200 Is Not OK: Strategies for Tracing Partial Responses with GraphQL Observability - Aditi Rajawat & Rama Palaniappan, Intuit
Tuesday September 10, 2024 10:50am - 11:20am PDT
Skyline B-C
GraphQL is agnostic to the transport layer. Almost all out of the box observability tooling is tailored to REST/HTTP APIs. Major observability challenge with GraphQL over HTTP is the support of partial response and HTTP status with 2XX may have failed. GraphQL Gateway generally fans-out one incoming request to one or many outgoing subgraph requests. It is essential to monitor each subgraph and the GraphQL gateway’s metrics and also to trace a single request across the network stack. This talk will cover how Intuit is reducing Mean Time to Detect (MTTD) and Mean Time to Recover (MTTR) for GraphQL APIs, by capturing Failed Customer Interactions, Golden Signal to determine gateway and subgraph’s health, latency, error rate and other related metrics. This talk will also cover open tracing and logging for GraphQL APIs.

Schema-Driven Testing with Mock Service Worker - Alessia Bellisario, Apollo
Tuesday September 10, 2024 10:50am - 11:20am PDT
Skyline A
At last year’s GraphQL Conf, Stephanie Saunders sang the praises of schema mocking in her excellent talk “Sophisticated Schema Mocking”. As Stephanie outlined, tests written using mock schemas have several benefits over ones written with static response mocks (seriously, go back and watch the talk if you haven’t!) Mock schemas are the perfect pair for Mock Service Worker which describes itself as “an API mocking library that allows you to write client-agnostic mocks and reuse them across any frameworks, tools, and environments.” In this talk, I’ll demonstrate how to use mock schemas with MSW using testing tools created by the Apollo Client team. These utilities can be used with any GraphQL client for the web whether it’s Apollo Client, Relay, urql, isograph or even just plain fetch requests to a GraphQL endpoint, and support incremental delivery (@defer/@stream), subscriptions and more. With MSW + your front-end stack of choice + test runner or framework of choice (Jest, Puppeteer, Cypress, Storybook, the list goes on) this talk will teach you how to level up the tests you and your team are writing.

GraphQL in the House - Andrew Doyle, U.S. House of Representatives
Tuesday September 10, 2024 10:50am - 11:20am PDT
Metropolitan A
An overview of how the Office of the Clerk has used GraphQL to modernize a large legacy system used to manage legislative data and processes in the House of Representatives. The talk will cover architecture, technologies, process and an overview of our application. We have moved significant portions of our application from a legacy database management and application framework to a modern relational database with a microservice business logic layer and a single page application client. GraphQL is used to tie the application, data and business logic together in a single API that is shared across multiple applications and modules. The initial approach has evolved into a platform for building applications that host complex data and business logic. We are also evolving our architecture to deliver data from our applications directly to legislative branch partners over a GraphQL endpoint, replacing multiple legacy delivery methods.

GraphQL at the Edge with WebAssembly - Ramnivas Laddad, Exograph, Inc
Tuesday September 10, 2024 11:30am - 12:00pm PDT
Skyline B-C
WebAssembly is reshaping our approach to software execution units and components. With its ecosystem maturing--the ability to deploy with multiple cloud providers, the standardization of WebAssembly Components, and the rise of WASI--its potential is fast becoming a reality. WebAssembly is especially suitable for running server-side code at the edge, where resource constraints and security concerns are paramount. To realize the full potential of running API servers at the edge--lowered latency, reduced costs, and improved scalability--we must rethink our approach to building and deploying servers. GraphQL is particularly well-suited for edge deployments. It not only reduces the number of trips between the client and the server but also allows implementations to optimize the whole query to reduce round trips to the data server. In this session, we will explore how to target a Rust implementation of GraphQL server to WebAssembly. We'll also look into how this fits within the WebAssembly ecosystem and how you can run these servers even in your browser.

