Custom Translation Logger

Name: tessl/npm-i18next-client
Rating: 0.69 (1 reviews)
Author: tessl

Build a custom logger plugin for an internationalization system that tracks translation lookups and missing keys for debugging purposes.

Requirements

Create a translation system that:

Implements a custom logger plugin that captures all translation events
Registers the custom logger with the i18n framework
Tracks successful translation lookups and missing translation keys
Provides methods to retrieve logged events for debugging

The logger should maintain separate lists for successful lookups and missing keys, allowing developers to identify translation gaps during development.

Test Cases

Successfully logs a translation lookup when a key is found @test
Records missing key events when translations are not found @test
Allows retrieval of all logged events @test
Works with multiple translation namespaces @test

   * Creates a new translation logger instance
   */
  constructor();

  /**
   * Gets the plugin type identifier
   * @returns {string} The type of plugin ('logger')

  /**
   * Initializes the logger with i18next services
   * @param {object} services - i18next services object
   * @param {object} options - Logger options
   */

  /**
   * Logs general messages
   * @param {...any} args - Arguments to log

  /**
   * Logs warning messages
   * @param {...any} args - Arguments to log
   */
  warn(...args);

  /**
   * Logs error messages
   * @param {...any} args - Arguments to log
   */
  error(...args);

  /**
   * Gets all successful translation lookups
   * @returns {Array<{key: string, namespace: string, language: string}>} Array of lookup records
   */
  getSuccessfulLookups();

  /**
   * Gets all missing translation keys
   * @returns {Array<{key: string, namespace: string, language: string}>} Array of missing keys
   */
  getMissingKeys();

  /**
   * Clears all logged events
   */
  clear();
}

/**
 * Initializes i18next with the custom logger and sample translations
 * @param {TranslationLogger} logger - The custom logger instance
 * @returns {Promise<object>} Initialized i18next instance
 */
