OnSign Instructions

Because this project is kind of a mess (in many ways), I'm leaving the basic requirements to build the project here for future usages.

Requirements:

• Python 2.7 (you can use pyenv if on MacOS)
• Node 18 (you can use nvm)
• Yarn 1.x.x (aka legacy version)

After installing all the requirements, go to packages/graphql-playground-react and run:

yarn
yarn build

If everything went right, packages/graphql-playground-react/build/static/js/middleware.js will have the code we want to copy to our OnSign-GraphQLPlayground.js on the main repo.

General Instructions

FAQ

How is this different from GraphiQL?

GraphQL Playground uses components of GraphiQL under the hood but is meant as a more powerful GraphQL IDE enabling better (local) development workflows. Compared to GraphiQL, the GraphQL Playground ships with the following additional features:

• Interactive, multi-column schema documentation
• Automatic schema reloading
• Support for GraphQL Subscriptions
• Query history
• Configuration of HTTP headers
• Tabs

See the following question for more additonal features.

What's the difference between the desktop app and the web version?

The desktop app is the same as the web version but includes these additional features:

• Partial support for graphql-config enabling features like multi-environment setups (no support for sending HTTP headers).
• Double click on *.graphql files.

How does GraphQL Bin work?

You can easily share your Playgrounds with others by clicking on the "Share" button and sharing the generated link. You can think about GraphQL Bin like Pastebin for your GraphQL queries including the context (endpoint, HTTP headers, open tabs etc).

You can also find the announcement blog post here.

Settings

In the top right corner of the Playground window you can click on the settings icon. These are the settings currently available:

{
  'editor.cursorShape': 'line', // possible values: 'line', 'block', 'underline'
  'editor.fontFamily': `'Source Code Pro', 'Consolas', 'Inconsolata', 'Droid Sans Mono', 'Monaco', monospace`,
  'editor.fontSize': 14,
  'editor.reuseHeaders': true, // new tab reuses headers from last tab
  'editor.theme': 'dark', // possible values: 'dark', 'light'
  'general.betaUpdates': false,
  'prettier.printWidth': 80,
  'prettier.tabWidth': 2,
  'prettier.useTabs': false,
  'request.credentials': 'omit', // possible values: 'omit', 'include', 'same-origin'
  'schema.polling.enable': true, // enables automatic schema polling
  'schema.polling.endpointFilter': '*localhost*', // endpoint filter for schema polling
  'schema.polling.interval': 2000, // schema polling interval in ms
  'schema.disableComments': boolean,
  'tracing.hideTracingResponse': true,
}

Usage

Properties

The React component <Playground /> and all middlewares expose the following options:

• props (Middlewares & React Component)
  • endpoint string - the GraphQL endpoint url.
  • subscriptionEndpoint string - the GraphQL subscriptions endpoint url.
  • workspaceName string - in case you provide a GraphQL Config, you can name your workspace here
  • config string - the JSON of a GraphQL Config. See an example here
  • settings ISettings - Editor settings in json format as described here

interface ISettings {
  'editor.cursorShape': 'line' | 'block' | 'underline'
  'editor.fontFamily': string
  'editor.fontSize': number
  'editor.reuseHeaders': boolean
  'editor.theme': 'dark' | 'light'
  'general.betaUpdates': boolean
  'prettier.printWidth': number
  'prettier.tabWidth': number
  'prettier.useTabs': boolean
  'request.credentials': 'omit' | 'include' | 'same-origin'
  'schema.polling.enable': boolean
  'schema.polling.endpointFilter': string
  'schema.polling.interval': number
  'schema.disableComments': boolean
  'tracing.hideTracingResponse': boolean
}

• schema IntrospectionResult - The result of an introspection query (an object of this form: {__schema: {...}}) The playground automatically fetches the schema from the endpoint. This is only needed when you want to override the schema.
• tabs Tab[] - An array of tabs to inject. Note: When using this feature, tabs will be resetted each time the page is reloaded

interface Tab {
	endpoint: string
	query: string
	name?: string
	variables?: string
	responses?: string[]
	headers?: { [key: string]: string }
}

In addition to this, the React app provides some more properties:

• props (React Component)
• createApolloLink [(session: Session, subscriptionEndpoint?: string) => ApolloLink] - this is the equivalent to the fetcher of GraphiQL. For each query that is being executed, this function will be called

createApolloLink is only available in the React Component and not the middlewares, because the content must be serializable as it is being printed into a HTML template.

