GraphQL is a query language in which we send the query to the GraphQL Server. The server executes the query at runtime for fulfilling those queries with your existing data.

Let’s me make you understand this in more easy words. I suppose that you know SQL (Structured Query Language). If we are having a user table with the information about their name, age, email, phone. Now you want to fetch the name and email of the user then you will write a query for that and you will get that information. (Select name, email form the users).

You will not get age and phone of the user because you have not asked for that information. These are a thing of the server-side (backend). If you are a frontend developer and you had made 20 pages where you need users information. You will ask the backend developer that I want user information on different pages so I need an API. Backend developer will make API will give you an endpoint.

> on 6 pages you want user’s name only

> on 10 pages you want user’s email and name

> on 4 pages you want user’s name email and phone.

So you backend developer may apply two approaches.

• He will make 3 different endpoints with different data.
• He can make a common API with all the information.

What is the problem with these two approaches?

• We are having multiple endpoints. If someday we will ned user’s name and age then we need to make another endpoint.
• We are not having multiple endpoints but we are over fetching the data, on each page we don’t want the user’s phone still we are getting the data.

GraphQL is a query language for API’s. It shows what are the different types of data provided by the server and then the client can pick exactly what it wants.

Also in GraphQL you can get multiple server resources in one call rather than making multiple REST API calls.

You can check out https://graphql.org/ for the full list of benefits.

The thing is until you see GraphQL in action, it’s hard to understand the benefits. So let’s get started with using GraphQL.

We will be using GraphQL along with NodeJS in this article.graphql node

GraphQL is a relatively new technology developed initially at Facebook and open-sourced to the world in 2015. In 2017, it really took off and made the leap from a cool, niche technology to one of the primary ways companies like Walmart and IBM are starting to work with their APIs and data.

If you're new to GraphQL, here's a definition that sums it up nicely.

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. GraphQL isn't tied to any specific database or storage engine and is instead backed by your existing code and data. (Source: graphql.org)

The last sentence is an important one to be mindful of when getting started with GraphQL. So, I'll repeat it by saying GraphQL is not any specific framework or database but rather a specification that describes the capabilities and requirements of data models in client‐server applications. There's a growing number of libraries out there to help you implement the GraphQL spec in your app for a number of different languages.

In this post, we'll learn about designing and building a GraphQL powered API using ASP.NET Core 2, Entity Framework Core and Joe Mcbrides's excellent graphql-dotnet library.graphql

Graphing network evolution….

With Flutter gaining popularity among the developers, its a beginning of a new era. Things evolving, being accepted or rejected and again evolving, its always been a

Build Fast, Fail Faster era….

One of the evolving and gaining popularity topics between the masses is Graph QL.

What’s GraphQL…

“What?!”, you say. “GraphQL is a server side query language. Redux is a client-side state management library. How could one replace the other?” Good question.graphql redux

So you’ve been constructing and using REST API’s for quite some time now and short while ago started hearing about GraphQL — a new hype in the field of API technologies. Some says it’s good, some says it’s not. Well, I am pretty sure you all must be wondering about what this GraphQL fuss is all about and how it’s different from the traditional approach.

The purpose of this article is to highlight the major features associated with GraphQL along with discussing the significant pros and cons associated with this particular API specification.graphql

GraphQL servers send your app into the world wearing only its birthday suit — everything is exposed. A quick introspection query reveals all possible API operations and data structures. That could change, but for now, all of your operations and data are laid bare.

Therefore, one might anticipate authentication and authorization are GraphQL first class citizens. But, neither of them are part of the official spec. That lack of direction created a lot of sleepless nights for my GraphQL server development, and it wasn’t until I watched Ryan Chenkie’s talk about directive permissions that I found a solution.graphql

Recently, there have been a lot of exciting developments happening in the GraphQL client space. Some of these new clients, such as urql and micro-graphql-react, were partially born from the idea that Apollo should be easier to get started with, especially for beginners. We’ve taken this constructive feedback to heart — that's why today, we’re announcing apollo-boost, an easy-to-use booster kit for Apollo Client with our recommended configuration. graphql react

• Part I: Setup and displaying short URLs using GraphQL (this post)
• Part II: Creating short URLs
• Part III: Creating serverless function for hashing
• Part IV: Short URL stats (number of clicks, etc.)
• Part V: User authentication

Part I: Setup and displaying short URLs using GraphQL

In this series of post I’ll explain how to build a simple URL shortener using React, Apollo and GraphQL (Graphcool). GitHub repo the project is located here.

