Mastering Gin in Golang
<p>Gin is more than just a web framework for Go — it’s a toolkit to build lightning-fast and robust APIs. This ultimate reference guide aims to be your one-stop resource for mastering Gin, featuring in-depth examples and mini-projects.</p>
<h1>Why Choose Gin?</h1>
<h2>Speed Matters</h2>
<p>Gin is lightning-fast, and faster is always better in APIs.</p>
<h2>Simplicity at its Best</h2>
<p>If you’re tired of writing tons of boilerplate code, Gin is your new best friend. It simplifies your code without losing power.</p>
<h2>Middlewares: Your Checkpoints</h2>
<p>Want to add authentication, logging, or CORS policies? Middleware has got you covered.</p>
<h1>Getting Started: Installing Gin</h1>
<p>To install Gin, run the following command:</p>
<pre>
go get -u github.com/gin-gonic/gin</pre>
<h2>Hello, Gin: Basic Routing</h2>
<p>Here’s how to set up a primary Gin server.</p>
<pre>
package main
import "github.com/gin-gonic/gin"
func main() {
r := gin.Default()
r.GET("/hello", func(c *gin.Context) {
c.String(200, "Hello, Gin!")
})
r.Run(":8080")
}</pre>
<h2>Parameters and You</h2>
<p>Capture URL parameters with ease.</p>
<pre>
r.GET("/hello/:name", func(c *gin.Context) {
name := c.Param("name")
c.String(200, "Hello, %s!", name)
})</pre>
<h2>Query Parameters</h2>
<p>Capture query parameters like this:</p>
<pre>
r.GET("/search", func(c *gin.Context) {
query := c.DefaultQuery("q", "none")
c.String(200, "Searched for: %s", query)
})</pre>
<p>Visit <code>http://localhost:8080/search?q=books</code> to test.</p>
<h2>JSON All the Way</h2>
<p>Sending JSON has always been challenging.</p>
