guys, I have a problem when I want to use a Subscription I'm facing this issue I don't find a solution in any place, I'm a GQL user and i decide to use Subscription to make real-time website but I'm facing a a this issue , hare is code
I'm trying to show apollo docs but I'm facing another issue(graphql doesn't find my resolver), so I try to use this pace of code in my mind it's work but the issue is it says Unable to connect wss://localhost:4001 also I'm trying to use Unable to connect wss://localhost:4001/graphql and Unable to connect wss://localhost:4001/subscription, also i try this three way with using ws
// my resolver
const somethingChanged = () => {
// subscribe: () => {
console.log("subscribe")
pubsub.asyncIterator(SOMETHING_CHANGED_TOPIC)
// }
}
const makeId = () => {
// make id generator 36 symbols
let id = Math.random().toString(36).split(".")[1]
pubsub.publish(SOMETHING_CHANGED_TOPIC, {
somethingChanged: {
id,
},
})
return id
}
const resolvers = {
Subscription: {
somethingChanged,
},
Query: {
hello: () => "Hello world!",
},
Mutation: {
makeId,
},
}
// app.ts
import { createServer } from "http"
import express from "express"
import { ApolloServer, gql } from "apollo-server-express"
import { typeDefs } from "./graphql/schema"
import "colors"
import resolvers from "./graphql/root"
import connect from "./db/connect"
import { PubSub } from "graphql-subscriptions"
const SOMETHING_CHANGED_TOPIC = "something_changed"
require("dotenv").config()
export const pubsub = new PubSub()
// 1 creating one function for app
const startServer = async () => {
// 2 // declaring app as express
const app = express()
const httpServer = createServer(app)
setInterval(() => {
console.log(`Server was work ${Math.random().toString()}`.green)
}, 2000)
// middleware's
connect()
// 5
const apolloServer = new ApolloServer({
typeDefs,
resolvers,
context: ({ req }) => req,
})
// 6
await apolloServer.start()
// 7
apolloServer.applyMiddleware({
app,
path: "/graphql",
})
// 8
httpServer.listen({ port: process.env.PORT || 4001 }, () =>
console.log(
`Server listening on localhost:4001${apolloServer.graphqlPath}`.blue
)
)
}
startServer()
I just want to test in apollo explorer but it doesn't work
