Intlayer CLI

Install Package

Install the necessary packages using npm:

npm install intlayer-cli -g

If intlayer package is already installed, the cli is automatically installed. You can skip this step.

intlayer-cli package

intlayer-cli package intend to transpile your intlayer declarations into dictionaries.

This package will transpile all intlayer files, such as src/**/*.content.{ts|js|mjs|cjs|json}. See how to declare your Intlayer declaration files.

To interpret intlayer dictionaries you can interpreters, such as react-intlayer, or next-intlayer

Configuration File Support

Intlayer accepts multiple configuration file formats:

• intlayer.config.ts
• intlayer.config.js
• intlayer.config.json
• intlayer.config.cjs
• intlayer.config.mjs
• .intlayerrc

To see how to configure available locales, or other parameters, refer to the configuration documentation here.

Run intlayer commands

Check CLI version

npx intlayer --versionnpx intlayer version

Both commands print the installed Intlayer CLI version.

Build dictionaries

To build your dictionaries, you can run the commands:

npx intlayer build

or in watch mode

npx intlayer build --watch

This command will find your declaration content files as default as ./src/**/*.content.{ts|js|mjs|cjs|json|tsx|jsx}. And build the dictionaries in the .intlayer directory.

Aliases:

• npx intlayer dictionaries build
• npx intlayer dictionary build
• npx intlayer dic build

Arguments:

• --base-dir: Specify the base directory for the project. To retrieve the intlayer configuration, the command will look for the intlayer.config.{ts,js,json,cjs,mjs} file in the base directory.

  Example: npx intlayer build --base-dir ./src

• --env: Specify the environment (e.g., development, production). Useful in the case you use environment variables in your intlayer configuration file.

  Example: npx intlayer build --env production

• --env-file: Provide a custom environment file to load variables from. Useful in the case you use environment variables in your intlayer configuration file.

  Example: npx intlayer build --env-file .env.production.local

• --with: Start command in parallel with the build.

  Example: npx intlayer build --with "next dev --turbopack"

• --skip-prepare: Skip the prepare step.

  Example: npx intlayer build --skip-prepare

Watch dictionaries

npx intlayer watch

This command will watch for changes in your content declaration files and build the dictionaries in the .intlayer directory. This command is the equivalent of npx intlayer build --watch --skip-prepare.

Aliases:

• npx intlayer dictionaries watch
• npx intlayer dictionary watch
• npx intlayer dic watch

Arguments:

• --with: Start command in parallel with the watch.

  Example: npx intlayer watch --with "next dev --turbopack"

Push dictionaries

npx intlayer dictionary push

If intlayer editor is installed, you can also push dictionaries to the editor. This command will allow to make the dictionaries available to the editor. By this way, you can share your dictionaries with your team and edit your content without editing the code of your application.

Aliases:

• npx intlayer dictionaries push
• npx intlayer dictionary push
• npx intlayer dic push

Arguments:

Dictionary options:

• -d, --dictionaries: ids of the dictionaries to pull. If not specified, all dictionaries will be pushed.

  Example: npx intlayer dictionary push -d my-dictionary-id my-other-dictionary-id

Configuration options:

• --base-dir: Specify the base directory for the project. To retrieve the intlayer configuration, the command will look for the intlayer.config.{ts,js,json,cjs,mjs} file in the base directory.

  Example: npx intlayer dictionary push --env-file .env.production.local

Environment variables options:

• --env: Specify the environment (e.g., development, production). Useful in the case you use environment variables in your intlayer configuration file.

This command will scan all your content declaration files and display:

• A detailed list of missing translations with their keys, missing locales, and file paths
• Summary statistics including total missing locales and missing required locales
• Color-coded output for easy identification of issues

The output helps you quickly identify which translations need to be completed to ensure your application works properly across all configured locales.

List content declaration files

This command displays all content declaration files in your project, showing their dictionary keys and file paths. It's useful for getting an overview of all your content files and verifying that they are properly discovered by Intlayer.

Example:

npx intlayer content list

This command will output:

• A formatted list of all content declaration files with their keys and relative file paths
• The total count of content declaration files found

The output helps you verify that all your content files are properly configured and discoverable by the Intlayer system.

Manage Configuration

Document Management

The doc commands provide tools for managing and translating documentation files across multiple locales.

Translate Document

The doc translate command automatically translates documentation files from a base locale to target locales using AI translation services.

npx intlayer doc translate

Arguments:

File list options:

• --doc-pattern [docPattern...]: Glob patterns to match documentation files to translate.

  Example: npx intlayer doc translate --doc-pattern "docs/**/*.md" "src/**/*.mdx"

  • Can be a relative time in ms 1 * 60 * 60 * 1000 (1 hour)
  • This option check update time of the file using the fs.stat method. So it could be impacted by Git or other tools that modify the file.

  Example: npx intlayer doc translate --skip-if-modified-before "2025-12-05"

• --skip-if-modified-after [skipIfModifiedAfter]: Skip the file if it has been modified within the given time.

