How can I handle errors in the Gin framework?

In Gin, you can handle errors by using middleware to catch and respond to errors globally. Would you like an example?

Yes, please provide an example of error handling middleware.

Sure! You can create a middleware function like this:

func ErrorHandler() gin.HandlerFunc {
    return func(c *gin.Context) {
        defer func() {
            if err := recover(); err != nil {
                c.JSON(http.StatusInternalServerError, gin.H{"error": fmt.Sprintf("%v", err)})
            }
        }()
        c.Next()
    }
}

This will catch any panic and return a 500 error response.

How do I use this middleware in my Gin application?

You can use the middleware by adding it to your Gin router like this:

r := gin.Default()
r.Use(ErrorHandler())
// define your routes here
