React and Node in practice with Relay

From zero to full-stack with code-first GraphQL, Koa, Relay Compiler, fragments and mutations.

Available in Portuguese.

Discover RelayFrom zero to full-stack

ReactRelayGraphQLNode.js + KoaTypeScript

Is your React app still relying on useEffect for everything?

-Data fetched in multiple components without a clear source of truth

-Data sharing that becomes difficult across screens and components

-GraphQL types that drift away from the client code

-Fragments scattered around without predictable composition

-Mutations that are hard to update, validate and reflect in the UI

-A Node/Koa backend growing without a clear contract with the frontend

Relay helps organize that flow with fewer manual effects.

What you will learn

Six chapters for connecting React, GraphQL and Node in a full-stack application

React without excessive useEffect

Organize server data and keep components predictable

Code-first GraphQL

Schemas, types and resolvers for clear API and client contracts

Node.js with Koa

Structure the backend and connect GraphQL to the rest of the application

Relay Compiler

Typed queries and generated code that reduce manual frontend work

Fragments that compose screens

Let each component declare and compose the data it really needs

Mutations in practice

Variables, updates and responses that keep the UI in sync

From zero to full-stack

A direct map for connecting a Node/Koa API to React with GraphQL and Relay.

Why this ebook?

React and Node in the same learning path

Code-first GraphQL with explicit contracts

Koa for a small and organized API

Relay Compiler to reduce manual work

Fragments for component-level data composition

Mutations that update the UI with clarity

What you will build

A React + Node application powered by GraphQL and Relay

user-profile.graphql.ts

query UserProfile($id: ID!) {
  user(id: $id) {
    id
    name
    email
  }
}

const data = useLazyLoadQuery(UserProfile, { id });

Who this ebook is for

React developers who want to organize server data more clearly

Node developers who want to build a GraphQL API

Teams starting to work with Relay and GraphQL

Anyone who wants less useEffect and manual synchronization code

Tech leads who need clear contracts between frontend and backend