The Power of Strongly Coupled GraphQL Queries for Internal APIs - Mary Briskin, Tutored by Teacher
Tuesday September 10, 2024 11:30am - 12:00pm PDT
Skyline A
The purpose of this talk is to communicate the value of writing focused code, avoiding over-generalization. This presentation argues that fetching data in the exact shape we want it is more valuable than reusability when it comes to internal APIs. The audience will learn about the benefits of tightly coupling your pages and GraphQL queries: - Avoid front-end data manipulation - rigid schema types that are too closely tied to your data models require messy data aggregation in the front-end - Easier to change - changing a type doesn't have cascading consequences when it is only used by a single query - More explicit about being single-use - the alternative is often to add generic-sounding fields to your graphQL schema even when they will only ever be used in a single place ~~~ Learn the benefits of tailoring your private GraphQL APIs to be highly specific. This focused approach not only simplifies front-end development but also boosts back-end performance, allowing for rapid adaptations and enhanced efficiency. Discover how crafting precise queries can lead to cleaner and faster code.

Incrementally Adopting GraphQL and Relay at Pinterest - Mauricio Montalvo, Pinterest
Tuesday September 10, 2024 11:30am - 12:00pm PDT
Metropolitan A
Pinterest is too large to simply “rewrite our app” to use GraphQL in one fell swoop. Even migrating an individual screen takes months, at our scale this is quite challenging, like changing a plane’s engine while flying. Is GraphQL adoption destined to be difficult for large companies? Can this process be made more incremental? Unfortunately, the answer seems to be no. It's hard to imagine how components consuming GraphQL data can coexist on a page that makes network requests to a REST endpoint. And yet, we figured it out. And we had a good time, too! We designed Relay-compatible APIs that allow us to read data either from a GraphQL store or from arbitrary objects (e.g. from Redux.) So, engineers can migrate individual components within a larger tree. These components specify the data they need using a fragment, and receive GraphQL-shaped data, regardless of whether the data came from GraphQL or REST. When a component tree is fully migrated, we're able to A/B test the REST and GraphQL endpoints, and only turn on GraphQL when we're sure doing so won't degrade any metrics. And we're about to release this to open source: adopting GraphQL on the front-end has never been easier!

Building a Serverless GraphQL Subscription Gateway for Event-Driven Architectures - Christian Stangier & Kenneth Wußmann, MOIA GmbH
Tuesday September 10, 2024 1:30pm - 2:00pm PDT
Metropolitan A
At MOIA we're working on a new approach to mobility using ride-pooling with autonomous vehicles. Running an autonomous fleet of vehicles requires access to real-time and low-latency telematic data. This data needs to be made accessible to our users on a fleet map to always have a detailed overview of the current fleet state. Using only queries and polling we quickly ran into scalability issues and had to rethink our approach. Therefore we went to the drawing board and designed and built a serverless architecture on top of AWS and GraphQL over WebSocket to support our stream-aligned teams in building serverless subscriptions in a microservice environment. Watch a replay of our journey enabling other teams to effortlessly push updates to their users using a shared subscription gateway.

In Memory of Travails - Gabriel Schulhof, Auction.com
Tuesday September 10, 2024 2:10pm - 2:40pm PDT
Skyline B-C
Two aspects of resolvers have an outsized influence on their performance: the size of the execution context, and the way we compute their value. In the Node.js implementation of graphql, promises wrapping primitive values are especially disruptive, since they add a large computing overhead. The context size creates a memory usage baseline that can rise very quickly with even small additions to the context, when there are many concurrent contexts. The execution can create temporary objects, increasing memory usage. Often-run resolvers, such as those responsible for filling out large arrays of objects, can become performance bottlenecks. At Auction.com, our search results page (SRP) requests up to 500 items of roughly 80 fields each. The query resolving these fields was suffering a high latency. We shall examine the tools to instrument our code and identify memory usage and CPU utilization bottlenecks. Our realtime elements (e.g. realtime updates to the status of currently viewed properties) are implemented using a translation of kafka messages to graphql updates. We shall present the tools and procedures to reduce memory usage and CPU usage when fanning out such messages.

Championing the GraphQL Client in a Modern Platform - Jeff Auriemma, Apollo GraphQL
Tuesday September 10, 2024 2:10pm - 2:40pm PDT
Skyline A
GraphQL is becoming the preferred choice for enterprise API development. That means that more and more app developers are adopting GraphQL client libraries as part of a larger platform strategy rather than building their own BFFs. Platform owners, engineering leaders, toolmakers, and application developers can leverage this adoption pattern to set their teams up with an easy on-ramp and a roadmap for long-term success. My talk will outline the design features common across GraphQL client libraries and why they are essential for platform engineers to understand. I’ll share insights my team has gathered from our open-source projects, user interviews, and surveys that reveal how GraphQL newcomers and veterans relate to these tools. All of this will be tied together with some practical advice for every stage of the adoption journey: crawl, walk, run.

