我有一个使用GraphQLServer的工作项目,它从端口4000服务我的react应用程序,并在端口5000上监听socket-io。
我正尝试部署到heroku,因此我需要它们位于同一端口上(process.env.PORT),但是我不知道如何使用GraphQLServer做到这一点。
This is how to do it with express + socket-io
This is the start script for GraphQLServer
Gist with my current code is here
相关代码:
import server from './server';
import express from 'express';
import path from 'path';
const http = require('http').Server(server.express);
const io = require('socket.io')(http);
require('./socket')(io);
server.express.use(express.static(path.join(__dirname, '../../client/build')));
server.express.get('/*', function(req, res) {
res.sendFile(path.join(__dirname, '../../client/build', 'index.html'));
});
// Socket-io listener
http.listen({
port: process.env.PORT || 5000
}, () =>
console.log('listening on port ' + process.env.PORT || 5000)
);
// GraphQL and app listener
server.start({
cors: {
credentials: true,
origin: '/'
}
// port: process.env.PORT || 4000
},
() => {
console.log('The server is up!');
}
);

没有从graphql-yoga的开发人员那里得到任何输入,因此在prisma slack上被询问,建议使用apollo-server-express。
我注意到切换到ApolloServer的主要变化是:
{ req, res }
而不是{ request, response }
typeDefs: importSchema('./src/schema.graphql')
首先,我为socket-io创建一个快速应用程序和httpServer,并告诉io监听使用该应用程序实例化的httpServer :
const app = express();
const httpServer = require('http').createServer(app);
const io = require('socket.io')(httpServer);
require('./socket')(io); // my io.on('connection', socket => {}) function taking io as param
io.listen(httpServer);
然后我应用所有中间件并使用应用设置路由:
if (process.env.NODE_ENV === 'production') {
app.use(express.static(path.join(__dirname, '../../client/build')));
app.get('/', function(req, res) {
res.sendFile(path.join(__dirname, '../../client/build', 'index.html'));
});
} else {
app.get('/', (req, res) => {
res.sendFile(path.join(__dirname, '../../client/public', 'index.html'));
});
}
app.use(cookieParser());
app.use((req, res, next) => {
if (!req.cookies || !req.cookies.token) {
return next();
}
const { token } = req.cookies;
if (token) {
console.log(process.env.PORT);
const { userId } = jwt.verify(token, process.env.JWT_SECRET);
// Put the userId onto the req for future requests to access
req.userId = userId;
}
next();
});
最后(使用ApolloServer 2),我将应用程序作为中间件应用到ApolloServer,并告诉httpServer监听:
import server from './server' // my ApolloServer
server.applyMiddleware({
app,
path: '/graphql',
cors: {
credentials: true,
origin: process.env.DOMAIN_FULL + ':' + process.env.PORT || '3000'
}
});
httpServer.listen({
port: process.env.PORT || 4000
},
() => console.log(`Server is running on ${server.graphqlPath}`)
);
请确保您使用的是不带参数的io()实例化客户端,并且您的ApolloClient uri为'/graphql'
