GraphQL Introduction

GraphQL Server Development
@nikolasburk

3 parts of a GraphQL server
1. Structure: The GraphQL schema
2. Behaviour: Resolver functions
3. Network Layer: Network, Middleware, …

1) The GraphQL Schema
• Strongly typed & written in GraphQL Schema Deﬁnition
Language (SDL)
• Deﬁnes API capabilities ( = contract for client-server
communication)
• Special root types: Query, Mutation, Subscription
@nikolasburk

Example: Hello World
SCHEMA
@nikolasburk
SERVER RESPONSEQUERY

Example: CRUD for User type
@nikolasburk

2) Resolver functions
• Concrete implementation of the API
• One resolver function per ﬁeld in SDL schema
• Query execution: Invoke resolvers for all ﬁelds in query
@nikolasburk

Example: Hello World
SCHEMA
@nikolasburk
RESOLVER

Example: CRUD for User type
@nikolasburk

3) Network Layer
• Based on `graphql-yoga`
• Network conﬁguration: port, endpoints, CORS, …
• Middleware (analytics, logging, crash reporting,…)
@nikolasburk

…putting it all together
1) SCHEMA
2) RESOLVERS
3) NETWORK LAYER

Building a clone of the Medium API
…from scratch
• Queries
• Retrieve a list of all posts (or filter for `title` or `content`)
• Retrieve a single post by its ìd`
• Mutations
• Create a new draft
• Publish a draft
• Delete any post by its ìd` (published or draft)
@nikolasburk

Architecture

Steps
@nikolasburk
Step 0: Minimal GraphQL server
Step 1: Extend API with query arguments
Step 2: Complete API operations
Step 3: Add database layer with Prisma and Prisma bindings
Step 4: Complete API operations against the database

GraphQL is an application layer query language from Facebook. With GraphQL, you can define your backend as a well-defined graph-based schema. Then client applications can query your dataset as they are needed. GraphQL’s power comes from a simple idea — instead of defining the structure of responses on the server, the flexibility is given to the client. Will GraphQL do to REST what REST did to SOAP?

GraphQL is a wonderful abstraction for describing and querying data. Apollo is an ambitious project to help you build apps with GraphQL. In this talk, we'll go over how all the parts—Client, Server, Dev Tools, Codegen, and more—create an end-to-end experience for building apps on top of any data. ## Detailed description In today's development ecosystem, there are tons of options for almost every part of your application development process: UI rendering, styling, server side rendering, build systems, type checking, databases, frontend data management, and more. However, there's one part of the stack that hasn't gotten as much love in the last decade, because it usually falls in the cracks between frontend and backend developers: Data fetching. The most common way to load data in apps today is to use a REST API on the server and manage the data manually on the client. Whether you're using Redux, MobX, or something else, you're usually doing everything yourself—deciding when to load data, how to keep it fresh, updating the store after sending updates to the server, and more. But if you're trying to develop the best user experience for your app, all of that gets in the way; you shouldn't have to become a systems engineer to create a great frontend. The Apollo project is based on the belief that data loading doesn't have to be complicated; instead, you should be able to easily get the data you want, when you want it, and it should be managed for you just like React manages updating your UI. Because data loading touches both the frontend and backend of your app, GraphQL and Apollo have to include many parts to fulfill that promise of being able to seamlessly connect your data together. First, we need client libraries not only for React and JavaScript, but also for native iOS and Android. Then, we must bring server-side support for GraphQL queries, mutations, and most recently subscriptions to every server technology and make those servers easier to write. And finally, we want not only all of the tools that people are used to with REST APIs, but many more thanks to all of the capabilities enabled by GraphQL. In this talk, we'll go over all of the parts of a GraphQL-oriented app architecture, and how different GraphQL and Apollo technologies come together to solve all of the parts of data loading and management for React developers.

GraphQL Introduction

Talk for FOSSASIA 2016 (http://2016.fossasia.org) ---- This talk will give a brief and enlightening look into how GraphQL can help you address common weaknesses that you, as a web / mobile developer, would normally face with using / building typical REST API systems. Let's stop fighting about whether we should implement the strictest interpretation of REST or how pragmatic REST-ful design is the only way to go, or debate about what REST is or what it should be. A couple of demos (In Golang! Yay!) will be shown that are guaranteed to open up your eyes and see that the dawn of liberation for product developers is finally here. Background: GraphQL is a data query language and runtime designed and used at Facebook to request and deliver data to mobile and web apps since 2012. Hafiz Ismail (@sogko) is a contributor to Go / Golang implementation of GraphQL server library (https://github.com/graphql-go/graphql) and is looking to encourage fellow developers to join in the collaborative effort.

