Examples

Getting started

If you're looking to upgrade from [email protected] to graphiql@2, check out the migration guide!

UMD

With unpkg/jsdelivr, etc.:

<link href="https://unpkg.com/graphiql/graphiql.min.css" rel="stylesheet" />
<script crossorigin src="https://unpkg.com/graphiql/graphiql.min.js"></script>

(see: Usage UMD Bundle below for more required script tags)

Usage

Using as package

The graphiql package can be installed using your favorite package manager. You also need to have react,react-dom and graphql installed which are peer dependencies of graphiql.

npm install graphiql react react-dom graphql

The package exports a bunch of React components:

  • The GraphiQLProvider components renders multiple context providers that encapsulate all state management
  • The GraphiQLInterface component renders the UI that makes up GraphiQL
  • The GraphiQL component is a combination of both the above components

There is a single prop that is required for the GraphiQL component called fetcher. A fetcher is a function that performs a request to a GraphQL API. It may return a Promise for queries or mutations, but also an Observable or an AsyncIterable in order to handle subscriptions or multipart responses.

An easy way to get create such a function is the createGraphiQLFetcher method exported from the @graphiql/toolkit package. If you want to implement your own fetcher function you can use the Fetcher type from @graphiql/toolkit to make sure the signature matches what GraphiQL expects.

The following is everything you need to render GraphiQL in your React application:

import { createGraphiQLFetcher } from '@graphiql/toolkit';
import { GraphiQL } from 'graphiql';
import React from 'react';
import { createRoot } from 'react-dom/client';
import 'graphiql/graphiql.css';

const fetcher = createGraphiQLFetcher({ url: 'https://my.backend/graphql' });

const root = createRoot(document.getElementById('root'));
root.render(<GraphiQL fetcher={fetcher} />);

Using as UMD bundle over CDN (Unpkg, JSDelivr, etc)

There exist pre-bundled static assets that allow you to easily render GraphiQL just by putting together a single HTML file. Check out the index.html file in the example project in this repository.

Customize

GraphiQL supports customization in UI and behavior by accepting React props and children.

Props

For props documentation, see the API Docs

Children

Parts of the UI can be customized by passing children to the GraphiQL or the GraphiQLInterface component.

  • <GraphiQL.Logo>: Replace the GraphiQL logo with your own.

  • <GraphiQL.Toolbar>: Add a custom toolbar below the execution button. Pass the empty <GraphiQL.Toolbar /> if an empty toolbar is desired. Use the components provided by @graphiql/react to create toolbar buttons with proper styles.

  • <GraphiQL.Footer>: Add a custom footer shown below the response editor.

Plugins

Starting with graphiql@2 there exists a simple plugin API that allows you to build your own custom tools right into GraphiQL.

There are two built-in plugins that come with GraphiQL: The documentation explorer and the query history. Both can be toggled using icons in the sidebar on the left side of the screen. When opened, they appear next to the sidebar in a resizable portion of the screen.

To define your own plugin, all you need is a JavaScript object with three properties:

  • title: A unique title for the plugin (this will show up in a tooltip when hovering over the sidebar icon)
  • icon: A React component that renders an icon which will be included in the sidebar
  • content: A React component that renders the plugin contents which will be shown next to the sidebar when opening the plugin

You can pass a list of plugin objects to the GraphiQL component using the plugins prop. You can also control the visibility state of plugins using the visiblePlugin prop and react to changes of the plugin visibility state using the onTogglePluginVisibility prop.

Inside the component you pass to content you can interact with the GraphiQL state using the hooks provided by @graphiql/react. For example, check out how you can integrate the OneGraph Explorer in GraphiQL using the plugin API in the plugin package in this repo.

Theming

The GraphiQL interface uses CSS variables for theming, in particular for colors. Check out the root.css file for the available variables.

Overriding these variables is the only officially supported way of customizing the appearance of GraphiQL. Starting from version 2, class names are no longer be considered stable and might change between minor or patch version updates.

Editor Theme

The colors inside the editor can also be altered using CodeMirror editor themes. You can use the editorTheme prop to pass in the name of the theme. The CSS for the theme has to be loaded for the theme prop to work.

// In your document head:
<link
  rel="stylesheet"
  href="https://cdnjs.cloudflare.com/ajax/libs/codemirror/5.23.0/theme/solarized.css"
/>
// When rendering GraphiQL:
<GraphiQL editorTheme="solarized light" />

You can also create your own theme in CSS. As a reference, the default graphiql theme definition can be found here.
