How to Edge Cache GraphQL APIs
For years, not being able to cache GraphQL was considered one of its main downsides compared to RESTful APIs. Not anymore. GraphCDN makes it possible to cache almost any GraphQL API at the edge, and not only that but our cache is even smarter than any RESTful cache could ever be. Let's dive deep into the inner workings of GraphCDN to figure out how exactly we make this happen.

Evaluating GraphQL for Setting Up an Enterprise-Grade Data Mesh
I'll introduce the concept of a data mesh and why people increasingly are gravitating towards that as a solution to their data (both online and analytical) and application modernization problems. I'll talk about the key requirements around 1) domain-oriented decentralized data ownership and architecture, 2) data as a product, 3) self-serve data infrastructure as a platform, and 4) federated computational governance (ref). And then I'll talk about how GraphQL opens up an opportunity for laying the foundation for a data mesh and best-practices in building, operating and maintaining an enterprise grade data mesh.

Putting the Graph In GraphQL With The Neo4j GraphQL Library
GraphQL exposes application data as a graph which can introduce challenges if your backend isn't graph-ready (think slow JOINs as a result of nested GraphQL queries and the dreaded n+1 query problem). The Neo4j GraphQL library enables developers to build GraphQL APIs backed a native graph database using only GraphQL type definitions. In this talk we'll see how to build a GraphQL API without writing any resolvers, add custom logic, and deploy to the cloud.

GraphQL Performance and Monitoring
GraphQL abstracts the downstream API calls from the frontend and all that frontend has to do is request fields in a query that are required for the rendering of the component. The frontend is not aware that a corresponding field might result in an API call or heavy computations on the backend side. This abstraction hits the performance when the GraphQL schema is not structured properly. Let's take an example to understand more:
Here's the query to get available rooms for a hotel:
hotel (id: $hotelId) { id rooms { id type name } }
The frontend doesn't know that the
rooms
field inside the query
hotel
will fire another API call even
type
field would be fetched from another API endpoint. These nested API calls worsen the performance if there are more rooms. We can effectively solve this structuring the schema well and using data loaders.

Exploring the WordPress Graph with Next.js & WPGraphQL
Headless Wordpress using its built-in REST API is a powerful solution to scale WordPress to the web, but complex relationships can easily turn into chains of requests, making maintainability difficult along with the potential cost of performance.
With WPGraphQL, we can harness the benefits of GraphQL, leading to a better developer experience and optimized request logic, making sure we’re only delivering what we need to our users.
We’ll explore these advantages and how these pieces fit together with modern tools like Next.js to build great experiences for the web.

All Things Graph...
REST is an API design architecture, which, in the last few years, has become the norm for implementing web services. It uses HTTP to get data and perform various operations (POST, GET, PUT, and DELETE) in JSON format, allowing better and faster parsing of data. But REST comes with some downsides that have enterprises considering alternative mechanisms to manage performance, developer time, and production of their APIs — enter GraphQL. GraphQL doesn't have to be a replacement to REST, the two API designs can co-exist and be leveraged for the appropriate use-case. Join us for a conversation about what benefits, shortcomings, tooling, and design decisions you need to consider while making this evaluation.

Building GraphQL APIs on Ethereum
Blockchains are databases with a unique set of properties. Unlike most databases which are optimized for both read and write operations, blockchains are optimized for write operations, typically focused on optimizing and scaling transaction cost, transaction volume, and transaction speed.
In this talk, I'll dive into the web3 space, and show how developers can leverage The Graph Protocol to build performant, scalable, and decentralized GraphQL APIs and dapps on decentralized networks like Ethereum and IPS.

Building a Serverless GraphQL API in 7 Minutes
At the beginning of the COVID-19 pandemic, Johns Hopkins University worked on gathering and refining data from multiple sources and provided the world with a Github repository and a bunch of CSV files. The Problem? It’s nearly impossible to build anything from raw data like this.
In this live coding session, MongoDB Developer Advocate Maxime Beugnet will show you how to build a serverless GraphQL API based on this dataset using Python and the MongoDB Data Platform. We are finally going to put serverless and the MongoDB generous free tier to good use!

Scalable GraphQL Applications Powered by Cloud-ready Distributed SQL Database
Cloud native application development revolves around faster prototyping and building scalable applications for handling internet-scale traffic. GraphQL, with its roots in providing a flexible way to access data for UX applications, enables faster prototyping, leading to considerable adoption of GraphQL across different workloads. Increased adoption of GraphQL APIs in mission-critical applications prompts developers to think about the scalability challenges of the GraphQL APIs and corresponding backing database.
YugateDB, an open-source Distributed SQL database designed for cloud native applications from the ground up, is emerging as the popular option for building scalable and resilient GraphQL APIs. This talk will go over the features and deployment topologies of YugateDB, which allows developers to scale the relational queries of the GraphQL APIs seamlessly while not compromising on the PostgreSQL compatibility and features like triggers and functions.

GraphQL Caching Demystified
How would you implement a performant GraphQL cache? How can we design a good algorithm for it? Is there a good Open Source solution that is efficient, scalable and easy to deploy? How is the caching key computed? What about cache invalidations? Would it be possible to deduplicate resolver execution? This might be seen as daunting but in reality is all code and algorithms.
In this talk we are going to walk through a GraphQL caching system that we have developed for Mercurius - one of the fastest GraphQL servers for Node.js.

GraphQL + Apollo + Next.js: A Lovely Trio
Modern frontend applications want to efficiently query data on page load and navigate, format the data with TypeScript, and cache data between repeat requests. Setting that all up on your own is a chore... but with Apollo and Next.js, you can set up your client to auto-generate TypeScript types, cache query results intelligently, and generally be a breeze to work with.

Semantic Search through the Complete Wikipedia with Weaviate’s GraphQL API
Weaviate uses GraphQL to provide user-friendly data interaction. Weaviate is an open-source vector search engine, and all searches (e.g. semantic, contextual) are done via its GraphQL API. We’ve put a lot of thought into the design of the GraphQL API, which results in good user and developer experience. In this talk, I will take you along in the journey of how our GraphQL implementation was shaped according to user needs and software requirements, and show a demo of the current design for Weaviate. The demo will show how Weaviate’s GraphQL design enables semantic (vector) search in combination with scalar search through unstructured data. Machine learning models are used in the background, but with the current GraphQL design, users without a technical background can query the vector database easily.
Weaviate has a modular architecture, so users can connect various machine learning models on top of the vector database. Examples are the newly released Question Answering module and the Named Entity Recognition module. Modules can extend the GraphQL schema dynamically, to query the new features intuitively.
This presentation contains a demo where we will query the complete Wikipedia, conduct semantic search queries and more. All through Weaviate’s GraphQL API. No prior knowledge is required.