Improve Application Performance and User Engagement with Advanced GraphQL Features - Kewei Qu, Meta
Tuesday September 10, 2024 2:50pm - 3:00pm PDT
Skyline A
In this talk, I will go through two recent experiments at Meta where we improved Application scroll perf (commonly known as frame drops) and media stalls by developing advanced GraphQL features. 1. Batched @defers. Common UI update cycles with regular defers will introduce increased state updates and may cause unnecessary re-renders. By batching deferred payloads carefully, we can achieved improved latency without introduce frame drops which is commonly associated with decreased engagement. 2. Improved CDN prefetch. Most of the time, the bottleneck to TTI is the media loads, either image load or video load. Commonly, Applications prefetch these media from CDN to improve stalls. We can make the prefetch better by using the visitor pattern which is available in many GraphQL library to enable prefetch during parsing time.

GraphQL Is for Client Developers, Not Client Applications - Michael Bleigh, Google
Tuesday September 10, 2024 3:40pm - 4:10pm PDT
Metropolitan B-C
Many of the most common issues developers run into when building GraphQL APIs (N+1 queries, difficult authorization logic, protecting against arbitrary query complexity) come down to a single problem: when an untrusted client can construct arbitrary queries, lots can go wrong. So what if they just couldn't? The wins of GraphQL aren't in letting *clients* build their own queries but in letting *client developers* build their own queries. When Firebase chose GraphQL as the basis for its new Data Connect product, we introduced "Connectors", a new resource type that bundles a group of predefined GraphQL queries and mutations and exposes them at an endpoint. While trusted servers can execute arbitrary queries, untrusted clients can only use predefined queries and mutations. This approach substantially simplifies the security model of building with GraphQL. Rather than worrying about every possible query, you can build authorization and complexity mechanics around well-known predefined queries. Learn the how, the why, and the possible future of "Connectors" for GraphQL in Firebase and beyond.

Generating GraphQL Fragments from Static Analysis of Code - Vinicius Brown, Pinterest
Tuesday September 10, 2024 4:20pm - 4:50pm PDT
Metropolitan B-C
One of the most boring, laborious, and error-prone processes in GraphQL adoption is manually writing a fragment with all the fields that a given component will use. It requires engineers to track the fetched data through child components, conditionals, and function calls. We humans aren't good at being consistent and thorough — but computers are! That's why we decided to write a tool to generate appropriate fragments based on field usages! With this tool, developers add a JavaScript comment telling the program to track a given variable, run the algorithm, and voilà! They receive a fragment that selects just the fields used by that function. It even works across files, functions and classes — you can run the tool once for an entire component tree. The resulting fragments will contain fragment spreads that track the data from function to function, drastically reducing the time it takes to implement GraphQL in the frontend. In this presentation, I will show the tool, explain the use case and the road map, and then demonstrate this tool by generating fragments for an entire component tree. GraphQL adoption has never been easier!

Metropolitan A
Getting a good understanding of how your GraphQL server performs and tracking down issues that you might not yet see is difficult with GraphQL. This is because the requests to your GraphQL server are defined by your consumers. With the emergence of OpenTelemetry, we now have tooling to build a great GraphQL cockpit that turns the lights on in GraphQL and shows you exactly which GraphQL requests use what in your infrastructure. The best thing is that OpenTelemetry is an open standard, allowing you to pick and choose tooling and vendors. Let’s explore how we can integrate OpenTelemetry into GraphQL from backend to frontend.

Learn about the scaling challenges we faced in terms of infrastructure, organizational growth, and the technological aspects of GraphQL usage within a hyper-growth startup. In September 2016, when our team of ten-odd full-stack engineers adopted GraphQL, we were handling a few thousand requests per second on our GraphQL layer. Fast forward to 2023, the engineering team has grown to 1,000 members managing half a billion requests per minute at peak. In this talk we aim to address critical questions regarding GraphQL's performance, when is the right time to integrate it, exploring whether GraphQL is predominantly a front-end abstraction or if it can also be effectively utilized in back-end operations for service-to-service communication. Drawing from years of extensive GraphQL usage at a significant scale—without the need for federation—we will introduce for the first time an open-source project that helped us elegantly design, streamline, and scale optimal GraphQL APIs.

