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 as an alternative approach to REST (as presented at Java2Days/CodeMon...luisw19
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 a specification created by Facebook that defines a query language for fetching data from backend services. It allows clients to request specific data fields from a server in a hierarchical manner and receive only the requested data. GraphQL queries are strongly typed and introspective, allowing clients to understand the structure of the returned data. While still in draft form, GraphQL is used in production by Facebook's mobile apps and provides advantages over traditional REST APIs by being more product-centric and client-driven.
- GraphQL is a query language and runtime for APIs that provides better performance, flexibility, and developer experience compared to REST. It allows clients to define exactly the structure and relations between data needed from the server.
- A GraphQL server is defined by a schema that specifies the types of objects and the fields they contain. Resolvers retrieve data and are independent of data sources. This allows GraphQL to work with various databases and services.
- Client-side frameworks like Relay and Apollo utilize GraphQL's capabilities by batching queries to minimize requests. The ecosystem is growing rapidly with server and client implementations in many languages.
This document is a presentation on GraphQL fundamentals. It was created by Virbhadra S. Ankalkote from BORN Group. The presentation covers what GraphQL is, who created it, why it was created, and how it works. It defines GraphQL as a query language for APIs that fulfills queries with existing data. It notes that Facebook developed GraphQL in 2012 for their native mobile app. In comparison to REST APIs, GraphQL allows clients to get precisely the data they need in one request. The presentation explains the GraphQL specification and includes sections on reading and writing data, using variables and fragments, and limitations such as indefinite querying depth.
What is GraphQL? Why GraphQL? How to GraphQL?
Workshops introduction presentation
GraphQL Developers https://selleo.com/graphql-expert-developers-team
1. The document discusses GraphQL, an API query language created by Facebook. It introduces GraphQL concepts like queries, mutations, and subscriptions.
2. An example compares fetching data from a REST API versus a GraphQL API. GraphQL allows fetching all required data with a single request, whereas REST requires multiple requests.
3. React and GraphQL are a good fit because GraphQL is declarative, allowing developers to focus on what data is needed rather than how to fetch it. Popular GraphQL clients like Apollo make fetching data even more declarative.
This document discusses GraphQL and its benefits over traditional REST APIs. It provides an example GraphQL query to fetch user data from Facebook's API, including the user's first and last name, number of events, friend suggestions, and number of mutual friends. It then lists some key features of GraphQL like real-time documentation, static type checking, and ability to avoid over- and under-fetching of data.
GraphQL is a syntax that describes how to ask for data, and is generally used to load data from a server to a client. GraphQL has three main characteristics:
It lets the client specify exactly what data it needs.
It makes it easier to aggregate data from multiple sources.
It uses a type system to describe data.
Getting Started with Spring for GraphQLVMware Tanzu
WaffleCorp is a major provider of breakfast products available direct to consumer or through our strategic partnerships. The current implementation of the e-commerce platform is a monolithic Spring MVC application that serves data through a collection of REST APIs.
Currently, the only provider of the REST API is our e-commerce web application. We've been tasked with opening up our APIs to our new iOS and Android apps, partner microservices, and IoT applications.
The issue we ran into is that a REST API is not a one-size-fits-all approach. We need a more flexible solution to meet the requirements of all of our client applications. This is a perfect use case for the speed and flexibility of GraphQL.
GraphQL is a query language for APIs and a runtime for fulfilling those queries with your existing data. GraphQL provides a complete and understandable description of the data in your API, gives clients the power to ask for exactly what they need and nothing more, makes it easier to evolve APIs over time, and enables powerful developer tools.
In this session, you’ll learn what GraphQL is and why you should consider it in your next project. You’ll learn how to use GraphQL in your Spring Boot applications by leveraging the Spring for GraphQL project. By the end of this session, you’ll understand how to stand up a GraphQL endpoint and request the data you need, and nothing more.
The document discusses GraphQL, a query language for APIs. It notes that GraphQL APIs are self-documenting as users can explore them using GraphiQL. It also explains that GraphQL requests are sent with a JSON body containing a "query" field with the GraphQL query string. The document is promoting a website that discusses building GraphQL APIs with .NET.
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.
This document discusses how GraphQL and graph databases are well-suited for each other. GraphQL allows clients to request specific data in a hierarchical format, while graph databases are optimized for traversing relationships. Translating a GraphQL query to a single graph database query could prevent the "N+1 queries problem" and improve performance. The document demonstrates a proof of concept for translating GraphQL queries to queries in Neo4j and OrientDB graph databases.

