Advanced tools
This is the Koa integration of Apollo Server. Apollo Server is a community-maintained open-source Apollo Server that works with all Node.js HTTP server frameworks: Express, Connect, Hapi, Koa and Restify. Read the docs.
npm install apollo-server-koa
import koa from 'koa'; // koa@2
import koaRouter from 'koa-router';
import koaBody from 'koa-bodyparser';
import { graphqlKoa } from 'apollo-server-koa';
const app = new koa();
const router = new koaRouter();
const PORT = 3000;
// koaBody is needed just for POST.
app.use(koaBody());
router.post('/graphql', graphqlKoa({ schema: myGraphQLSchema }));
router.get('/graphql', graphqlKoa({ schema: myGraphQLSchema }));
app.use(router.routes());
app.use(router.allowedMethods());
app.listen(PORT);
You can also use apollo-server-koa
for hosting the GraphiQL in-browser IDE. Note the difference between graphqlKoa
and graphiqlKoa
.
import { graphiqlKoa } from 'apollo-server-koa';
// Setup the /graphiql route to show the GraphiQL UI
router.get('/graphiql', graphiqlKoa({
endpointURL: '/graphql' // a POST endpoint that GraphiQL will make the actual requests to
}));
In case your GraphQL endpoint is protected via authentication, or if you need to pass other custom headers in the request that GraphiQL makes, you can use the passHeader
option – a string that will be added to the request header object.
For example:
import { graphiqlKoa } from 'apollo-server-koa';
router.get('/graphiql', graphiqlKoa({
endpointURL: '/graphql',
passHeader: `'Authorization': 'Bearer lorem ipsum'`
}));
Apollo Server is built with the following principles in mind:
