to remove that dependency from your project. In most situations, Dart Sass is a drop-in replacement for
node-sass
and should require no changes on your end in order to use it once you install the dependency.

One you have Dart Sass installed, it’s important that you configure your project to support resolving imports in Sass from

node_modules
. Typically, this means adding
node_modules
to your
includePaths
config for Sass in your bundler or toolchain of choice.

To learn more about how to configure your specific toolchain to support this, read the documentation for configuration here. We also have published a guide over on Medium to help out with common problems that come from this migration.

Step 3: Update import paths and tokens

Now, open your project’s root stylesheet to make the following changes:

- @import 'carbon-components/scss/globals/scss/styles.scss';
+ @use '@carbon/styles';

If you were providing any configuration options before you imported Carbon you can now provide them using the

with
syntax:

@use '@carbon/styles' with (
$css--default-type: true,
$css--reset: true
);

For cases where your projects does’t need to include everything via

@use '@carbon/styles'
; and just want to do individual component styles.

// configure feature flags if needed, if not this line can be removed
@use '@carbon/styles/scss/config' with (
$font-path: '@ibm/plex'
);
// ensure the css reset is included
@use '@carbon/styles/scss/reset';
// add styles for components individually

When migrating your custom components, some of our most used sass assets are included below, along with what you would need to have at the top of your file to use it. Essentially, all we are doing is including the path where we would find these styles in our package.

Carbon sass I’m usingSass modules to include
Theme tokens
@use '@carbon/styles/scss/theme' as *
Theme mixins
@use '@carbon/styles/scss/themes' as *
Design language color tokens
@use '@carbon/styles/scss/colors' as *
Spacing tokens
@use '@carbon/styles/scss/spacing' as *
Breakpoint mixins
@use '@carbon/styles/scss/breakpoint' as *
Motion tokens and functions
@use '@carbon/styles/scss/motion' as *
Rem and other convert functions
@use '@carbon/styles/scss/utilities/convert' as *
Z-index helper
@use '@carbon/styles/scss/utilities/z-index' as *
Focus outline helper
@use '@carbon/styles/scss/utilities/focus-outline' as *
Transform rotate helper
@use '@carbon/styles/scss/utilities/rotate' as *
Skeleton animation helper
@use '@carbon/styles/scss/utilities/skeleton' as *

Now that you’ve migrated all of your imports, do a find/replace using your favorite code editor. The prefix

carbon--
is no longer necessary. You can do a find for
carbon--
and replace it with nothing to remove across all your files like the example below. The full list of changes are available in our Migration Docs.

- @include carbon--breakpoint(lg) {
+ @include breakpoint(lg) {
width: 42%;
}

Once you’ve removed the prefix, your styles should all be set using the old, v10 tokens. We recommend teams install the community supported stylelint-plugin-carbon-tokens to further assist in migrating your tokens to v11 tokens as the old v10 tokens will be removed in our next major release.

Step 4: Update bx to cds

If you are targeting specific selectors that use the

bx
prefix, you will need to update your code to either target the
cds
prefix for selectors or update Carbon’s configuration to use
bx
as the prefix by writing the following:

// Option A
@use '@carbon/styles' with (
$prefix: 'bx'
);
// Option B
@use '@carbon/styles/scss/config' with (
$prefix: 'bx'
);

Step 5: Enable flexbox grid

If you are using the flexbox-based grid in your project, you can continue to use this feature in v11 by importing the following:

@use '@carbon/styles/scss/grid/flexbox';

This is important due to the fact that the CSS Grid implementation is used by default in v11. However, bringing in the flexbox grid styles in this way means that your layouts will continue to work the same as in v10.

Step 6: Done with @carbon/styles!

And that’s it! You’re done. At this point you have migrated to use Carbon v11 using the

@carbon/styles
package.

If you run into any problems after this point, please feel free to reach out to us over on Slack or open up a discussion on GitHub. We want to make this migration experience as seamless as possible and will be monitoring both areas to help out.

Migrating carbon-icons

The

carbon-icons
package has been deprecated and is no longer supported. To use icons from the Carbon Design System, you should install the appropriate library to use with your framework:

PackageFrameworkLink
@carbon/icons-react
ReactLink
@carbon/icons-angular
AngularLink
@carbon/icons-vue
VueLink
carbon-icons-svelte
SvelteLink
@carbon/icons
Vanilla JavaScriptLink

If you are using

@carbon/react
, you can directly import icons from
@carbon/react/icons
.

Migrating Carbon elements

The packages that we ship for the IBM Design Language have been updated in v11. The most notable change is that these packages now require Dart Sass in order to compile as they now use Sass Modules to improve compilation times.

If you were directly importing from one of these element packages, consider importing from either

@carbon/styles
or
@carbon/react
instead. Both of these packages provide entrypoints for elements packages on top of the styles for Carbon itself.

For teams using these packages directly, you will need to update each of the elements packages you’re using to the latest version.

npm install @carbon/<package-name>@latest

Or, with Yarn:

yarn upgrade @carbon/<package-name>@latest

Afterwards, you will need to update the import paths and import names themselves that you bring in. In general, each package now supports importing from the package directly and all

carbon--
prefixed variables, mixins, and functions have been renamed to remove the prefix.

For full details fo the changes to each elements package, check out the links below.

PackageMigration Docs
@carbon/colors
Link
@carbon/elements
Link
@carbon/grid
Link
@carbon/layout
Link
@carbon/motion
Link
@carbon/themes
Link
@carbon/type

If you were previously using the

@carbon/import-once
package, you can continue to use this in v11. However, this package will receive no further updates after Carbon switched to using Sass Modules.
