graphql-modeler
Advanced tools
A GraphQL Voyager fork with schema editing capabilities, designed as a drop-in replacement for GraphQL Voyager.
A few notes: this is a work in progress and perhaps will never be finished or maintained (the fork is used in an internal project). There are some changes that you may not be OK with (some bits of text changed, required React version is >=16.8 because of hooks, etc.).
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!
GraphQL Voyager exports Voyager React component and helper init function. If used without
module system it is exported as GraphQLVoyager global variable.
Voyager component accepts the following properties:
introspection [object or function: (query: string) => Promise] - the server introspection response. If function is provided GraphQL Voyager will pass introspection query as a first function parameter. Function should return Promise which resolves to introspection response object.displayOptions (optional)
displayOptions.skipRelay [boolean, default true] - skip relay-related entitiesdisplayOptions.skipDeprecated [boolean, default true] - 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, default false] - sort fields on graph by alphabetdisplayOptions.showLeafFields [boolean, default true] - show all scalars and enumsdisplayOptions.hideRoot [boolean, default false] - hide the root typehideDocs [boolean, default false] - hide the docs sidebarhideSettings [boolean, default false] - hide settings panelworkerURI [string] (optional) - absolute or relative path to Voyager web worker. By default it will try to load it from voyager.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 in utils/index.tsinit functionThe signature of the init function:
(hostElement: HTMLElement, options: object) => void
hostElement - parent elementoptions - is the JS object with properties of Voyager componentYou can get GraphQL Voyager bundle from the following places:
dist folder of the npm package graphql-voyagerImportant: for the latest two options make sure to copy voyager.worker.js to the same
folder as voyager.min.js.

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'}
// ...
/>
Graphql Voyager has middleware for the next frameworks:
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{ Authorization: localStorage['Meteor.loginToken'] }import express from 'express';
import { express as voyagerMiddleware } from 'graphql-voyager/middleware';
const app = express();
app.use('/voyager', voyagerMiddleware({ endpointUrl: '/graphql' }));
app.listen(3001);
import hapi from 'hapi';
import { hapi as voyagerMiddleware } from 'graphql-voyager/middleware';
const server = new Hapi.Server({
port: 3001
});
const init = async () => {
await server.register({
plugin: voyagerMiddleware,
options: {
path: '/voyager',
endpointUrl: '/graphql'
}
});
await server.start();
};
init();
import hapi from 'hapi';
import { hapiLegacy as voyagerMiddleware } from 'graphql-voyager/middleware';
const server = new Hapi.Server();
server.connection({
port: 3001
});
server.register({
register: voyagerMiddleware,
options: {
path: '/voyager',
endpointUrl: '/graphql'
}
},() => server.start());
import Koa from 'koa';
import KoaRouter from 'koa-router';
import { koa as voyagerMiddleware } from 'graphql-voyager/middleware';
const app = new Koa();
const router = new KoaRouter();
router.all('/voyager', voyagerMiddleware({
endpointUrl: '/graphql'
}));
app.use(router.routes());
app.use(router.allowedMethods());
app.listen(3001);
This tool is inspired by graphql-visualizer project.
