import versedb from 'verse.db';
 
const adapter = new versedb.connect({
  adapter: "session",
  dataPath: './sessions',
  maxSize: 1000, // for deafualt it will be 10

async function clearSessions() {
  const result = await adapter.clear();
  if (result.acknowledged) {
    console.log('All sessions cleared:', result.message);
  } else {
    console.log('Failed to clear sessions:', result.errorMessage);

Detailed Explanation

1. In-Memory Deletion: The method first clears all session data from memory.

   • All sessions stored in memory are removed.

2. File System Deletion: The method then deletes all session files from the file system.

   • It reads the list of session files from the data path and deletes each file.

3. Logging: Throughout the process, detailed logs are generated for debugging and tracking purposes.

   • Logs include information about session clearing and errors encountered during the operation.
