Table of contents

Installation

使用纱线:

yarn add @ackee/jerome

使用 npm:

npm i -s @ackee/jerome

Usage

所有部分都是独立的,但最好一起工作。 不要忘记,为了正确使用选择器,您的 reducer 必须使用 translate 键存储(如示例所示)。

Used APIs

杰罗姆使用 react-intl@3 依赖于一些本机浏览器 API 因此,如果您打算将组件用于复数或相对时间格式,请确保您的最小支持浏览器实现这些 API 或使用 polyfill,如所述波纹管

对于 polyfilling 复数,使用 intl-pluralrules 包。

if (!Intl.PluralRules) {
  require('intl-pluralrules');
}

对于填充复数,请使用 intl-relativetimeformat 包。

if (!Intl.RelativeTimeFormat) {
  require('@formatjs/intl-relativetimeformat/polyfill');
  require('@formatjs/intl-relativetimeformat/dist/locale-data/de'); // Add locale data for de
}

API

Components

Translatable

  • It wraps children with IntlProvider from react-intl. The IntlProvider receives current locale from redux store.
  • It dispatches SET_INTL action everytime the locale changes. This is required to make [getIntl] saga work. See createIntlContext for more info.

⚠️
为了让它顺利运行,你必须只安装一次 react-intl! 所以要确保你的依赖结构是扁平的。

import { Translatable } from '@ackee/jerome';

const messages = {
    cs: {
        hello: 'Dobry den',
        ...
    },
    en: {
        hello: 'Hello',
        ...
    },
};

export function Localizations({ children }) {
    return <Translatable intlMessages={messages}>{children}</Translatable>
}

HOC

重要 要使 HOC 正常工作,您必须只安装一次 react-intl! 所以要确保你的依赖结构是扁平的。

[Deprecated]translatableFactory(intlLocaleData): (ContentComponent) => TranslatableContentComponent

它提供 reac-intl 本地化上下文,因此您首先必须向将返回实际 HOC 的工厂提供本地化消息。

intlLocaleData - 包含由语言环境名称键入的消息的对象,例如。

const messages = {
    cs: {
        hello: 'Dobry den',
        ...
    },
    en: {
        hello: 'Hello',
        ...
    },
}

工厂返回接收 ContentComponent 的函数,并用 IntlProvider 包装返回它从 store.translate.locale 存储路径。

示例

import { FormattedMessage, addLocaleData } from 'react-intl';
import { translatableFactory } from '@ackee/jerome';

const ContentComponent = () => (
    <div id="app">
        <h1><FormattedMessage id="hello" /></h1>
        <h2><FormattedMessage id="bye.instant" /></h2>
        <h3><FormattedMessage id="bye.forever" /></h3>
    </div>
);

const messages = {
    cs: {
        hello: 'Cau',
        'bye.instant': 'Nashledanou',
        'bye.forever': 'Sbohem',
    },
    en: {
        hello: 'Hello',
        'bye.instant': 'See you later',
        'bye.forever': 'Goodbye',
    },
};

const store = createStore((state = initialState) => ({
    translate: { locale: 'cs' },
}));

TranslatableComponent = translatableFactory(messages)(ContentComponent);

ReactDOM.render(<TranslatableComponent store={store} />, document.getElementById('app'));

translatableFactory(intlLocaleData, antdLocaleData): (ContentComponent) => TranslatableContentComponent

translatableFactory 的重载用于Ant design组件库。 它通过添加 antd 本地化上下文扩展了标准 translatableFactory,但您必须提供 antLocaleData 作为工厂的第二个参数。

intlLocaleData - 以语言环境名称为键的 antd 语言环境对象。 例如。

import cs_CZ from 'antd/lib/locale-provider/cs_CZ';
import en_US from 'antd/lib/locale-provider/en_US';

const messages = {
    cs: cs_CZ,
    en: en_US,
}

用法和translatableFactory几乎一样,你只需要从@ackee/jerome/antd导入它 而不是 @ackee/jerome

import { FormattedMessage, addLocaleData } from 'react-intl';