Why You Should Use Implementation-First to Build Your GraphQL Schema - Erik Wrede, fulfillmenttools
Wednesday September 11, 2024 10:50am - 11:20am PDT
Skyline B-C
When we look at GraphQL server implementation approaches, you often see the discussion between code-first and schema-first as a schema building approach. What is overlooked is that Facebook actually built their Hack-based GraphQL server with implementation-first. This approach will infer the GraphQL schema from your code, and by extension from your business layer. In this talk, I will look at various implementations of implementation-first and explain why Facebook chose this approach to build their own GraphQL server and why it is actually the better approach in most projects.

GraphQL Field Discovery and Query Generation Using Generative AI - Rachit Sengupta & Siva Thiru, Intuit
Wednesday September 11, 2024 10:50am - 11:20am PDT
Metropolitan B-C
Discovering GraphQL fields and generating queries is a tedious task for developers. They spend a considerable amount of time finding the appropriate fields in large schemas. To solve this problem at Intuit where we have a super graph consisting of millions of lines we implemented a framework that makes use of Generative AI to help developers with attribute discovery and query generation. The benefits of our approach include being able to work with large schemas without the hassle of going through the whole schema and requiring less back and forth communication between consumers and schema owners, which results in a huge boost in developer productivity. We created chunks of the schema and ingested them into a vector store, we then do a retrieval, dynamically build a minimal schema and perform RAG where the LLM is provided with the minimal schema and the user query. The LLM responds with either a list of discovered attributes or GraphQL query. This framework aims to achieve lower latency and less hallucinations by reducing the size of the schema sent to the LLM, this also results in lower costs and higher accuracy.

Using Client-Side GraphQL Data to Reduce Server Costs - Sabrina Wasserman, Meta
Wednesday September 11, 2024 10:50am - 11:20am PDT
Metropolitan A
In this talk, I’ll discuss how we utilize an in-memory client-side GraphQL data store at Meta to reduce unnecessary network fetches, and reduce server latency for executed requests by dynamically skipping fields that can be fulfilled by our in-memory store. Specifically, I'll cover: - What are Abstract Syntax Trees (ASTs), and how do they allow us to determine if a query's data is fulfillable from an in-memory data store. - GraphQL Partial Rendering - How we at Meta are able to immediately vend partial query responses from an in-memory store for more response UIs. - How we dynamically skip client-side fulfillable fields, and only fetch missing fields from the server to reduce server costs

Skyline B-C
Existing GraphQL frameworks are well designed to handle statically defined types and resolvers. Here at Benchling, we faced the problem of serving a GraphQL API which incorporated customer-defined types at runtime with a dynamically generated graph that varies customer-to-customer. In this talk, I’ll describe some of the challenges in serving this GraphQL API, including dynamic generation of graph components and performance. Then, I’ll describe how we extended Strawberry (the GraphQL framework we decided to use) to handle our use cases as well as a graph-caching strategy that allowed us to dramatically improve the performance of serving the API.

GraphQL Docs: Beyond the Schema - Sarah Sanders, Highnote
Wednesday September 11, 2024 11:30am - 12:00pm PDT
Metropolitan B-C
GraphQL Docs: Beyond the Schema is a presentation focusing on how Technical Writers and DevEx teams can enhance developer experience with interactive documentation. I hope to inspire DevEx teams and Technical Writers to consider GraphQL as more than just "self-documenting." The problem I will present is that I want more than a schema as a developer. I want to know how to use the schema to build my product. The solution to the problem will focus on interactive documentation by defining what makes it interactive, for example, embedded code samples linked to a user's sandbox environment. I will then explore how DevEx teams can implement these elements to create interactive documentation for their GraphQL API. I expect the audience to gain insight into exactly how they can create their own interactive GraphQL documentation and best practices. This presentation will help better the ecosystem by highlighting the pain points of GraphQL documentation as it exists today, emphasizing the need to create interactive documentation for developers working with GraphQL, and enforcing the importance of creating rich developer experiences.