As HTML Page

If you simply want to render the Playground HTML on your own, for example when implementing a GraphQL Server, there are 2 options for you:

1. The bare minimum HTML needed to render the Playground
2. The Playground HTML with full loading animation

Note: In case you do not want to serve assets from a CDN (like jsDelivr) and instead use a local copy, you will need to install graphql-playground-react from npm, and then replace all instances of //cdn.jsdelivr.net/npm with ./node_modules. An example can be found here

As React Component

Install

yarn add graphql-playground-react

Use

GraphQL Playground provides a React component responsible for rendering the UI and Session management. There are 3 dependencies needed in order to run the graphql-playground-react React component.

1. Open Sans and Source Code Pro fonts
2. Rendering the <Playground /> component

The GraphQL Playground requires React 16.

Including Fonts (1.)

<link
	href="https://fonts.googleapis.com/css?family=Open+Sans:300,400,600,700|Source+Code+Pro:400,700"
	rel="stylesheet"
/>

Including stylesheet and the component (2., 3.)

import React from 'react'
import ReactDOM from 'react-dom'
import { Provider } from 'react-redux'
import { Playground, store } from 'graphql-playground-react'

ReactDOM.render(
	<Provider store={store}>
		<Playground endpoint="https://api.graph.cool/simple/v1/swapi" />
	</Provider>,
	document.body,
)

As Server Middleware

Install

# Pick the one that matches your server framework
yarn add graphql-playground-middleware-express  # for Express or Connect
yarn add graphql-playground-middleware-hapi
yarn add graphql-playground-middleware-koa
yarn add graphql-playground-middleware-lambda

Usage with example

We have a full example for each of the frameworks below:

• Express: See packages/graphql-playground-middleware-express/examples/basic

• Hapi: See packages/graphql-playground-middleware-hapi

• Koa: See packages/graphql-playground-middleware-koa

• Lambda (as serverless handler): See serverless-graphql-apollo or a quick example below.

As serverless handler

Install

yarn add graphql-playground-middleware-lambda

Usage

handler.js

import lambdaPlayground from 'graphql-playground-middleware-lambda'
// or using require()
// const lambdaPlayground = require('graphql-playground-middleware-lambda').default

exports.graphqlHandler = function graphqlHandler(event, context, callback) {
	function callbackFilter(error, output) {
		// eslint-disable-next-line no-param-reassign
		output.headers['Access-Control-Allow-Origin'] = '*'
		callback(error, output)
	}

	const handler = graphqlLambda({ schema: myGraphQLSchema })
	return handler(event, context, callbackFilter)
}

exports.playgroundHandler = lambdaPlayground({
	endpoint: '/dev/graphql',
})

serverless.yml

functions:
  graphql:
    handler: handler.graphqlHandler
    events:
      - http:
          path: graphql
          method: post
          cors: true
  playground:
    handler: handler.playgroundHandler
    events:
      - http:
          path: playground
          method: get
          cors: true

Development

$ cd packages/graphql-playground-react
$ yarn
$ yarn start

Open localhost:3000/localDev.html?endpoint=https://api.graph.cool/simple/v1/swapi for local development!

Custom Theme

From [email protected] on you can provide a codeTheme property to the React Component to customize your color theme. These are the available options:

export interface EditorColours {
	property: string
	comment: string
	punctuation: string
	keyword: string
	def: string
	qualifier: string
	attribute: string
	number: string
	string: string
	builtin: string
	string2: string
	variable: string
	meta: string
	atom: string
	ws: string
	selection: string
	cursorColor: string
	editorBackground: string
	resultBackground: string
	leftDrawerBackground: string
	rightDrawerBackground: string
}
