<html><body><h2>1. Introduction</h2><h3>What is Supabase</h3>Supabase is an open source founded in 2020 by Paul Copplestone and Jonathan Thornton. It provides developers with a set of tools to help them easily build web and mobile applications by handling common functionality like user management, data storage, and file hosting.Supabase manages all of the infrastructure and databases required so developers can focus on just building their applications. Some of the key features Supabase offers include user authentications, real-time synchronization, auto-generated APIs, dashboard and storage. Since it is open source, Supabase gives developers more transparency and control compared to other proprietary backend-as-a-service options. In just a couple years, Supabase has gained significant traction with developers who want a powerful but simplified way to create modern applications<h2>2. Features</h2><h3>Database</h3>Supabase database is built on top of PostgreSQL. It is an open source RDBMS which offers a reliable and scalable solution for various scenarios either small projects or enterprise applications. The database seamlessly integrates with Supabase’s authentication, storage and real-time services that will help developers to build a full-stack application more efficiently and quickly. Moreover, it provides powerful tools as web-bases like SQL editor, migrations, and APIs combine with built-in row-level security for data privacy and integrity without any extra configuration.<h3>Storage</h3>The Supabase storage service is built on Amazon S3, ensuring data redundancy, durability and automatic backups. The storage service offers a variety of authentication and authorization such as access control, row-level security policies, signed URLs for secure file access. It also supports real-time updates and notifications for file related events that will enhance the user experience.<h3>Authentication</h3>Supabase provides a comprehensive and flexible authentication system that will be tight with other services such as database or storage. It provides various authentication providers such as email/ password, 3rd parties providers (Google, Facebook…) and custom providers.The authentication allows easy association of user data with database records by implementing access control or row-level authentication. It offers built-in support for user management, password reset flows and email verification. Multi-factor is also provided by Supabase which is very flexible for developers to control their application access control flows.<h3>Realtime</h3>With PostgreSQL’s replication and streaming capabilities, real-time service immediately propagates database changes to connected clients for up-to-date data. It supports real-time subscriptions, allowing developers to define specific data for clients to subscribe to and receive automatic updates.<h3>Functions</h3>Developers can write Edge functions by Javascript or Typescript to manipulate content ( image optimization, compression, server-side rendering), caching strategies, security layers and many more use-cases. They offer user-friendly tooling for management, dashboard for monitoring, version control and much more.<h2>3. Pros &amp; Cons</h2>Supabase, as an open-source platform for building modern applications, offers a range of benefits and advantages, but it also comes with some potential drawbacks and considerations. Here are some pros and cons of using Supabase:<h3>Pros</h3><ul><li>Open-Source: Supabase is an open-source stage, which suggests that engineers can get to and adjust the source code as per their necessities. This advances straightforwardness, customization, and community-driven improvement.</li><li>Coordinates Administrations: Supabase gives a suite of firmly coordinated administrations, counting a database, verification, capacity, and real-time highlights. This integration rearranges advancement and diminishes the requirement for overseeing different third-party administrators.</li><li>Versatility: Supabase is built on the beat of battle-tested advances like PostgreSQL and Amazon S3, which are known for their adaptability and execution. This guarantees that applications built on Supabase can handle expanding workloads and activity without compromising execution.</li><li>Ease of Utilize: Supabase offers a user-friendly interface and tooling, making it simpler for designers to oversee and convey their applications, databases, and administrations.</li><li>Community Bolster: As an open-source extension, Supabase benefits from a dynamic and developing community of engineers who contribute to its advancement, give bolster, and share assets.</li></ul><h3>Cons</h3><ul><li>Seller Lock-in: Whereas Supabase is open-source, it depends intensely on exclusive administrations from Amazon Web Administrations (AWS), such as Amazon S3 and AWS Lambda. This could lead to potential merchant lock-in and expanded costs as the application scales.</li><li>Constrained Customization: In spite of being open-source, customizing and altering certain center components of Supabase may be challenging, particularly for less experienced engineers or those new with the fundamental advances.</li><li>Security Contemplations: As with any application that handles delicate information, engineers must be careful around executing legitimate security measures and taking after best hones when utilizing Supabase to guarantee information protection and security.</li><li>Learning Bend: Whereas Supabase points to simplify advancement, designers may still ought to familiarize themselves with the basic innovations and ideas, such as PostgreSQL, Amazon S3, and serverless capacities, which can have a learning bend</li><li>Dependency on Third-Party Services: Indeed in spite of the fact that Supabase gives a coordinated suite of administrations, it still depends on third-party administrators like AWS, which implies that any blackouts or issues with those administrations can possibly affect applications built on Supabase.</li></ul><h2>4.