  • Can be an absolute time as "2025-12-05" (string or Date)
  • Can be a relative time in ms 1 * 60 * 60 * 1000 (1 hour)
  • This option check update time of the file using the fs.stat method. So it could be impacted by Git or other tools that modify the file.

  Example: npx intlayer doc translate --skip-if-modified-after "2025-12-05"

Entry output options:

• --locales [locales...]: Target locales to translate documentation to.

  Example: npx intlayer doc translate --locales fr es de

• --base-locale [baseLocale]: Source locale to translate from.

  Example: npx intlayer doc translate --base-locale en

File processing options:

• --nb-simultaneous-file-processed [nbSimultaneousFileProcessed]: Number of files to process simultaneously for translation.

  Example: npx intlayer doc translate --nb-simultaneous-file-processed 5

AI options:

• --model [model]: The AI model to use for translation (e.g., gpt-3.5-turbo).
• --provider [provider]: The AI provider to use for translation.
• --temperature [temperature]: Temperature setting for the AI model.

  • Can be an absolute time as "2025-12-05" (string or Date)
  • Can be a relative time in ms 1 * 60 * 60 * 1000 (1 hour)
  • This option check update time of the file using the fs.stat method. So it could be impacted by Git or other tools that modify the file.

  Example: npx intlayer doc translate --custom-instructions "Avoid translating urls, and keep the markdown format"

  Example: npx intlayer doc translate --custom-instructions "$(cat ./instructions.md)"

Git options:

• --git-diff: Only run on dictionaries that includes changes from base (default origin/main) to current branch (default: HEAD).
• --git-diff-base: Specify the base reference for git diff (default origin/main).
• --git-diff-current: Specify the current reference for git diff (default: HEAD).
• --uncommitted: Include uncommitted changes.

  Example: npx intlayer doc translate --git-diff --git-diff-base origin/main --git-diff-current HEAD

  Example: npx intlayer doc translate --uncommitted --unpushed --untracked

Note that the output file path will be determined by replacing the following patterns

• /{{baseLocale}}/ by /{{locale}}/ (Unix)
• {{baseLocale}}` by {{locale}}` (Windows)
• _{{baseLocale}}. by _{{locale}}.
• {{baseLocale}}_ by {{locale}}_
• .{{baseLocaleName}}. by .{{localeName}}.

If the pattern is not found, the output file will add the .{{locale}} at the extensions of the file. ./my/file.md will be translated to ./my/file.fr.md for the French locale.

Review Document

The doc review command analyzes documentation files for quality, consistency, and completeness across different locales.

npx intlayer doc review

It can be used to review files that are already translated, and to check if the translation is correct.

For most use cases,

• prefer using the doc translate when the translated version of this file is not available.
• prefer using the doc review when the translated version of this file already exists.

Note that the review process consumes more entry tokens than the translate process to review the same file entirely. However, the review process will optimize the chunks to review, and will skip the parts that are not changed.

Arguments:

The doc review command accepts the same arguments as doc translate, allowing you to review specific documentation files and apply quality checks.

If you activated one of the git options, the command will only review the part of the files that getting changed. The script will process by chunking the file and review each chunk. If there is no changes in the chunk, the script will skip it to speed up the review process and limit the AI Provider API cost.

Use intlayer commands in your package.json

"scripts": {  "intlayer:build": "npx intlayer build",  "intlayer:watch": "npx intlayer build --watch",  "intlayer:push": "npx intlayer push",  "intlayer:pull": "npx intlayer pull",  "intlayer:fill": "npx intlayer fill",  "intlayer:list": "npx intlayer content list",  "intlayer:test": "npx intlayer content test",  "intlayer:doc:translate": "npx intlayer doc translate",  "intlayer:doc:review": "npx intlayer doc review"}

Editor commands

The editor command rewrap the intlayer-editor commands.

To be able to use the editor command, the intlayer-editor package must be installed. (See Intlayer Visual Editor)

"scripts": {  "intlayer:editor:start": "npx intlayer editor start --with 'next dev --turbopack'"}

CLI SDK

The CLI SDK is a library that allows you to use the Intlayer CLI in your own code.

npm install @intlayer/cli --save-dev

Example of usage:

import {  push,  pull,  fill,  build,  listContentDeclaration,  testMissingTranslations,  docTranslate,  docReview,} from "@intlayer/cli";push();// ...pull();// ...fill();// ...build();// ...listContentDeclaration();// ...testMissingTranslations();// ...docTranslate();// ...docReview();// ...

Debug intlayer command

1. Ensure you're using the latest version

Run:

npx intlayer --version                  # current locale intlayer versionnpx intlayer@latest --version           # current latest intlayer version

2. Check if the command is registered

You can check with:

npx intlayer --help                     # Shows the list of available commands and usage informationnpx intlayer dictionary build --help    # Shows the list of available options for a command

3. Restart your terminal

Sometimes a terminal restart is needed to recognize new commands.
