3. How to Process and Validate User Submitted Data Securely

Published 5 years ago

Part three of the How to Build Web Apps with Node.js course. This video will teach you how to process user submitted data using Express, then validate that user data with express-validator. It's extremely important to know how to validate backend data, otherwise, you may be subject to cross site scripting or SQL injection attacks.

Sorry for the chameleon-like skin tone changes—I recorded the video using auto white balance which decided to change my skin color every time the background image on the TV changed. Learned something new myself when making this video.
