The Power of Angular’s Dependency Injection and Directives |Michael Egger-Zikes:

The Angular framework’s built-in Dependency Injection (DI) mechanism has been integral since its inception, earning praise from the JavaScript ecosystem. While DI is commonly used for root-scoped services, its versatility extends beyond this. In this in-depth talk, developers will gain practical insights to unlock Angular’s DI system fully.From understanding provider hierarchies to utilizing Dependency Injection for customizing your application, attendees will enhance their personal Angular toolbox. Additionally, we’ll demystify the Injection tree, clarifying Injector node lifecycles and utilization. Directives are seamlessly integrated to imbue your Components with a generic, reusable approach by locally adding Providers.Join me as we explore Angular’s Dependency Injection system practically to streamline your development workflows for greater efficiency.

• Making My Node.js API Super Fast | Tamar Stern: 
• Node.js servers need to process a large number of requests concurrently as the scale grows. A Node.js micro service which receives an API request needs to do multiple actions, like parsing JWTs, use caching, work with the databases and more. But as systems need to parse millions of requests per second, the scale and performance becomes crucial.In this talk, Tamar will show strategies to improve your REST API performance – starting from new Node.js frameworks that can work faster, better parsing of request parts, efficient work with caching and DB and more strategies. The talk will include demos and benchmarks of code to see the improvements. At the end of this talk, developers will have practical knowledge on how to improve API performance.
