GraphQL Introduction
GraphQL IntroductionSerge Huber This document introduces GraphQL, describing what it is and isn't. It explains that GraphQL is not a query language like SQL, but rather specifies fields that can be resolved through code. The document provides examples of GraphQL schemas, queries, and mutations. It also discusses GraphQL integration with various technologies like Relay and Java libraries. Finally, it demonstrates GraphQL tooling like GraphiQL and an example DX integration.

Introduction to GraphQL
Introduction to GraphQLSangeeta Ashrit This document provides an introduction to GraphQL, including its history and key concepts. It discusses how GraphQL works with queries and mutations, schemas and types, validations and executions. Comparisons are made between GraphQL and REST. Examples of GraphQL queries and schemas are shown. Benefits of GraphQL include minimal code changes, no need for versioning, and handling client-specific data with one endpoint. Disadvantages include lack of "select *" and potential for large argument objects. Major companies using GraphQL are cited.

Graphql Intro (Tutorial and Example)
Graphql Intro (Tutorial and Example)Rafael Wilber Kerr GraphQL is an application layer query language developed by Facebook that allows clients to define queries for retrieving multiple resources from an API in a single request. It uses a type system and schema to define the data and operations available. GraphQL aims to solve issues with REST APIs like over-fetching and under-fetching data by allowing clients to specify exactly what data they need.
React & GraphQL
React & GraphQLNikolas Burk 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.
Introduction to GraphQL
Introduction to GraphQLBhargav Anadkat This document provides an overview of GraphQL, including:
- GraphQL allows clients to request specific data fields from an API rather than entire resources.
- It addresses limitations of REST such as multiple requests being needed to get related data.
- Many large companies use GraphQL including Facebook, GitHub, and Yelp.
- GraphQL has a type system including object, query, mutation, scalar and other types.
- Examples demonstrate basic GraphQL syntax and concepts like fields, arguments, and fragments.
- Additional resources are provided for learning more about GraphQL.
Better APIs with GraphQL 
Better APIs with GraphQL Josh Price - 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.

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
GraphQLCédric GILLET 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.
The Apollo and GraphQL Stack
The Apollo and GraphQL StackSashko Stubailo 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.

REST vs. GraphQL: Critical Look
REST vs. GraphQL: Critical LookNordic APIs GraphQL has made an excellent entree on the API scene. It is reintroducing the original concepts of RPC-style architecture with a revolutionary API consumer-oriented approach. It brought a new option to the stalled waters of RESTful APIs. But more importantly, GraphQL brought back the principal question: What is the right API architectural style for my project?
If you are building an API, this talk should give you enough of the theoretical background to make the right API-decision for your product.
In this talk, we will take a critical look at predominant API architectural style – RESTful APIs and put it in contrast to GraphQL and Hypermedia APIs. We will discuss the expected properties of distributed systems, the consequences of choosing a particular API style, and reflect these findings in the pros and cons of the popular methods.

GraphQL - The new "Lingua Franca" for API-Development
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.
Introduction to GraphQL
Introduction to GraphQLKnoldus Inc. GraphQL is a query language for your API, and a server-side runtime for executing queries by using a type system you define for your data.

Build, deploy and scale: Django, GraphQL and SPA (DjangoCon EU 2021)Dhilipsiva DS
After building, deploying and scaling a dozen on products with the Django + GraphQL + SPA (React) setup, we have come to understand what works and what does not. In this talk, I will share our findings on how to do the same.
I will be using a simplified StackOverflow clone for demonstration. First, I will introduce Python-Graphene (and few other related libraries), the library that is used to build GraphQL endpoints. Then the talk will focus on how to structure your Django GraphQL project. Share the toolchain (a few management command scripts) that are handy to export your constants & GraphQL schemas to be used with your SPA. Integrating with an SPA (React for demo purpose) Auth, API calls.
Then I will talk about how you go about deploying your API using 2 different strategies:
1. Docker compose / swarm (Vendor independent, non-production workloads)
2. AWS Fargate (Vendor dependant, production workloads, serverless containers)
And a cost-effective and highly scale-able deployment strategy for your SPA (using AWS S3, CloudFront and ACM).