Advancing the Web for Local-First and Reactive Architectures with GraphQL Live Queries - Omri Bruchim, Edginary
Wednesday September 11, 2024 11:30am - 12:00pm PDT
Skyline A
The web feels ready for a major upgrade. "Local-first" is emerging as a paradigm that shifts reads and writes to an embedded database in each client, facilitated by “sync engines” that handle data exchange between clients and servers. Applications like Figma and Linear have pioneered this approach, and it's becoming increasingly accessible. The benefits are manifold (built-in support for real-time sync, offline usage, collaborative apps, Faster UX) While GraphQL Subscriptions have been part of the GraphQL Specification for some time, GraphQL Live Queries remain an RFC and are not yet standardized. In this talk, we will: - Recap GraphQL Live Queries and it's role in real-time applications - Explore current Live Query solutions - Discuss the challenges and benefits of real-time and reactive applications - Challenges in such implementation like (Maintaining a local state synchronized with the server, managing partial materialized views, Utilizing CRDTs for parallel mutation handling and more) The talk will conclude with a demo of an application utilizing Custom GraphQL Live Queries, showcasing its architecture and capabilities.

Dynamic (but Safe) Operations: Using AI to Generate Trusted Operations from Text Prompts - Michael Watson, Apollo GraphQL
Wednesday September 11, 2024 1:30pm - 2:00pm PDT
Skyline B-C
Platform engineering and internal developer portals have been a growing trend in the tech industry to make developers more efficient. For example, how do we help new developers ship their first feature faster? GraphQL helps Platform API efforts ship features faster, but what about when your schema gets very complex? How can a new developer find what they need quickly? GraphQL already provides a complete and understandable description of the data in our APIs, but what if we provide that context to a LLM? In this talk, we'll journey through GitHub's APIs and explore how a GraphQL schema is a significant advantage in AI-based tooling. We're seeing more AI-based tools generate fetch code based on OpenAPI definitions, and while they may be tempting at first, it could be a decision with unexpected trade-offs. We'll show how to take a standard open-sourced LLM and provide a GraphQL-aware context to generate operations from text input. After this talk, you can safely bring AI to your developer efficiency initiatives with any LLM, 3rd party, or self-hosted!

Schema-Driven UI Components: Revolutionizing Headless ERP with GraphQL - Seiya Izumi & Masanori Uehara, Tailor Inc.
Wednesday September 11, 2024 1:30pm - 2:00pm PDT
Metropolitan B-C
Modern ERPs must be highly customizable and easily integrated with other systems while generating UI components on top should be seamless. In this talk, we will explore why GraphQL, with its robust and flexible querying capabilities, is exceptionally suited for developing modern ERP solutions. In addition, we’ll explore the technical aspects of generating front-end UI components directly from the GraphQL schema, what we call Schema-Driven UI, not Server-Driven UI. This approach is particularly beneficial in the ERP domain, where dynamic and complex data interactions are common. Automating the process of generating UI components directly from the Schema ensures consistency across systems by keeping everything in sync.

Semantic Nullability: A Path Toward Safe Non-Null Fields - Jordan Eldredge, Meta
Wednesday September 11, 2024 1:30pm - 2:00pm PDT
Skyline A
One of GraphQL’s killer features is field-granular error handling which can dramatically increase the resiliency of network responses. However, this has traditionally come at the cost of developer ergonomics, with client developers being forced to contend with nearly every field potentially being null. In the last year, members of the Nullability Working Group, and engineers at Meta have been exploring how we can untangle nullability and error handling in order to safely allow clients to “see” the true nullability of the server’s resolvers without sacrificing response residency. In this talk we’ll explain the ideas and RFCs that underpin this change, share the work we’ve done at Meta and across the community to validate this approach, and demonstrate Semantic Nullability in action!

Schema Scoring: Ensuring Schema Excellence in GraphQL - Christian Ernst, Booking.com
Wednesday September 11, 2024 2:10pm - 2:40pm PDT
Metropolitan B-C
At Booking.com we have scaled to over 120+ subgraphs and that number continues to grow rabidly as we modernize our frontend and backend. As subgraphs develop it has begun to be impossible for one to team to oversee all of the changes to the graph because of the rapid changes that occur from teams. As we have grown we created best practices and guidelines fro GraphQL. We soon recognised this was not enough and there was the need to track the quality of schemas over time 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 developer experience for everyone.

