Millised on teie peamised panused ja parendused, mida olete rakendanud praegustes projektides?

In current Node.js projects, I have made the following improvements:

• Optimized asynchronous operation handling by replacing callbacks with async/await, which improved code readability and stability.
• Implemented centralized error handling via middleware, simplifying debugging and increasing API reliability.
• Caching frequently requested data using Redis, which reduced database load and sped up server response times.
• Configured request and error logging with Winston, aiding in monitoring and analyzing application performance.

Example of centralized error handling in Express.js:

app.use(async (req, res, next) => {
  try {
    await next();
  } catch (err) {
    console.error(err);
    res.status(500).send('Internal Server Error');
  }
});
