If you’ve ever wished for a full-stack React framework that feels like Ruby on Rails but works in the modern JavaScript world, Blitz.js might be your new best friend. Think of it as Next.js on steroids – it keeps all the good parts of Next.js while adding powerful tools for building full-fledged apps faster.
Let’s explore what Blitz.js is, what makes it special, how to install it step by step, and answer some beginner FAQs.
What is Blitz.js?
Blitz.js is a full-stack framework for React that’s built on top of Next.js. It’s designed to give developers everything they need in one package—frontend, backend, database, authentication, and even code scaffolding.
If you’ve used Next.js, you already know the basics. But Blitz takes it further by removing a lot of the repetitive tasks and giving you a “batteries-included” experience.
Key Features of Blitz.js
Below are some features that make Blitz.js shine,
- Full-stack in one place: No need to separately set up frontend and backend projects.
- Zero-API Data Layer: You don’t have to manually write API routes. Your functions can be called directly from the frontend.
- Authentication out of the box: User signup, login, and sessions are already baked in.
- Code scaffolding: Quickly generate pages, forms, and CRUD with simple commands.
- Prisma integration: Works beautifully with Prisma ORM for database management.
- Next.js compatible: You still have SSR (Server-Side Rendering), SSG (Static Site Generation), and all the Next.js features you love.
Advantages of Blitz.js
- Saves tons of setup time for full-stack apps.
- Great developer experience with code generation tools.
- Built-in auth and session management.
- Perfect for startups and MVPs (Minimum Viable Products).
- Uses popular tools like Next.js and Prisma.
Disadvantages of Blitz.js
- Community is still small compared to Next.js.
- Might feel opinionated for some developers.
- Updates are not as frequent as bigger frameworks.
- Overkill if you just need a static site or simple frontend.
Step-by-Step Installation Guide for Blitz.js
Let’s go from scratch and install Blitz.js together.
Step 1: Install Node.js
Make sure you have Node.js v16 or later installed. You can check with:
node -v
If not installed, download from nodejs.org.
Step 2: Create a New Blitz.js App
Run the following command in your terminal:
npx blitz create my-blitz-app
It will ask you a few setup questions. Choose the options you prefer (default is fine for beginners).
Step 3: Navigate to Your Project
cd my-blitz-app
Step 4: Install Dependencies
Blitz will install dependencies automatically, but if needed:
npm install
or
yarn install
Step 5: Run the Development Server
npm run dev
Now visit http://localhost:3000 in your browser, and boom, your Blitz app is running.
Step 6: Explore Authentication
Blitz comes with user login and signup flows out of the box. You’ll already see the auth pages in your project.
FAQ's
Q: Is Blitz.js the same as Next.js?
A: No. Blitz.js is built on top of Next.js. You can think of it as Next.js + full-stack features + batteries included.
Q: Can I use my existing Next.js knowledge?
A: Yes! Most Next.js concepts (pages, routing, SSR, etc.) work the same in Blitz.
Q: Do I need a backend if I use Blitz.js?
A: Not really. Blitz has a zero-API layer, so your frontend can directly call backend functions without writing REST or GraphQL manually.
Q: What database works best with Blitz.js?
A: Blitz is designed to work seamlessly with Prisma, which supports databases like PostgreSQL, MySQL, and SQLite.
Q: Is Blitz.js good for beginners?
A: Yes, if you want to build full-stack apps quickly. But if you only need a static site, stick with Next.js.
Conclusion
Blitz.js is like the fast track to building React full-stack apps. Instead of setting up frontend, backend, and authentication separately, Blitz gives it all to you in one package.
If you’re a startup founder, indie hacker, or beginner developer who wants to build real apps quickly, Blitz.js can save you weeks of setup time.
