Nodejs script for updating Angular i18n json files in CLI

updateTranslations.js

// Usage example:
// node updateTranslations.js COMMON are_you_sure "Are you sure?" az,en,ru
// or
// node updateTranslations.js COMMON are_you_sure "Are you sure?" // this will update all three languages. it's the same as above

const fs = require("fs");
const path = require("path");

// Get command-line arguments
const args = process.argv.slice(2);

// Check if there are enough arguments
if (args.length < 3) {
  console.error('\x1b[31mError:\x1b[0m Usage: node updateTranslations.js <category> <key> <value> languages');
  process.exit(1);
}

// Extract arguments
const category = args[0];
const key = args[1];
const value = args[2];
const languages = args[3] ? args[3].split(",") : ["az", "en", "ru"];

// Define the directory where your translation files are located
const translationDir = path.join(__dirname, "src", "assets", "i18n");

// Loop through each language file and update the translations
languages.forEach((language) => {
  const filePath = path.join(translationDir, `${language}.json`);

  // Read the existing JSON file
  let existingTranslations = {};
  try {
    existingTranslations = JSON.parse(fs.readFileSync(filePath, "utf8"));
  } catch (error) {
    console.error(`\x1b[31mError:\x1b[0m Error reading ${filePath}:`, error);
    return;
  }

  // Add the new translation key and value to the specified category
  existingTranslations[category][key] = value;

  // Write the updated JSON back to the file
  try {
    fs.writeFileSync(filePath, JSON.stringify(existingTranslations, null, 2));
    console.log(`\x1b[32mSuccess:\x1b[0m Updated translations for ${language}`);
  } catch (error) {
    console.error(`\x1b[31mError:\x1b[0m Error writing ${filePath}:`, error);
  }
});