Tutorial: Building a GraphQL API in PHPAndrew Rota
This document discusses building a GraphQL API in PHP. It provides an overview of GraphQL concepts like queries, fields, types and schemas. It then outlines the steps to build a GraphQL API in PHP using the graphql-php library:
1. Define object types and the Query root type in the schema
2. Initialize the GraphQL schema instance
3. Execute GraphQL queries against the schema and return the result
By following these steps, one can build an API for querying a database of PHP conferences and speakers to understand how to build GraphQL APIs in PHP.
This document discusses transitioning a web application from a REST API to a GraphQL API. It covers why the company adopted GraphQL to address over-fetching and under-fetching issues, choosing the Apollo GraphQL client library, and a staged approach to transitioning including creating a GraphQL server, isolated GraphQL components, and updating legacy stores with component queries. It also provides tips on handling caching keys, response headers, mobile REST clients, server rendering, and taking a staged approach to the transition.

- Deepak Shevani works at Microsoft for the Azure group and recently became interested in GraphQL.
- GraphQL was created by Facebook in 2015 to improve client-server communication when rebuilding their native mobile apps. It defines a query language and provides a server-side runtime to fetch the desired data.
- GraphQL allows clients to get precisely the data they need through queries, reducing over- and under-fetching of data compared to REST APIs.
GraphQL is a query language for APIs that allows flexible querying of data from a server. It was originally created by Facebook in 2012 and open sourced in 2015. Some key benefits of GraphQL include allowing apps to control the specific data received from servers instead of receiving all possible data like with REST APIs, and GraphQL queries mirroring the response structure. GraphQL schemas define query and mutation parameters as well as return data types.
Build GraphQL APIs with Graphene (Big Mountain Data & Dev 2019)Ayla Khan

GraphQL - A query language to empower your API consumers (NDC Sydney 2017)Rob Crowley
The shift to microservices, cloud native and rich web apps have made it challenging to deliver compelling API experiences. REST, as specified in Roy Fielding’s seminal dissertation, has become the architectural pattern of choice for APIs and when applied correctly allows for clients and servers to evolve in a loosely coupled manner. There are areas however where REST can deliver less than ideal client experiences. Often many HTTP requests are required to render a single view.
While this may be a minor concern for a web app running on a WAN with low latency and high bandwidth, it can yield poor client experiences for mobile clients in particular. GraphQL is Facebook’s response to this challenge and it is quickly proving itself as an exciting alternative to RESTful APIs for a wide range of contexts. GraphQL is a query language that provides a clean and simple syntax for consumers to interrogate your APIs. These queries are strongly types, hierarchical and enable clients to retrieve only the data they need.
In this session, we will take a hands-on look at GraphQL and see how it can be used to build APIs that are a joy to use.
Graphene is currently the most popular framework for building a GraphQL in Python and it’s also an obvious choice for adding a GraphQL layer to Django applications. Over the course of a year, we successfully built an API with about 50 queries and over 100 mutations on top of existing Django project (Saleor), but we also learned some hard lessons and had to overcome several shortcomings of the framework along the way.
In this talk, I’d like to share some practical tips to overcome the most common problems that a Django developer might face when building an optimized and maintainable API with Graphene, such as: - using useful abstractions to build queries and mutations faster - optimizing database queries in a graph - structuring a large Graphene project - unified error handling
I’d also like to bring up a few limitations of the framework that we discovered as we were working on the project and then end the talk with the most important benefits that adoption of GraphQL brings to modern web applications development - both for the backend and frontend.
A small attempt to deliver a session on GraphQL Introduction.
I have prepared small Demo by using below technologies: Spring Boot, h2 Database (Server)
Angular 8, Apollo GraphQL Client
GraphQL is a query language for APIs that allows clients to request specific data fields from resources in a single request. It provides database independence, acts as an API middleware, and allows APIs to evolve without versioning by defining types and fields. This document demonstrates how to build a basic GraphQL API using Node.js, Express, and GraphQL tools like GraphiQL by defining a schema, root query, and relationships between types.
How easy (or hard) it is to monitor your graph ql service performanceRed Hat
- GraphQL performance monitoring can be challenging as queries can vary significantly even when requesting the same data. Traditional endpoint monitoring provides little insight.
- Distributed tracing using OpenTracing allows tracing queries to monitor performance at the resolver level. Tools like Jaeger and plugins for Apollo Server and other GraphQL servers can integrate tracing.
- A demo showed using the Apollo OpenTracing plugin to trace a query through an Apollo server and resolver to an external API. The trace data was sent to Jaeger for analysis to help debug performance issues.
Taking Control of your Data with GraphQLVinci Rufus
The document discusses how GraphQL provides a solution for problems with traditional REST APIs by allowing flexible data fetching with one query. It summarizes pain points like over-fetching or under-fetching data and inconsistent features between platforms. The document then explains what GraphQL is, how it evolved from internal use at Facebook, popular brands using it, its specifications and implementations in different languages. It demonstrates how GraphQL enables flexible querying of data without versioning or multiple endpoints. The document also covers related tools like GraphiQL, schemas and types, and how GraphQL can be used with React. It concludes by discussing upcoming areas of focus like prioritizing data and supporting real-time updates.
GraphQL - The new "Lingua Franca" for API-Developmentjexp
Three years ago, with the release of the GraphQL specification, Facebook took a fresh stab at the topic of "API design between remote services and applications." The key aspects of GraphQL provide a common, schema-based, domain-specific language and flexible, dynamic queries at interface boundaries.
In the talk, I'd like to compare GraphQL and REST and showcase benefits for developers and architects using a concrete example in application and API development, data source and system integration.
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?
Real-time GraphQL API with minimum coding and maximum benefitMikhail Asavkin
There are many ways to build your GraphQL server in NodeJS. Some will require a lot of work, some will require almost no code at all. This time we'll focus on real-time GraphQL API or so-called 'live query' feature. We'll explore the best libraries and services to use to build your own real-time GraphQL API server, highlight some pros and cons and mistakes to avoid.
The document introduces GraphQL, including how it provides a common interface for client-server data fetching and manipulation. It discusses how GraphQL addresses issues with REST APIs like multiple round trips to the server.

