RxJs’ combination static methods normally die when you don’t handle internal errors, in this article I show how to handle it correctly.

A practical scenario where you might encounter a certain form of unhealthy code. Note: This is an excerpt from my book Refactoring TypeScript: Keeping Your Code Healthy.

TypeScript 3.2 added a new –showConfig compiler flag to the tsc executable. It calculates the effective tsconfig.json file and prints it to the console.

Dependency Injection (DI) is one of the most important concepts that Angular incorporates.

Some of the calls made to APIs in our Angular apps don’t need to be made every time we need the data.

Here’s how you can enable TypeScript in your JavaScript project, and see errors and warnings from it in WebStorm.

Functional programming techniques in TypeScript, especially insightful for starters.

As a good developer, you always notify the end-user about the current status of an application by showing either loading indicator or error message.

In this tutorial, I am going to demonstrate how I was able to achieve a real-time search engine in Angular using several RxJS libraries available.

FontAwesome is the internet’s most popular icon toolkit which has been redesigned and built from scratch.

Learn how to use GraphQL for API development when working with an Angular 8 app. We’ll also use the Apollo client to make GraphQL work.

We explain how you can divide form controls by form groups in Angular 8, providing a platform to easily access the template element as groups.

Prima replaces traditional ORMs. This repo is used as a central point to collect information and issues around Prisma 2 while it’s in Preview. It also contains the documentation and the code of the Prisma 2 CLI.

The next generation i18n library for Angular just got better.

You’ll be able to appropriately narrow down values from iterators when dealing with them directly. Moreover, the array spread emits more accurate code. The Playground gets some new toys to play with, with added functionality.

A greenfield project gave us an opportunity to define testing standards from scratch. After much debate, we decided to optimize for easy rewrites.

While JIT (just-in-time) compilers have been very successful in making JavaScript performant, we needed a better solution to deal with these new workloads.

Modern front-end frameworks and libraries make it easy to create reusable UI components. But, in many projects over the years I have found that making reusable components is often not enough. We need a scalable front-end architecture.
