Multilingual Settings

Multilingual settings are required during the development of control panels. tuya-panel-kit provides the built-in internationalization module to configure multilingual settings.

Configure multilingual settings

Define the following languages in the file src/i18n/strings.{js,ts}.

// Both the `en` and `zh` fields must be defined.
export default {
  en: {
    hello: 'Hello',
  },
  zh: {
    hello: '你好',
  }
};

Generate and export multilingual settings

Export the instance from the file src/i18n/index.{js,ts}.

import { I18N } from 'tuya-panel-kit';
import Strings from './strings';

export default new I18N(Strings);

Use multilingual settings

The multilingual settings apply to any multilingual scenario.

import Strings from '../i18n';

const localizedText = Strings.getLang('hello');

console.log(localizedText);

Define the rules to set multilingual keys

For more information about the use of the bitmap type, see How to use of bitmap.

export default {
  en: {
    dsc_edit: 'Edit', // Basic multilingual settings start with `dsc_` and define the semantics.
    dsc_countdown_on: 'Turn on after {0}',
    dp_switch: 'Switch', // The multilingual settings of data points (DPs) are defined in the format of `dp_${dpCode}`.
    dp_switch_on: 'Switch is On', // The multilingual settings of Boolean DP status are defined in the format of `dp_${dpCode}_${'on' || 'off'}`.
    dp_mode_smart: 'Smart Mode', // The multilingual settings of enum DP status are defined in the format of `dp_${dpCode}_${enumValue}`.
    dp_fault_0: 'Binary first bit is faulty', // The multilingual settings of bitmap DP status are defined in the format of `dp_${dpCode}_${bit}`.
    dp_fault_1: 'Binary second bit is faulty',
  },
  zh: {
    dsc_edit: '编辑', //  基础多语言以 dsc_ 开头并命名语义化即可
    dsc_countdown_on: '设备将在{0}后开启',
    dp_switch: '开关', // 功能点（DP）相关多语言需按照 `dp_${dpCode}` 进行命名
    dp_switch_on: '开关开', // 布尔类型功能点状态相关多语言需按照 `dp_${dpCode}_${'on' || 'off'}` 进行命名
    dp_mode_smart: '智能模式', // 枚举类型功能点状态相关多语言需按照 `dp_${dpCode}_${enumValue}` 进行命名
    dp_fault_0: '第一位故障', // Bitmap 类型功能点状态相关多语言需按照 `dp_${dpCode}_${bit}` 进行命名
    dp_fault_1: '第二位故障',
  }
};

Multilingual setting API methods

The following examples come from the preceding section of multilingual key definition rules.

getLang

/**
 * @desc Returns basic multilingual settings.
 * @param {String} key - The multilingual key.
 * @returns {String} The multilingual value.
 */
// en: Edit; zh: 编辑; If not found: i18n@dsc_edit;
Strings.getLang('dsc_edit');

getDpLang

/**
 * @desc Returns the DP multilingual setting.
 * @param {String} dpCode - The DP name.
 * @param {String|Number} value - The DP value.
 * @returns {String} The multilingual value.
 */
// en: Smart Mode; zh: 智能模式; If not found: dp_mode_smart;
Strings.getDpLang('mode', 'smart');

formatValue

/**
 * @desc Concatenate multilingual values.
 * @param {String} key - The multilingual key.
 * @param {...String|Number} values - One or more matching values to be replaced.
 * @returns {String} The multilingual value.
 */
// en: Turn on after 1 minute; zh: 设备将在1分钟后开启; If not found: null character;
Strings.formatValue('countdown_on', '1分钟');
