remove unused dependencies? Importance?

Just wondering if unused dependencies (in package.json) effect anything other than install time (and potentially deployment-time)? i'm taking a course, they provided some starter code - there was an unused dependency - I asked if i should remove it, they said "if you want" - so i'm trying to find out!...

Database setup for a simple login and registration page in terms of having a "remember me" function

I'm not sure how to setup my database to have a "Remember me" function in order to handle bypassing login. I know you use a cookie with a encoded string and other stuff but the database setup itself is a bit odd. I'm using a Postgres database and so far here are the fields I thought of... ``` user_id AUTOINCREMENT INTEGER email TEXT NOT NULL...

If Sveltekit, Next, Nuxt, are "Fullstack" frameworks, why would you need a backend language?

Am I to assume that sure, the Fullstack Frameworks can do fullstack, but they're limited to a certain point? they can handle API calls, server side rendering, off the top of my head, what's missing that a backend language solves?

When to use htmlspecialchars vs filter_input ?

im confused when using htmlspecialchars vs filter_input for preventing bad input into php. I have got the hang of using prepared queries but I've not noticed when using the other two mentioned functions. Is htmlspecialchars mainly for outputting html to prevent XSS and is filter_input for handling the user input to prevent it from going through to cause harm?

PageSpeed Insights and GTMetrix Score Reading Is Difficult

I'm a relatively new developer. Last year I built a CMS in plain PHP, HTML, CSS, and JS, since that was what my boss of the startup company wanted during that time. Optimizing for page speed and PSI was easy because I know where to look since I built the cms and the website. Last November, I found a new job, fairly known to create websites for real estate agents and/or companies. They use wordpress, and a bunch of different plugins related to Real Estate which I'm very not familiar with. I receive daily tasks from updating the contact forms and plugins, to updating layouts and modules of different sites. However, one of my biggest pain points is optimizing for PSI and GTM. In a day if i get one of those kind of task, I feel like giving up. I know it's mainly because I don't fully understand what the score says or what the errors are saying whenever I run a website on those tools. It feels to me like when I change something on a wordpress site that I'm working on, it's never consistent if what I changed was good or bad. For example, I changed one image, and run both tools. at first they might give me a good score, then wait for a bit to run it again, boom, bad score. I tried looking up for YT videos to see If there's someone or something I can learn from optimizing a wordpress site, but all i get is "install this plugin, install that plugin" ...

Laravel 10 Migration

I'm having a world of trouble with migration. As I understand it you need to have an existing database to perform a migration. I'm on Windows 10 and am trying to create and export a database for Laravel to do a migration on. Can this be done with XAMPP and phpmyadmin? Apparently exporting is not possible with no tables BUT Laravel wants to create the tables itself during the migration process. This CAN'T be this convoluted - can it???? How does one do this?...
