React Query information

What are some common challenges developers face when integrating React Query into an existing React application?

One common challenge developers encounter is adapting existing state management patterns to leverage React Query’s data-fetching and caching mechanisms effectively. Transitioning from traditional global state solutions like Redux or Context to React Query often requires rethinking how server state and client state are separated and managed. Additionally, ensuring proper cache invalidation and understanding query keys can be tricky at first, but mastering these concepts is essential for optimal application performance. Collaborating with teammates to establish best practices for query structure and error handling helps streamline the adoption process.

What is the difference between React Query vs React Developer?

AspectReact Query
Required SkillsData fetching, caching, server state management, React hooks
Work EnvironmentFrontend development, UI/UX focus, JavaScript/React projects
Industry UsageWeb applications, SaaS platforms, e-commerce sites

React Query is a library for managing server state in React applications, focusing on data fetching and caching. A React Developer builds entire user interfaces, often using React Query as a tool within their skill set. While React Developers need broader knowledge of React, JavaScript, and UI design, React Query specialists focus on efficient data management within React apps. Both roles often overlap in web development teams, but React Query is a specific library skill, whereas React Developer is a broader role.

What is React Query?

React Query is a powerful data-fetching and state management library for React applications. It simplifies the process of fetching, caching, synchronizing, and updating server data in your UI, eliminating the need for complex state management solutions or manual data handling. By handling background updates, caching, and stale data, React Query helps developers build fast and responsive applications with less boilerplate code. It works seamlessly with REST, GraphQL, and other data sources, making it a versatile choice for modern web development.

What are the key skills and qualifications needed to thrive as a React Query developer, and why are they important?

To thrive as a React Query Developer, you need a solid understanding of JavaScript, React, and asynchronous data fetching patterns, along with experience in frontend development. Proficiency with React Query itself, familiarity with RESTful APIs, GraphQL, and tools like Axios or Fetch are typically required. Strong problem-solving skills, attention to detail, and effective communication set top candidates apart in this role. Mastery of these skills ensures efficient data management, optimal user experiences, and smooth integration of complex data-driven features in modern web applications.

Job description

Who are we?

At Newcode.ai, we're on a mission to reshape how organizations put AI to work in their day-to-day operations. In few months, we've moved from vision to reality-building products our clients truly love. As part of our fast-growing and highly ambitious team, you won't just drive the future of AI-you'll help define it.

The role

You'll build features the whole way through: the FastAPI service and data work on the back, the React interface on the front. Most of what we build puts a language model in front of someone doing real work, so a typical feature might mean wiring up retrieval and an LLM call on the backend, then building the streaming, document-heavy UI that makes it usable. 


We want someone who can carry a feature from idea to production without handing it over a wall. You should be at home in a Celery task and in a React component, and able to handle routine work on either side without waiting for a specialist to unblock you.

Requirements

What You'll Do
  • Building AI features end to end, API through UI. 
  • Making models usable: streaming responses, real-time updates, and interfaces that handle a lot of documents without feeling slow. 
  • Owning quality and architecture on both sides of a feature. 
  • Pulling in our frontend or backend specialists when something needs real depth, and handling the rest yourself. 
Who You Are
  • At least five years building and shipping fullstack work. Depth matters more to us than the number. 
  • Comfortable on both sides for real: you can design a clean API and build a good UI on top of it. 
  • You care how it turns out: readable code, a UI that feels right, an architecture you'd defend. 
  • You use AI coding tools (Claude Code, Cursor, Copilot) and use them well. They make you faster; they don't write code you don't understand, and you wouldn't pass sloppy AI output in review. 
  • Keen to go deeper on LLMs, RAG, and agents. 
  • Fine working in a startup that shifts under you. 
Experience we expect with the stack
  • React: 5+ years 
  • TypeScript: 3+ years 
  • FastAPI / Python: 3+ years 
  • PostgreSQL 
  • Redis: 2+ years 
  • Tailwind CSS: 1+ year 

Nice to have: Next.js, React Query, Zustand, shadcn/ui; LangChain or LlamaIndex; streaming over SSE or WebSocket. 

Benefits

Why Newcode.ai?
  • Join a collaborative, high-energy team where your ideas are heard and your impact is real.
  • Help design, build, and launch products shaping the future of artificial intelligence.
  • Work flexibly, in English, from anywhere in the EU.

At Newcode.ai, you don't just see the future-you help create it.
