A single field tells us in plain language what the status of the object is by using enums instead of booleans. Another upside is the extensibility and future-proofing that this technique gives us. If we go back to our previous example of adding a “pause” mechanic,... See more

Whenever you write a log, it’s important you choose the correct log level.

I personally mostly use ERROR, WARNING, INFO, or DEBUG (yes there are a few more).

Log levels TLDR

• ERROR: Parts of the flow failed, we want to send alerts to our on-call for this failures.


• WARNING: Doesn’t necessarily point to a failure, but an unexpected behavior that should

Hopefully, at this point, you see where I’m going with this. What I’ve concluded, based on experience, is that positioning your project as an alternative implementation of something is a losing proposition. It doesn’t matter how smart you are. It doesn’t matter how hard you work. The problem is, when you build an alternative implementation, you’ve... See more

When a test fails, you should be able to begin investigation with nothing more than the test’s name and its failure messages —no need to add more information and rerun the test.

Effective use of unit test frameworks and assertion libraries (JUnit, Truth, pytest, GoogleTest, etc.) serves two important purposes. Firstly, the more precisely we express... See more

Loose Coupling and High Cohesion: How To Avoid Tight Coupling and Low Cohesion?

Cohesion is a measure of the number of relationships that parts of a component have with each other.

High cohesion means that : All of the parts that are needed to deliver the component's functionality are included in the component.

Coupling is a measure of the number of... See more

The book Clean Code introduces three laws of TDD [1]:

1. Write a failing unit test first before you start writing production code.


2. Write not more of a unit test than is sufficient to fail.


3. Write not more production code than is sufficient to pass the currently failing test.

So, the tests are written before the production code. This leads to the developer... See more

Using feature flags

It's always a good idea to put new features behind a feature flag.

This contributes to a rollout strategy that can surface user feedback in a much more contained and safe environment.

When thinking about how to rollout a new feature to users, first think about your peers. Many of the Resend team members also use Resend on their... See more
