The HTTP/2+ protocol itself allows for virtually unlimited connections over the multiplex, but browsers generally limit to ~100. Since this isn't well documented, I've written a demonstration that shows that connections over 100 don't connect (tested in both Firefox and Chrome).

To run:

If you pass an array in place of an input object, an error is raised for each individual field that doesn't match, plus each "extra key" the array has (i.e. numeric indicies).

mkdir demo
cd demo
yarn add graphql @graphql-tools/schema
node repro.mjs

Expected result: one error (user is not an object)

GraphQLConf Working Group Sessions

On Tuesday of GraphQLConf this year we can use up to three sessions for WG purposes. Even if we just get our regular WG attendees in the room and discuss our regular topics face to face I think that would be beneficial. However, it seems like a great opportunity to interact with the wider audience and solicit feedback on our plans, use-cases, etc.

I'd love to know how you think the day should go; and we need to have a plan by the end of the first week in April — please chime in!

Key information:

• Conference days:
• Mon 8th — regular keynotes and conference tracks

Hosting a GraphQL Local? Here are some things to consider! If you need help with any of these, please do reach out to your contact at the GraphQL Foundation.

• Do you have a venue?
  • How many people can it safely fit?
  • Does it have specific access requirements? Do you need to register a visitor list ahead of time? Does someone need to be at the door greeting?
  • Is it accessible to people with disabilities?
  • How can people get there using public transport?
  • Is it easy to find?
• Do you have the necessary equipment to record the talks/hear the speakers?
• Buying such things are allowed costs for the sponsorship.

Release Notes 2024-05-09

This is a huge release, folks! Our last release was 12th Feb, so this covers the 3 month period since then. I finally caught up enough to attack some of the bigger issues in Grafast (specifically the "early exit" and "global dependencies" issues discussed at the first Grafast WG); this has required some breaking changes to the API but as always I've kept these to an absolute minimum; migration steps are outlined below.

Streamed JSONL

Each payload is just appended as a condensed JSON (no newlines!) payload, with a newline at the end:

HTTP/1.1 200 OK
Content-Type: application/graphql-response+jsonl
Cache-Control: no-cache

{"data":{...},"hasNext":true}
