Translation and Key Shortening Tool

A Node.js application that provides two utilities:

1. Translation Tool: Translate JSON strings to multiple languages using Google Translate API
2. Key Shortening Tool: Shorten JSON keys by removing vowels and converting to camelCase

Prerequisites

• Node.js (v12 or higher)
• Google Cloud Project with Translation API enabled
• Google Cloud Service Account with Translation API access

Installation

1. Clone the repository and install dependencies:

   npm install

2. Set up Google Cloud credentials:

   • Place your service account JSON file as credentials.json in the project root
   • Create a .env file with required variables:

     GOOGLE_CLOUD_PROJECT_ID=your-project-id
     TARGET_LANGUAGES=es,fr,de,pl
     

Usage

Translation Tool

Translate strings from English to multiple target languages:

npm run translate

Input: Place your English strings in input/en.json

{
  "Save and continue": "Save and continue",
  "Cancel": "Cancel"
}

Output: Translated files will be created in output/ directory (e.g., output/es.json, output/pl.json)

Key Shortening Tool

Shorten JSON keys by removing vowels while preserving readability:

npm run shorten [input-file] [output-file]

Example:

node shortenKeys.js input/en.json input/en_shortened.json

Configuration

• Target Languages: Set TARGET_LANGUAGES in your .env file (comma-separated ISO 639-1 codes)
• Vowel Pattern: Modify VOWEL_PATTERN in shortenKeys.js to customize shortening rules