This article will help you understand what Supabase is and how you can achieve it to build your application more robustly and efficiently by exploring it and creating a Todo app.

Supabase: Build an ready to published TODO app in just 30 minutes

<html><body><h2>1. Introduction </h2>In this article, I will guide you on how to build a simple UI with MAUI, including transition and mapping data. We will make a TODO app, which needs authentication, and then the main application where you can create/ edit, or mark the Todo task.The below mockup image will give you some hints about how the UI will look like<img src="https://api.careers.saigontechnology.com/storage/ck-editor/CKEDITOR-2fmIh4j7HwIeglTJ5uZnttqzbjayDvLsx64LN7O8.png" alt="Figure 1. TODO app’s UI Mockup">Figure 1. TODO app’s UI Mockup<h2>2. Screens</h2><h3>Sign In</h3>In the first screen, we will use the VerticalStackLayout to stack components vertically from top to bottom. We will use 2 Entry controls for Email and Password, and 3 buttons for Sign In, Register and Forget password.The Application’s title and “Forget Password” buttons will stick to the top and bottom respectively. The rest of the UI will stay in the middle when the height is increasing or narrowing.Let’s create a new ContentPage and name it “SignIn” in the folder “Pages” as in the image shown below:<img src="https://api.careers.saigontechnology.com/storage/ck-editor/CKEDITOR-cvoGEu1LXiXwnKjx7VnZsSBtB33vwMXPn0ObrKuZ.png">Figure 2. Sign In page’s contentWe modify the AppShell.xaml a little to make the application start from the page we created recently:<img src="https://api.careers.saigontechnology.com/storage/ck-editor/CKEDITOR-GYSfKrn3UdiLTaFOs3EPsEPQ32eyARlEvSuHiN1r.png">Figure 3. AppShell’s contentTo achieve the requirements stated above. We need to use StackLayout and divide the UI into 3 sections separately: Top, Middle, and Bottom<img src="https://api.careers.saigontechnology.com/storage/ck-editor/CKEDITOR-EI3FOI65lJGa1WpbTpo94Y6OyejXKhURnhpt1tvW.png">Figure 4. Sign In page’s structureNow, we add the Label control to the TOP section<img src="https://api.careers.saigontechnology.com/storage/ck-editor/CKEDITOR-ui1Z8G8OsuvWfNAFd4jxAfh40X27tvh5zejuJBJ9.png">Figure 5. Sign In page’s top sectionFor Email and Password inputs, we use Entry control to draw it in UI. Entry has a property named IsPassword, if we set it to True, the UI will hide what the user typed in as usual.<img src="https://api.careers.saigontechnology.com/storage/ck-editor/CKEDITOR-NWyA0c5at5djLLqmvdlKDjKhqym6CNTAewFKpoUY.png">Figure 6. Entry code examplesFor buttons, we use Button controls to achieve the click event. The event will be explained more clearly later in this article<img src="https://api.careers.saigontechnology.com/storage/ck-editor/CKEDITOR-yiiVTjc76gPg5Uqrko0gEkTc69xlATcYHRFW0dye.png">Figure 7.

The code behind it looks like thisLet's continue by adding some logic to the “Sign In” button. For example, we will display an alert if the user is not type in the Email or Password field; otherwise, we will navigate to the MainPage<img src="https://api.careers.saigontechnology.com/storage/ck-editor/CKEDITOR-3AqWjqFaAdOBS5Zb4ypvP0tqbu6sIhTTaFAS3GbU.png">Figure 10.

The Forgot Password page<h3>Main Page</h3>This is the main page of our application, where we will display the list of TODO. For demo purposes, we will add a button to simulate the add event to the list.This page utilizes the CollectionView to present a list of items. The appearance of each item is specified through the CollectionView.ItemTemplate. To enable scrolling in case the list is extensive, we enclose the entire content within a ScrollView.<img src="https://api.careers.saigontechnology.com/storage/ck-editor/CKEDITOR-ck1g9V875zPON288wsI9sXJt4rPXjA95eYHd0Uxy.png">Figure 15.

