CORS in React… Every MERN developer’s villain at least once You just want to fetch some data from your backend… and suddenly — “Access to fetch has been blocked by CORS policy” And then the journey begins: ✔️ Google: “how to fix CORS in React” ✔️ Add ""proxy"" in package.json ✔️ Try random Stack Overflow solution ✔️ Still not working 🙂 But here’s the real thing most beginners miss 👇 CORS is not a frontend problem. It’s a backend security feature. 👉 Browsers block requests when frontend & backend are on different origins 👉 Server must allow it using headers like: "Access-Control-Allow-Origin" In Express (Node.js), it’s usually just: "app.use(cors())" And boom — problem solved So yeah… CORS isn’t a bug. It’s just the internet saying: “Hey… are you allowed to access this?” 😄 Every MERN developer goes through this phase… and survives 💪 What was your first CORS struggle? 👇 #MERN #React #NodeJS #WebDevelopment #DeveloperLife #Coding #BuildInPublic
So true 😄 I remember spending hours thinking something was wrong with my React code… turns out it was just a backend CORS issue. That small fix, big lesson 👍
I faced this when I started my first project 😅 Spent a lot of time thinking something was wrong with my code… Later realized it was just CORS.
So true 🤣
Great representation
I have been there. It's frustrating to see your own backend being stopped from communicating. First time I got a CORS issue, I spent hours working on it. Now I know exactly what to do or better prevent it from happening at all.
