However, this results in creating a lot of...
GraphQL is a query language for your API. It simplifies the process of requesting the server by providing convenient ways to query objects. For instance, if you’re using a REST API and you need a list of books, you might hit the GET /books/list endpoint for all books. Then if you need a specific book by ID, you would hit GET /book?id={id}, which means you’ll be making multiple requests to the server. But GraphQL does something called declarative data fetching, where you can ask for what you want and get a predictable result in a single request. Awesome right? Let’s see how it all works. What we will be learning? In this article, you’ll learn the basics of GraphQL by using the Laravel GraphQL package to build a server that does the following: Before we get started, let’s go over some GraphQL fundamentals. What is a GraphQL Schema? A GraphQL schema describes queries, mutations, and types associated with it: In the code above, the exclamation mark on column names such as id, name, and email means that they are required fields. You can also define various data types such as Int, String, and so on. You can also include list types and define the data type it should contain like with hobbies. What are GraphQL Queries? GraphQL makes it convenient to interact with data on an object. You use methods to ask for specific fields on objects and then get the expected results: What are GraphQL Resolvers? Every time you request data from a GraphQL server, it gets resolved. Resolvers contain arguments such as an object, args, context, and...

Functions of procedural programming can control variables while other functions return value. Functional...
This article shows how to implement an ASP.NET Core Razor page to authenticate against Azure B2C and use Web APIs from a second ASP.NET Core application which are also protected using Azure B2C App registrations. Azure B2C uses the signin, signup user flow and allows identities to authenticate using an Azure AD single tenant. Two APIs are implemented, one for users and one for administrators. Only identities from the Azure AD tenant can use the administrator API. The authorization implementation which forces this, is supported using an ASP.NET Core policy with a handler. Code: https://github.com/damienbod/azureb2c-fed-azuread Setup The ASP.NET Core applications only use Azure B2C to authenticate and authorize. An ASP.NET Core Razor page application is used for the UI, but this can be any SPA, Blazor app or whatever the preferred tech stack is. The APIs are implemented using ASP.NET Core and this uses Azure B2C to validate and authorize the access tokens. The application accepts two different access tokens from the same Azure B2C identity provider. Each API has a separate scope from the associating Azure App registration. The Admin API uses claims specific to the Azure AD identity to authorize only Azure AD internal users. Other identities cannot use this API and this needs to be validated. The Azure B2C identity provider federates to the Azure AD single tenant App registration. Setup Azure B2C App registrations Three Azure App registrations were created in Azure B2C to support the setup above. Two for the APIs and one for the UI. The API Azure App registrations are standard with just a scope definition. The scope access_as_user was exposed in...
