A highly customizable and versatile GraphQL client for React

A highly customisable and versatile GraphQL client for React

✨ Features

• 📦 One package to get a working GraphQL client in React
• ⚙️ Fully customisable behaviour via "exchanges"
• 🗂 Logical but simple default behaviour and document caching
• ⚛️ Minimal React components and hooks

urql is a GraphQL client that exposes a set of React components and hooks. It's built to be highly customisable and versatile so you can take it from getting started with your first GraphQL project all the way to building complex apps and experimenting with GraphQL clients.

While GraphQL is an elegant protocol and schema language, client libraries today typically come with large API footprints. We aim to create something more lightweight instead.

Some of the available exchanges that extend urql are listed below in the "Add on Exchanges" list including a normalized cache and a Chrome devtools extension.

🏎️ Quick Start Guide

First install urql and graphql:

yarn add urql graphql
# or
npm install --save urql graphql

Create a client for your endpoint url and wrap your app with a <Provider> component which urql exposes:

import { Provider, createClient } from 'urql';

const client = createClient({
  url: 'http://localhost:1234/graphql', // Your GraphQL endpoint here
});

ReactDOM.render(
  <Provider value={client}>
    <YourApp />
  </Provider>,
  document.body
);

This allows you to use the useQuery hook in your function component to fetch data from your server:

import { useQuery } from 'urql';

const YourComponent = () => {
  const [result] = useQuery({
    query: `{ todos { id } }`,
  });

  const { fetching, data } = result;
  return fetching ? <Loading /> : <List data={data.todos} />;
};

Alternatively you can take advantage of the <Query> component:

import { Query } from 'urql';

<Query query="{ todos { id } }">
  {({ fetching, data }) =>
    fetching ? <Loading /> : <List data={data.todos} />
  }
</Query>;

📦 Add on Exchanges

urql can be extended by adding "Exchanges" to it, which you can read more about in our docs! Here's just a couple of them.

• @urql/devtools: A Chrome extension for monitoring and debugging
• @urql/exchange-graphcache: A full normalized cache implementation (beta)
• @urql/exchange-suspense: An experimental exchange for using <React.Suspense>
• urql-persisted-queries: An exchange for adding persisted query support

You can find the full list of exchanges in the docs.

💡 Examples

There are currently three examples included in this repository:

• Getting Started: A basic app with queries and mutations
• Using Subscriptions: An app that demos subscriptions
• SSR with Next: A Next.js app showing server-side-rendering support
