How to Install Gonic on OpenBSD

Gonic is a simple and efficient framework for building HTTP web applications in Go. This tutorial will guide you through the process of installing Gonic on OpenBSD.

Prerequisites

• OpenBSD operating system installed
• Internet connection

Step 1: Install Go

Before we can install Gonic, we need to install Go. OpenBSD has the Go programming language pre-installed, but we need to update it to the latest version.

1. Open the terminal and run the following command: sudo pkg_add go
2. Once the installation is complete, verify the installation by typing go version in the terminal. It should display the latest Go version.

Step 2: Install Git

In order to download Gonic, we need to install Git.

1. Run the following command in the terminal: sudo pkg_add git

Step 3: Download and Install Gonic

1. Open the terminal and navigate to the directory where you want to download Gonic.
2. Clone the Gonic repository using Git by typing the following command in the terminal: git clone https://github.com/sentriz/gonic
3. Navigate to the Gonic directory using cd gonic.
4. Build and install Gonic by typing the following command: go install

This will install Gonic and its dependencies to your Go workspace.

Step 4: Verify the Installation

To verify the installation, we will create a simple Hello World application using Gonic.

1. Create a new directory for the project by running mkdir myapp in the terminal, where "myapp" can be any name of your choice.
2. Navigate to the project directory using cd myapp.
3. Create a new file named main.go by running touch main.go.
4. Open main.go in your favorite editor and paste the following code:

package main

import (
  "github.com/sentriz/gonic"
)

func main() {
  app := gonic.Default()

  app.GET("/", func(ctx *gonic.Context) {
    ctx.String("Hello World!")
  })

  app.Run(":8080")
}

5. Save the file.
6. In the terminal, navigate to the project directory and type the following command to run the application: go run main.go.
7. Open a web browser and go to http://localhost:8080. You should see "Hello World!" displayed in your browser.

Congratulations! You have successfully installed Gonic on OpenBSD and created your first Gonic application.

Conclusion

In this tutorial, we walked through the process of installing Gonic on OpenBSD and creating a simple application that can respond to HTTP requests. Now that you have Gonic up and running, you can build more complex web applications using this powerful framework.

If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!

Alternatively, for the best virtual desktop, try Shells!
