Day25:

VALIDATION!

x-Watch the video, then do the same thing for your Videogames app from Day24. x-Validate input, return errors on the backend. Catch them on the frontend and make your form user friendly!

Defien your own validation rules. Some examples: x- is your input type the type you expect it to be? ie: can i pass an array instead of a string as .req.body.name and pass your validation, breaking shit? x- length checks

• bad word filters

Day24:

Combining express and Svelte (SERVER and CLIENT), as well as "cheating" with a database by using a file!

HOMEWORK:

Create a frontend with Svelte and a backend with Express, like I do in my video, for a model of "Videogames", stored in a file "videogames.json". See my video for file structure! Your form should have:

• Name
• Platform it's on
• Year of release
• Genre
• ESRB rating
• Boolean value of whether it's good or not.

BONUS: Add an IMAGE FILE UPLOADER to the Form, and save it in the backend as well! ( ask for help if you need )
