How to useApollo, Configure the Apollo Client in ReactJS
Note: This step is only needed for the Apollo Client method, not for Fetch API or Axios.
Apollo Client is a powerful GraphQL client that works seamlessly with React, You can think of the Apollo Client as your GraphQL interpreter for React. We can configure our Apollo Client by specifying the endpoint
// src/index.js
import { ApolloClient, InMemoryCache, ApolloProvider } from '@apollo/client';
const client = new ApolloClient({
uri: 'https://your-graphql-api-endpoint.com/graphql', // Replace with your GraphQL API endpoint
cache: new InMemoryCache()
});
ReactDOM.render(
<ApolloProvider client={client}>
<App />
</ApolloProvider>,
document.getElementById('root')
);
The above code initializes ApolloClient for GraphQL with the GraphQL API endpoint and caches it. The ApolloProvider component comes under the @apollo/client package. It uses the ApolloProvider component to wrap the App component so that GraphQL functionality is available within the whole App component (meaning the Apollo Client instance will be provided to all the components in our App). Finally renders it in the root element within the HTML document.
With our Apollo Client now ready we can now use it to fetch and update data in our React App.
How to Integrate GraphQL APIs Into Your React.js Projects
Imagine a React.js world where you can specify exactly the data you need and it flows effortlessly tailored to your needs, and react can efficiently update the DOM as and when needed. No more under-fetching or over-fetching of data or wrestling with nested JSON structures.
This dream becomes a reality with the use of GraphQL the rising star of API technology. This article aims to help you integrate the GraphQL API with your React project.