Tech Talk on Microservices at SquareboatSquareboat
This document discusses moving from monolithic application architecture to microservices architecture. It describes how monoliths can be broken into modules and services using a service-oriented architecture (SOA) approach. SOA provides benefits like improved scalability, decoupling, and independent development and deployment of components. When implementing microservices specifically, each service should have its own data store rather than sharing data.

Custom Alexa skills allow developers to create skills that handle a wide variety of requests beyond the standard skills for smart home, video, music, and flash briefings. Custom skills have components like intents, utterances, an invocation name, and a cloud service endpoint. The interaction model defines the intents, sample utterances, and dialog model. Intents represent the requests a skill can handle and optionally have argument slots. A dialog model identifies the information a skill requires and prompts Alexa can use to collect it through a multi-turn conversation. Developers build custom skills by setting them up in the developer console, building the interaction model, coding and deploying an AWS Lambda endpoint service, optionally testing in beta, and submitting for certification.

How Valletta helped healthcare SaaS to transform QA and compliance to grow wi...Egor Kaleynik
This case study explores how we partnered with a mid-sized U.S. healthcare SaaS provider to help them scale from a successful pilot phase to supporting over 10,000 users—while meeting strict HIPAA compliance requirements.
Faced with slow, manual testing cycles, frequent regression bugs, and looming audit risks, their growth was at risk. Their existing QA processes couldn’t keep up with the complexity of real-time biometric data handling, and earlier automation attempts had failed due to unreliable tools and fragmented workflows.
We stepped in to deliver a full QA and DevOps transformation. Our team replaced their fragile legacy tests with Testim’s self-healing automation, integrated Postman and OWASP ZAP into Jenkins pipelines for continuous API and security validation, and leveraged AWS Device Farm for real-device, region-specific compliance testing. Custom deployment scripts gave them control over rollouts without relying on heavy CI/CD infrastructure.
The result? Test cycle times were reduced from 3 days to just 8 hours, regression bugs dropped by 40%, and they passed their first HIPAA audit without issue—unlocking faster contract signings and enabling them to expand confidently. More than just a technical upgrade, this project embedded compliance into every phase of development, proving that SaaS providers in regulated industries can scale fast and stay secure.
Scaling GraphRAG: Efficient Knowledge Retrieval for Enterprise AIdanshalev
If we were building a GenAI stack today, we'd start with one question: Can your retrieval system handle multi-hop logic?
Trick question, b/c most can’t. They treat retrieval as nearest-neighbor search.
Today, we discussed scaling #GraphRAG at AWS DevOps Day, and the takeaway is clear: VectorRAG is naive, lacks domain awareness, and can’t handle full dataset retrieval.
GraphRAG builds a knowledge graph from source documents, allowing for a deeper understanding of the data + higher accuracy.
