💬 **Talks:**

1. **Adopting GraphQL, Scaling it, Fixing Reliability and Making it Solve Unique Problems**
🎤 *Speaker: [Alex Komlev](https://www.linkedin.com/in/komlev/), Sr. Engineering Manager @ Booking.com Platform. Alex brought GraphQL to Booking.com in 2020, proved its value and helped scaling it to all parts of the business.*

Why did we choose GraphQL?
How did we make our product managers love it?
What else helps to overcome organizational resistance?
How did we hit our first limits?
Why we moved from Java to NodeJS? And why we're discussing Rust?
What happened when we couldn’t access our schema? And why this was a great lesson?
What's needed to make a GraphQL layer five nines reliable?
How to scale support to hundreds of internal clients?
What's in our multiyear data access strategy?
And... how many GraphQL engineers does it take to change a light bulb?

2. **Schema Scoring: Ensuring Schema Excellence in GraphQL**
🎤 *Speaker: [Christian Ernst](https://www.linkedin.com/in/christian-ernst11), Sr. Engineer @ Booking.com GraphQL team. Chris took care of Booking GraphQL Federation since its infancy, and multiple times saved the company together with millions of dollars. Chris is also a NodeJS expert and a [serial ](https://graphql.org/conf/2024/schedule/6e20cd3c4ee36577f15713955444338f/)[speaker](https://www.youtube.com/watch?v=2KsP_x50tGk&list=PLP1igyLx8foE9SlDLI1Vtlshcon5r1jMJ&index=54)!*

At Booking.com we have scaled to over 120+ subgraphs and that number continues to grow. As subgraphs develop it has begun to be impossible for one to team to oversee all of the changes to the graph. We created best practices and guidelines for GraphQL schemas, but soon recognised we need to track the quality of schemas automatically and in a way that can provide actionable feedback to teams. At Booking.com we have developed the infrastructure to analyse schemas beyond standard linting to help improve the quality of the Graph across the board enabling better efficiency & developer experience for everyone.

💡 **What we will discuss**:

* GraphQL Federation vs monolithic GraphQL
* Major GraphQL flows and how to prevent them
* Challenges with defining GraphQL layer SLOs
* Non-trivial GraphQL use cases (e.g. service-to-service)
* Centralized vs distributed information architecture
* Can we trust client-side engineers & random queries?
* Quality of GraphQL schema & ways to automate it

Looking forward to welcoming you and discussing our and your unique GraphQL practices! 👋

Hey folks!

Join us for an exciting Dec meetup in San Francisco! We've got Robert Balicki from Pinterest talking about making your app more performant with Isograph.

**Meetup Details**

* **Date**: Dec 3rd
* **Time**: 5:30pm to 7pm
* **Location**: [Hasura Office](https://maps.app.goo.gl/GtCPHj5kagFY6epr9), 576 Folsom St floor 3, San Francisco, CA 94105, United States

**Agenda:**

* **5:30 pm**: Meetup open and networking session
* **6:00pm**: Doing the bare minimum with Isograph
* **7:00 pm**: Networking

**Talk Details:**
**Talk 1:** Doing the bare minimum with Isograph

**Description:** In a web app, the enemy of performance isn't bad algorithms — it's bloat. From loading the least data and JavaScript to re-rendering the fewest components in response to changes in state, the most performant apps are the one that do the least. But it's hard to maintain a small bundle while iterating on features.

Enter Isograph, the framework for building data-driven React apps. It leverages a compiler to provide great DevEx and performance, right out of the box.

In this talk, find out how Isograph lets you:

* Load component JavaScript and data only when needed, for example when the user is about to scroll to them (yes, that's Relay entrypoints)
* Load components (such as a \`VideoViewer\`) only if an item of that type (a \`Video\`) is returned from the server (yes, that's Relay 3D), and
* Defer loading parts of your component tree, without server support.

And the cherry on top? We're doing it all in userland.![😎](https://fonts.gstatic.com/s/e/notoemoji/15.1/1f60e/32.png)
**Speaker:** [Robert Balicki](https://www.linkedin.com/in/robertbalicki/) is a staff engineer at Pinterest

GraphQL SF Meetup #6

Capital One

It's been some time since the last GraphQL Amsterdam Event and we'd love to organize new editions!

Currently, we're on the look for companies willing to host us in their office. The last meetup had around 100 people present, so we're looking for locations being able to accomodate that. The date is 100% flexible, the current meetup date is just a placeholder.

If your company has an office in Amsterdam that could host us, please reach out to Erik Wrede on LinkedIn ( [https://www.linkedin.com/in/erikwrede/](https://www.linkedin.com/in/erikwrede/)). Alternatively, please send your E-Mail address to Erik Wrede via Meetup DMs.

Hope to see you soon at the next Meetup!