Beginner's Guide to Frontend Development: Comparing Angular, React, Ember, an...Prasid Pathak
Over the past several years, as the role of the browser has grown, rich desktop-like apps have emerged built entirely in the browser. To enable this movement, a new generation of powerful JavaScript frameworks have emerged including EmberJS, AngularJS, BackboneJS, and React. In this 30 minute crash course on front end frameworks, Bloc co-founder and CTO Dave Paola will cover the history of front end web development, the recent emergence of these new Javascript frameworks, and go over some of the pros and cons for learning them.
We'll hear from Bloc co-founder and CTO Dave Paola and Bloc Developer Christian Schlensker. Prior to Bloc, Dave was a developer at Kontagent, has over 15 years of software development experience, and has founded numerous other companies. Christian comes to Bloc from Pinchit and TAG where he was a developer. Prior to that, Christian was also a graphic designer.
In our experience, beginners are often overwhelmed by buzz words like "HTML5," "JavaScript," and "Ruby." Without an experienced guide, they can spend months going down rabbit-holes drilling into specific languages, and emerge frustrated that they can't build a real website. Dave will start by helping you visualize the front end web development landscape.
Comparing Angular, Ember, Backbone, and React
2
Once you understand the landscape, Dave will introduce the four major front end frameworks that have emerged over the past two years. He'll discuss the pros and cons of learning each one, from the point of view of a beginner. These four frameworks are: AngularJS, EmberJS, BackboneJS, and ReactJS.

e2e testing with cypress
e2e testing with cypressTomasz Bak Cypress is an e2e testing tool that allows for testing web applications directly in the browser. It provides native access to the browser without using Selenium, making tasks like taking screenshots and recording videos possible. Some limitations are that it only supports single-page applications and one browser tab at a time. Cypress prioritizes developer experience through features like fast testing, intuitive debugging, and integration with continuous integration systems and dashboards. Many large companies have adopted Cypress for their e2e testing needs.
Working with npm packages
Working with npm packagesTomasz Bak The document discusses working with npm packages. It provides guidance on how to find suitable npm packages based on quality, GitHub activity, and downloads. It outlines steps for modifying existing packages such as forking the repository, making changes locally or as a pull request. The document also describes how to create and publish a new npm package by initializing it with npm, adding metadata to the package.json file, and publishing updates to npm.

JavaScript Promises
JavaScript PromisesTomasz Bak The document discusses JavaScript promises and how they can be used to handle asynchronous operations. Promises allow asynchronous functions to return values asynchronously by attaching callbacks to the promise object. This avoids callback hell and makes asynchronous code easier to read and maintain. The document covers how promises can be chained together, executed in parallel, cached, and passed around between functions. It also discusses promise implementations in different frameworks like jQuery, Angular, and how promises can interact across frameworks.
Replacing Rails asset pipeline with Gulp
Replacing Rails asset pipeline with GulpTomasz Bak The document compares the Rails asset pipeline and Gulp for asset management. Both tools concatenate and minify JavaScript and CSS files as well as support preprocessing with CoffeeScript and Sass. Gulp provides additional automated tasks like removing unused CSS, creating image sprites, and checking PageSpeed scores. Integrating Gulp into Rails can be done with plugins like gulp-rev-rails-manifest. The document provides examples of using Gulp for a Rails frontend to isolate assets, commit only installed dependencies to source control, and leverage native frontend package and build systems.

Is AI just another technology, or does it fundamentally change the way we live and think?
Every technology has a direct impact with micro-ethical consequences, some good, some bad. However more profound are the ways in which some technologies reshape the very fabric of society with macro-ethical impacts. The invention of the stirrup revolutionised mounted combat, but as a side effect gave rise to the feudal system, which still shapes politics today. The internal combustion engine offers personal freedom and creates pollution, but has also transformed the nature of urban planning and international trade. When we look at AI the micro-ethical issues, such as bias, are most obvious, but the macro-ethical challenges may be greater.
At a micro-ethical level AI has the potential to deepen social, ethnic and gender bias, issues I have warned about since the early 1990s! It is also being used increasingly on the battlefield. However, it also offers amazing opportunities in health and educations, as the recent Nobel prizes for the developers of AlphaFold illustrate. More radically, the need to encode ethics acts as a mirror to surface essential ethical problems and conflicts.
At the macro-ethical level, by the early 2000s digital technology had already begun to undermine sovereignty (e.g. gambling), market economics (through network effects and emergent monopolies), and the very meaning of money. Modern AI is the child of big data, big computation and ultimately big business, intensifying the inherent tendency of digital technology to concentrate power. AI is already unravelling the fundamentals of the social, political and economic world around us, but this is a world that needs radical reimagining to overcome the global environmental and human challenges that confront us. Our challenge is whether to let the threads fall as they may, or to use them to weave a better future.