import { Pagination } from 'antd';
import cs_CZ from 'antd/lib/locale-provider/cs_CZ';
import en_US from 'antd/lib/locale-provider/en_US';

import { translatableFactory } from '@ackee/jerome/antd'; // notice the import path

const ContentComponent = () => (
    <div id="app">
        <h1><FormattedMessage id="hello" /></h1>
        <Pagination defaultCurrent={1} total={50} showSizeChanger />
    </div>
);

const messages = {
    cs: {
        hello: 'Cau',
    },
    en: {
        hello: 'Hello',
    },
};

const antdMessages = {
    cs: cs_CZ,
    en: en_US,
}

const store = createStore((state = initialState) => ({
    translate: { locale: 'cs' },
}));

// provide antd messages as a second argument
TranslatableComponent = translatableWithAntdFactory(messages, antdMessages)(ContentComponent);

ReactDOM.render(<TranslatableComponent store={store} />, document.getElementById('app'));

Actions

setLocale(locale: string)

示例

import { setLocale } from '@ackee/jerome';

dispatch(setLocale('cs'));

getLocale

示例

import { getLocale } from '@ackee/jerome';

dispatch(getLocale());

Action types

import { actionTypes } from '@ackee/jerome'

Reducer

Reducer 实际上是reducer 工厂,因为您必须首先提供默认语言环境。

reducer(locale: string): TranslateReducer

示例

import { reducer as translateFactory } from '@ackee/jerome';

const translate = translateFactory('cs');

const appReducers = combineReducers({
    translate,
    ...
});

Selectors

translateSelector(state: State): { locale: string }

选择商店的翻译 部分。

示例

import { translateSelector } from '@ackee/jerome';

translateSelector(state); // { locale: 'cs' }

Sagas

saga()

传奇有两个目的,都与处理语言环境的持久存储有关。

  • It saves locale on every SET_LOCALE action into the persistent storage.
  • It loads locale from persistent storage when app load and set it up.

示例

import { saga as localization } from '@ackee/jerome';

const rootSaga = function* () {
    yield all([
        localization(), // plug it into root saga
        ...
    ]);
};

function configureStore(initialState) {
    const sagaMiddleware = createSagaMiddleware();
    const middlewares = [sagaMiddleware];

    const middleware = applyMiddleware(...middlewares);

    const store = createStore(reducer, initialState, enhancer);
    sagaMiddleware.run(rootSaga);

    return store;
}

createIntlContext

createIntlContext 是一个辅助函数,用于创建 getIntl​​ saga 使用的特定上下文形状。 由于 redux-saga 上下文的限制,此上下文必须由该库的用户在应用程序的最顶层传奇中设置:

import { setContext, all } from 'redux-saga/effects';
import { createIntlContext } from '@ackee/jerome';

function * rootSaga() {
    yield setContext(createIntlContext());

    yield all([
        .... sagas using getIntl()
    ])
}

sagaMiddleware.run(rootSaga);

如果没有设置上下文,getIntl​​ saga 将返回 null 即使库的其余部分被正确使用。

getIntl(): IntlShape

getIntl​​ saga 返回一个与 intlShape< 完全对应的 intl 对象/代码>。 saga 依赖于 createIntlContext

Example

import { getIntl } from '@ackee/jerome';

function* mySaga() {
    const intl = yield getIntl();

    const translatedMessage = intl.formatMessage({
        id: 'hello'
    });
}

Utilities

saveLocale(locale: string)

的正确使用,用于区域设置的持久存储。

示例

import { saveLocale } from '@ackee/jerome';

saveLocale('cs');

loadLocale(): string

用于从持久存储中获取语言环境设置。

示例

import { loadLocale } from '@ackee/jerome';

loadLocale(); // 'cs'

localStorageHandlers

涵盖了上述两个实用程序。

例子

import { localStorageHandlers } from '@ackee/jerome';

localStorageHandlers.saveLocale('en');
localStorageHandlers.loadLocale(); // 'en'

Jerome

Localization module useful mainly for frontend development in Ackee.

