@NanouuSymeon Good morning Nanou!

Good morning Developers! What are you building today?

@_jaydeepkarale Nice and to the point!

What is JWT actually ??? I've tried my best to summarize it below

@e_opore Very good infographic Dhanian!

API Architecture Patterns

@Shefali__J Good morning Shefali!

The only way to never fail again is to simply never give up. Good morning, everyone🌞

@Shefali__J Have a great day Shefali!

If there is no struggle, there is no progress. Good morning, everyone🌞

@tapasadhikary Animation is so neat! I'm very curious to see how AI further improves it.

6 years ago, I developed this app for my daughter to learn basic arithmetic. For a long time, it was under the dust, and no one looked into it. Now, I want to see how vibe coding will help me wrap up lots of dream features on my shelved side projects.

@sevalla_hosting Another simple explanation!

How API Gateway works: 1. Client → sends request 2. Gateway → routes to service(s) 3. Services → fetch/process data 4. Gateway → returns response But the gateway does more than routing 👇 - Auth (JWT, OAuth) - Rate limiting - Request validation - Response transformation - Logging & monitoring - Caching 👉 One entry point for everything 👉 Keeps your backend clean & scalable

@NanouuSymeon I see some new ones on the list. Nice share Nanou!

Tools Developers Use to Make Beautiful Code Screenshots 🎨 Ray .so 🎨 Carbon 🎨 Codeimg 🎨 Snappify 🎨 Polacode 🎨 CodeSnap 🎨 CodePNG 🎨 Kod .so

@tapasadhikary I've used it for readability a few times.

Do you use the numeric separators(_) in JavaScript? 1_000_000_000 vs 1000000000

@Shefali__J Nice, handy tip!

JavaScript Tip 💡 You can remove whitespace from both ends of a string using the trim() method.

@sevalla_hosting I would say Claude

Which one is the best AI for coding?

Fetch → Store → Render Pattern in React 👇🏻 1. When the app first loads, this code runs automatically and calls a function to fetch all the conversations from the backend. 2. Once the data is received, it is passed into setConversations, which stores it in state. 3. As soon as the state updates, React re-renders the UI, so all the conversations become visible on the screen without doing anything manually. Have you used this pattern?

Remote meeting be like: - Am I audible? - Is my screen visible? Agree? 😄
