SolidJS vs. Blitz.js

What is SolidJS?

SolidJS is a modern reactive JavaScript library for building fast, declarative user interfaces. Inspired by React, it focuses on fine-grained reactivity and compiles templates to efficient JavaScript code, making applications both lightweight and performant.

Unlike React, SolidJS doesn’t use a virtual DOM. Instead, it updates only the parts of the DOM that change, resulting in better performance and smaller bundle sizes.

Key Features of SolidJS

×

• Fine-grained reactivity: Updates DOM precisely where needed, without re-rendering entire components.
• JSX support: Uses JSX syntax, making it easy for React developers to learn.
• No Virtual DOM: Direct DOM updates for better performance and lower memory usage.
• Small bundle size: Lightweight, leading to faster load times.
• Component-based: Similar to React, it uses reusable, composable components.
• TypeScript support: First-class TypeScript support for type safety.
• Simple learning curve: Easy for developers familiar with React or modern frontend frameworks.

Advantages of SolidJS

• Performance: Outperforms most frameworks thanks to fine-grained reactivity and DOM compilation.
• React-Like Syntax: Easy for React developers to adopt.
• Small & Lightweight: Tiny runtime with minimal overhead.
• Flexible State Management: Built-in signals and stores reduce the need for external libraries.
• SSR Ready: Great for SEO-driven apps like blogs or e-commerce.

Disadvantages of SolidJS

• Smaller Ecosystem: Fewer libraries, tools, and community packages compared to React or Vue.
• Learning Curve: React developers may need to unlearn Virtual DOM patterns.
• Evolving Framework: Still relatively young, so some integrations (like CMS or UI libraries) may require custom solutions.
• Smaller Community: Less support and fewer tutorials compared to React.

What is Blitz.js ?

Imagine you wanto to build an app but setting up frontend, backend, APIs, database and it feels like overextended right ? That’s where Blitz.js comes in.

Blitz is like this super handy fullstack framework that sits on top of Next.js yup, the one you probably already know. Think of it like Rails but for React. You get Next.js goodies like (SSR, file-based routing, etc.), but Blitz throws in extra magic — like a zero-API data layer, built-in auth system, and easy database integration with Prisma.

Basically it is less boilerplate, more actual building.

Key Features of Blitz.js

×

• Zero-API Data Layer – call server functions straight from the client, no need to write API endpoints manually.
• Built on Next.js – so you don’t lose all the SSR/SSG goodness.
• Auth included – login/logout stuff already sorted.
• Code Generation – scaffolding to spin up queries, pages, mutations super fast.
• TypeScript ready – works smooth with TS.
• Database via Prisma – easy database access, feels natural.
• Plugins – add common stuff like Tailwind, auth, etc. with one command.
  

Advantages of Blitz.js

• All-in-one: You don’t need to glue 10 tools together.
• Boosts productivity: Code scaffolding saves so much time.
• Zero-API layer: Less boilerplate, no boring API wiring.
• Still Next.js inside: You can keep SSR, static exports, etc.
• Databases: Works great with Prisma and SQL databases.
• Community is small but passionate: New recipes, ideas keep coming.

Disadvantages of Blitz.js

• Might be overkill: If all you need is a tiny static site, Blitz is too heavy.
• New learning curve: You need to understand queries/mutations instead of normal APIs.
• Smaller community: Not as huge as Next.js, so fewer tutorials and resources.
• Dependent on Next.js: Since it’s built on Next, any big shift in Next.js affects Blitz.
• Still maturing: Some features and ecosystem tools are not as polished as older frameworks.
