16 How to Understanding HTML Web Redirect in Golang

Redirects

When we create a website, if the user accesses various pages randomly, the page will not be found. So we need to ‘redirect’ a page if the user performs an action on our website page. For example, after logging in, we will redirect to the dashboard page. Redirect itself is actually standard in HTTP and can be seen on the website page https://developer.mozilla.org/en-US/docs/Web/HTTP/Redirections. We only need to create a 3xx response code and add the destination location header. Luckily in Golang there is a function we can use to make this easier.

15 How to Understanding Web XSS (Cross Site Scripting) in Golang

Introduction to XSS (Cross Site Scripting)

XSS is one of the security issues that usually occurs when creating a website. XSS usually has security holes where people can deliberately enter parameters containing script or Javascript so that the website page can be rendered. The purpose of this XSS is to steal the browser cookies of users who are accessing the website and can cause user accounts to be taken over if we as website owners don’t handle it properly.

14 How to Understanding HTML Template Cache in Golang

Introduction to Cache Templates

In previous program codes that we have studied practically, they were not efficient. Why did it happen? because every time it is accessed it will call a function and describe the data sent into the template so the process requires high levels of execution. Every time the handler is called we will always re-parse the template. So ideally the template only performs parsing once at the beginning when the application is running, then only the template data is cached (stored in memory) so there is no need to access the data and do the parsing again so that the website we create can be faster.

13 How to Understanding HTML Template Function in Golang

Introduction to Function Templates

Apart from accessing fields in templates, we can also access functions or functions in Golang. The way to access a function is the same as accessing a field, but if the function has parameters then we can use additional parameters that are sent when calling the function in the template.

Introduction to Layout Templates

When we create a website page, there are several parts that are always the same on each page, for example header and footer, so if there are parts that are the same it is recommended that they be saved in a separate template so that they can be used in other templates or sometimes we call them reusable. Now, this Golang template supports importing from other templates so we can use it to make website creation easier.

11 How to Understanding HTML Template Action in Golang

Introduction to Action Templates

Not only can we render text in templates, but we can also support action commands such as if branching, for loops and so on. For example, suppose we use if branching like this

10 How to Understanding HTML Template Data in Golang

10 How to Understanding HTML Template Data in Golang

Introduction to Data Templates

If you have studied HTML Templates in the previous article, then we will continue with data templates where we can display this data dynamically by using struct or map data. However, we need to know the changes in the template text. We need to know the name of the field or key that we will use to fill in the dynamic data in the template. We can mention the name of the field or key, for example {{.FieldName}}.
