You can choose any configuration method in cosmiconfig format

• i18n property in package.json
• .i18nrc file in JSON or YAML format
• .i18nrc.json, .i18nrc.yaml, .i18nrc.yml, .i18nrc.js, .i18nrc.cjs
• defineConfig provides a secure definition method that can be imported from @lobehub/i18n-cli

This project provides some additional configuration items set with environment variables:

const { defineConfig } = require('@lobehub/i18n-cli');

module.exports = defineConfig({
  entry: 'locales/en_US.json',
  entryLocale: 'en_US',
  output: 'locales',
  outputLocales: ['zh_CN', 'ja_JP'],
});

{
  "entry": "locales/en_US.json",
  "entryLocale": "en_US",
  "output": "locales",
  "outputLocales": ["zh_CN", "ja_JP"]
}

{
  "...": "...",
  "i18n": {
    "entry": "locales/en_US.json",
    "entryLocale": "en_US",
    "output": "locales",
    "outputLocales": ["zh_CN", "ja_JP"]
  }
}

There are two types of file structures supported: flat and tree.

A flat structure means that all translations for different languages are stored in a single file, as shown below:

- locales
  - en_US.json
  - ja_JP.json
  - zh_CN.json
  - ...

{
  "entry": "locales/en.json",
  "entryLocale": "en_US",
  "output": "locales",
  "outputLocales": ["zh_CN", "ja_JP"]
}

A tree structure means that the translations for each language are stored in separate language folders, as shown below:

- locales
  - en_US
    - common.json
    - header.json
    - subfolder
      - ...
  - ja_JP
    - common.json
    - header.json
    - subfolder
      - ...
  - zh_CN
    - common.json
    - header.json
    - subfolder
      - ...

{
  "entry": "locales/en_US",
  "entryLocale": "en_US",
  "output": "locales",
  "outputLocales": ["zh_CN", "ja_JP"]
}

Use the lobe-i18n command to generate i18n files automatically:

$ lobe-i18n

By default, the translated file names are generated as .{locale}.md. You can customize the output file extensions with outputExtensions.

module.exports = {
  markdown: {
    entry: ['./README.zh-CN.md', './docs/**/*.zh-CN.md'],
    entryLocale: 'zh-CN',
    entryExtension: '.zh-CN.md',
    outputLocales: ['en-US', 'ja-JP'],
    outputExtensions: (locale, { getDefaultExtension }) => {
      if (locale === 'en-US') return '.md';
      return getDefaultExtension(locale);
    },
  },
};

outputExtensions supports the following props:

interface OutputExtensionsProps {
  /**
   * @description The locale of the translated file to output
   */
  locale: string;
  config: {
    /**
     * @description The content of the translated file to input
     */
    fileContent: string;
    /**
     * @description The path of the translated file to input
     */
    filePath: string;
    /**
     * @description The default method for generating extensions
     */
    getDefaultExtension: (locale: string) => string;
  };
}

mode is used to specify the translation mode, which supports two modes and custom generation modes.

• string - Translates the complete markdown content.
• mdast - Parses the text with mdast structure and translates the text value content. To translate code blocks, you need to enable translateCode.

The translated files will be generated in the same directory as the entry file, with the corresponding language suffix added to the extension:

- README.md
- README.zh-CN.md
	- docs
		- usage.md
		- usage.zh-CN.md
		- subfolder
            - ...

Use the lobe-i18n md command to automate the generation of i18n files:

$ lobe-i18n md
