What are some best practices for using `body-parser` in a production Express application?

Best practices include: 1. **Always specify the `limit`:** Set a reasonable size limit to prevent denial-of-service. 2. **Use error handling:** Implement middleware to gracefully handle parsing errors. 3. **Choose the appropriate middleware:** Select `express.json()`, `express.urlencoded()`, or `bodyParser.raw()` based on the expected request body format. 4. **Stay updated:** Keep `body-parser` or `express` updated to benefit from security fixes and performance improvements. 5. **Consider using a configuration file:** Manage middleware configurations (like limits) in a separate configuration file.
