☕🍃 MERN is FAMOUS. But companies still NEED the JAVA STACK.

Tutorial fame is not the same thing as hiring demand.

· java

🔸 TLDR

MERN is one of the best-known full-stack combinations.

But if your goal is employment, especially in enterprise software, don't ignore Java + Spring.

The market needs BOTH; just not always for the same companies.

🔸 WHAT IS THE MERN STACK?

▪️ MongoDB → database

▪️ Express → backend framework

▪️ React → frontend

▪️ Node.js → JavaScript runtime

One language across most of the stack: JavaScript/TypeScript.

And the ecosystem is HUGE.

Stack Overflow 2025:

▪️ JavaScript → 66%

▪️ Node.js → 48.7%

▪️ React → 44.7%

No wonder MERN dominates tutorials, bootcamps and social media. 🚀

🔸 WHAT IS THE JAVA STACK?

There isn't one mandatory Java stack, but a common enterprise setup is:

▪️ Java → backend language

▪️ Spring Boot → application framework

▪️ SQL/PostgreSQL → persistence

▪️ Maven/Gradle → build

▪️ Docker/Kubernetes + Cloud → deployment

Stack Overflow 2025:

▪️ Java → 29.4%

▪️ Spring Boot → ~14.7%

Smaller mindshare?

Maybe.

Small job market?

Definitely not. 👀

🔸 LOOK AT THE JOB MARKET

Recent LinkedIn search snapshots:

🇺🇸 United States

▪️ 8,000+ Java Developer jobs

▪️ 5,905 Java + Spring Boot results

🇫🇷 France

▪️ 4,000+ Java Developer jobs

▪️ 855 Spring Boot results

And GitHub reported Java gaining ~174,700 contributors in 2025:

➡️ +20.73% YoY.

Their explanation?

Steady enterprise-driven growth.

🔸 THIS IS EXACTLY WHAT DANNY THOMPSON NOTICED

On Spring Office Hours with Dan Vega and DaShaun Carter, Danny explained that when he started, everyone was telling him:

MERN. MERN. MERN.

Then he looked at the companies he ACTUALLY wanted to work for.

Java kept appearing.

He learned Java.

And, in his words:

"I owe my entire career to Java."

That's the lesson. 🎯

Don't choose your stack only from YouTube thumbnails.

Look at the companies you want to join.

Look at THEIR job offers.

Look at THEIR production stacks.

🔸 TAKEAWAYS

▪️ MERN has massive developer mindshare.

▪️ React + Node.js remain highly marketable skills.

▪️ But "popular to learn" ≠ "all companies use it."

▪️ Java + Spring remain deeply embedded in enterprise hiring.

▪️ Learn for the MARKET you want to enter; not the algorithm feeding you tutorials.

MERN stack is well known.

But companies still need people who know the Java stack. ☕🍃