Name of package refers to Saint Jerome the patron of all translators.

Table of contents

Installation

Using yarn:

yarn add @ackee/jerome

Using npm:

npm i -s @ackee/jerome

Usage

All parts are independent, but best works all together. Don't forget that for correct usage of selectors your reducer have to be stored with translate key (as in example).

Used APIs

Jerome uses react-intl@3 which relies on some native browser APIs so if you're going to use components for plurals or relative time format, be sure that your minimal supported browsers implement those APIs or use polyfills as described bellow

For polyfilling plurals, use intl-pluralrules package.

if (!Intl.PluralRules) {
  require('intl-pluralrules');
}

For polyfilling plurals, use intl-relativetimeformat package.

if (!Intl.RelativeTimeFormat) {
  require('@formatjs/intl-relativetimeformat/polyfill');
  require('@formatjs/intl-relativetimeformat/dist/locale-data/de'); // Add locale data for de
}

API

Components

Translatable

  • It wraps children with IntlProvider from react-intl. The IntlProvider receives current locale from redux store.
  • It dispatches SET_INTL action everytime the locale changes. This is required to make [getIntl] saga work. See createIntlContext for more info.

⚠️
To make it work smoothly, you must have react-intl installed just once! So be sure your dependencies structure is flat.

import { Translatable } from '@ackee/jerome';

const messages = {
    cs: {
        hello: 'Dobry den',
        ...
    },
    en: {
        hello: 'Hello',
        ...
    },
};

export function Localizations({ children }) {
    return <Translatable intlMessages={messages}>{children}</Translatable>
}

HOC

Important To make HOCs works properly, you must have react-intl installed just once! So be sure your dependencies structure is flat.

[Deprecated]translatableFactory(intlLocaleData): (ContentComponent) => TranslatableContentComponent

It provides reac-intl localization context, so you first have to provide localization messages to the factory that will return the actual HOC.

intlLocaleData - object with messages keyed by locale name, eg.

const messages = {
    cs: {
        hello: 'Dobry den',
        ...
    },
    en: {
        hello: 'Hello',
        ...
    },
}

The factory returns function that receives ContentComponent and return it wrapped with IntlProvider which receives locale from the store.translate.locale store path.

Example

import { FormattedMessage, addLocaleData } from 'react-intl';
import { translatableFactory } from '@ackee/jerome';

const ContentComponent = () => (
    <div id="app">
        <h1><FormattedMessage id="hello" /></h1>
        <h2><FormattedMessage id="bye.instant" /></h2>
        <h3><FormattedMessage id="bye.forever" /></h3>
    </div>
);

const messages = {
    cs: {
        hello: 'Cau',
        'bye.instant': 'Nashledanou',
        'bye.forever': 'Sbohem',
    },
    en: {
        hello: 'Hello',
        'bye.instant': 'See you later',
        'bye.forever': 'Goodbye',
    },
};

const store = createStore((state = initialState) => ({
    translate: { locale: 'cs' },
}));

TranslatableComponent = translatableFactory(messages)(ContentComponent);

ReactDOM.render(<TranslatableComponent store={store} />, document.getElementById('app'));

translatableFactory(intlLocaleData, antdLocaleData): (ContentComponent) => TranslatableContentComponent

There is an overload of translatableFactory for usage with Ant design components library. It extends standard translatableFactory with adding antd localization context, but you have to provide the antLocaleData as a second argument to the factory.

intlLocaleData - object with antd locales keyed by locale name. eg.

import cs_CZ from 'antd/lib/locale-provider/cs_CZ';
import en_US from 'antd/lib/locale-provider/en_US';

const messages = {
    cs: cs_CZ,
    en: en_US,
}

Usage is almost same as for the translatableFactory, you only need to import it from @ackee/jerome/antd instead of @ackee/jerome.