Navigation</h2>There are multiple ways to handle navigation in the MAUI app. For example: <ul><li>NavigationPage</li><li>Shell</li><li>TabbedPage</li><li>CarouselPage</li><li>Modal Navigation or URI-based navigation.   </li></ul>This article will show you how to use 3 common navigation<h3>NavigationPage: </h3>NavigationPage is a built-in navigation container that manages a stack of pages. You can push new pages onto the stack and pop them off to go back. It provides a navigation bar with a back button by default.<img src="https://api.careers.saigontechnology.com/storage/ck-editor/CKEDITOR-zmp4LRQtnyCJVRQFYrD0miKnSDQuWA1T11HdcHun.png">Figure 17.

Example code of how to access parameters at the destination page<h2>4. Design Pattern - Model-View-ViewModel (MVVM)</h2>MVVM stands for Model-View-ViewModel and is a design pattern commonly used in application development, including in .NET MAUI apps. MVVM provides a structured approach to separating concerns and organizing code in a way that enhances maintainability and testability.In the context of a .NET MAUI app, the MVVM pattern typically involves the following components:Model: The Model represents the data and business logic of the application.<img src="https://api.careers.saigontechnology.com/storage/ck-editor/CKEDITOR-Lj3QaxZKpUM7rgDL6w3UlunXJD6ihOkOlD6YNunF.png">Figure 24. TodoItem model classView: It defined how the application is presented to the user by defining controls, layout, and others<img src="https://api.careers.saigontechnology.com/storage/ck-editor/CKEDITOR-1MI989KmkhlOrrL5rtWHoMVtpbxsU2SE0tZJXhnm.png">Figure 25. View example ViewModel: plays a key role between View and Model. To connect and handle business logic in UI reactions<img src="https://api.careers.saigontechnology.com/storage/ck-editor/CKEDITOR-CMX22B6gWiwnPDzV1cM819A17P7wHdvdL25eMbyj.png">Figure 26. ViewModel exampleIn a .NET MAUI app, you typically use data binding and commands to establish the communication between the View and the ViewModel. The data binding mechanism allows the View to automatically update when the ViewModel's properties change, and commands enable the View to trigger actions in the ViewModel.By adopting the MVVM pattern in a .NET MAUI app, you can achieve a clean separation of concerns, easier testing, and improved code maintainability.</body></html>

This article will help you learn how to create a UI with MAUI layouts and controls. It also gives some tips when developing applications with MAUI

How to build UI with .NET MAUI

<html><body><h2 style="text-align:justify;">1. Introduction</h2>.NET MAUI stands for .NET Multi-platform App UI, which is a cross-platform framework for creating not only native mobile but also desktop apps with C# and XAML. This means that you can develop an application that can run on Android, iOS, macOS, and Windows from a single shared codebase..NET MAUI is open source with an MTI license and is the next generation of Xamarin.Forms. Its UI controls have been rebuilt to improve performance and extensibility. As a result, there are some similarities between .NET MAUI and Xamarin.Forms. The purpose of .NET MAUI is to enable you to implement as much of your app logic and UI layouts in a single codebase as possible..NET MAUI was released on May 23rd, 2022, and will follow the same monthly service schedule as the rest of .NET. It will retain the release schedule every 18 months that .NET developers have grown accustomed to.<h2 style="text-align:justify;">2. .NET MAUI Architecture</h2>From .Net 6, it has provided a series of platform-specific frameworks for creating apps: .NET for Android, for iOS, for MacOS and Windows UI (WinUI 3) libraries. These frameworks share the same .NET 6 Base Class Library (BCL). While BCL allows apps running on different platforms to share common business logic, the developer can define the user interface and models of how the elements of it communicate and interoperate. They can have separate UI for each platform separately, however, this approach requires you to develop and maintain a code base for each individual family of devices.The below diagram shows a high-level of the architecture of a .NET MAUI app:<img src="https://api.careers.saigontechnology.com/storage/ck-editor/image-rRE3uJikie3wsTghk4dKhWyZxAbloHhnw459qkqn.png">Figure 1. .NET MAUI architectureIn a .NET MAUI development, you write code that focuses on interacting with the .NET MAUI API (1). Then the framework directly consumes the native platform APIs (3). Moreover, the app code may directly interact with the platform APIS too, if needed. (2)Despite developing a .NET MAUI App that can be done on both PC and Mac, building apps for iOS and macOS still requires a MAC. Here is how a .NET MAUI app is compiled:<ul><li style="text-align:justify;">Android apps built using .NET MAUI compile from C# into an intermediate language (IL) which is then just-in-time (JIT) compiled to a native assembly when the app launches.</li><li style="text-align:justify;">iOS apps built are fully ahead-of-time (AOT) compiled from C# into native ARM assembly code.</li><li style="text-align:justify;">The app is built for macOS using Mac Catalyst, which brings your iOS built with UIKit to the desktop, and augments it with additional AppKit and platform APIs as required.</li><li style="text-align:justify;">Windows apps use the WinUI 3 library to create native apps that target the Windows desktop platform.</li></ul><h2 style="text-align:justify;">3. .NET MAUI Features</h2><h3 style="text-align:justify;">Modern development tools</h3>Create modern and innovative applications using the latest .Net 6 technology which is updated annually. The development environment supports both Mac and Windows. Another advantage is the large community of developers who are developing and contributing to .Net.<h3 style="text-align:justify;">UI controls for building application interface</h3>Maximize code reuse by not having to rebuild the entire UI for each platform you target. The framework will take care of this for you by applying XAML, built-in controls, and other advanced features. You can also customize controls yourself to be pixel-perfect and take advantage of the community by using third-party UI controls via the NuGet package manager.<h3 style="text-align:justify;">Cross-platform APIs for devices features</h3>You can use common shared APIs or take advantage of native performance by using specific APIs to control device sensors or unique features. For example, you can access MapKit, UIKit, SiriKit, etc., which are only available on iOS and macOS.

