Enrico Sacchetti c0d037dfca feat!: initial pre-release - Carbon v11 styles (#1881)
**carbon-components-svelte has unstable styles and interactions during this pre-release phase. See #1872 for details.**

Breaking changes

- Overall, this is a major style change the will impact the appearance and features of many components. Use caution when upgrading and test your applications.

Components

- Button has new prop values for size and kind
- Theme follows v11 conventions: g80 theme isn't supported, toggled themes adjust data-carbon-theme attribute in <html> tag (for now, tokens use bx prefix, but that may change)
- Tabs has a contained prop instead of type, and a new mobile appearance (scrolling tabs)
- ContentSwitcher size prop no longer supports size="xl"; md is the new default
- MultiSelect no longer supports xl size
- OverflowMenu no longer supports xl size
- Search no longer supports xl size
- TreeView no longer supports compact size
- UIShell has a new light theme

CSS

- Several class names have been changed due to the v11 overhaul. If you're targeting or overriding component classes, be sure to test your code
- Many tokens and CSS variables have been renamed. Details: https://carbondesignsystem.com/migrating/guide/develop
- Themes are applied to the <html> element as data-carbon-theme="g10" instead of theme="g10"
- The g80 theme no longer exists

General

- Codebase uses npm instead of yarn

--- Commit notes

* chore: depend on @carbon/styles instead of carbon-components

See upgrade guide here: https://carbondesignsystem.com/migrating/guide/develop

* chore: use v11 styles for docs

* chore: stick to `bx` instead of `cds` class prefix

* chore: migrate layout spacing to v11

See [@carbon/layout](https://github.com/carbon-design-system/carbon/blob/main/docs/migration/v11.md#carbonlayout) migration guide:

    $layout-01 	Removed, use $spacing-05 instead
    $layout-02 	Removed, use $spacing-06 instead
    $layout-03 	Removed, use $spacing-07 instead
    $layout-04 	Removed, use $spacing-09 instead
    $layout-05 	Removed, use $spacing-10 instead
    $layout-06 	Removed, use $spacing-12 instead
    $layout-07 	Removed, use $spacing-13 instead

* chore: migrate type tokens to v11

See https://github.com/carbon-design-system/carbon/blob/main/docs/migration/v11.md#type-tokens

* chore: keep flex-grid instead of css grid for the moment

Upgrading to css-grid should be separate.

* chore: v11 Tabs

In v11 [Tabs](https://carbondesignsystem.com/migrating/guide/design/#tabs-breaking) received some additional modifiers. In this commit we only want to make sure that the Svelte v10 tabs still work using v11 styles. This probably needs additional testing.

* chore: use @ibm/plex fonts

* chore: v11 Button

* dependency: @carbon/styles update

* chore: v11 ComboBox

Size `xl` changed to `lg`. For better compatibility with existing codebases size `xl` is still supported.

* chore: v11 ContentSwitcher

For better compatibility with existing code bases size `xl` is still supported.

`cols` no longer has a defaults to 50 but remains at 100% width by default.

* chore: v11 TextInput

Size `xl` changed to `lg`. For better compatibility with existing codebases size `xl` is still supported.

* chore: v11 TimePicker

Size `xl` changed to `lg`. For better compatibility with existing codebases size `xl` is still supported.

Carbon Components Svelte is a Svelte component library that implements the Carbon Design System, an open source design system by IBM.

Design systems facilitate design and development through reuse, consistency, and extensibility.

The Carbon Svelte portfolio also includes:

Documentation

Other forms of documentation are auto-generated:

Installation

Install carbon-components-svelte as a development dependency.

# Yarn
yarn add -D carbon-components-svelte

# npm
npm i -D carbon-components-svelte

# pnpm
pnpm i -D carbon-components-svelte

Usage

Styling

Before importing components, you will need to first apply Carbon component styles. The Carbon Design System supports four themes (2 light, 2 dark).

  • white.css: Default Carbon theme (light)
  • g10.css: Gray 10 theme (light)
  • g90.css: Gray 90 theme (dark)
  • g100.css: Gray 100 theme (dark)
  • all.css: All themes (White, Gray 10, Gray 90, Gray 100) using CSS variables

Each StyleSheet is generated from the flagship carbon-components library.

