Even though the word iframe causes bad feelings for most web devs, it turns out that using them for loading SPAs in a micro service based environment -- aka micro frontends -- is a good choice. For instance, they allow for a perfect isolation between clients and for a separate deployment. Because of the isolation they also allow using different SPA frameworks. Besides iframes, there are other approaches to use SPAs in micro service architectures -- of course, each of them has their own pros and cons. [Mehr]
In my last blog article, I've shown how to leverage Schematics, the Angular CLI's code generator, to scaffold custom components. This article goes one step further and shows how to register generated building blocks like Components, Directives, Pipes, or Services with an existing NgModule. For this I'll extend the example from the last article that generates a SideMenuComponent. [Mehr]
Since some versions, the Angular CLI uses a library called Schematics to scaffold building blocks like components or services. One of the best things about this is that Schematics allows to create own code generators too. Using this extension mechanism, we can modify the way the CLI generates code. But we can also provide custom collections with code generators and publish them as npm packages. A good example for this is Nrwl's Nx which allows to generated boilerplate code for Ngrx or upgrading an existing application from AngularJS 1.x to Angular.
These code generators are called Schematics and can not only create new files but also modify existing ones. For instance, the CLI uses the latter to register generated components with existing modules.
In this post, I'm showing how to create a collection with a custom Schematic from scratch and how to use it with an Angular project. The sources can be found here. [Mehr]

Over the last weeks, I've worked on version 2.1 of my OpenId Connect (OIDC) certified library angular-oauth2-oidc which allows for implementing Authentication in Angular using external Identity Providers that support OAuth 2 or OIDC.
Here are the added features ... [Mehr]
Although tuning an application's performance can be difficult, sometimes all we need to do is laying back and waiting for the next version of the used framework. This especially holds true for Angular as the Core Team is working constantly on improving things under the hoods. A good example for this is the conciser code the Angular Compiler emits beginning with Version 4 or the Angular Bundle Optimizer that transforms code to make it more treeshakable.
On more of this optimization techniques landed with 5.0.0-beta.4 about two weeks ago. It allows the compiler to remove unneeded (consecutive) white spaces from text nodes and to remove even whole text nodes that only contain white space characters. This leads to less code emitted by the AOT compiler and therefore to smaller bundle sizes as well as faster start up times.
In this post I'm describing how to use it, which performance gains I measured when applying to an example application as well as how this approach works under the covers. The example application I've used for this can be found in my GitHub repository. [Mehr]
Today, I've released a new version of the angular library angular-oauth2-oidc, which allows for implementing token-based Security using OAuth2/ OpenId Connect and JWTs with Angular.
It provides silent refresh, events and is able to directly validate the signature of received tokens. [Mehr]

When upgrading from AngularJS 1.x to Angular (2/4/5 etc.), we usually prepare our AngularJS 1.x code base first. This can involve leveraging new AngularJS 1.x techniques like components. Additionally, introducing TypeScript as well as module loaders like SystemJS or webpack are further tasks to prepare the existing code. The goal behind this is to draw near Angular in order to allow a better integration.
But in some situations preparing the existing code is too costly. For instance, think about situations where we just want to write new parts of the application with Angular without the need to modify much of the existing AngularJS 1.x code. When this holds true for your project, skipping the preparation phase could be a good idea.
This post shows step by step, how this approach can be accomplished. Like the official and well written upgrading tutorial which includes preparing the code base, it upgrades the popular AngularJS 1.x Phone Catalog Sample. [Mehr]

Currently, the Angular team is working hard on making Angular work together with Closure as well as with its build tool Bazel. There are some first examples available, e. g. the Example Alex Eagle from the Angular Team created.
This post uses the mentioned example to show how to use the closure compiler as well as the advantages it brings regarding bundle sizes. Furthermore, this post explains how to add own and existing packages to a Closure based project. [Mehr]

The Angular CLI provides AOT compilation out of the box. Under the hoods, it uses the package @ngtools/webpack which provides a loader for compiling TypeScript as well as a Plugin for AOT. One can easily use these mechanisms directly with webpack. [Mehr]
