My First CLI

Welcome to the “My First CLI” tutorial! In this guide, you will learn how to create a simple Command-Line Interface (CLI) application using Cobra.

Prerequisites

  • Basic knowledge of Go programming language.
  • Go installed on your system.

Steps

  1. Install Cobra

    First, initialize a new Go module for your project:

    mkdir my-cli
    cd my-cli
    go mod init my-cli

    Then install the Cobra library:

    go get -u github.com/spf13/cobra@latest
  2. Initialize Your Project

    Install the Cobra CLI generator:

    go install github.com/spf13/cobra-cli@latest

    Initialize your Cobra project:

    cobra-cli init
    Your Cobra application is ready at
    /path/to/my-cli
  3. Add Commands

    Add a new command to your CLI:

    cobra-cli add serve
    serve created at /path/to/my-cli
  4. Run Your CLI

    Build and test your CLI application:

    go build -o my-cli
    ./my-cli
    A longer description that spans multiple lines and likely contains
    examples and usage of using your command. For example:
    Cobra is a CLI library for Go that empowers applications.
    This application is a tool to generate the needed files
    to quickly create a Cobra application.

    Test the new serve command:

    ./my-cli serve
    serve called

Summary

By the end of this tutorial, you will have a working CLI application built with Cobra. Stay tuned for more advanced tutorials!
