babel-plugin-react-intl：将字符串提取到单个文件

Question

目前在使用babel-plugin-react-intl时，使用'id'，'description'和'defaultMessage'创建每个组件的单独json。我需要的是只创建一个包含单个对象的json，其中所有'id'为'key'，'defaultMessage'为'value'

现状：

ComponentA.json

[
  {
    "id": "addEmoticonA",
    "description": "Add emoticon",
    "defaultMessage": "Insert Emoticon"
  },
  {
    "id": "addPhotoA",
    "description": "Add photo",
    "defaultMessage": "Insert photo"
  }
]

ComponentB.json

[
  {
    "id": "addEmoticonB",
    "description": "Add emoji",
    "defaultMessage": "Insert Emoji"
  },
  {
    "id": "addPhotoB",
    "description": "Add picture",
    "defaultMessage": "Insert picture"
  }
]

我需要翻译。

final.json

{
  "addEmoticonA": "Insert Emoticon",
  "addPhotoA": "Insert photo",
  "addEmoticonB": "Insert Emoji",
  "addPhotoB": "Insert picture"
}

有没有办法完成这项任务？可能是使用python脚本或任何东西。即从不同的json文件制作一个json文件。或者使用babel-plugin-react-intl直接生成一个json文件

Answer 1

有一个translations manager 可以做到这一点。

或者对于自定义选项，请参阅下面的

以下基于此script的脚本会查看由此创建的翻译消息 babel-plugin-react-intl并创建包含来自json格式的所有组件的所有消息的js文件。

import fs from 'fs'
import {
  sync as globSync
}
from 'glob'
import {
  sync as mkdirpSync
}
from 'mkdirp'
import * as i18n from '../lib/i18n'

const MESSAGES_PATTERN = './_translations/**/*.json'
const LANG_DIR         = './_translations/lang/'
  // Ensure output folder exists
mkdirpSync(LANG_DIR)

// Aggregates the default messages that were extracted from the example app's
// React components via the React Intl Babel plugin. An error will be thrown if
// there are messages in different components that use the same `id`. The result
// is a flat collection of `id: message` pairs for the app's default locale.
let defaultMessages = globSync(MESSAGES_PATTERN)
  .map(filename => fs.readFileSync(filename, 'utf8'))
  .map(file => JSON.parse(file))
  .reduce((collection, descriptors) => {
    descriptors.forEach(({
      id, defaultMessage, description
    }) => {
      if (collection.hasOwnProperty(id))
        throw new Error(`Duplicate message id: ${id}`)

      collection[id] = {
        defaultMessage, description
      }
    })
    return collection
  }, {})

// Sort keys by name
const messageKeys = Object.keys(defaultMessages)
messageKeys.sort()
defaultMessages = messageKeys.reduce((acc, key) => {
  acc[key] = defaultMessages[key]
  return acc
}, {})

// Build the JSON document for the available languages
i18n.en = messageKeys.reduce((acc, key) => {
  acc[key] = defaultMessages[key].defaultMessage
  return acc
}, {})
Object.keys(i18n).forEach(lang => {
  const langDoc = i18n[lang]
  const units = Object.keys(defaultMessages).map((id) => [id, defaultMessages[id]]).reduce((collection, [id]) => {
    collection[id] = langDoc[id] || '';
    return collection;
  }, {});
  fs.writeFileSync(`${LANG_DIR}${lang}.json`, JSON.stringify(units, null, 2))
})

您可以使用babel-plugin-react-intl-extractor将翻译汇总到一个文件中。此外，它还可以在每次更改邮件时提供自动重新编译的翻译文件。
