Starting with the server, create a new simple PubSub instance. We will later use this PubSub to publish and subscribe to data changes. Now, create SubscriptionServer instance, with your GraphQL schemaexecute and subscribe from graphql-js package :. Please refer to graphql-subscriptions documentation for how to create your GraphQL subscriptions, and how to publish data.

When using this package for client side, you can choose either use HTTP request for Queries and Mutation and use the WebSocket for subscriptions only, or create a full transport that handles all type of GraphQL operations over the socket. To start with a full WebSocket transport, that handles all types of GraphQL operations, import and create an instance of SubscriptionClient. Then, create your ApolloClient instance and use the SubscriptionsClient instance as network interface:. Now, when you want to use subscriptions in client side, use your ApolloClient instance, with subscribe or query subscribeToMore :.

If you are using the latest version of graphql-server flavors graphql-server-expressgraphql-server-koaetc Make sure to specify subscriptionsEndpoint in GraphiQL configuration, and that's it! Can be used for integration testing with in-memory WebSocket implementation.

The docs describe authentication on websockets as providing the token in connectionParams when creating the WsLink initially.

But it is unclear how to change the token later and reinitialize connection if the user logs out and logs in again possibly with a different token.

Oh wait, this isn't called after the first time Maybe concat with another middleware that puts an authentication object on the response that you can parse with onOperation server side? Since the new WebSocketLink is still creating an instance of subscriptions-transport-wsI am manually applying my middleware to the Subscription Transport client, rather than to the WebSocketLink.

Any values that you add to the options object are available in the onOperation callback on the server side. After login or logout I'm doing:. Ideally this would support a promise returning function as well so if we have to async fetch the token we can.

But because of the async i added, it keep sending undefined to the server. I have an issue with this? However, the connect API for the subscription client is marked private and ideally should not be used. I tried doing a subscriptionClient. The only thing that is working right now is:. Any clean new ideas on this? Love to have a solution here. I create my apollo link on load but once my user logs in id really like to update the token being sent in the context.

The context is created on every operation and we simply look up the user dynamically. This helped to me comment. Or is there a way to send a different Authorization header on each request other than re-opening another ws channel?GitHub is home to over 50 million developers working together to host and review code, manage projects, and build software together.

Have you tried connecting to Daphne directly to see if that works? I'd like to rule out the proxy setup if possible. Could you get the close code from the websocket object for me? That might help work out what the browser is seeing. It's event. Ok, as this problem got really un-logic; I created another server, deployed on it, and directly connecting works no problem!!

This can be used for authentication, persisted queries, dynamic uris, and other granular updates. HTTP Link takes an object with some options on it to customize the behavior of the link.

If your server supports it, the HTTP link can also send over metadata about the request in the extensions field. To enable this, pass includeExtensions as true. The options you can pass are outlined below:.

If you are running on react-native, or modern browsers, this should be no problem. If you are targeting an environment without fetch such as older browsers or the server, you will need to pass your own fetch to the link through the options.

We recommend unfetch for older browsers and node-fetch for running in Node. It also supports the credentials field for defining credentials policy, uri for changing the endpoint dynamically, and fetchOptions to allow generic fetch overrides i.

These options will override the same key if passed when creating the the link. Note that if you set fetchOptions. This link also attaches the response from the fetch operation on the context as response so you can access it from within another link. The http link supports an advanced GraphQL feature called persisted queries. This allows you to not send the stringified query over the wire, but instead send some kind of identifier of the query.

To support this you need to attach the id somewhere to the extensions field and pass the following options to the context:. One way to use persisted queries is with apollo-link-persisted-queries and Apollo Engine.

apollo-link-ws

Apollo Client supports passing context separately for every query, so you can do things like pass a special header for a single query invocation if you need to. Server errors can occur in three different scenarios: parse, network and data errors. This list describes the scenarios that cause different errors:. Since many server implementations can return a valid GraphQL result on a server network error, the thrown Error object contains the parsed server result.GitHub is home to over 50 million developers working together to host and review code, manage projects, and build software together.

Just adding to this, the apollo-link-error lib also doesn't capture any websocket connection errors but the app i was working on needed to dispatch redux actions to inform the user of whether they were connected or not.

Thankfully, there are now hooks directly on subscriptionClient so i was able to build a redux middleware like this:. It takes some care because websocket clients can't really be reinstated like EventSource clients.

When the websocket close event fires, you can't restart it, you just have to call new WebSocket and put your onerror handler back on it. I still haven't released the server protocol, but maybe it'll provide some inspo?

The websocket connection is closed by checkMaxConnectTimeout before the timeout value defined in the client options is reached; which results in websocket subscriptions not being instantiated. I see the timeout is calculated by this. Is that what's fixed by ? I am actually not sure. After troubleshooting the issue, it seems like subscriptions-transport-ws will close the connection after only ms if it hasn't received a response from the server it uses Backoff, with a hard coded start of ms and a hard coded factor of 1.

It subsequently keeps trying to connect every few 's of ms and closes the connection before the handshake can happen. I might not be setting it up properly, my options are:. As a temporary fix to this issue, I run the following after the client's instantiation: subscriptionClient. Line in 0da I'm also having the same problem in 0. Is it an issue with the server or client?

You saved our lives. I second that. As a user, I will be interested in two timeouts separately: the connects especially the initial one, which I might treat specially, because it often means I'll have to tell user that the app is unavailableand the keep-alive.

Currently, not only they're clumped together under one timeout option, but also the connect is actually very frustratingly starting with ms and ramping up to the user setting rather slowly. Interestingly, if the delay is caused by network congestion, it will congest the network even more and the user will get his connection later.

Also notably, TCP protocol does have a built-in retransmission which works as early as during the handshakeso this userspace-code ramping up seems to be reinventing the wheel a bit I appreciate some apps and network setups might not like the OS defaults, but I don't think a general purpose library like this should take an opinionated approach that all users want this.

Please remove this ramping up, or at least make the default to not do it. Or at least pull this pr so users can do it themselves without brittle mangling of private members like the current workaround. Oh, guess you may not be using TypeScript? But even if I apply the workaround by casting to any the error still occurs. Same thing happening for me. Establishing the connection to my server seems to take a little bit longer than 1 second.

But as this "min" value is hardcoded it makes it worse because it tries and closes it many times. I was able to workaround it as others with client. On my side this problem occur only on Chrome, when react extension is enabled. CyrilSiman That has worked for me also. I wonder if it is due to a recent update to the React Extension as this problem only arose in the past week or so for me.

That arsanjea workaround worked for me too, what about the roadmap to fix this issue? Any idea why react-dev tools is causing this issue? I was able to verify that turning the extension off fixed the issue for me as well. Sometimes the client has to reconnect times for the connection to finally work.

OK, I have some information on what is driving this issue and it has something to do with the way async operations are run in JS.
