GraphQL Voyager
Represent any GraphQL API as an interactive graph. It's time to finally see the graph behind GraphQL. You can also explore number of public GraphQL APIs from our list.
With graphql-voyager you can visually explore your GraphQL API as an interactive graph. This is a great tool when designing or discussing your data model. It includes multiple example GraphQL schemas and also allows you to connect it to your own GraphQL endpoint. What are you waiting for, explore your API!
Live Demo
Features
- Quick navigation on graph
- Left panel which provides more detailed information about every type
- "Skip Relay" option that simplifies graph by removing Relay wrapper classes
- Ability to choose any type to be a root of the graph
Usage
GraphQL Voyager exports Voyager React component and helper init function. If used without
module system it is exported as GraphQLVoyager global variable.
Properties
Voyager component accepts the following properties:
introspection[objector function:(query: string) => Promise] - the server introspection response. Iffunctionis provided GraphQL Voyager will pass introspection query as a first function parameter. Function should returnPromisewhich resolves to introspection response object.displayOptions(optional)displayOptions.skipRelay[boolean, defaulttrue] - skip relay-related entitiesdisplayOptions.skipDeprecated[boolean, defaulttrue] - skip deprecated fields and entities that contain only deprecated fields.displayOptions.rootType[string] - name of the type to be used as a rootdisplayOptions.sortByAlphabet[boolean, defaultfalse] - sort fields on graph by alphabetdisplayOptions.showLeafFields[boolean, defaulttrue] - show all scalars and enumsdisplayOptions.hideRoot[boolean, defaultfalse] - hide the root type
hideDocs[boolean, defaultfalse] - hide the docs sidebarhideSettings[boolean, defaultfalse] - hide settings panelworkerURI[string] (optional) - absolute or relative path to Voyager web worker. By default it will try to load it fromvoyager.worker.js.loadWorker[function:(path: string, relative: boolean) => Promise<Worker>] (optional) - If provided GraphQL Voyager will use this function to load the worker. By default it will use the internal callback inutils/index.ts
init function
The signature of the init function:
(hostElement: HTMLElement, options: object) => voidhostElement- parent elementoptions- is the JS object with properties ofVoyagercomponent
Using pre-bundled version
You can get GraphQL Voyager bundle from the following places:
- jsDelivr CDN
- some exact version - https://cdn.jsdelivr.net/npm/graphql-voyager/v1.0.0-rc.15/voyager.min.js
- latest version - https://cdn.jsdelivr.net/npm/graphql-voyager/dist/voyager.min.js
- from
distfolder of the npm packagegraphql-voyager
Important: for the latest two options make sure to copy voyager.worker.js to the same
folder as voyager.min.js.

});
</script>

</html>Using as a dependency
You can install lib using npm or yarn:
npm i --save graphql-voyager
yarn add graphql-voyager
And then use it:
import * as React from 'react';
import * as ReactDOM from 'react-dom';
import { Voyager } from 'graphql-voyager';
import fetch from 'isomorphic-fetch';
function introspectionProvider(query) {
return fetch(window.location.origin + '/graphql', {
method: 'post',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify({ query: query }),
}).then((response) => response.json());
}
ReactDOM.render(
<Voyager introspection={introspectionProvider} />,
document.getElementById('voyager'),
);Build for the web with webpack (example) or browserify
Important: make sure to copy voyager.worker.js from node_modules/graphql-voyager/dist to the same folder as your main bundle or use workerURI property to specify other path.
NOTE if you use it with create-react-app, copy worker file to public folder and use workerURI property like this:
<Voyager
// ...
workerURI={process.env.PUBLIC_URL + '/voyager.worker.js'}
// ...
/>Middleware
Graphql Voyager has middleware for the next frameworks:
Properties
Middleware supports the following properties:
endpointUrl[string] - the GraphQL endpoint url.displayOptions[object] - same as hereheadersJS[string, default"{}"] - object of headers serialized in string to be used on endpoint url
Note: You can also use any JS expression which results in an object with header names as keys and strings as values e.g.{ Authorization: localStorage['Meteor.loginToken'] }
