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...
These days, all kinds of on-demand services are available for people with the help of smartphone apps. We are living in a world, where on-demand applications are getting popular.

Command line tools are one of the most popular applications we have today. We use command line tools every day, and they range from git, npm or yarn. Command line tools are very fast and useful for automating applications and workflows. We will be building a command line tool with Node.js and Fauna for our database in this post. In addition, we will be creating a random quotes application using Node.js, and add permission and a keyword for our app. To take full advantage of this tutorial, make sure you have the following installed on your local development environment: Getting Started with Fauna Register a new account using email credentials or a GitHub account. You can register a new account here. Once you have created a new account or signed in, you are going to be welcomed by the dashboard screen: Creating a New Fauna Instance To create a new database instance using Fauna services, you have to follow some simple steps. On the dashboard screen, press the button New Database: Next, enter the name of the database and save. Once a database instance is set up, you are ready to access the key. Use access keys to connect authorization and a connection to the database from a single-page application. To create your access key, navigate to the side menu, and go to the Security tab and click on the New Key button. Creating a Collection Navigate to your dashboard, click on the Collections tab from the side menu, press the New Collection, button, input your desired name for the new collection, and save.

Building A Google Password Manager Clone With React JS and Fauna Authored in connection with the Write with Fauna program. This article will walk you through how I built a password manager with React JS and Fauna. Password managers are essential. When we have multiple accounts and multiple passwords, we need to keep track of them. Tracking passwords is difficult without having a password manager to help you. Prerequisites Getting Started With Fauna First, create an account with Fauna. Creating A Fauna Database To create a fauna database, head to the fauna dashboard. Next, click on the New Database button, enter the database name, and click enter. Creating Fauna Collections A collection is a grouping of documents(rows) with the same or a similar purpose. A collection acts similar to a table in a traditional SQL database. In the app we’re creating, we’ll have two collections, users and passwords. The user collection is where we’ll be storing our user data, while the passwords collection is where we’ll be keeping all the password data. To create these collections, click on the database you created, click New Collection. Enter only the collection name (users), then click save and do the same for the second collection (passwords). Creating Fauna Indexes Use indexes to quickly find data without searching every document in a database collection every time a database collection is accessed. Indexes can be created using one or more fields of a database collection. To create a Fauna index, click on the indexes section on the left of your dashboard. In this application, we will be creating the following indexes: Setting Up The...

In this article we will be exploring Unit of work and Repository pattern with EF Core and .Net 5. You can watch the full video on Youtube: Please find the source code on GitHub: https://github.com/mohamadlawand087/v33-repo-uow So what we will cover today: As always you will find the source code in the description down below. Please like, share and subscribe if you like the video. It will really help the channel What is a Repository Pattern The repository pattern is talked about a lot, especially in the API-and-microservice-heavy world that .net core shines in. The repository pattern is a strategy for abstracting data access layer. So what is a data layer? it is made up of the code in the application that is responsible of storing and retrieving the data. Adding, removing, updating, and selecting items from this collection is done through a series of straightforward methods, without the need to deal with database concerns like connections, commands, cursors, or readers. Using this pattern can help achieve loose coupling and can keep domain objects persistence ignorant. Why use Repository Pattern There are many reasons why we want to use code absatractions What is Unit of Work (UoW) If the Repository pattern is our abstraction over the idea of persistent storage, the Unit of Work (UoW) pattern is our abstraction over the idea of atomic operations. It will allow us to finally and fully decouple our service layer from the data layer. The unit of work pattern now manages the database states. Once all updates of the entities in a scope are completed, the tracked changes are played onto the database in...
