Every few months, a new JavaScript framework drops and the internet collectively screams:
“This will replace everything!”
Meanwhile, I’m over here quietly building with MERN like:
“bro… it just works.”
MERN isn’t the newest, shiniest, or trendiest stack anymore —
but honestly?
It’s still one of the most powerful and reliable stacks for modern side projects.
Here’s why.
💡 Why I Still Choose MERN
When you’re building something ambitious (or chaotic), you want tools that don’t betray you at 3AM.
MERN gives you that stability, simplicity, and familiarity.
MongoDB → flexible
Express → clean
React → powerful
Node → fast
It’s all JavaScript, all the way down.
Which means your brain doesn’t have to context-switch languages every two seconds.
🧱 Reason #1 — Build Anything With One Language
Frontend? JS.
Backend? JS.
Database queries? basically JS.
It makes the full-stack workflow way easier for beginners and pros.
There’s something magical about using the same mental model across your entire app.
🧱 Reason #2 — React Is Still a Beast
People love talking about the “React alternatives.”
But React still dominates for THREE reasons:
HUGE ecosystem
Endless UI libraries
Battle-tested design patterns
And if you love components, reactivity, animations, and smooth UX… well, React still delivers.
🧱 Reason #3 — MongoDB Is a Lifesaver for Fast Builds
Schemaless = speed.
You can ship features quickly without rewriting your database every time your idea changes.
Perfect for side projects where the idea evolves…
and sometimes mutates.
🧱 Reason #4 — Express + Node = Simple, Clean, Predictable
Express is that friend who never overcomplicates things.
Need a route? Done.
Need middleware? Easy.
Need an AI endpoint? Plug and play.
It’s perfect for:
REST APIs
Authentication
Payment integrations
AI model requests
Real-time sockets
No unnecessary drama.
Just pure backend goodness.
🧱 Reason #5 — Perfect for AI-Powered Projects
With AI becoming part of almost every modern app, MERN just… fits.
You can easily:
call AI APIs
store chat logs
save generated images
manage credits
run webhooks
handle real-time chat
And if you pair it with tools like Socket.io or ImageKit, it becomes even more powerful.
😭 But Yes… MERN Can Hurt You Too
Let’s not pretend it's all magical.
Here are the things that almost made me quit the stack more than once:
🔥 CORS (why does this thing have anger issues?)
🔥 JWT tokens expiring at the worst possible times
🔥 MongoDB connection errors that appear out of nowhere
🔥 Deploying Node servers—always an adventure
🔥 Environment variables disappearing in production
MERN is strong, but it definitely keeps you humble.
🌟 What I Learned
MERN is still one of the most practical stacks
It scales well with your ideas
It’s beginner-friendly but powerful enough for pros
AI + MERN is a dream combo
Deployment is still a villain arc, but manageable
You ship faster because the ecosystem is massive
But the biggest takeaway?
You don’t need the newest stack — you need the stack that lets you build.
🎉 Final Thoughts
MERN may not trend as loudly as it used to, but it continues to be one of the best choices for:
fast projects
ambitious apps
AI integrations
real-time systems
collaborative platforms
or your next masterpiece
If you’re looking for a stack that helps you go from idea → real app without losing your sanity…
MERN is still that stack.
And honestly?
It’s probably going to stay that way for a long time.
