Best practices to verify files before uploading to S3?

I use multer to upload files to the server to a temp folder (ensuring it is *.pdf extension) with an API (using import { tmpdir } from 'os';)

// Configure multer for file uploads
const upload = multer({
  dest: tmpdir(), // Use system's temporary directory
  limits: { fileSize: 10 * 1024 * 1024 } // 10MB size limit
});

export const uploadFileApi = async (req, res, context) => {
  // Check if user is authenticated
  if (!context.user) {
    return res.status(401).json({ message: 'Unauthorized' });
  }

  // Set up multer middleware for single file upload
  const singleUpload = upload.single('file');

  singleUpload(req, res, async function(err) {
    // Handle upload errors
    if (err) {
      return res.status(400).json({ message:

File upload error: ${err.message}

 });
    }

    // Check if file was provided
    if (!req.file) {
      return res.status(400).json({ message: 'No file was provided' });
    }

    try {
      // File successfully uploaded to temporary location
      console.log('File uploaded successfully:', req.file.originalname);
      
      // Return success response
      return res.json({ 
        success: true,
        filename: req.file.originalname,
        path: req.file.path
      });
    } catch (error) {
      // Handle any other errors
      console.error('Error processing file:', error);
      return res.status(500).json({ 
        message: 'Error processing uploaded file' 
      });
    }
  });
};

Non-Dev question about APIs

@kapa.ai What would be the difference in the Extension and the Api using wasp:sessionId or for getSessionId() from wasp/client/api? Is the same? Explain the differences, could I get sessionId from API call?

@kapa.ai wasp 0.15.0 to wasp 0.16.2 Error:

[plugin:vite:import-analysis] Failed to resolve import "wasp/client/webSocket/WebSocketProvider" from "src/index.tsx". Does the file exist?

Code (wasp 0.15.0):

import { Server } from 'socket.io'
import { type WebSocketDefinition, type WaspSocketData } from 'wasp/server/webSocket'

What's wrong? What should be in latest wasp version? what's new? how to solve import?
