storybook-i18n

Storybook-i18n

A library for best-practice i18n addons in Storybook:

• Easy-to-use locale configuration
• Simple drop-down menu
• URL-linkable state for sharing

Requires storybook ^6.4.17

Addon authors

As an addon author, you can use this library by adding it as a dependency and adding the following to your /preset.js file:

function config(entry = []) {
    return [
        ...entry,
        require.resolve('storybook-i18n/preview'), // <-- library's preview preset
        require.resolve('./dist/esm/preset/preview'), // <-- your addon's preview preset (if present)
    ];
}

function managerEntries(entry = []) {
    return [
        ...entry,
        require.resolve('storybook-i18n/manager'),
        require.resolve('./dist/esm/preset/manager'), // <-- your addon's manager (if present)
    ];
}

module.exports = {config, managerEntries};

The currently selected locale is available in the locale global, so you can access it in a decorator using the following snippet:

import { MyProvider } from 'your-i18n-library';
import { useGlobals } from '@storybook/client-api';

const myDecorator = (story, context) => {
  const [{locale}] = useGlobals();
  
  return <MyProvider locale={locale}>;
}

End users

End users configure the locales and locale parameters in .storybook/preview.js.

locales is an object where the keys are the "ids" of the locale/language and the values are the plain text name of that locale you want to use. This is what will appear in the dropdown in the toolbar.

export const parameters = {
  locale: "en",
  locales: {
    en: "English",
    fr: "Français",
    ja: "日本語",
  },
};

Users can also use full locale strings.

export const parameters = {
  locale: "en_US",
  locales: {
    en_US: "English (US)",
    en_GB: "English (GB)",
    fr_FR: "Français",
    ja_JP: "日本語",
  },
};

The locales object can also have values as an object with keys of title, left, or right.

This is useful if you want to include an emoji flag or some other string to the left or right side.

For example:

export const parameters = {
    locale: "en",
    locales: {
        en: {title: "English", left: '🇺🇸'},
        fr: {title: "Français", left: '🇫🇷'},
        ja: {title: "日本語", left: '🇯🇵'},
    },
};

Or something like this:

export const parameters = {
  locale: "en_US",
  locales: {
    en_US: {title: "English", right: 'US'},
    en_GB: {title: "English", right: 'GB'},
    fr_FR: {title: "Français", right: 'FR'},
    ja_JP: {title: "日本語", right: 'JP'},
  },
};

Addons should instruct them to use whichever format your i18n implementation expects.