The idea behind the URL shortener is simple — the shortener takes a long URL such as www.example.com/thisisalongurl and shortens it to http://goo.gl/ABC. When shortened URL is accessed, the service expands it to the original URL and redirects you there. The algorithm I’ll use to calculate the hash (short URL) is explained here.graphql react

An open-source GraphQL API layer for your database

Today we are incredibly excited to announce Prisma (previously referred to as Graphcool 1.0).

Prisma is a GraphQL database proxy turning your database into a GraphQL API. You can use the API as foundation for your own GraphQL server or connect directly from your frontend application.graphql

Apollo Client, a powerful and flexible GraphQL client library, just reached version 2.0. In this post, we want to highlight some of the major changes compared to the previous release.graphql

Graphcool is a great service. We got a chance to put it through the paces on a recent React Native project, and I was impressed. Graphcool began as a GraphQL Backend-as-a-Service and recently released the (open source!) Graphcool Framework. The Graphcool Framework manages to bring an instant GraphQL backend to your local machine with minimal effort on your part. All you have to do is define the schema.

Running the Graphcool Framework locally enables you to easily manage your project and develop apps the way you’d develop anything else — using your favorite editor and git. When you’re ready to deploy, you can host the API yourself or use Graphcool’s hosted infrastructure.

Let’s take a look and see how easy it is to get going.graphql react

What are GraphQL fragments? What are UI components? Why are they a match?

To build anything complicated, the one and only truly helpful strategy is to split what needs to be built into smaller parts and then focus on one part at a time.

Ideally, those parts should be designed in a way that does not couple them with each other. They should be testable on their own and they should be reusable. The big complicated system should be the result of putting these parts together and having them communicate with each other to form features.

With User Interfaces, one strategy to do this splitting is by using UI components.graphql test

This is the second and final part of a series where I cover how to setup authentication with React Native, GraphQL, and MongoDB. In part 1 we setup the server.

In this part we’ll be building a basic React Native app and connecting it to the backend. We’ll be using Snack to do this so you never have to leave your browser.graphql react

I’ve been playing with Apollo a lot lately and, as with nearly any app, I needed to add authentication to that app. I looked around but couldn’t find any posts specifically on the subject of authentication using React Native, GraphQL, and MongoDB — so that’s what we’ll be covering today.

In part one of this series you’ll learn how to configure the server (using GraphQL/Apollo, Mongo, Express, and JSON Web Tokens). In part two we’ll setup the React Native client to interact with it all.

The app we’ll be building is very simple, but will demonstrate the critical pieces of an authentication flow. It will have 3 screens:

• Login
• Register
• Log out

Ready? Let’s go.graphql react

GraphQL is a query language that offers a compact way to read and write relational data between the client and the server. It allows developers to ask for the exact information they need, without receiving any unnecessary data.

In this article we've prepared for you a collection of great resources for learning GraphQL. The lessons are separated into 3 categories, depending on your experience and knowledge with the new query language.graphql

Apollo Client is the ultra-flexible, community-driven GraphQL client for React, Vue.js, Angular, and other JavaScript platforms. You just describe your data requirements with a GraphQL query, and Apollo Client fetches and manages the data for you.

It’s used in production by companies like KLM, IBM, Intuit, and more, and is built with contributions from engineers at companies like Coursera, Convoy, and even Microsoft! With over 2 million downloads so far, Apollo Client is the most popular way to use GraphQL in your app.microsoft graphql react javascript unity
