Building a blog with Go and MySQL is a great way to learn web development and database integration. In this guide, you'll explore how to create a simple blog application using the Go programming language and MySQL as the database. We'll cover setting up the development environment, defining database models, handling CRUD operations, and sample code for each step.


Before you get started, make sure you have Go and MySQL installed on your system. Additionally, you should have a basic understanding of web development and SQL.

Setting Up Your Environment

To create a Go and MySQL blog, you'll need to set up your development environment. Here are the essential steps:

  1. Install Go: Download and install Go from the official Go website.
  2. Install MySQL: Install MySQL or use a MySQL container if you prefer Docker.
  3. Install Required Packages: Install necessary Go packages, including the MySQL driver. Use the following command to install the MySQL driver:
                go get -u

Creating Database Tables

You'll need to define the structure of your database by creating tables for your blog. Here's an example of defining a "posts" table in MySQL:

title VARCHAR(255),
content TEXT,

Go Models

In Go, you can create models that represent database tables. Here's a Go struct that corresponds to the "posts" table:

package main
import "time"
type Post struct {
ID int
Title string
Content string
CreatedAt time.Time

Connecting to MySQL

To connect your Go application to MySQL, you'll need to configure a database connection. Here's a sample code snippet for establishing a MySQL connection:

package main
import (
_ ""
func main() {
// Replace with your MySQL credentials and database name
dsn := "user:password@tcp(localhost:3306)/myblog"
db, err := sql.Open("mysql", dsn)
if err != nil {
fmt.Println("Error connecting to MySQL:", err)
defer db.Close()
// Check the connection
err = db.Ping()
if err != nil {
fmt.Println("Error pinging MySQL:", err)
fmt.Println("Connected to MySQL")

Handling CRUD Operations

You can perform CRUD operations (Create, Read, Update, Delete) on your blog posts. Here's an example of inserting a new post into the database:

func createPost(db *sql.DB, post Post) error {
query := "INSERT INTO posts (title, content) VALUES (?, ?)"
_, err := db.Exec(query, post.Title, post.Content)
return err

Similarly, you can create functions to read, update, and delete posts in your blog.

Creating Web Routes

To serve your blog content over the web, you need to create web routes. You can use a web framework like Gorilla Mux or net/http. Here's an example using the net/http package:

package main
import (
func main() {
http.HandleFunc("/", listPosts)
http.HandleFunc("/post/", viewPost)
http.ListenAndServe(":8080", nil)
func listPosts(w http.ResponseWriter, r *http.Request) {
// Retrieve and display a list of posts
func viewPost(w http.ResponseWriter, r *http.Request) {
// Retrieve and display a specific post


Creating a blog with Go and MySQL is an excellent project for learning web development and database integration. This guide covered setting up your development environment, defining database tables, creating Go models, connecting to MySQL, and handling CRUD operations. With this knowledge, you can start building your own blog or expand your web development skills.
