In this tutorial, I am going to create a sample application to show how to use local JSON files in an Angular application. There are different ways to read local JSON files in Angular. we’ll see different ways to read local JSON files in Angular for example. It turns out there are at least a couple of ways to do it. I will mention the most common ones: 1. Using the import statement 2. Using Angular HttpClient Step 1: Create a new Angular Project Create an angular project using the CLI com
Micro Frontends are a way to build and deliver a large application as a composition of small, independent applications. This approach enables teams to work on their own codebases and deliver new features faster, while also making it easier to scale development. Module Federation is a way to implement Micro Frontends in the Angular ecosystem. It allows multiple Angular applications to share a common set of libraries and enables them to communicate with each other using a shared API. Benefits
What is a Standalone Component? A Standalone component is a type of component which is not part of any Angular module. Prior to angular v14, usually when you would create a component, you’d pass it inside in the declaration array of the module. If you would not do that, Angular would complain about it and not compile but from Angular v14, you can create standalone components which are independent of modules. Apart from components, you can also create standalone directives and pipes. In this bl
For business organizations, it is necessary to get hold of mobile app requirements before finalizing the app development framework. React Native Vs Angular are leading app development frameworks. See the important factors that determine their selection.
Introduction Angular is, by default, a fast and performant framework. While it leaves ample space for improvement by opting out some of its magic, we almost never have to do anything special to write extremely performant code for the average app. With that said, some difficulties will eventually arise when we are writing either performance-critical apps, apps with large and complex content, or apps updated extremely frequently. There are loads of resources and popular advice out there about i
What is Lazy Loading? Lazy loading (also called on-demand loading) is an optimisation technique for the online content, be it a website or a web app. * Instead of loading the entire web page and rendering it to the user in one go as in bulk loading, the concept of lazy loading assists in loading only the required section and delays the remaining, until it is needed by the user. * By default, NgModules are eagerly loaded, which means that as soon as the app loads, so do all the NgModu
Why Do We Need Server-side Rendering? Angular applications are client-side applications that execute on the browser - which means they are rendered on the client, not on the server. You can add server-side rendering to your app using Angular Universal. There are two main reasons to create a server-side version of your application: * Performance: Rendering Angular on the server-side improves the performance of your application, particularly on mobile and low-powered devices since the bro
Internationalization (i18n) is the process of designing and preparing your app to be usable in different locales around the world. Localization is the process of building versions of your app for different locales, including extracting text for translation into different languages, and formatting data for particular locales. A locale identifies a region (such as a country) in which people speak a particular language or language variant. The locale determines the formatting and parsing of dates,
New Breaking Changes in Angular 10 * Typescript version <= 3.8 are no longer supported. Please update to Typescript 3.9. * Input fields of type ‘number’ fire the ‘valueChanges’ event only once per value change (as opposed to twice in some cases) * UrlMatcher can now return ‘null’ values. * The ‘minLength’ and ‘maxLength’ validation only validate values that have a numeric length property. Angular Update Guide 9.0 -> 10.0 for Basic Apps Before Updating * If you depend on many Angu
Angular elements are new HTML custom elements which are angular components packaged as custom elements. Custom elements or web components give developers the ability to extend and create their own tags.It can be used without any dependencies. So you can use your custom elements in your React, Angular and Vue applications. You can also use it with your backend. All the advantages of web components applies in Angular elements. Why do we need it? If your Application is small, then you can mana
Technology has a way of evolving continuously. Based on how it keeps changing, user behavior and web based apps too continue to change. Programming languages and tools are most certainly directly affected by these changes. What may be the most popular language today may be a forgotten story tomorrow. Each day, a new enhancement threatens to turn a familiar language or framework archaic and obsolete. While out of the two that we are about to discuss in today’s blog none have been pushed over to t
There is no doubt about the fact that reminiscing on older simpler days is always sweet. However, while life was simpler earlier, today things have gotten a lot more interesting and, well, let’s just say, spicy! Creativity has reached another level and each day a new innovation in technology and the general blue nowhere bedazzles us. Websites are no longer simple static pages aimed at sharing information in plain text format with a little graphics sprinkled here and there. Form and functionalit
Nowadays we need everything to be automated. So whenever we speak automation, the first impression is that everybody says about CI/CD. Now the Questions is What they are and How they work. I will just go through a little reference for the both of it for the people who are new to this Topic CI i.e Continuous Integrations It is a process for continuously building and testing software using an automated process. CD i.e Continuous Deployment. It is a process for automatically deploying new softwa
What is Pre-rendering in angular? Pre-rendering creates a static page when we build an angular application. As a result, the website will load faster and will be SEO-friendly without the need for server-side rendering. The pre-rendering is helpful if we want to serve static pages in the application. Why should we pre-render Angular applications? Most of the obstacles that one faces with an Angular application are fixed by following the optimization techniques. Although there are still a few
What is Interceptor in angular? Interceptors provide a mechanism to intercept and/or mutate outgoing requests or incoming responses. They are very similar to the concept of middle-ware with a framework like Express, except for the front-end. Why do we use interceptors? Interceptors can be really useful for features like caching and logging. Interceptors are a way to do some work for every single HTTP request or response . * Add a token or some custom HTTP header for all outgoing HTTP requests
Component Development Kit (CDK) The Component Development Kit is a set of tools that implement common behaviors and components with very unique interaction styles without being opinionated about the template choices. It is a kind of abstraction of the Angular Material Library, with no styling specific to material design. It provides more unique ways to get creative while building your angular components. Drag and Drop Tool The Drag and Drop tool is one of the component development kit common
The world, courtesy of the IT industry, has seen a large number of technological breakthroughs in the past decade. One might wonder, what next? With numerous technologies emerging every year, the software development industry has experienced exponential growth.
Let’s face it. There is no escaping web and mobile apps. Whether you’re a one-person company, a small-medium enterprise, a startup or a large corporation, you’ve got to be mobile! Actually, not just mobile but, your online presence and functionality have got to be top-notch also.
As node developers, we all know what the require() function does. But how many of us actually know how it works? We use it every day to load libraries and modules but its behavior is still a mystery for us, so let’s solve this mystery.
