Creating microservices can often feel complex, but the right tools make the process much more manageable. One such tool is MicrostarterCLI, a command-line interface designed to streamline the creation of Micronaut microservices. If you’re developing in a JVM-based environment, Micronaut is an ideal framework that supports high-performance applications. This article explores how you can simplify microservice development using MicrostarterCLI, offering a step-by-step guide to get you started and a closer look at its key features.
Why Micronaut for Microservices?
Before diving into MicrostarterCLI, it’s essential to understand why Micronaut is an excellent choice for building microservices. Unlike traditional frameworks, Micronaut is lightweight, fast, and optimized explicitly for microservices and serverless applications. It leverages ahead-of-time (AOT) compilation to reduce memory consumption and startup time, making it perfect for cloud-based architectures. With its powerful dependency injection system and seamless integration with GraalVM, Micronaut is designed to solve many of the pain points developers face when working with microservices.
What is MicrostarterCLI?
MicrostarterCLI is a command-line interface designed to accelerate the development of Micronaut microservices. Automating much of the initial setup allows you to focus more on building your application’s core business logic. Instead of spending time configuring project dependencies and boilerplate code, MicrostarterCLI handles it for you in just a few commands.
Getting Started with MicrostarterCLI
Before you can start building microservices with MicrostarterCLI, install it. Below are the installation options for different operating systems:
- Using Homebrew (macOS):
- Using Scoop (Windows):
- Manual Installation: Download the latest release from the GitHub repository and follow the setup instructions provided.
Creating a New Micronaut Microservice
After installation, building a Micronaut microservice is incredibly simple. Just run the following command to create a new project:
This command generates the entire project structure, setting up the necessary files and configurations. You can customize the project name and choose templates that best suit your needs, allowing for a flexible development process. For instance, selecting specific templates lets you initialize your project with predefined configurations suited for microservice architecture.
Key Features of MicrostarterCLI
MicrostarterCLI offers several essential features that help optimize the process of building microservices:
- Project Initialization: MicrostarterCLI automatically generates the required project structure, saving you time and effort during the initial stages of development.
- Template Selection: You can start your project by choosing from multiple templates, ensuring you begin with the correct configuration for your specific needs.
- Dependency Management: MicrostarterCLI supports both Maven and Gradle for managing dependencies, simplifying the addition of new libraries and packages to your project.
- Code Generation: Boilerplate code for essential components, such as controllers, services, and repositories, is automatically generated. This means you spend less time writing repetitive code and more time focusing on business logic.
- Customization: The tool allows developers to customize the generated project completely, tailoring it to their requirements.
Building and Running the Microservice
Once the project is initialized, you can begin adding your business logic. Micronaut’s annotations and APIs simplify the process of defining the behavior of your microservice. For instance, you can create a simple controller as follows:
This simple controller listens on the /hello endpoint and returns a greeting message.
After adding your business logic, you can run the microservice using the following command:
This command launches your service, and you can test its functionality by sending requests to the appropriate endpoints.

Benefits of Using MicrostarterCLI
Using MicrostarterCLI to build Micronaut microservices offers several advantages:
- Speed: MicrostarterCLI accelerates development by generating the entire project structure and necessary boilerplate code. This lets you focus on creating features rather than setting up the environment.
- Best Practices: The tool ensures that your project follows best practices by structuring it properly and configuring essential dependencies.
- Simplified Dependency Management: Managing dependencies can often be cumbersome, especially when integrating third-party libraries. MicrostarterCLI handles this for you, ensuring all required dependencies are correctly managed using either Maven or Gradle.
- Flexibility: While MicrostarterCLI handles the initial setup, you can still fully customize your project. You can modify dependencies, change templates, and even write custom code.
