To install Lobe i18n, run the following command:

npm install -g @lobehub/i18n-cli

[!IMPORTANT]
Please make sure you have Node.js version >= 18.

To initialize the Lobe i18n configuration, run the following command:

$ lobe-i18n -o # or use the full flag --option

[!IMPORTANT]
To use AI auto-generation, you need to fill in the OpenAI Token in the settings.

# Translate Locale files
$ lobe-i18n # or $ lobe-i18n locale

# Translate Markdown files
$ lobe-i18n md

# Run i18n translation and markdown translation simultaneously
$ lobe-i18n --with-md

# Specify the configuration file
$ lobe-i18n -c './custom-config.js' # or use the full flag --config

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

[!TIP]

This project provides a secure definition method defineConfig 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
  - ...

[!TIP]

The flat structure requires configuring the entry property in the configuration file to the corresponding JSON file Example

{
  "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
      - ...

[!TIP]

The tree structure requires configuring the entry property in the configuration file to the corresponding folder Example

{
  "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.

[!NOTE]

In the example below, the entry file extension is .zh-CN.md, but we want the output file extension for the en-US translation to be .md, while other languages keep the default extensions.

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.

[!WARNING]

In mdast mode, the content to be translated will be reduced to a minimum, removing most markdown syntax structures and links. This mode can greatly reduce token consumption, but it may result in inaccurate translation results.

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
            - ...

[!TIP]

Example

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

$ lobe-i18n md

You can use Github Codespaces for online development:

Alternatively, you can clone the repository and run the following command for local development:

$ git clone https://github.com/lobehub/lobe-cli-toolbox.git
$ cd lobe-cli-toolbox
$ bun install
$ cd packages/lobe-i18n
$ bun dev
