golang template usage
Golang is an open source programming language developed by Google. It is designed to be a statically typed, efficient language with strong support for concurrency that can easily handle high-load network services.
With the rapid development of the Internet, web design has become more important. Therefore, developers need a solution that is very user-friendly and convenient when it comes to web design. In this case, Golang's template usage becomes a very valuable tool.
Golang Template
A template is part of a Golang program and is used to display the same or similar data on different pages. This is a common requirement, for example, on an e-commerce website, the same product is usually displayed on different pages. Of course, these pages should have the same design and layout.
Golang’s template system provides a simple and clear way to achieve this requirement. It is based on the standard HTML template language and uses its own set of tags to describe the data to be rendered and related operations.
The combination of Golang and templates provides a great way to dynamically generate web pages, allowing us to use one of the most powerful features in Golang, namely "templated HTML".
How to use Golang templates?
To start using Golang templates, you need to install Golang and then create a template file according to your needs.
The following is a very simple template example:
<!DOCTYPE html>
<html>
<head>
<title>{{.Title}}</title>
</head>
<body>
<h1>{{.Header}}</h1>
<p>{{.Content}}</p>
</body>
</html>In this example, {{.Title}}, {{.Header}}, and {{.Content}} are variables in the Go template. These variables can be set in the parameter list passed to the template processor. When executing the template, the template processor will automatically find and parse this part of the template file.
After becoming familiar with the basic Golang template syntax, we can use it to create complex, dynamic HTML pages or applications. Here are some great examples of use cases:
- Homepage Template
You can use templates to generate the homepage of your website. This template will contain the main elements of the website, such as the website’s logo, menu, page layout, and more. Additionally, it will include a specific code snippet for retrieving news, blog posts, products, and more on the website. The following is an example:
{{define "homepage"}}
<!DOCTYPE html>
<html>
<head>
<title>{{.Title}}</title>
</head>
<body>
<div class="header">
<img src="{{.Logo}}">
<ul>
{{range .Menu}}
<li>{{.}}</li>
{{end}}
</ul>
</div>
<div class="content">
{{template "news" .News}}
{{template "blog" .Blog}}
{{template "products" .Products}}
</div>
</body>
</html>
{{end}}In this template file, we define the homepage template, which contains the head, body and tail of the website. The template uses the . operator to display the required variables and uses template syntax to render the loop.
- Blog List Template
Blogs are a great use case because every blog post can be rendered using the same layout. Here is a sample blog post list:
{{define "blog"}}
<div class="blog-list">
{{range .}}
<div class="blog-post">
<h2>{{.Title}}</h2>
<p>{{.Summary}}</p>
</div>
{{end}}
</div>
{{end}} In this template, we have defined the blog template to loop and display blog posts. The template uses a variable to represent each blog post and displays the title and summary of the post.
- Product Details Template
When shopping online, users usually need to view the detailed information of all products. This is a relatively fixed page that can be reused between different products. The following is an example:
{{define "product-details"}}
<!DOCTYPE html>
<html>
<head>
<title>{{.Name}}</title>
</head>
<body>
<h1>{{.Name}}</h1>
<div class="product-info">
<div class="product-image">
<img src="{{.Image}}">
</div>
<div class="product-description">
<p>{{.Description}}</p>
<p>Price: {{.Price}}</p>
<p>Availability: {{.Available}}</p>
</div>
</div>
</body>
</html>
{{end}} In this template, we define a product-details template to display the details of a single product. The template uses multiple variables to represent different attributes of the product and displays them in a beautiful way.
Summary
Golang’s template system is a very powerful and flexible tool that can help us easily manage and render complex web pages and applications. Its syntax is very simple and easy to understand, which can help us develop applications more efficiently.
If you haven’t used Golang’s template system yet, please give it a try. It might be more powerful and useful than you think!

Golang vs. Python: Performance and Scalability
Apr 19, 2025 am 12:18 AM
Golang is better than Python in terms of performance and scalability. 1) Golang's compilation-type characteristics and efficient concurrency model make it perform well in high concurrency scenarios. 2) Python, as an interpreted language, executes slowly, but can optimize performance through tools such as Cython.
Golang and C : Concurrency vs. Raw Speed
Apr 21, 2025 am 12:16 AM
Golang is better than C in concurrency, while C is better than Golang in raw speed. 1) Golang achieves efficient concurrency through goroutine and channel, which is suitable for handling a large number of concurrent tasks. 2)C Through compiler optimization and standard library, it provides high performance close to hardware, suitable for applications that require extreme optimization.
