Conversely, interop goes both ways. In that mode Blazor does not compile C# to WebAssembly, instead it runs C# on the server-side and communicates HTML via SignalR, similar to AJAX UpdatePanels in WebForms (remember those?). Using web components in Angular applications and components is as straightforward as using Angular components. If you want separate view and component files you have to know to add a "code-behind" of the correct name and make it partial. First, Adding a new component, directive, or pipe in Angular is easy with the Angular CLI. AngularJS is a renowned web application framework used for creating dynamic single page application by using dynamic codes. If you're starting a new project choose your execution model up front, don't plan on switching. What's beautiful about it: I was able to get it to run client-side for offline support in single player mode or entirely server-side with SignalR callback events when run in multi-player mode. Change Detection now works on IE as expected. If that sounds exiting, it is. I'll compare them across ten categories where I feel their differences are interesting and might affect a project's technology choice: First I'll give a quick overview of the Blazor WebAssembly technology, in case you've missed it. I'm certainly no Blazor expert at this point, but I've sunk about 40+ hours into building the game, and after working professionally in Angular 2+ apps for the last two years I feel comfortable comparing the technologies and sharing my feelings. Announced in 2017, officially released just a couple months ago on May 19, 2020, Blazor WebAssembly is a technology that allows developers to write client-side code in C# and Razor (a pleasant hybrid of HTML and C#) and have it compile down to WebAssembly. ... right now all we need to know is that this option allows us to see further inside our web page, including inside a plain HTML input. ag-Grid is the industry leading JavaScript datagrid. If the game sounds fun check it out at typershark.io (keep your expectations low). Angular has been designed from the ground up to work with Web Components. That scenario seems far less likely given the massive JavaScript ecosystem, so I'll have to give the win to Angular. I find RxJS to be overkill and obtuse in 99% of scenarios. Everything Blazor provides is an interface for mockability, and dependency injection is a first class citizen. Angular: Angular, on the other hand, has its command-line interface or CLI that generates components, services, and more, which also helps to complete projects faster and efficiently. Therefore at page startup time and before Angular gets a chance to kick in, the Angular expression will be passed to the component which would act upon it directly, like the image element immediately loads the image using the url provided. Our team took on this concept recently with one of our most engaging and involved projects, and it worked like a charm. Before I can get to the categories I'll introduce a little code to ground the conversation. And, of course, this approach was also a hell in terms of software development process, which required me to run a Gulp script, rebuild the ASP.Net app and hard reload the page every time I changed a tiny bit of CSS. Either way Blazor is bright and shiny and fun to work with today, and it has an even shinier future ahead. It extends existing HTML by providing directives. Here are all the differences between Angular VS React: React uses a Virtual DOM, Angular operates on a real DOM. That's the primary question I set out to answer when I built typershark.io, a simple web based single or multi-player co-op game that I built to help encourage typing for my daughter and simultaneously to learn Blazor. A couple of things to note: 2. I simply could not return to a framework without it at this point. First, we’re going to create a new Angular app and a simple widget. Ok, I lied, one more word on this. Angular can simplify the management of these components. If we look inside it, we will see a typical Angular app: a main.ts file, an app.module, an app.component and other stuff. For the most part, you would use Web Components as leaf node components, and Angular for views and other composite components. It sends notifications out like: SharkAdded, GameOver, or GameChanged. This code will take the form of a component. If I were to associate each HTML tag with a person (and I should definitely copyright this idea), iframe would end up being an old great-grandma who has been around since the last century and persistently does a decent job of forgetting your name and falling asleep at random times, so everybody kind of got used to it. Not so fast. Web Components and Angular 2.0. So, this command creates a projects folder inside our root directory, and in it there will be a folder named FirstWebComponent. By comparison an Angular PlayerName component feels very similar: And here's how to use the component in angular: The template code looks pleasant (it is, I actually really like Angular views and data binding syntax), but before runtime there's very little syntax validation, and certainly no type checking. I love that. The important thing to understand about Angular Components turned into Web Components is that they are simple Angular components — nothing about them has to be different to use as Web Components. For example, we know tags like div, span, and others. Angular VS React. Once you have installed polyfills for older browsers, you can use Web Components interchangeably with Angular components. But what about the bane of all web developers — IE? I know this will be fixed soon, but it is very frustrating now. First, Adding a new component, directive, or pipe in Angular is easy with the Angular CLI. If we open our app in which we use a Web Component, we will see that our button-with-counter has successfully been rendered. Probably, for most of front-end developers, Angular is a well known framework made for building web applications. What does that mean? Overall tooling was a big win for Angular, but stay tuned, I bet Blazor will come out strong in the next version. If you're interested in more details about how I built it keep an eye on my blog and/or subscribe to Code Hour. It simplifies the generation of different versions of the same project but different platforms with linting, dynamic type checking, and more. You can do anything inside them which you could do with a … According to StackOverflow's 2019 developer survey C# is the 10th most loved language while TypeScript is 3rd. No, thankfully, there is a simple workaround. But if we only have access to compiled files, we can include them with the scripts field in our angular.json file in the target project, and add schemas: [CUSTOM_ELEMENTS_SCHEMA], to our app.module.ts file. Luckily, Angular makes this really easy. It has a core engine that produces sharks, tracks active sharks, figures out when sharks have timed out, and tracks which users (assuming multi-player mode) have typed which elements of the sharks. Here's the Blazor code for a GetPlayerName component that can accept a default player name (perhaps pulled from local storage), prompt the user for the name, and upon submission will return the name the player provided: That can then be used from a parent component like this: Check out the EditForm element on line 1 of the PlayerNameComponent, with its Model attribute. In our case, we will just be presented with a blank screen and no errors — a mystery to investigate and get frustrated about. Passionate about WebDev, Football, Chess and Music. There are several important things to notice: When we look inside the dist folder, we will see the following: These are the files we need to include in another app to be able to use our Web Component. Twice a month. This was a big frustration of mine. Lets have a look at its internal implementation using the Dev Tools: That's right, at least in this case an HTML input is really not a leaf element ! While Angular components work by … Next, while IntelliSense worked great inside of forms, I found it frequently failed to find built-in components like the aforementioned ValidationSummary, which I had to know about and copy-paste in. First things first, we are going to start a new Angular app. Use of Directives between Angular vs AngularJS The amount of flexibility offered in the reactive forms model (as opposed to the template driven forms approach I showed above) provides a huge advantage and I couldn't find anything comparable in Blazor (although as with everything Blazor I'm new at this, please write in the comments if I missed something). Debugging (and error messages in general) is a bit of a problem in Angular Web Components. Take another look at Blazor's AddPlayerComponent from the perspective of validation. That makes refactorings more dangerous, and IntelliSense virtually useless. We are happy to announce that we published our big Angular component library into open source! AngularJS – or as some may prefer: Angular 1 – was created in 2009. Last year I was tasked to incorporate several Angular components into an existing ASP.Net application. Simply ng generate component MyNewComponent and you have a component class, view template, CSS/LESS/SCSS file and a test file, and Angular registers it for you. In my next article, we will start diving into this scripts to make our development process way more fun. typershark.io can run in single player mode or multi-player mode. I'll be keeping a sharp on it, if you've read this far you definitely should too. If the code sounds interesting check it out on github (I accept pull requests). You were expecting me to give Blazor the win because of strong typing and IntelliSense in forms? So, should we forget about Web Components on IE? I'll assume you have a minimal grasp of Angular. We will wind up with an empty Angular app. First, we will create an Angular project using the Angular CLI. Other approaches available to us using IVY. They have predefined behavior, and may be used in different places of our view. Web components offer substantial potential for component interoperability across frameworks. So validation is a win for Angular, but in its simplicity, Blazor's got game. There are a handful of important characteristics to look at here, chief of them being overall size and load times, the components available, and learning curve. Angular uses both one-way and two-way data binding, while React uses the only one-way binding. Please note that Angular Materialfor Angular 1.x is a distinct entity from Angular Material2 for Angular 2+. Also Material Components for the Web are distinct from Polymer's Material/Paper Elementswhich are standards-based Web Components. There is a small package with exactly what we want: And slightly change our app.module.ts file: Here we just invoked the ElementZoneStrategyFactory constructor, got a new strategyFactory and passed it on to the createCustomElement function along with the injector. A senior software developer at InfernoRed Technologies with a passion for .Net development, open source software, continuous integration, building cross platform mobile apps, and hardware hacking.