This series will introduce an overview of .NET MAUI and how you start to develop an application by using .NET MAUI. The first article will briefly cover what .NET MAUI is, how it behaves behind the scene, and some cool features of the framework.

&lt;html&gt;&lt;body&gt;&lt;h2 style=&quot;text-align:justify;&quot;&gt;1. Introduction&lt;/h2&gt;&lt;p style=&quot;text-align:justify;&quot;&gt;.NET MAUI stands for .NET Multi-platform App UI, which is a cross-platform framework for creating not only native mobile but also desktop apps with C# and XAML. This means that you can develop an application that can run on Android, iOS, macOS, and Windows from a single shared codebase.&lt;/p&gt;&lt;p style=&quot;text-align:justify;&quot;&gt;.NET MAUI is open source with an MTI license and is the next generation of Xamarin.Forms. Its UI controls have been rebuilt to improve performance and extensibility. As a result, there are some similarities between .NET MAUI and Xamarin.Forms. The purpose of .NET MAUI is to enable you to implement as much of your app logic and UI layouts in a single codebase as possible.&lt;/p&gt;&lt;p style=&quot;text-align:justify;&quot;&gt;.NET MAUI was released on May 23rd, 2022, and will follow the same monthly service schedule as the rest of .NET. It will retain the release schedule every 18 months that .NET developers have grown accustomed to.&lt;/p&gt;&lt;h2 style=&quot;text-align:justify;&quot;&gt;2. .NET MAUI Architecture&lt;/h2&gt;&lt;p style=&quot;text-align:justify;&quot;&gt;From .Net 6, it has provided a series of platform-specific frameworks for creating apps: .NET for Android, for iOS, for MacOS and Windows UI (WinUI 3) libraries. These frameworks share the same .NET 6 Base Class Library (BCL). While BCL allows apps running on different platforms to share common business logic, the developer can define the user interface and models of how the elements of it communicate and interoperate. They can have separate UI for each platform separately, however, this approach requires you to develop and maintain a code base for each individual family of devices.&lt;/p&gt;&lt;p style=&quot;text-align:justify;&quot;&gt;The below diagram shows a high-level of the architecture of a .NET MAUI app:&lt;/p&gt;&lt;p style=&quot;text-align:justify;&quot;&gt;&lt;img src=&quot;https://api.careers.saigontechnology.com/storage/ck-editor/image-rRE3uJikie3wsTghk4dKhWyZxAbloHhnw459qkqn.png&quot;&gt;&lt;/p&gt;&lt;p style=&quot;text-align:justify;&quot;&gt;&lt;i&gt;Figure 1. .NET MAUI architecture&lt;/i&gt;&lt;/p&gt;&lt;p style=&quot;text-align:justify;&quot;&gt;In a .NET MAUI development, you write code that focuses on interacting with the .NET MAUI API (1). Then the framework directly consumes the native platform APIs (3). Moreover, the app code may directly interact with the platform APIS too, if needed. (2)&lt;/p&gt;&lt;p style=&quot;text-align:justify;&quot;&gt;Despite developing a .NET MAUI App that can be done on both PC and Mac, building apps for iOS and macOS still requires a MAC. Here is how a .NET MAUI app is compiled:&lt;/p&gt;&lt;ul&gt;&lt;li style=&quot;text-align:justify;&quot;&gt;Android apps built using .NET MAUI compile from C# into an intermediate language (IL) which is then just-in-time (JIT) compiled to a native assembly when the app launches.&lt;/li&gt;&lt;li style=&quot;text-align:justify;&quot;&gt;iOS apps built are fully ahead-of-time (AOT) compiled from C# into native ARM assembly code.