UNSET Fields: Differentiating Between Null and Purposeful Omissions in Your Server Response - Janette Cheng, Meta
Wednesday September 11, 2024 3:40pm - 3:50pm PDT
Metropolitan A
You've heard about distinguishing semantic vs error nulls, but what about "unset" fields? Unset fields are neither semantic or error nulls because the server has not calculated them. Why would something like this ever come up? - WhatsApp delta updates: When the client wants to tell the server, "This is the value I have for this field, only bother calculating it again and sending it down if it's out of date." - Instagram server migration from a non-GraphQL server: We started with a server that has multiple code paths to resolve a field, and now we are not guaranteed every field we request will always be resolved. Not being able to distinguish between null and unset is a problem we expect is more widespread, and to which we have found a not amazing solution that could be better if we update the spec. How do you distinguish "unset" from null? - How you achieve this today (not particularly elegant, but possible) - Omission from server response? (not currently spec-compliant)

Doing the Bare Minimum with Isograph - Robert Balicki, Pinterest
Wednesday September 11, 2024 3:40pm - 4:10pm PDT
Skyline B-C
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 often hard to maintain a small bundle while iterating on features. Enter Isograph, the framework for building React apps powered by GraphQL data. 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 (i.e. Relay entrypoints) * load components (such as a VideoViewer) only if an item of that type (a Video) is returned from the server (i.e. Relay 3D), and * defer fragments, even if your server doesn't support defer. And the cherry on top? We're doing it all in userland. 😎 But wait, there's more! We'll also show how Isograph re-renders the absolute minimum of components and garbage collects data that's no longer needed, allowing your app to stay consistently performant. So let's prove the old adage: less is more performant.

You're Our Universe: GraphQL Community Update 2024 - Benjie Gillam, Graphile
Wednesday September 11, 2024 3:55pm - 4:05pm PDT
Metropolitan A
The GraphQL ecosystem is vast, composed of tools and libraries in many programming languages, people and organizations from across the globe, and a plethora of maintainers, contributors and developers pulling them together. The primary mission of the GraphQL Foundation is to ensure that the GraphQL community is able to focus on the continued evolution of the specification, the shared contract that competitors and collaborators alike implement to enable maximal interoperability. This talk is to thank YOU, the GraphQL community, and highlight some of the heroes that have arisen to heed this call. Find out about their efforts over the last year improving our shared specifications, implementations, documentation, tooling, tests, and websites; about how you can get involved and help shape GraphQL to fit your organization's needs; about the support we have available; and about other community initiatives you may wish to avail yourself of.

Design Principles of Federated GraphQL - Martijn Walraven, Apollo
Wednesday September 11, 2024 4:20pm - 4:50pm PDT
Metropolitan B-C
GraphQL was conceived as a unified access layer that empowers product teams by providing a common language for exposing and consuming data capabilities. These capabilities were typically implemented in a single schema through a resolver-based model. That poses challenges in environments with diverse microservices managed by various teams however, as found in most large organizations. Recognizing these challenges, we introduced Apollo Federation in 2019 to deliver on the promise of GraphQL within those environments. It respects existing service and team boundaries through a principled schema composition model that supports team collaboration and efficient, query plan-based execution across services. This has allowed GraphQL APIs to effectively scale to large numbers of services and teams. Given the success and common challenges observed, a working group comprising engineers from various organizations has been formed to establish a proposed open standard for federated GraphQL. This initiative aims to unify best practices and design principles. This talk will highlight the key discussions from this group and their implications for the evolving standard.

Consuming GraphQL in Type-Safe Languages - Anthony Miller, Apollo GraphQL
Wednesday September 11, 2024 4:20pm - 4:50pm PDT
Skyline B-C
GraphQL itself is a type-safe language. A schema is composed of well-defined types, supports nullability, and allows for inheritance through interfaces. The flexibility and expressiveness provided by a GraphQL schema seems to be a perfect fit for use with type-safe coding languages. But there are many challenges to overcome when consuming a GraphQL schema in strictly type-safe languages. This talk will discuss why GraphQL seems to conflict with type safety; explore some of the notable challenges GraphQL client developers face when consuming a GraphQL API; and uncover how the Apollo team has approached solutions for many of these issues in Swift and the Apollo iOS client.

