AI shortens the distance between idea and running code, not between idea and correctness. I see this a lot when I check the generated code.

How OAuth works 🔐 1️⃣ You try to access a protected resource → The app doesn’t log you in directly. Instead, It redirects you to an Authorization Server 2️⃣ You log in to the Authorization Server → (e.g. Google, GitHub) It: ✔️ Authenticates you ✔️ Asks for permissions (scopes) 3️⃣ If approved ✅, the Authorization Server redirects you back → with an authorization code 4️⃣ The app exchanges this code for an access token → This happens server-to-server (secure) 5️⃣ The app uses the access token → Sends it to the Resource Server (API) 6️⃣ If the token is valid ✅ → You get access to the protected data

@sevalla_hosting Add Google login to your project, and logins will jump up by 50%! At least!

POST vs PATCH in simple terms: POST → creates a new resource Example: POST /users Use it when you want to add something new to the server. PATCH → partially updates an existing resource Example: PATCH /users/123 Use it when you want to change only specific fields without replacing the whole record. Quick rule: POST = create new PATCH = update existing partly A lot of beginners mix these up, but this is the easiest way to remember it.

How the REST API works: REST (Representational State Transfer) is an architectural style for designing networked applications. It uses standard HTTP methods to perform operations on resources identified by URLs. Key HTTP methods: GET: Retrieve data from the server POST: Create a new resource PUT: Update an existing resource DELETE: Remove a resource PATCH: Partially update a resource Core principles: Stateless: Each request contains all information needed. No client context stored on the server. Client-Server: Separation of concerns between client and server. Uniform Interface: Standardized way to interact with resources via URLs and HTTP methods. Resource-Based: Everything is a resource identified by a URL. Cacheable: Responses can be cached to improve performance.

How API rate limiting works: • Rate limiting controls how many API requests a user can make in a time window (e.g., 100 requests per minute) • When you exceed the limit, the API returns a 429 error (Too Many Requests) Common strategies: - Token bucket: Refills tokens at a fixed rate - Fixed window: Hard limit resets at specific intervals - Sliding window: More flexible, tracks requests over rolling time Rate limit info is usually in response headers: - X-RateLimit-Limit: Max requests allowed - X-RateLimit-Remaining: Requests left - X-RateLimit-Reset: When the limit resets Why it exists: - Prevents server overload - Stops abuse and DDoS attacks - Ensures fair usage across all users Best practice: Implement exponential backoff when you hit limits (wait longer between retries)

@sevalla_hosting Definitely the most popular one.

I’ve been trying to get better at the boring-but-important security stuff (the things you only notice after something breaks 😅). I started Scrimba’s “Learn Cybersecurity” and it’s refreshingly practical: ✅ security mindset for everyday dev work ✅ auth/identity basics that actually matter ✅ input + data safety ✅ rate limiting/throttling without the fluff It’s only a few hours, and the lessons are bite-sized. Worth a weekend if you ship web apps.

@razvanmuntian Csaba here 😀😉

@SaveToBookmarks thank you so much for the share! 🤩🤩

Amazing work, Razvan!

When your project needs one tiny util, and npm installs the shipping company. ⚓️

@sevalla_hosting There is only a slight difference between the two.

Which LLM is better for coding?

I pushed Replit again this week… This time I asked it to build an Image Color Extractor app — upload any image → instantly get the dominant colors + clean palette you can copy. And yep… one prompt was enough to get a working app.

@sevalla_hosting I've moved 4 of my Astro sites over to Sevalla and am testing now. So far so good!

@MentorWebDev @csaba_kissi As well as Databases and static sites.

@csaba_kissi Sevalla supports Docker.

Which one is your preferred hosting?

Built an HTTP client for modern PHP: Relay. Fiber-native concurrency, immutable requests, no exceptions for 404/500 - just explicit Success or Failure signals. Concurrent code that reads synchronously, zero bloat, ext-curl only. Not a Guzzle replacement, a clean-slate transport for PHP 8.5+. sevalla.com/blog/relay-fib…

@sevalla_hosting It's like when you look into a 5K lines-long AI-generated app.

Programmer learning vs. 10 years later

@sevalla_hosting Best result in every category. Congrats!

We're proud! 🙌👇

Hi everyone! My 12 year-old little sister has recently started learning UI design. She can’t have her own X account yet, so I’m sharing her work here. 😊 She created this app concept for busy school days, a quick mood check-in and a mini journal so she can log how she feels even when she doesn’t have much time. If you work in UI/UX, we’d really appreciate any constructive feedback or beginner tips. I’ll make sure to share all your replies with her. 😁
