Version 7 of Angular — CLI Prompts, Virtual Scroll, Drag and Drop and more

Version 7 of Angular — CLI Prompts, Virtual Scroll, Drag and Drop and more
The 7.0.0 release of Angular is here! This is a major release ning the entire platform, including the core framework, Angular Material, and the CLI with synchronized major versions. Virtual Scrolling can improve the performance of applicationsHow to update to v7
Visit update.angular.io for detailed information and guidance on updating your application, but thanks to the work we did in v6, updating to v7 should be one command for most developers:
ng update @angular/cli @angular/coreEarly adopters of v7 have reported that this update is faster than ever, and many apps take less than 10 minutes to update. CLI Prompts
The CLI will now prompt users when running common commands like ng new or ng add @angular/material to help you discover built-in features like routing or SCSS support. StackBlitz 2.0 Supports multipane editing and the Angular Language ServiceAngular Console — A downloadable console for starting and running Angular projects on your local has a new home on npm, and has its first stable release for Angular
NativeScript — It’s now possible to have a single project that builds for both web and installed mobile with 2.0 has been released and now includes the Angular Language Service, and more features like tabbed editing

Documentation Updates
We’re always working hard to improve our guides and reference materials. Continue reading


AngularJS Events Tutorial

This angular directive will not override the element’s original event i.e. both operations will be executed. This angular directive will not override the element’s original event i.e. both operations will be executed. This angular directive will not override the element’s original event i.e. both operations will be executed. The angular directive evaluates the angular expression when a value of an element changes i.e. this event is triggered at every change in a value and will not wait until all the changes are made or when the input text-field loses the focus. This angular directive will not override the element’s original event i.e. both operations will be executed. Continue reading


AngularJS Dependency Injection Example

In angular, a value is a simple javascript object that passes the value to the angular controller, factory or the service method during the run and the configuration phase. This function has the following prototype form:

In angular, a provider is a flexible form of the factory function which is internally used by the angular framework to create the service, factory etc. during the configuration phase. This function has the following prototype form:

In a real world, developer’s first contact with the Dependency Injection principle is with the value in the controller. It will have the following code:

Let’s start building an application to understand the basic building blocks of the dependency injection principle in the angular library. In this section, developers learned about the concept and several benefits of using the dependency injection in the angular library. Continue reading


Real-Time Search With AngularJS Custom Filter

In this tutorial, we will see how to create Real-Time Search With AngularJS Custom Filter. We will be creating a custom filter to achieve this and not the default search provided by Angular. Filters are used to change modify the data and can be clubbed in expression or directives using pipe character. To create a live search we have to create a JSON data from which the angular will filter the result. Now, will design our page, in which it will contain an input text field and our list of JSON data.

Clean Up Your Angular Form Template – Netanel Basal

Clean Up Your Angular Form Template
In my previous article, we talked about how to show form errors on submit. When your form start to grow, you can end up with something like this:
If you are coding all your forms like that, you are probably Psychopath 😜 (just kidding)
The template is verbose; it’s hard to understand what’s going on and you are not DRY. Next, we can ask Angular to give us the ngForm instance in our component via dependency injection with the Host decorator. ( we are using also the Optional decorator to protect our code )
That’s the equivalent of doing this in our template:
form #myform="ngForm"/formIf you are still confused from where this NgForm is coming, In a nutshell, it’s just a built-in directive with a selector that points to almost any form tag. @Directive({
selector: class NgForm extends ControlContainer implements Form {}Ok, now we have the form instance let’s get the errors. Continue reading


Angular Material Datatable With Angular 6 – Part Two

In this second part of the article on Angular Material Datatable, we are going to learn how to implement searching, filtering, and one combined example in which we will implement all of the functionality using Angular Material Datatable. In the first part of the series, we have learned different functionalities of Angular Material Datatable. Combined example of Angular Material Datatable with all the functionalities To implement this example, we can create a new separate component by executing the below ng command. This HTML file contains all of the code which is used to implement the datatable with all the functionalities. We are done with our example, now let's quickly run our example and see the complete and full fledged working Angular Material Datatable with different functionalities. Continue reading


Routing In AngularJS Using UI-Router

Angular UI-Router is a client-side Single Page Application routing framework for AngularJS. We will be specifying every component in a different folder so starting with folder structure. let’s first implement the header view from there we will be linking our components using UI-router, as you can see our directory structure we have separated header and footer in the shared folder and other pages in components. Similarly create your own custom components i.e header, footer, home page, etc as the directory structure shown. you can see we have created our demo angularApp by implementing the module i.e ui-router imported from the CDN link and the other one app.routes, in that module we will create our custom routes.

