Building a Pokemon App with GraphQL and Apollo


GraphQL is a query language for APIs that allows you to efficiently retrieve only the data you need, while Apollo is a state management library that simplifies data handling. Together, these technologies enable the creation of robust and performant web applications. In this tutorial, we'll walk through building a Pokemon app using GraphQL and Apollo.


  • Node.js v18+
  • Code editor
  • Web browser

React Application Setup

  1. Create a new React app: npx create vite@latest pokemon-app -- --template react
  2. Install dependencies: npm install
  3. Start the development server: npm run dev

GraphQL and Apollo Integration

  1. Install Apollo Client: npm install @apollo/client
  2. Import necessary modules: import { ApolloClient, ApolloProvider, InMemoryCache } from "@apollo/client";
  3. Create an Apollo client instance with a GraphQL API endpoint: const client = new ApolloClient({ uri: "", cache: new InMemoryCache(), });
  4. Wrap the <App> component with ApolloProvider to provide the client to all components: ReactDOM.createRoot(document.getElementById("root")).render(<React.StrictMode><ApolloProvider client={client}><App /></ApolloProvider></React.StrictMode>);

Fetching Pokemon Data

  1. Create a PokemonsContainer component: export function PokemonsContainer() { ... }
  2. Use the useQuery hook to execute a GraphQL query: const { loading, error, data } = useQuery(GET_POKEMONS, { variables: { first: 5 }, });
  3. Render the data: <div className="container">{pokemons && => <Pokemon key={} pokemon={pokemon} />)}</div>

GraphQL Query

Create a GraphQL query named GET_POKEMONS:

query pokemons($first: Int!) {
  pokemons(first: $first) {
    attacks {
      special {

Pokemon Component

Create a Pokemon component to render individual Pokemon data: export function Pokemon({ pokemon }) { ... }

Styling the Application

Customize the application's appearance with CSS in index.css:

.pokemon {
  background-color: #fff;
  border: 1px solid rgba(0, 0, 0, 0.125);
  border-radius: 0.25rem;
  box-shadow: 0 0.125rem 0.25rem rgba(0, 0, 0, 0.075);
  overflow: hidden;


This tutorial demonstrated how to build a Pokemon app using GraphQL and Apollo. By leveraging these technologies, you can create data-driven applications that provide a seamless user experience while optimizing performance and efficiency.
