Techniques involved in creating web applications have continuously evolved, since web applications evolved from simple static websites into complex multi-layered applications and API first systems.

Over time, monolithic systems became too complex to deal with: they grew into huge platforms and many teams are drawn to decompose a monolith to an ecosystem of microservices by isolating features into separate repositories.

Although separation of concerns with this approach allowed teams to deliver value in parallel and independently of each other, dependencies between the projects slowed them down a lot: even a small change required a PR in multiple repositories, figuring out…

Serverless architecture is without a doubt one of the hottest topics in cloud computing, allowing developers to build and run apps and services without thinking about the servers actually running the code as well as significantly reducing operational costs.

When we initiated a new project a few months ago, I decided to adopt this micro-services model — developing the back-end as a small series of services, each running independently and communicating through HTTP requests.

Then, I had to choose the server-side programming language to develop our backend.

Candidates were C#, TypeScript and Go

Except the last candidate, me and my…

The value of the software produced is directly affected by the quality of the codebase, and not every developer might

• be aware of the potential pitfalls of certain constructions in TypeScript,
• be introduced into certain conventions when using the Angular framework,
• know that not every developer is as capable in understanding an elegant (but abstract) solution as the original developer.

For that purpose, we need to use static code analysis tools such as TSLint and codelyzer to check readability, maintainability, and functionality errors.

Although complying with these tools may seem to appear as undesired overhead or may limit creativity, it…

Single page application (SPA) frameworks are probably getting the most attention in the JavaScript world in the past years. Handling most of the processing at the client, boiler-plating the content on every page, maintaining the “state”, and omitting the overhead latency on switching pages are just some of its net benefits.

SPA’s provide an awesome User Experience!

Hell yeah, but we’ve got a small problem: the application has to be indexed by search engines!

Many search engines and social networks such as Facebook and Twitter expect plain HTML to utilize the meta tags and relevant page contents. They cannot determine…

Every developer’s dream is to work on an environment capable of responding the commands, compiling and debugging in alignment with the developer’s speed of thought.

Although such computers and development tools do not exist on the market yet, there’re a few tricks that could boost Visual Studio performance and responsiveness, reduce the time spent for builds, and increase overall productivity and efficiency.

SSD Upgrade

First of all, upgrade to SSD drives if you’re still using those old-fashioned spinning-disk drives. …

Have an Angular application that uses the @angular/router to provide navigation across pages?

The following test sample could be scaled to your application to ensure routing is done correctly, from one component to another.

First of all, let’s import the dependencies we will need in this test:

import { BrowserDynamicTestingModule, platformBrowserDynamicTesting } from '@angular/platform-browser-dynamic/testing';
import { Component, NgModule } from '@angular/core';
import { TestBed } from '@angular/core/testing';
import { Routes } from '@angular/router';
import { RouterTestingModule } from '@angular/router/testing';

Then, let’s create a TestBootstrapComponent which contains the router-outlet — used to bootstrap the test app; and a TestComponent.

You won’t…
