19:30 Cypress - The Art of simple E2E Testing

End-to-End (E2E) testing is a crucial aspect of software development. Setting up effective and reliable E2E-tests, however, can be time-consuming and frustrating. Cypress takes the approach of focusing on developer experience. It aims to make writing test simpler and more stable. The goal is to write more meaningful tests and to make it an enjoyable process.
In this presentation, we provide a short overview of the main types of software testing, we examin best practices and the pros and cons of the framework. Join us as we delve into the world of Cypress and explore how it can enhance your testing experience.

20:05 Navigating Data Horizons - A Python Expedition into Geospatial Analysis

Geospatial analysis refers to techniques and processes used to interpret and derive insights from spatial data. Using Python libraries such as geopandas, folium, and OSMnx, we will explore location-based data and spatial relationships from freely available spatial data. You will learn how to query OpenStreetMap data, visualize administrative boundaries, and explore street networks.

Speaker: As a software engineer at adesso SE, Sabine Heiland specializes on data science and data analysis. Her main focus lies on gaining insights from geospatial data in GIS systems, as well as extracting information from unstructured textual data

✨ Attribute Injection - Angular 17.3.0-next.1

Release 17.3.0-next.1 führt eine neue HostAttributeToken-Klasse ein, mit der ihr Attribute ähnlich wie @Attribute implementieren könnt.

Es kann wie folgt verwendet werden:

import {HostAttributeToken, inject} from '@angular/core';

class MyDir {
  someAttr = inject(new HostAttributeToken('some-attr'));
}

Die neue API verhält sich ähnlich wie der @Attribute-Dekorator, mit einem großen Unterschied: Sie löst einen DI-Fehler aus, wenn das Attribut nicht vorhanden ist, anstatt null zurückzugeben.

In Angular 17.2 🔥, one of the interesting feature is Automatic placeholders with NgOptimizedImage.

If you’re using the NgOptimizedImage directive for your images, you can now quickly add a blurry placeholder while an image loads. Just add the placeholder attribute to your image, and the image directive will automatically request a small version of the image, blur it, and display that until the full image is ready.

UX will be enhanced with this feature.

Exploring TypeScript: Mapped Types 🗺

Mapped Types in TypeScript allow you to transform and manipulate existing types and create new types dynamically. They enable you to iterate over the properties of a type and generate new types based on those properties.

Why are They Cool?

Mapped Types provide an elegant solution for scenarios where you need to transform or extend existing types in a systematic and type-safe manner. They offer advanced techniques for type manipulation and abstraction, elevating TypeScript to a whole new level.

Real-world Application

Imagine you're building a complex application with various data structures, each requiring specific transformations or enhancements. Mapped Types come to the rescue, enabling you to define precise mappings and generate tailored types effortlessly.

Key Benefits

1️⃣ Dynamic Type Generation: Mapped Types enable dynamic generation of new types based on existing types, providing flexibility and expressiveness.
2️⃣ Type Safety: They ensure type safety by preserving the structure and constraints of the original types during transformation, preventing unintended errors.
3️⃣ Code Maintainability: Mapped Types promote code maintainability by abstracting complex type transformations into reusable constructs, enhancing code readability and scalability.
