Pitfalls in Testing NestJS Modules using HttpService

In this blog post, we will delve into the challenges developers face when testing NestJS modules utilizing HttpService from @nestjs/axios and explore the crucial role played by the RxJS TestScheduler in overcoming these hurdles. Additionally, we will unravel the intricacies of injecting HttpService into the test module, providing you with a comprehensive guide to fortify your testing strategies and ensure the robustness of your NestJS applications.

Authenticating Access to Private Content Hosted with AWS CloudFront

Setting up a static website, uploading it into an S3 bucket that serves as the origin of a CloudFront distribution is a simple and cheap solution. But what if you want to control access to the content? HTTP basic authentication no longer seems to work and is clumsy and ugly anyways. But signed cookies give you a better solution at hand and it is easy to implement with serverless computing.

Dynamic Angular Configuration

Angular apps traditionally rely on static configuration through environment files, necessitating separate builds for each environment ‐ a cumbersome process in practical scenarios. In this blog post, we describe an alternative, where configuration is loaded dynamically at runtime, streamlining development and enhancing flexibility. As an additional benefit, we will validate the configuration against a schema and add type-safety to it.

Creating Electronic Invoices with Free and Open Source Software

Starting 1 January 2025, electronic invoicing will become mandatory for all B2B transactions in Germany. Several other countries in the European Economic Area have already adopted similar requirements, or will soon follow suit. As a result, many businesses in Germany are racing to implement electronic invoicing solutions, though many face challenges along the way. Discover how you can simplify this process by generating electronic invoices in multiple formats — using only free and open-source software.

Hidden Quirks of JavaScript `for...in` Loops

The C-style three-expression for loop in JavaScript is often viewed as old school or awkward beginner style. Some developers automatically use a for...of, foreach, or for...in statement instead. But the latter has a subtle pitfall that can lead to unexpected behaviour.

How to Use Saved Passwords Everywhere

Some web sites and applications prevent users from using previously saved credentials. There a very few legitimate reasons to do so. In the vast majority of cases, such measures just patronize users, often those people that actually keep up the service with their financial support. But it is actually quite simple to bypass such paranoid settings.

Simple Single Sign-On Part 1 - (Open)LDAP

Individual user and password databases for every single service in a network are a nuisance for users and for admins, especially when users have a tendency of forgotting their password. Using LDAP for a centralized user management is less complicated than you might think. Even in a SOHO (Small Office/Home Office) environment LDAP is not overkill. Setting it up will pay out in little time.

Fruity Green Lentils Oriental Style

Lentils can be combined with pretty much everything. The combination with fruit has been on my list for a long time already. I wanted to go with pomegranate seeds that I could not dig up, however. So I tried it with the goji berries that have been lying around in my pantry for at least a year.
