The code defines a storeChatHistory function that stores chat history data in a JSON file using Node.js's built-in fs and path modules, and exports it as a module.

Alternatively, you can condense it into two sentences:

The code uses Node.js's built-in modules to interact with files and paths, and defines a storeChatHistory function that stores chat history data in a JSON file. This function is then exported as a module for use in other parts of the application.

Run example

npm run import -- "cache chat logs"

cache chat logs

const fs = require('fs')
const path = require('path')
const CHAT_PATH = path.join(__dirname, '..', 'Resources', 'Projects', 'conversations')

function storeChatHistory (cellId, mtime, summary, emotions, category, hash, date, from, to) {
  let chatCacheFile = path.join(CHAT_PATH, path.basename(cellId).replace(/.log\[[0-9]*\]/, '') + '.json')
  let chatCache = {}
  if(fs.existsSync(chatCacheFile))
    chatCache = JSON.parse(fs.readFileSync(chatCacheFile).toString('utf-8'))
  chatCache[cellId] = {
    mtime,
    summary,
    emotions,
    category,
    hash,
    date,
    from,
    to
  }
  fs.writeFileSync(chatCacheFile, JSON.stringify(chatCache, null, 4))
}

module.exports = {
  storeChatHistory
}

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

// Define the path to the chat cache directory
const CHAT_PATH = path.join(__dirname, '..', 'Resources', 'Projects', 'conversations');

function storeChatHistory(cellId, mtime, summary, emotions, category, hash, date, from, to) {

Code Breakdown

Modules and Variables

• fs: The built-in Node.js fs (File System) module for interacting with files.
• path: The built-in Node.js path module for working with file paths.
• CHAT_PATH: A constant representing the path to a directory containing chat history files.

storeChatHistory Function

• A function that stores chat history data in a JSON file.
• It takes 9 parameters:
  • cellId: The ID of the chat.
  • mtime: The modification time of the chat.
  • summary: A summary of the chat.
  • emotions: Emotions expressed during the chat.
  • category: The category of the chat.
  • hash: A hash of the chat.
  • date: The date of the chat.
  • from: The sender of the chat.
  • to: The recipient of the chat.
• It follows these steps:
  1. Creates a file path for the chat cache file based on the cellId.
  2. Reads the chat cache file if it exists.
  3. Creates a new chat cache object.
  4. Adds the chat history data to the cache object.
  5. Writes the updated cache object to the chat cache file.

Module Exports

• The storeChatHistory function is exported as a module.