GraphQL is a query language mostly used to streamline access to REST APIs. It is seeing tremendous growth and adoption, in organizations like Airbnb, Coursera, Docker, GitHub, Twitter, Uber, and Facebook, where it was invented. As REST APIs are proliferating, the promise of accessing them all through a single query language and hub, which is what GraphQL and GraphQL server implementations bring, is alluring. A significant recent addition to GraphQL was SDL, its schema definition language. SDL enables developers to define a schema governing interaction with the back-end that GraphQL servers can then implement and enforce. Prisma is a productized version of the data layer leveraging GraphQL to access any database. Prisma works with MySQL, Postgres, and MongoDB, and is adding to this list. Prisma sees the GraphQL community really coming together around the idea of schema-first development, and wants to use GraphQL SDL as the foundation for all interfaces between systems.

Managing data is difficult and sometimes handling JSON APIs can get confusing. Figuring out endpoints is stressful. GraphQL is here to change that. GraphQL is a query language that can be implemented in whichever programming language you want. Thanks to it, we can use a single endpoint to exchange data. Choose your data! No overfetching! In this workshop we will learn all about GraphQL by building an application from the server to the client using JavaScript.

Have you used GraphQL yet? If you haven't, you're likely to encounter the technology soon. If you have, you might have questions about how to scale your team and what best practices large and small companies are following. What principles should I be following when developing a new GraphQL API? What tooling is available to help me be more productive and spend less time writing boilerplate code? How can many teams with many apps across one company share one graph? GraphQL Conf 2019 just wrapped up in Berlin where I was fortunate to hear meet thoughtful leaders on these and other subjects related to GraphQL. So, whether you're brand new to GraphQL or have an active project using GraphQL, I'd like to share some of what I have learned so you can be productive with GraphQL and your teams - while keeping relationships at the center of our work.

Originally designed by Facebook to allow its mobile clients to define exactly what data should be send back by an API and therefore avoid unnecessary roundtrips and data usage, GraphQL is a JSON based query language for Web APIs. Since it was open sourced by Facebook in 2015, it has undergone very rapid adoption and many companies have already switch to the GraphQL way of building APIs – see http://GraphQL.org/users. However, with some many hundreds of thousands of REST APIs publicly available today (and many thousands others available internally), what are the implications of moving to GraphQL? Is it really worth the effort of replacing REST APIs specially if they’re successful and performing well in production? What are the pros/cons of using GraphQL? What tools / languages can be used for GraphQL? What about API Gateways? What about API design? With a combination of rich content and hands-on demonstrations, attend this session for a point of view on how address these and many other questions, and most importantly get a better understanding and when/where/why/if GraphQL applies for your organisation or specific use case.

GraphQL is query language for APIs, but what are the advantages and how would one implement such in their microservices/APIs. In this session, I will go through the basics of GraphQL, different aspects of GraphQL and architecture of such APIs. There will be a demo/live-coding on, how 3 different ways we can implement GraphQL for a Springboot microservice/API. Lots of examples, live coding and helpful comparison on structure, usage and implementations of GraphQL in Springboot & Java world.

GraphQL is an emerging API standard that provides a more flexible and alternative approach for data intensive operations. It is particularly good for querying and retrieving data in optimized forms that make applications more efficient and optimal. While GraphQL focuses on what it does best, we still need to ensure that our GraphQL services are exposed in a secure, controlled, monitored, and sometimes even in a monetized environment. This is where the inclusion of an API gateway that understands GraphQL queries, mutations, and subscriptions can add significant value.

Foundation models are machine learning models which are easily capable of performing variable tasks on large and huge datasets. FMs have managed to get a lot of attention due to this feature of handling large datasets. It can do text generation, video editing to protein folding and robotics. In case we believe that FMs can help the hospitals and patients in any way, we need to perform some important evaluations, tests to test these assumptions. In this review, we take a walk through Fms and their evaluation regimes assumed clinical value. To clarify on this topic, we reviewed no less than 80 clinical FMs built from the EMR data. We added all the models trained on structured and unstructured data. We are referring to this combination of structured and unstructured EMR data or clinical data.

Data spaces in distributed environments should be allowed to evolve in agile ways providing data space owners with large flexibility about which data they store. Agility and heterogeneity, however, jeopardize data exchanges because representations may build on varying ontologies and data consumers may not rely on the semantic correctness of their queries in the context of semantically heterogeneous, evolving data spaces. Graph data spaces are one example of a powerful model for representing and querying data whose semantics may change over time. To assert and enforce conditions on individual graph data spaces, shape languages (e.g SHACL) have been developed. We investigate the question of how querying and programming can be guarded by reasoning over SHACL constraints in a distributed setting and we sketch a picture of how a future landscape based on semantically heterogeneous data spaces might look like.
