graphql-transport-electron

Why

In case you want to run a graphql server inside of the Electron main process (for instance if you are building a decentralized application), you need to have the client (renderer process) and server (main process) communicate through Electron IPC.

This project provides a very lightweight client and server interface for Electron IPC based on Apollo.

While its primary use-case is to enable a self-sustained and isolated graphql server inside of the Electron main process, you can connect the server interface to any ApolloLink instance. This means that you could also connect it with a HttpLink / WsLink that forwards your queries to a hosted graphql server outside of Electron.

Installation

# With yarn
yarn add graphql-transport-electron

# With npm
npm install graphql-transport-electron

Usage example

Main process

import { ipcMain } from 'electron';
// NOTE: The library ships with a fork of apollo-link-schema that also supports subscriptions.
import { createSchemaLink, createIpcExecutor } from 'graphql-transport-electron';
import schema from './my-graphql-schema';

// NOTE: This also works with any other apollo link (e.g. HttpLink from apollo-link).
const link = createSchemaLink({ schema });
createIpcExecutor({link, ipc: ipcMain });

Renderer process

import { ApolloClient } from 'apollo-client';
import { InMemoryCache } from 'apollo-cache-inmemory';
import { ipcRenderer } from 'electron';
import { createIpcLink } from 'graphql-transport-electron';

const link = createIpcLink({ ipc: ipcRenderer });
const client = new ApolloClient({
  cache: new InMemoryCache(),
  link,
});
