This is the Express and Connect integration of GraphQL Server. Apollo Server is a community-maintained open-source GraphQL server that works with many Node.js HTTP server frameworks. [Read the docs](https://www.apollographql.com/docs/apollo-server/). [Read the CHANGELOG.](https://github.com/apollographql/apollo-server/blob/master/CHANGELOG.md)
|
|
|
|
```sh
|
|
npm install apollo-server-express
|
|
```
|
|
|
|
## Express
|
|
|
|
```js
|
|
const express = require('express');
|
|
const { ApolloServer, gql } = require('apollo-server-express');
|
|
|
|
// Construct a schema, using GraphQL schema language
|
|
const typeDefs = gql`
|
|
type Query {
|
|
hello: String
|
|
}
|
|
`;
|
|
|
|
// Provide resolver functions for your schema fields
|
|
const resolvers = {
|
|
Query: {
|
|
hello: () => 'Hello world!',
|
|
},
|
|
};
|
|
|
|
const server = new ApolloServer({ typeDefs, resolvers });
|
|
|
|
const app = express();
|
|
server.applyMiddleware({ app });
|
|
|
|
app.listen({ port: 4000 }, () =>
|
|
console.log(`🚀 Server ready at http://localhost:4000${server.graphqlPath}`)
|
|
);
|
|
```
|
|
|
|
## Connect
|
|
|
|
```js
|
|
const connect = require('connect');
|
|
const { ApolloServer, gql } = require('apollo-server-express');
|
|
const query = require('qs-middleware');
|
|
|
|
// Construct a schema, using GraphQL schema language
|
|
const typeDefs = gql`
|
|
type Query {
|
|
hello: String
|
|
}
|
|
`;
|
|
|
|
// Provide resolver functions for your schema fields
|
|
const resolvers = {
|
|
Query: {
|
|
hello: () => 'Hello world!',
|
|
},
|
|
};
|
|
|
|
const server = new ApolloServer({ typeDefs, resolvers });
|
|
|
|
const app = connect();
|
|
const path = '/graphql';
|
|
|
|
server.use(query());
|
|
server.applyMiddleware({ app, path });
|
|
|
|
app.listen({ port: 4000 }, () =>
|
|
console.log(`🚀 Server ready at http://localhost:4000${server.graphqlPath}`)
|
|
);
|
|
```
|
|
|
|
> Note; `qs-middleware` is only required if running outside of Meteor

## Principles
|
|
|
|
GraphQL Server is built with the following principles in mind:
|
|
|
|
* **By the community, for the community**: GraphQL Server's development is driven by the needs of developers
|
|
* **Simplicity**: by keeping things simple, GraphQL Server is easier to use, easier to contribute to, and more secure
|
|
* **Performance**: GraphQL Server is well-tested and production-ready - no modifications needed
|
|
