Vue3+Vue-i18n+I18N ALLY+VSCODE 自动翻译多国语言

ps: 效果图放前面,符合的往下看，不符合的出门右转，希望多多点赞评论支持。

• 三种语言模式，分别是中文、英文、日文
  
• 批量翻译
  
• 最后的结果
  

配置vue-i18n

1、下载安装vue-i18n，@9以上的版本。
2、创建对应文件夹

3、对应文件夹中代码如下

helper.ts

import type { LocaleType } from '@/types/i18n';
import { set } from 'lodash-es';export const loadLocalePool: LocaleType[] = [];export function setHtmlPageLang(locale: LocaleType) {document.querySelector('html')?.setAttribute('lang', locale);
}export function setLoadLocalePool(cb: (loadLocalePool: LocaleType[]) => void) {cb(loadLocalePool);
}
export function genMessage(langs: Record<string, Record<string, any>>, prefix = 'lang') {const obj: Recordable = {};Object.keys(langs).forEach((key) => {const langFileModule = langs[key].default;let fileName = key.replace(`./${prefix}/`, '').replace(/^\.\//, '');const lastIndex = fileName.lastIndexOf('.');fileName = fileName.substring(0, lastIndex);const keyList = fileName.split('/');const moduleName = keyList.shift();const objKey = keyList.join('.');if (moduleName) {if (objKey) {set(obj, moduleName, obj[moduleName] || {});set(obj[moduleName], objKey, langFileModule);} else {set(obj, moduleName, langFileModule || {});}}});return obj;
}

setupI18n.ts

import type { App } from 'vue';
import type { I18n, I18nOptions } from 'vue-i18n';
import { createI18n } from 'vue-i18n';
import { setHtmlPageLang, setLoadLocalePool } from './helper';
import { useLocaleStore } from '@/store/modules/locale'export let i18n: ReturnType<typeof createI18n>;
async function createI18nOptions(): Promise<I18nOptions> {const store = useLocaleStore()const locale = store.getLocalInfoconst defaultLocal = await import(`./lang/${locale}.ts`);const message = defaultLocal.default?.message ?? {};setHtmlPageLang(locale);setLoadLocalePool((loadLocalePool) => {loadLocalePool.push(locale);});return {legacy: false, //false:新版API locale,//当前语言fallbackLocale: 'zh_CN', //找不到语言环境，回滚到中文messages: {[locale]: message, //对应的语言环境具体值},availableLocales: ['zh_CN', 'en'],//包含的语言种类sync: true,  //是否从全局继承语言环境silentTranslationWarn: true, //true:关闭翻译警告missingWarn: false,//是否显示缺失翻译的警告信息silentFallbackWarn: true,//忽略回退警告};
}
export async function setupI18n(app: App) {const options = await createI18nOptions();i18n = createI18n(options) as I18n;app.use(i18n);
}

useLocale.ts

import type { LocaleType } from '@/types/i18n';
import { i18n } from './setupI18n';
import { unref, computed } from 'vue';
import { useLocaleStore } from '@/store/modules/locale'
import { loadLocalePool, setHtmlPageLang } from './helper';
interface LangModule {message: Recordable;dateLocale: Recordable;dateLocaleName: string;
}function setI18nLanguage(locale: LocaleType) {const store = useLocaleStore()if (i18n.mode === 'legacy') {i18n.global.locale = locale;} else {(i18n.global.locale as any).value = locale;}store.setLocaleInfo({ locale })setHtmlPageLang(locale);
}export function useLocale() {const store = useLocaleStore()const getLocale = computed(() => store.getLocalInfo);const getShowLocalePicker = computed(() => store.getShowPicker);const getAntdLocale = computed((): any => {return i18n.global.getLocaleMessage(store.getAntdLocale);});async function changeLocale(locale: LocaleType) {const globalI18n = i18n.global;const currentLocale = unref(globalI18n.locale);if (currentLocale === locale) {return locale;}if (loadLocalePool.includes(locale)) {setI18nLanguage(locale);return locale;}const langModule = ((await import(`./lang/${locale}.ts`)) as any).default as LangModule;if (!langModule) return;const { message } = langModule;globalI18n.setLocaleMessage(locale, message);loadLocalePool.push(locale);setI18nLanguage(locale);return locale;}return {getLocale,getShowLocalePicker,changeLocale,getAntdLocale,};
}

4、创建全局当前语言类型值，如果需要刷新保持，还应将值保存到localStorage中。

locale.ts

import { defineStore } from 'pinia';
import type { LocaleType } from '@/types/i18n'
type LocaleState = {localInfo: LocaleType,availableLocales: LocaleType[],showPicker: boolean,antdLocale: LocaleType
}
type SetLocalInfoOpt = {locale: LocaleType,
}
export const useLocaleStore = defineStore({id: 'app-locale',state: (): LocaleState => ({localInfo: 'zh_CN',showPicker: false,availableLocales: [],antdLocale: 'zh_CN'}),getters: {getLocalInfo(): LocaleType {return this.localInfo},getShowPicker(): boolean {return this.showPicker},getAntdLocale(): LocaleType{return this.antdLocale}},actions: {setLocaleInfo({ locale }: SetLocalInfoOpt) {this.localInfo = locale},}
})

5、lang文件夹下创建对应翻译的入口en.ts\ja.ts\zh_CH.ts

import { genMessage } from '../helper';
import antdLocale from 'ant-design-vue/es/locale/en_US';//更改对应的类型const modules:Record<string, Record<string, any>> = import.meta.globEager('./en/**/*.json'); //更改对应的类型
export default {message: {...genMessage(modules, 'en'),//更改对应的类型antdLocale,},dateLocale: null,dateLocaleName: 'en',//更改对应的类型
};

5、main.ts中引入

import { setupI18n } from '@/locales/setupI18n';
await setupI18n(app);

6、页面中引入

<template><p><a-button @click="onChange('zh_CN')">中文</a-button><a-button @click="onChange('en')">英文</a-button><a-button @click="onChange('ja')">日文</a-button></p><div>{{ t('common.a') }}</div><div>{{ t('common.b') }}</div><div>{{ t('common.c') }}</div><div>{{ t('common.d') }}</div><div>{{ t('common.e') }}</div>
</template>
<script lang="ts">
import { defineComponent } from 'vue'
import { useI18n } from '@/hooks/web/useI18n';
import type { LocaleType } from '@/types/i18n';
import { useLocale } from '@/locales/useLocale';
export default defineComponent({setup() {const { changeLocale } = useLocale();const { t } = useI18n();async function onChange(local: LocaleType) {await changeLocale(local as LocaleType);}return {t,onChange}}
})
</script>
<style lang="less"></style>

至此，页面上的语言切换可以了。接下来是如何自动翻译

VSCODE插件I18n Ally

1、插件市场下载

2、在.vscode下新建settings.json文件

3、在配置文件中新增关于i18n的设置。

{"i18n-ally.localesPaths": ["src/locales/lang"], // 翻译文件路径 (自动生成) 相对于项目根目录的语言环境目录路径"i18n-ally.pathMatcher": "{locale}/{namespaces}.{ext}","i18n-ally.enabledParsers": ["json"],"i18n-ally.sourceLanguage": "zh-CN","i18n-ally.displayLanguage": "zh-CN","i18n-ally.enabledFrameworks": ["vue","react"],// 如下须要手动配置"i18n-ally.keystyle": "nested", // 翻译路径格式 (翻译后变量格式 nested：嵌套式  flat:扁平式)"i18n-ally.sortKeys": true,"i18n-ally.namespace": true,"i18n-ally.translate.engines": ["google","deepl"], // 翻译器"i18n-ally.extract.keygenStyle": "camelCase", // 翻译字段命名样式采用驼峰
}

备注“i18n-ally.localesPaths”这个是你翻译文件的路径、“i18n-ally.translate.engines”翻译器，需要科学上网(fq)。

4、配置成功后，鼠标移动上去会显示当前翻译结果，失败的可以关闭编译器重启。

5、批量翻译，点击编译器左下角翻译的图标，然后再翻译进度中找到，未翻译的语言。空值右边对应有个地球图标。单击翻译即可。

有些人写的翻译是json文件有的是TS文件，注意配置的时候和lang文件夹下面的入口文件
不要写错了。
写在最后，有问题可评论，可私聊。欢迎讨论。