import { FormattedMessage, addLocaleData } from 'react-intl';

import { Pagination } from 'antd';
import cs_CZ from 'antd/lib/locale-provider/cs_CZ';
import en_US from 'antd/lib/locale-provider/en_US';

import { translatableFactory } from '@ackee/jerome/antd'; // notice the import path

const ContentComponent = () => (
    <div id="app">
        <h1><FormattedMessage id="hello" /></h1>
        <Pagination defaultCurrent={1} total={50} showSizeChanger />
    </div>
);

const messages = {
    cs: {
        hello: 'Cau',
    },
    en: {
        hello: 'Hello',
    },
};

const antdMessages = {
    cs: cs_CZ,
    en: en_US,
}

const store = createStore((state = initialState) => ({
    translate: { locale: 'cs' },
}));

// provide antd messages as a second argument
TranslatableComponent = translatableWithAntdFactory(messages, antdMessages)(ContentComponent);

ReactDOM.render(<TranslatableComponent store={store} />, document.getElementById('app'));

Actions

setLocale(locale: string)

Example

import { setLocale } from '@ackee/jerome';

dispatch(setLocale('cs'));

getLocale

Example

import { getLocale } from '@ackee/jerome';

dispatch(getLocale());

Action types

import { actionTypes } from '@ackee/jerome'

Reducer

Reducer is actually reducer factory since you must provide default locale first.

reducer(locale: string): TranslateReducer

Example

import { reducer as translateFactory } from '@ackee/jerome';

const translate = translateFactory('cs');

const appReducers = combineReducers({
    translate,
    ...
});

Selectors

translateSelector(state: State): { locale: string }

Select translate part of store.

Example

import { translateSelector } from '@ackee/jerome';

translateSelector(state); // { locale: 'cs' }

Sagas

saga()

The saga has two purposes, both related to handling persistent storing of locale.

  • It saves locale on every SET_LOCALE action into the persistent storage.
  • It loads locale from persistent storage when app load and set it up.

Example

import { saga as localization } from '@ackee/jerome';

const rootSaga = function* () {
    yield all([
        localization(), // plug it into root saga
        ...
    ]);
};

function configureStore(initialState) {
    const sagaMiddleware = createSagaMiddleware();
    const middlewares = [sagaMiddleware];

    const middleware = applyMiddleware(...middlewares);

    const store = createStore(reducer, initialState, enhancer);
    sagaMiddleware.run(rootSaga);

    return store;
}

createIntlContext

The createIntlContext is a helper function to create a specific context shape used by getIntl saga. Due to limitations of the redux-saga context, this context has to be set by a user of this library in the most top saga of the application:

import { setContext, all } from 'redux-saga/effects';
import { createIntlContext } from '@ackee/jerome';

function * rootSaga() {
    yield setContext(createIntlContext());

    yield all([
        .... sagas using getIntl()
    ])
}

sagaMiddleware.run(rootSaga);

Without having the context set, getIntl saga would return null even though the rest of the library is used properly.

getIntl(): IntlShape

The getIntl saga returns an intl object that exactly corresponds to the intlShape. The saga relies on proper usage of createIntlContext

Example

import { getIntl } from '@ackee/jerome';

function* mySaga() {
    const intl = yield getIntl();

    const translatedMessage = intl.formatMessage({
        id: 'hello'
    });
}

Utilities

saveLocale(locale: string)

Used for persistent store of locale setting.

Example

import { saveLocale } from '@ackee/jerome';

saveLocale('cs');

loadLocale(): string

Used for getting locale setting from persistent storage.

Example

import { loadLocale } from '@ackee/jerome';

loadLocale(); // 'cs'

localStorageHandlers

Covers both utilities mentioned above.

Example

import { localStorageHandlers } from '@ackee/jerome';

localStorageHandlers.saveLocale('en');
localStorageHandlers.loadLocale(); // 'en'
