API Gateways are a nice place, if not THE right place for handling request validation and responding with human readable and uniform error responses. Implementing the validation manually for every API would be a mess... but wait, what if this could be done automatically by simply feeding our OpenAPI Specification to a gateway like Express Gateway.

Express Gateway is an API Gateway built on Express.js. It has the advantage of being simple and minimalist but also flexible and highly extensible thanks to JavaScript plugins. This recipe will show you how to quickly setup Express Gateway as an API Gateway.

OpenAPI Specification (formerly known as Swagger) is a format that allows you to describe and document your HTTP API or ReSTful API from the interface to the authentication schemes and the permissions required for each route. A wide range of tools can use the OpenAPI Specification format to help you manage the lifecyle of your APIs from designing them to securing them while improving API consumers Developer eXperience.

Stale or long-lived branches, conflicts & huge code reviews can cause technical and human issues in your team. In this talk, Younes demonstrates some alternative and sometimes extreme approaches promoting single-branch development with techniques like Limbo, Timeboxed TDD and Test && Commit || Revert.

Angular modules can bring some complexity to your app. Choosing the right modules architecture is tricky... but wait, do we really need modules?

An introduction to the Angular CLI by the Angular team.

Controlling the behavior of a whole application or page can quickly get tricky if we don't split it into smaller chunks. In Angular, these chunks are called components. Every component is reusable and allows us to control the display and behavior of some part of the application or page. This official documentation gives a nice introduction on how components work.

Angular Modules, or NgModules are the main modularity system in Angular. They are fundamental for architecturing & structuring our apps and libraries in a performant, readable and scalable way.

Unsurprisingly, the official TypeScript documentation contains one of the best introductions to TypeScript.

Angular apps, like any other kind of apps, can get big. One way of optimizing our apps is to avoid loading modules that we don't need immediately. This is called lazy-loading. You can learn more about it in the official documentation.