Not Your Regular Rate Limiting #GraphQL - Meenakshi Dhanani, Postman
Wednesday September 11, 2024 5:00pm - 5:10pm PDT
Skyline A
REST APIs are typically endpoint-based, meaning each endpoint has its rate limit, while GraphQL APIs tend to be more flexible and allow for a single endpoint to handle multiple requests. Although more flexible, rate limiting in GraphQL APIs is more complex than rate limiting in REST APIs. This talk discusses popular rate-limiting strategies and helps you choose the strategy that best fits your application's use case and requirements.

Build Confidently: How @Catch and Error Handling Pave the Way to Confidence in Field Nullability - Itamar Kestenbaum, Meta
Wednesday September 11, 2024 5:00pm - 5:30pm PDT
Skyline B-C
In this session - we’ll explore how GraphQL Clients can provide a road for developers to make full use of Semantic Nullability! GraphQL Spec defines that field errors should result in a null value. This makes null values ambiguous - either null due to error - or null due to nullability. Semantic Nullability allows you to define nullability explicitly - see https://github.com/graphql/graphql-wg/discussions/1410 Therefore, GraphQL Clients need to be able to handle errors differently - giving engineers more confidence in how field states are handled. In this session, we'll cover: 1. Why explicitly handling errors can enable us to move to a new normal where all errors are surfaced explicitly (throw-by-default on error) 2. How using @catch directive allows us to differentiate error nulls from true nulls in product code 3. Steps 1 and 2 will require developers to handle errors explicitly - and this opens the door to Semantic Nullability! I’ll also cover how working on the @catch directive helped push the semantic nullability conversation forward, the rollout at Meta, and what future capabilities can be unlocked. Original proposal: https://github.com/facebook/relay/issues/4416

Evolving GraphQL Schemas - Andrei Bocan, Atlassian
Wednesday September 11, 2024 5:00pm - 5:30pm PDT
Metropolitan A
The complicated bit when running a GraphQL service isn't putting together the initial schema, it's making sure to leave room for your schema to evolve, and ensuring that you're not painting yourself into a corner. In this session, we'll go through some lessons learned while developing Compass, a product we built from the ground up using GraphQL. We'll lay out some of the guidelines we've established to keep our APIs consistent, some hard and fast rules for backwards compatibility, as well as the processes we put in place to make it easy to keep things aligned. We'll also dive into how we've that all fits in with out GraphQL Gateway, which exposes a federated schema across the plethora of services that Atlassian runs, and the functionality we've isolated to the gateway.

Workshop: Scaling and Securing API Development with a GraphQL Platform - Laurin Quast & Kamil Kisiela, The Guild
Thursday September 12, 2024 9:00am - 10:30am PDT
Metropolitan B-C
Building a GraphQL API as a solo developer handling both the front end and back end in a single Git repository can be straightforward. However, in a real-world scenario, you will need to collaborate with other developers, both within your team and externally. There will be API consumers under your control, as well as those you might not even be aware of. If you use composite schemas (such as Federation), many teams will create their subgraphs to compose a supergraph. How can you safely evolve your schema without breaking clients? How do you prevent attackers from sending vulnerable GraphQL operations to your server? A schema registry can assist you and your team in successfully adopting GraphQL at scale. Discover how to gain analytics on your GraphQL API usage, avoid shipping breaking changes through CI/CD integrations, and prevent unwanted GraphQL operations by leveraging Persisted Documents using the open-source MIT-licensed Hive API platform specially designed for GraphQL.

Workshop: GraphQL Security Workshop - Tristan Kalos & Antoine Carossio, Escape
Thursday September 12, 2024 9:00am - 10:30am PDT
Skyline B-C
GraphQL’s capability to fetch precisely what’s needed and nothing more, its efficient handling of real-time data, and its ease of integration with modern architectures make it a compelling choice for modern web and mobile applications. As developers seek more efficiency and better performance from their applications, GraphQL is increasingly becoming the go-to technology for API development. However, building and maintaining GraphQL applications requires careful consideration of security. In this interactive workshop, developers and security engineers will strengthen their GraphQL security skills by learning key techniques such as complexity management, batching, aliasing, sanitization, and depth limit enforcement. They will also learn to implement customizable middleware, like GraphQL Armor, for various GraphQL server engines. Through hands-on exercises, participants will explore these techniques and packages, and apply them to enhance the safety of their GraphQL applications. By the end of the workshop, attendees will be equipped with practical knowledge to build secure and efficient GraphQL APIs.