Understanding Angular 6 Animations – DZone Web Dev

Animation is a transition from one state of the element to another state. Angular provides us the following three timing properties:

This property represents the time our animation takes to complete from start (initial state) to finish (final state). We can define the duration of the animation in the following three ways:

This property represent the time duration between the animation trigger and the beginning of the actual transition. The state and transitions for our animation need to be defined in the trigger implementation. Each transition function has a defined to show the change of state of an element and the corresponding array of animation steps to show how the transition will take place. Continue reading


AngularJS with Spring MVC Example

Hello readers, in this tutorial we will create a simple application that uses the spring and angular framework. Therefore, let us create a simple application using the Spring and Angular libraries. Here is a step-by-step guide for implementing Spring MVC architecture in the angular web applications. In this tutorial, developers learned how to create a simple application using the Spring and Angular libraries. This was an example of creating a simple application using the Spring MVC and Angular framework. Continue reading


The Angular Library Series – Creating a Library with the Angular CLI

Now that we have a high level view of what our Angular workspace will look like, let’s set some specific goals for this tutorial:
Goals
Use the Angular CLI to create a workspace with the same name as our intended Angular library: example-ng6-lib
We will have a test application for our example-ng6-lib library named:
example-ng6-lib-app
In our example-ng6-lib workspace generate an Angular library named:
example-ng6-lib
Our Angular library will have the prefix of enl to remind us of Example Ng6 Library. ALWAYS: Use a prefix when generating a library.One of the great things about the Angular CLI generate command is that it always tells you what files it affects:
$ ng generate library example-ng6-lib –prefix=enlCREATE (968 bytes)
CREATE (191 bytes)
CREATE (164 bytes)
CREATE (175 bytes)
CREATE (700 bytes)
CREATE (191 bytes)
CREATE (769 bytes)
CREATE (246 bytes)
CREATE (317 bytes)
CREATE (261 bytes)
CREATE (679 bytes)
CREATE (281 bytes)
CREATE (418 bytes)
CREATE (142 bytes)
UPDATE angular.json (4818 bytes)
UPDATE package.json (1724 bytes)
UPDATE tsconfig.json (471 bytes)Here is a quick summary of what the generate library command does:
Adds a new example-ng6-lib project for our library in angular.json
Adds dependencies for ng-packagr to our package.json
Adds a reference to the example-ng6-lib build path in tsconfig.json
Creates sources for our library in this is Angular in Depth let’s actually take an in depth look at each of these items. So, it adds it to our devDependencies in our workspace package.json:
"ng-packagr": "^3.0.0-rc.2",build path in tsconfig.json
When testing example-ng6-lib we want to be able to import it like a library and not just another set of files that are part of our application. You want to import the module in the application using the library by name like this:
import { ExampleNg6LibModule } from 'example-ng6-lib';This works because when importing a library by name, the Angular CLI looks first in the tsconfig.json paths and then in node_modules. ALWAYS: In your test application import using your library by name and NOT the inidual files.Your app.module.ts file should look like this:
Displaying the example-ng6-lib Component
To keep things simple let’s just add the default generated component from our library to our AppComponent template in: src\app\app.component.html
You can just replace the bottom half of the AppComponent template src\app\app.component.html should look like this:
Running Our Application
As always we can run our application using:
ng serveAnd now when we point our browser at:
http://localhost:4200/
we should see the test for our component from our library. Continue reading


Why Angular 2/4 Is Too Little, Too Late – Chris Cordle – Medium

Thanks to webpack, NPM on the front-end, and a mature ecosystem of tooling and libraries, it is quite easy to maintain a large, flexible, well-engineered SPA with React, Vue, or other lightweight JS libraries, even at enterprise companies with large teams. A lot of people will tell you that this is a Coke vs. Pepsi debate, framework vs. library, tradeoffs, pros/cons, etc, etc. but in 2017, it’s easy to see that Angular 2/4 will never reach the top-tier status of its popular AngularJS predecessor. In 2013, Angular and every other JS framework was pitching two-way data binding as a feature. Microsoft would later release React Native libraries for building Windows applications: React Native powers Instagram, Facebook, Wal-Mart, Baidu, Skype, Discord, and a slew of other professional grade applications. NPM, ES2015, Babel, Webpack
While Facebook was rapidly innovating on the implications of React, a few key developments were occurring in parallel in front-end JavaScript. Continue reading


Using Nrwl/Nx to Upgrade You AngularJS Applications to Angular

We can set it up by running ng generate downgrade-module tusk-desk, where tusk-desk is the name of the AngularJS module. package.json
Similar to the previous schematic, downgrade-module updated package.json to add the @angular/upgrade and AngularJS to upgrade-module, this schematic rewrote AppModule not to bootstrap AppComponent. First, we are importing the AngularJS and the existing tusk-desk application. Second, we are converting AppModule into an AngularJS module by using downgradeModule. This means that we can upgrade an AngularJS component and use it inside AppComponent. Continue reading
