2018-02-21

In this article I will describe how to add a Http Authentication Bearer token to each request done from Angular via HttpClient by implementing a Angular 5 HttpInterceptor. This way the bearer token has not be added to each request separately while doing Ajax request e.g. to a REST api. This is for example useful, if you have some api that is protected by OAuth and you have to sent a JWT token in order to get access.

Aurelia – validation of dependent inputs

2017-11-20

Form validation in Aurelia is actually pretty nice. You can configure the validation rules in a chainable api and add multiple rules to single fields. However there is a problem if you want to trigger the validation of an input when another input is filled. A good example are two inputs (a start value and an end value). Of course you want to validate that the start-value is less than the end-value. But if you add the rule to both fields only the edited field will show (and reset) the error message. Ok… This explaination might be a bit confusing… Let’s…

Changing the Timezone in Debian 9 (Stretch)

2017-11-18

Since the release of the newest Debian version 9 (Codename “Stretch”) in June 2017, most system administrators using this distribution will upgrade their systems eventually.

Angular2 Internationalization (i18n)

2016-11-01

When you build frontend interfaces for the web, you often have to provide support for different languages, locales and timezones (generally called internationalization or short i18n in computer science). With Angular2 you can use the module “ng2-translate” to provide browser language detection and to resolve internationalized text fragments. In this article I will show how to use language files for Angular2. Include Angular2 translation module The ng2-translate  module can be simply added to your project via npm by calling:

Next you have to add the module to your Angular2 application module, by including  TranslateModule  from ng2-translate :
