# GraphiQL

> **FORKED version** this is not the canonical version of graphiql

This version has been modified to use `import` instead of `require` and will lag behind the original. You probably want to view [graphql/graphiql](https://github.com/graphql/graphiql)

> **Breaking Changes & Improvements:** several interfaces are being dropped for new ones for GraphiQL 2.0.0! Read more in [this issue](https://github.com/graphql/graphiql/issues/1165)

> **[`graphiql@1.0.0`](https://github.com/graphql/graphiql/milestone/3)** is coming soon & will provide a stable release with react 16, graphql 15 support, fixes, and a headers tab

> **[`graphiql@2.0.0-beta`](https://github.com/graphql/graphiql/issues/983)** is a much larger ongoing effort that introduces plugins, i18n, and so many more features after a substantial rewrite using modern react.

## Live Demos

We have a few demos of `master` branch via the default netlify build (the same URL paths apply to deploy previews on PRs):

1. [`graphiql.min.js` demo](https://graphiql-test.netlify.com/) - the min.js bundle for the current ref
2. [`graphiql.js` demo](https://graphiql-test.netlify.com/dev) - development build is nice for react inspector, debugging, etc
3. [bundle analyzer for graphiql.min.js](https://graphiql-test.netlify.com/analyzer)

## Examples

- [`Unpkg (CDN)`](../../examples/graphiql-cdn/) - a single html file using cdn assets and a script tag
- [`Webpack`](../../examples/graphiql-webpack/) - a starter for webpack
- [`Create React App`](../../examples/graphiql-create-react-app) - an example using [Create React App](https://create-react-app.dev/)
- [`Parcel`](../../examples/graphiql-parcel) - an example using [Parcel](https://parceljs.org/)
- `Rollup` - TODO

## Getting started

### Modules

You can use the `graphiql` module, however bear in mind that `react` `react-dom` and `graphql` will all need to be present already for it to work, as they are `peerDependencies`

With `npm`:

```
npm install --save graphiql react react-dom graphql
```

Alternatively, if you are using [`yarn`](https://yarnpkg.com/):

```
yarn add graphiql react react-dom graphql
```

### UMD

With `unpkg`/`jsdelivr`, etc:

```html
<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

Build for the web with [webpack](https://webpack.js.org/) or [browserify](http://browserify.org/), or use the pre-bundled `graphiql.js` file. See the [cdn example](../examples/graphiql-cdn/) in the git repository to see how to use the pre-bundled file, or see the [webpack example](../examples/graphiql-webpack) to see how to bundle an application using the `GraphiQL` component.

### Usage: NPM module

**Note**: If you are having webpack issues or questions about webpack, make sure you've cross-referenced your webpack configuration with our own [webpack example](../examples/graphiql-webpack) first. f you are having webpack issues or questions about webpack, make sure you've cross-referenced your webpack configuration with our own [webpack example](../examples/graphiql-webpack) first. We now have tests in CI that ensure this always builds, and we ensure it works end-to-end with every publish.

Using another GraphQL service? Here's how to get GraphiQL set up:

GraphiQL provides a React component responsible for rendering the UI, which should be provided with a required `fetcher function for executing GraphQL operations against your schema.

For HTTP transport implementations, we recommend using the [fetch](https://fetch.spec.whatwg.org/) standard API, but you can use anything that matches [the type signature](https://graphiql-test.netlify.app/typedoc/modules/graphiql-toolkit.html#fetcher), including async iterables and observables.

You can also install `@graphiql/create-fetcher` to make it easier to create a simple fetcher for conventional http and websockets transports.

```js
import React from 'react';
import ReactDOM from 'react-dom';

import GraphiQL from 'graphiql';
import { createGraphiQLFetcher } from '@graphiql/toolkit';

const fetcher = createGraphiQLFetcher({
  url: window.location.origin + '/graphql',
});

ReactDOM.render(
  <GraphiQL fetcher={fetcher} editorTheme={'dracula'} />,
  document.body,
);
```

Read more about using [`createGraphiQLFetcher`](https://github.com/graphql/graphiql/tree/main/packages/graphiql-toolkit/docs/create-fetcher.md) in the readme to learn how to add headers and more.

### Usage: UMD Bundle over CDN (Unpkg, JSDelivr, etc)

Don't forget to include the CSS file on the page! If you're using `npm` or `yarn`, you can find it in `node_modules/graphiql/graphiql.css`, or you can download it from the [releases page](https://github.com/graphql/graphiql/releases).

For an example of setting up a GraphiQL, check out the [example](../../examples/graphiql-cdn/) in this repository which also includes a few useful features highlighting GraphiQL's API.

The most minimal way to set up GraphiQL is a single index.html file:

```html
<html>
  <head>
    <title>Simple GraphiQL Example</title>
    <link href="https://unpkg.com/graphiql/graphiql.min.css" rel="stylesheet" />
  </head>
  <body style="margin: 0;">
    <div id="graphiql" style="height: 100vh;"></div>

    <script
      crossorigin
      src="https://unpkg.com/react/umd/react.production.min.js"
    ></script>
    <script
      crossorigin
      src="https://unpkg.com/react-dom/umd/react-dom.production.min.js"
    ></script>
    <script
      crossorigin
      src="https://unpkg.com/graphiql/graphiql.min.js"
    ></script>

    <script>
      const fetcher = GraphiQL.createFetcher('https://my/graphql');

      ReactDOM.render(
        React.createElement(GraphiQL, { fetcher: fetcher }),
        document.getElementById('graphiql'),
      );
    </script>
  </body>
</html>
```

**Notes**:

- the inlined styles are important for ensuring GraphiQL is visible and fills the canvas.
- using `React.createElement` directly is belaborous, so follow the webpack instructions above for more highly customized implementation
- we can use [`GraphiQL.createFetcher`](https://github.com/graphql/graphiql/tree/main/packages/graphiql-toolkit/docs/create-fetcher.md) in the UMD bundle only, so that it can be tree shaken out for modules

### GraphiQL for my GraphQL Service/HTTP Server/Etc

You may be using a runtime that already provides graphiql, or that provides it via a middleware. For example, we support [`express-graphql`](https://github.com/graphql/express-graphql)!

I would suggest a search for "graphiql <my runtime>" such as "graphiql express", "graphiql absinthe", etc to learn a potentially simpler route to setup for your environment. There are many npm packages, ruby gems, java utilities for deploying graphiql.

Here are some example searches:

- https://www.npmjs.com/search?q=graphiql - ~117 hits
- https://pypi.org/search/?q=graphiql - ~33 hits
- https://search.maven.org/search?q=graphiql - ~15 hits
- https://rubygems.org/search?utf8=%E2%9C%93&query=graphiql - ~6 hits
- https://godoc.org/?q=graphiql - ~12 hits
- https://packagist.org/?query=%22graphiql%22 - ~5 hits
- https://crates.io/search?q=graphiql - ~2 hits

This doesn't include runtimes or libraries where GraphiQL is used but isn't referenced in the package registry search entry.

## Customize

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

### Props

`fetcher` is the only required prop for `<GraphiQL />`.

For more details on props, see the [API Docs](https://graphiql-test.netlify.app/typedoc/modules/graphiql.html#graphiqlprops)

### Applying an Editor Theme

In order to theme the editor portions of the interface, you can supply a `editorTheme` prop. You'll also need to load the appropriate CSS for the theme (similar to loading the CSS for this project). [See the themes available here](https://codemirror.net/demo/theme.html).

```js
// In your html
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/codemirror/5.23.0/theme/solarized.css" />

// In your GraphiQL JSX
<GraphiQL
  editorTheme="solarized light"
/>
```
