AngularJS 1.x was and still is the most popular JavaScript framework, and more than one million (!) developers are using it today. I guess someone at Google decided to capitalize on the popular brand and this is how the concept of the new version of AngularJS came about. Overall I think it was a smart marketing Equity Management Software for Service Providers Diligent Equity decision, which was supported by the fact that the creator of AngularJS and Angular 2 was the same rock star software engineer Misco Hevery. But rock star software engineers do create different products. In the second task called copy I am copying my application files from app folder to folder.

It’s worth noting that the updates to the CLI to make this possible also include backwards compatibility for older Gulp-driven projects. So even as these new features become the default, Gulp will still be supported for older projects. And if you still want to use Gulp in new projects, no problem! Any task runner, or even straight node calls, can execute these scripts. Also we need to mention a small nuance on the product naming.

Version 2

They will be working on Ivy to improve output bundle sizes and development speeds. Michi Kono, Senior Director of took the stage to show off what they’ve done with Angular Universal, which “allows the Angular engine to run server-side”. is a heavily trafficked site with extreme performance, SEO, and regulatory requirements. Their previous work with Angular 1 resulted in the need to build a complicated custom rendering system.

While writing the book we created multiple sample apps and had to change all of them each time when the new alpha release of Angular 2 was made available. This was expected and we survived a couple of dozen of such releases. Early this year the framework went to the beta phase, and in May of 2016 the Release Candidate 1 was announced. This release brings Ionic 2 very close to its final form. Between each alpha and beta version, we’re sure you’ve noticed significant changes to the API…but no more! The API for this release candidate is the same we hope to ship for our final (which isn’t far behind).

GraphQL can be a great choice for client to server communication, but it requires investment to maximize its potential. Netflix operates a very large, Federated GraphQL platform. Like any distributed system, this has some benefits, but also creates additional challenges. In this episode, Tejas Shikhare explains the pros and cons of scaling GraphQL adoption. Now we need to adjust our index.html and add all needed Angular 2 scripts and system.js module loader code.

All of the packages are now distributed under the @angular npm scope. This changes how Angular is installed via npm and how you import the code. A new router in Angular 2 supports “lazy loading,” added Green. “When users come to the first view of your application, we’ll automatically only load the JavaScript modules that are required for that view.” We’d also like to point out that Ionic is not tied to any one bundler or our @ionic/app-scripts package.

I am telling it I have one package, called app, which is assumed to be in app folder under the root. I am telling it to use js extension by default. I am telling it to use register style module loader. Now we want npm to download Angular to this project as a dependency. We want Angular with its dependencies to be downloaded to our project directory node-modules.

To illustrate these concepts we use, as an example, the Hilbert’s Hotel mathematical problem. Why don’t we instead focus on seeing what we can do to help out and make NG2 better. Whether that’s adding documentation or opening issues, or even submitting code. But thats fine, you can use something UI-Router if it matters that much to you.


I am going to assume you setup Visual Studio 2015 and installed ASP.NET 5 RC. The code of your app can be compiled either dynamically or statically. If it’s dynamically compiled in the browser, this is called just-in-time compilation . If the code is precompiled, it’s called ahead-of-time compilation. I’m talking about the Angular compiler-cli , and not just transpiling from TypeScript to JavaScript here. A half of the size of a small app is the Angular compiler itself, and just by using the AoT your app becomes slimmer because the compiler won’t be downloaded to the browser.

  • In this file we are importing our own class, Main from Main module.
  • Angular 15 was released on 16 November 2022.
  • I’m talking about the Angular compiler-cli , and not just transpiling from TypeScript to JavaScript here.
  • A half of the size of a small app is the Angular compiler itself, and just by using the AoT your app becomes slimmer because the compiler won’t be downloaded to the browser.
  • Previously, the paint happened at the end, so users not only couldn’t interact with the site, they had to wait before they could see the content.

If you are following the Angular space, you will have noticed that the Angular team is dropping versioning when referring to the Angular JS framework. You can still expect documentation and learning resources to refer to appropriate version of Angular. Lastly, if you are looking into development in Angular 1.x and Kendo UI, you should use Kendo UI for jQuery as it has wrappers which will suit your needs. Because after you take so much effort to convince the management and the team to start using Angular 2, preach about Angular 2. And the changes are so significant that you need to put in effort to update the code instead of building features. Some new features include typed forms, standalone components, and new primitives in the Angular CDK .


Normally npm init asks several questions while creating the file, but the -y flag makes it accept the default values for all options. The following example shows the log of this command running in the empty angular-seed directory. To start a new project managed by npm, create a new directory (e.g. angular-seed) and open it in the command window. The first release candidate of my angular 2 component library has been released . This library provides components and directives that can be used in angular 2.

We took our time and looked at all the available build tools and fell in love with Rollup. There are many build tools out there, and they all do a great job, but for us, Rollup provides some nice technical features, like much more optimized code that tends to have fewer closures. This enables code to be executed much faster in the browser.

We also want local versions of SystemJS, live-server, the TypeScript compiler, and any other third-party libraries that our app needs. With @NgModule being introduced, we decided to rename the top source directory to src (mind-blowing, we know!). All of the files related to the root app component and @NgModule get stored in an app folder, while pages and providers sit in src/. We’ve also added an assets directory to house things like images, manifest.json, and a service worker file. We’ve also made some changes to the default app you get from ionic start, which will make a lot of sense when you see them.

Only the bootable module needs BrowserModule. Each of the feature modules can be loaded either eagerly when the app starts, or lazily, e.g. when the user clicks on the “shipping” link. Angular 2 is about to be officially released (most likely it’ll happen at the AngularConnect conference on September 25, 2016). The current version of of Angular is Release Candidate 6 and I’ll describe how to create your first project with this release.

Does it really have to be that time consuming to upgrade from one RC to another? There is even a guide titled “RC4 to RC5 migration“. It has an optimistic subtitle “Migrate your RC4 app to RC5 in minutes.” Yeah, right!

Standalone APIs graduated from developer preview and are now part of the stable API surface. Angular does not have a concept of “scope” or controllers; instead, it uses a hierarchy of components as its primary architectural characteristic. QCon London brings together the world’s most innovative senior software engineers across multiple domains to share their real-world implementation of emerging trends and practices.

Since our module contains only one class, we need to list it in the declarations property, and list it as the bootstrap class. The list does not stop here; Earlier in the quarter we released support for some of the framework fundamentals—AoT and Universal Rendering. We listened to your feedback in GitHub and addressed more than a hundred issues.

You can find the source code of our angular-seed project (the RC.6 version) here. Most of the generated configuration is needed either for publishing the project into the npm registry or while installing the package as a dependency for another project. Using the AoT compilation will decrease the application footprint even more because the app sent to the browser won’t include the internal Angular compiler.

It’s so excited reading the official announcement on Angular. But also to take a back seat, see what’s going to happen, and not making the team frustrated. Actually, until RC4, I didn’t do any upgrade on my existing projects nor my articles on The Angular ecosystem has grown, yet become more coherent. Beyond just plain-old Angular, there are now a number of subsites that relate to specific spin-off projects. InfoQ will provide more coverage of some of these over the coming week.
