Introduction

In this tutorial, we will learn how to build a simple blogging platform using Go. By the end of this tutorial, you will be able to create a basic web server, handle HTTP requests, store and retrieve blog posts, and display them on a web page. We will cover the necessary concepts and step-by-step instructions to help you understand and build your own blogging platform.

Prerequisites

To follow along with this tutorial, you should have a basic understanding of Go programming language syntax and concepts. You should have Go installed on your system and have a code editor of your choice ready.

Setup

Before we get started, let’s set up the project structure and libraries required for our blogging platform.

  1. Create a new directory for your project:

     mkdir blogging-platform
 cd blogging-platform

  2. Initialize a new Go module:

     go mod init github.com/your-username/blogging-platform

  3. Install the necessary packages:

     go get github.com/gorilla/mux
 go get github.com/joho/godotenv
 go get github.com/mattn/go-sqlite3

Creating a Basic Web Server

Let’s start by creating a basic web server that listens on port 8000 and displays a welcome message when accessed.

  1. Create the main.go file:

     touch main.go

  2. Open main.go in your code editor and add the following code:

     package main
    
 import (
 	"fmt"
 	"log"
 	"net/http"
 )
    
 func homeHandler(w http.ResponseWriter, r *http.Request) {
 	fmt.Fprintf(w, "Welcome to the Blogging Platform!")
 }
    
 func main() {
 	http.HandleFunc("/", homeHandler)
    
 	log.Println("Server started on port 8000")
 	log.Fatal(http.ListenAndServe(":8000", nil))
 }

  3. Save and close the file. Run the server by executing the following command in your project directory:

     go run main.go

  4. Open your web browser and navigate to http://localhost:8000. You should see the welcome message displayed.

Implementing Blogging Functionality

Now let’s implement the blogging functionality. We will create routes for creating, reading, updating, and deleting blog posts.

  1. Create a new file called routes.go:

     touch routes.go

  2. Open routes.go and add the following code:

     package main
    
 import (
 	"database/sql"
 	"fmt"
 	"log"
 	"net/http"
    
 	"github.com/gorilla/mux"
 	_ "github.com/mattn/go-sqlite3"
 )
    
 func createPost(w http.ResponseWriter, r *http.Request) {
 	// Implementation for creating a new blog post
 }
    
 func readPost(w http.ResponseWriter, r *http.Request) {
 	// Implementation for reading a blog post
 }
    
 func updatePost(w http.ResponseWriter, r *http.Request) {
 	// Implementation for updating a blog post
 }
    
 func deletePost(w http.ResponseWriter, r *http.Request) {
 	// Implementation for deleting a blog post
 }
    
 func main() {
 	db, err := sql.Open("sqlite3", "./blog.db")
 	if err != nil {
 		log.Fatal(err)
 	}
 	defer db.Close()
    
 	router := mux.NewRouter()
 	router.HandleFunc("/post", createPost).Methods("POST")
 	router.HandleFunc("/post/{id}", readPost).Methods("GET")
 	router.HandleFunc("/post/{id}", updatePost).Methods("PUT")
 	router.HandleFunc("/post/{id}", deletePost).Methods("DELETE")
    
 	log.Println("Server started on port 8000")
 	log.Fatal(http.ListenAndServe(":8000", router))
 }

  3. Save and close the file. Run the server again with the following command:

     go run main.go

  4. Now you can use tools like curl or Postman to send HTTP requests to the server’s endpoints /post and /post/{id}. Implement the corresponding functionality for creating, reading, updating, and deleting blog posts in the respective functions.

Conclusion

Congratulations! You have successfully built a basic blogging platform using Go. In this tutorial, we learned how to create a web server, handle HTTP requests, and implement blogging functionality. You can further enhance the platform by adding authentication, user management, and frontend templates.

Feel free to explore Go’s documentation and other third-party libraries to expand the features of your blogging platform.
