Story

As a user I'm sometimes opening subscriptions to servers that may need to authenticate some form of credentials which could be dependant on other services

I want to be able to specify a longer timeout before the connection is closed while waiting for the ConnectionAck method

So that I don't fail to connect when authentication to the server takes longer.

Acceptance criteria

  • client is able to set the connection timeout during client creation

You can indeed do that already, but on the server side since clients can't (and should not) make that decision. Check out the connectionInitWaitTimeout server option.

The client is making such a decision though, putting the server on the clock. See

graphql-ws/src/client.ts

Line 359 in 51e5459

const tooLong = setTimeout(() => {

In my case I'm using the PHP WebSocket Server implementation: https://github.com/goalgorilla/graphql-php-ws The client is sending the init message quickly enough. However, the server needs to go to an external service that often takes about 6 seconds to come back with a reply. This means that the client terminates the connection just as the server is ready to acknowledge the connection.

I can not acknowledge the connection sooner because the client is unauthenticated, so acknowledging the connection during the authentication would incorrectly signal to the client that they're ready to start subscriptions (because unauthenticated subscriptions are invalid in the application).

Ahh, yes! You are absolutely right. Even though, thats not a ConnectionInit waiter, it was actually thought of as safeguard that prevents never-ending promises. But, I think we dont even need it...

Anyways, thanks for clarifying and brining it up! A PR coming very soon.

Oh and, awesome work with the PHP WS server! Lovely to see other people implementing the Protocol in various languages. 😄

* Reduce runtime prototype traversal for hasOwnProperty ([enisdenjo#52](https://github.com/ilijaNL/graphql-ws/issues/52)) ([1bb9218](1bb9218))

### Reverts

* Revert "refactor: emit client connect in next tick during testing" ([c10d0bf](c10d0bf))

### BREAKING CHANGES

* Because of the Protocol's strictness, an instant connection termination will happen whenever an invalid message is identified; meaning, all previous implementations will fail when receiving the new subprotocol ping/pong messages.

**Beware,** the client will NOT ping the server by default. Please make sure to upgrade your stack in order to support the new ping/pong message types.

A simple recipe showcasing a client that times out if no pong is received and measures latency, looks like this:
```js
import { createClient } from 'graphql-ws';

let activeSocket,
  timedOut,
  pingSentAt = 0,
  latency = 0;
createClient({
  url: 'ws://i.time.out:4000/and-measure/latency',
  keepAlive: 10_000, // ping server every 10 seconds
  on: {
    connected: (socket) => (activeSocket = socket),
    ping: (received) => {
      if (!received /* sent */) {
        pingSentAt = Date.now();
        timedOut = setTimeout(() => {
          if (activeSocket.readyState === WebSocket.OPEN)
            activeSocket.close(4408, 'Request Timeout');
        }, 5_000); // wait 5 seconds for the pong and then close the connection
      }
    },
    pong: (received) => {
      if (received) {
        latency = Date.now() - pingSentAt;
        clearTimeout(timedOut); // pong is received, clear connection close timeout
      }
    },
  },
});
```
* **uWebSockets:** The deprecated uWebSockets `request` context extra field has been dropped because it is stack allocated and cannot be used ouside the internal `upgrade` callback.
* **client:** Client `keepAlive` option has been renamed to `lazyCloseTimeout` in order to eliminate ambiguity with the client to server pings keep-alive option.
* **server:** The return function of `server.opened` (`closed`) now requires the close event code and reason for reporting to the `onDisconnect` callback.
* **server:** The `Context.subscriptions` record value can be either an `AsyncIterator` or a `Promise`.
* **client:** Client `retryTimeout` option has been replaced with the new `retryWait`.

`retryWait` allows you to control the retry timeout strategy by resolving the returned promise when ready. The default implements the randomised exponential backoff like so:
```ts
// this is the default
const retryWait = async function randomisedExponentialBackoff(retries: number) {
  let retryDelay = 1000; // start with 1s delay
  for (let i = 0; i < retries; i++) {
    retryDelay *= 2; // square `retries` times
  }
  await new Promise((resolve) =>
    setTimeout(
      // resolve pending promise with added random timeout from 300ms to 3s
      resolve,
      retryDelay + Math.floor(Math.random() * (3000 - 300) + 300),
    ),
  );
};
```
* **server:** You now "make" a ready-to-use server that can be used with _any_ WebSocket implementation!

Summary of breaking changes:
- No more `keepAlive`. The user should provide its own keep-alive implementation. _(I highly recommend [WebSocket Ping and Pongs](https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API/Writing_WebSocket_servers#Pings_and_Pongs_The_Heartbeat_of_WebSockets))_
- No more HTTP `request` in the server context.
- No more WebSocket in the server context (you're the one that creates it).
- You use your own WebSocket server
- Server exports only `makeServer` _(no more `createServer`)_

### Benefits
- You're responsible for the server (_any_ optimisation or adjustment can be applied)
- Any WebSocket server can be used (or even mocked if necessary)
- You control the disposal of the server (close or transfer clients however you wish)
- New `extra` field in the `Context` for storing custom values useful for callbacks
- Full control of authentication flow
- Full control over error handling
- True zero-dependency

### Migrating from v1

**Only the server has to be migrated.** Since this release allows you to use your favourite WebSocket library (or your own implementation), using [ws](https://github.com/websockets/ws) is just one way of using `graphql-ws`. This is how to use the implementation shipped with the lib:

```ts
/**
 * ❌ instead of the lib creating a WebSocket server internally with the provided arguments
 */
import https from 'https';
import { createServer } from 'graphql-ws';

const server = https.createServer(...);

createServer(
  {
    onConnect(ctx) {
      // were previously directly on the context
      ctx.request as IncomingRequest
      ctx.socket as WebSocket
    },
    ...rest,
  },
  {
    server,
    path: '/graphql',
  },
);

/**
 * ✅ you have to supply the server yourself
 */
import https from 'https';
import ws from 'ws'; // yarn add ws
import { useServer } from 'graphql-ws/lib/use/ws'; // notice the import path

const server = https.createServer(...);
const wsServer = new ws.Server({
  server,
  path: '/graphql',
});

useServer(
  {
    onConnect(ctx) {
      // are now in the `extra` field
      ctx.extra.request as IncomingRequest
      ctx.extra.socket as WebSocket
    },
    ...rest,
  },
  wsServer,
  // optional keepAlive with ping pongs (defaults to 12 seconds)
);
```
* This lib is no longer compatible with [`subscriptions-transport-ws`](https://github.com/apollographql/subscriptions-transport-ws). It follows a redesigned transport protocol aiming to improve security, stability and reduce ambiguity.