&lt;/li&gt;&lt;li style=&quot;text-align:justify;&quot;&gt;The app is built for macOS using&nbsp;&lt;strong&gt;Mac Catalyst&lt;/strong&gt;, which brings your iOS built with UIKit to the desktop, and augments it with additional AppKit and platform APIs as required.&lt;/li&gt;&lt;li style=&quot;text-align:justify;&quot;&gt;Windows apps use the WinUI 3 library to create native apps that target the Windows desktop platform.&lt;/li&gt;&lt;/ul&gt;&lt;h2 style=&quot;text-align:justify;&quot;&gt;3. .NET MAUI Features&lt;/h2&gt;&lt;h3 style=&quot;text-align:justify;&quot;&gt;Modern development tools&lt;/h3&gt;&lt;p style=&quot;text-align:justify;&quot;&gt;Create modern and innovative applications using the latest .Net 6 technology which is updated annually. The development environment supports both Mac and Windows. Another advantage is the large community of developers who are developing and contributing to .Net.&lt;/p&gt;&lt;h3 style=&quot;text-align:justify;&quot;&gt;UI controls for building application interface&lt;/h3&gt;&lt;p style=&quot;text-align:justify;&quot;&gt;Maximize code reuse by not having to rebuild the entire UI for each platform you target. The framework will take care of this for you by applying XAML, built-in controls, and other advanced features. You can also customize controls yourself to be pixel-perfect and take advantage of the community by using third-party UI controls via the NuGet package manager.&lt;/p&gt;&lt;h3 style=&quot;text-align:justify;&quot;&gt;Cross-platform APIs for devices features&lt;/h3&gt;&lt;p style=&quot;text-align:justify;&quot;&gt;You can use common shared APIs or take advantage of native performance by using specific APIs to control device sensors or unique features. For example, you can access MapKit, UIKit, SiriKit, etc., which are only available on iOS and macOS. Or you can use shared APIs across devices such as Battery, Email, Geolocation, Accelerometer&hellip;&lt;/p&gt;&lt;h3 style=&quot;text-align:justify;&quot;&gt;Single project&lt;/h3&gt;&lt;p style=&quot;text-align:justify;&quot;&gt;Take advantage of shared resources such as images, fonts, platform-specific features, and business logic in a single codebase. Or you can guide how it compiles for the targeted platform easily.&lt;/p&gt;&lt;h3 style=&quot;text-align:justify;&quot;&gt;Full App Platform&lt;/h3&gt;&lt;p style=&quot;text-align:justify;&quot;&gt;The framework provides Pages, Layouts, and Controls for building UI using C# and XAML. It also includes two-way binding, navigation, state management, animation, dependency service, platform API, theme, and more.&lt;/p&gt;&lt;h3 style=&quot;text-align:justify;&quot;&gt;Blazor hybrid and .NET MAUI&lt;/h3&gt;&lt;p style=&quot;text-align:justify;&quot;&gt;We can combine both technologies to build not only web but also native applications. MAUI will use shared Blazor components or mix between them to build a complete application.&lt;/p&gt;&lt;h2 style=&quot;text-align:justify;&quot;&gt;4. XAML&lt;/h2&gt;&lt;p style=&quot;text-align:justify;&quot;&gt;&lt;img src=&quot;https://api.careers.saigontechnology.com/storage/ck-editor/image-F5zXEvjeNuc38itSLuhfSU8eihLahKlHRcelGvoy.png&quot;&gt;&lt;/p&gt;&lt;p style=&quot;text-align:justify;&quot;&gt;&lt;i&gt;Figure 2. An example of a XAML file&rsquo;s content&lt;/i&gt;&lt;/p&gt;&lt;p style=&quot;text-align:justify;&quot;&gt;The XAML stands for eXtensible App Markup Language. It is a declarative and very powerful language for not only defining the UI of the application but also handy for data binding and navigating the app. The XAML will come with a C# code behind the file, both defining the same partial class.
