Why I Started Using .http Files

I recently discovered how convenient it is to use .http files for API testing directly within an Integrated Development Environment (IDE). This method has proven to be an efficient and streamlined way to manage API interactions. Here’s a closer look at how this approach is enhancing my workflow:

What Are .http Files?

A .http file is a simple text file that defines HTTP requests. When equipped with the right extensions, .http files can be executed directly from some IDEs, such as JetBrains IntelliJ IDEA, WebStorm, or Visual Studio Code. This setup allows me to write and send HTTP requests without needing a dedicated API client tool like Postman or using curl commands in the terminal.

Key Benefits of Using .http Files

Convenience: I can stay focused in a single environment by enabling API testing within the IDE, minimizing context switching, and boosting productivity.

Version Control Integration: Storing .http files in the project’s version control system allows my team and I to share, review, and update our API tests just like any other source code. This integration ensures everyone is aligned and can track changes over time.

Collaboration: Sharing .http files among team members simplifies the process of demonstrating how to interact with APIs or replicate issues, fostering better understanding and quicker problem resolution.

Environment Integration: Defining environment variables in the IDE makes it easy to switch between development, staging, and production environments without modifying the requests themselves.

Immediate Feedback: Executing requests and seeing the responses immediately in the same window is invaluable for debugging and developing complex APIs.

How I Use .http Files

A .http file typically contains details such as the HTTP method, URL, headers, and the body of the request. I can organize multiple requests in a single file, separated by “###”. Here’s a simple example of how these files look:

http

### Get user list
GET http://api.example.com/users
Authorization: Bearer {token}

### Create a new user
POST http://api.example.com/users
Content-Type: application/json
Authorization: Bearer {token}

{
  "name": "John Doe",
  "email": "john.doe@example.com"
}

In my JetBrains IDE, I can simply click the green play button next to each request to execute it directly, displaying the response inline. This allows me to make adjustments and see the results instantly.

Practical Use Cases for Me

Development: I quickly test API endpoints while developing them, ensuring everything works as expected in real time.

Documentation: I use .http files in API documentation to provide real, executable examples for the development team.

Debugging: These files help me reproduce and troubleshoot API issues efficiently by re-running saved requests.

What tools do you use for API testing during development?

Why Microsoft Azure Well-Architected Framework Can Improve Architecture

Small and medium-sized businesses often face a common challenge: the absence of experienced cloud engineers. Due to limited resources, teams typically choose the quickest path—getting things done in the easiest, fastest way. Unfortunately, this approach often leads to solutions that aren't secure, cost too much, and become nearly impossible to extend or manage effectively. Recognizing this critical challenge, Microsoft Azure has developed the Well-Architected Framework. This comprehensive set of guidelines and best practices helps businesses assess their existing solutions and guides them toward building robust, secure, cost-effective, and manageable cloud infrastructures from the start. The Azure Well-Architected Framework is structured around five essential pillars: Cost Optimization : Ensuring that cloud resources are used efficiently and effectively, reducing unnecessary expenses. Operational Excellence : Focusing on the ability to run and monitor systems effectively, ensuring ...

"Dushnylo" Series: Monolith First approach.

I keep hearing, “You MUST start with a monolith.” Every new project? Always? When I hear that, two thoughts immediately come to mind:      1️⃣ “It depends.” You can’t just blindly say every project must start as a monolith.      2️⃣ My inner Dushnylo whispers: “Time to make a post about this.” So, here’s my take: I disagree. Not only do I disagree, but I believe the most critical and dangerous part of system design is analyzing and understanding business needs before making architectural decisions. Why? Simple. Imagine you’re building a streaming platform that processes massive amounts of data, handles notifications, and integrates with third-party services. Does this sound like something you’d build as a pure monolith? Of course not. But I do agree on one thing—you have to start somewhere. That starting point could be a simple core application —yes, it might look like a monolith at first. But you’re not designing the entire system as a monolith. ...

"Dushnylo" Series: The Trouble with GET: Real-World REST API Challenges

Have you ever seen a fully implemented, truly and absolutely by-the-books REST API? With all the correct HTTP methods, status codes, and the perfect design? No? Me neither. And you might ask — why not? After all, it's supposed to be easy , right? Well, yes — technically, it is easy. But in real life, you always run into edge cases. Let’s take a simple example. According to REST principles, if you want to retrieve data, you should use the GET method. Simple and elegant, and documented everywhere. But then the question arises: how do you pass parameters in a GET request? Answer: via URL path or query parameters. But as you already know, there’s a limit to how much you can fit into a URL — usually around 2048 characters . That’s fine for small, basic queries. But what about advanced searches ? You want to pass dozens of filters , custom ordering , maybe even a list of IDs to fetch. Sometimes it’s a list of GUIDs — and not just one or two, but hundreds . In these cases, G...