The compiled CSS is generated from the following .scss files:

CSS StyleSheet

// White theme
import "carbon-components-svelte/css/white.css";

// Gray 10 theme
import "carbon-components-svelte/css/g10.css";

// Gray 90 theme
import "carbon-components-svelte/css/g90.css";

// Gray 100 theme
import "carbon-components-svelte/css/g100.css";

// All themes
import "carbon-components-svelte/css/all.css";

CDN

An alternative to loading styles is to link an external StyleSheet from a Content Delivery Network (CDN) like unpkg.com.

This is best suited for rapid prototyping.

HTML
<!DOCTYPE html>
<html>
  <head>
    <link
      rel="stylesheet"
      href="https://unpkg.com/carbon-components-svelte/css/white.css"
    />
  </head>
</html>
svelte:head
<svelte:head>
  <link
    rel="stylesheet"
    href="https://unpkg.com/carbon-components-svelte/css/white.css"
  />
</svelte:head>

SCSS

The most performant method to load styles is to import SCSS directly from carbon-components. Although it requires more set up, you can reduce the size of the bundle CSS by importing individual component styles instead of a pre-compiled CSS StyleSheet.

Refer to the official Carbon guide on SASS for documentation.

Dynamic theming

Use the "all.css" StyleSheet for dynamic, client-side theming.

import "carbon-components-svelte/css/all.css";

Update the theme by setting the theme attribute on the html element. The default theme is "white".

<!DOCTYPE html>
<html lang="en" theme="g10">
  <body>
    ...
  </body>
</html>

Programmatically switch between each of the five Carbon themes by setting the "theme" attribute on the HTML element.

<script>
  let theme = "white"; // "white" | "g10" | "g90" | "g100"

  $: document.documentElement.setAttribute("theme", theme);
</script>

Importing components

Import components from carbon-components-svelte in the script tag of your Svelte file. Visit the documentation site for examples.

<!-- App.svelte -->
<script>
  import { Accordion, AccordionItem } from "carbon-components-svelte";
</script>

<Accordion>
  <AccordionItem title="Section 1" open> Content 1 </AccordionItem>
  <AccordionItem title="Section 2"> Content 2 </AccordionItem>
  <AccordionItem title="Section 3"> Content 3 </AccordionItem>
</Accordion>

Refer to COMPONENT_INDEX.md for component API documentation.

Preprocessors

carbon-preprocess-svelte is a collection of Svelte preprocessors for Carbon.

# Yarn
yarn add -D carbon-preprocess-svelte

# npm
npm i -D carbon-preprocess-svelte

# pnpm
pnpm i -D carbon-preprocess-svelte

optimizeImports

optimizeImports is a script preprocessor that rewrites base imports from Carbon components/icons/pictograms packages to their source Svelte code paths. This can greatly speed up compile times during development while preserving typeahead and autocompletion hinting offered by integrated development environments (IDE) like VSCode.

The preprocessor optimizes imports from the following packages:

Before & After

- import { Button } from "carbon-components-svelte";
- import { Add16 } from "carbon-icons-svelte";
- import { Airplane } from "carbon-pictograms-svelte";
+ import Button from "carbon-components-svelte/src/Button/Button.svelte";
+ import Add16 from "carbon-icons-svelte/lib/Add16.svelte";
+ import Airplane from "carbon-pictograms-svelte/lib/Airplane.svelte";

Usage

// svelte.config.js
import { optimizeImports } from "carbon-preprocess-svelte";

export default {
  preprocess: [optimizeImports()],
};

svelte-preprocess should be invoked before any preprocessor from carbon-preprocess-svelte.

// svelte.config.js
+ import sveltePreprocess from "svelte-preprocess";
import { optimizeImports } from "carbon-preprocess-svelte";

export default {
  preprocess: [
+   sveltePreprocess(),
    optimizeImports()
  ],
};

Examples

TypeScript support

TypeScript definitions are generated by sveld.
