Go templates
Go has its own template engine that is split into two packages: text/template and html/template. These packages are similar in functionality, with the difference that html/template allows a user to generate HTML code that is safe against code injection, making it suitable for use on web pages and emails. Also, these packages provide coding assistance in other applications such as the configuration for Helm and the Kubernetes package manager.
To specify mapping of a type between a Go template and an application, IntelliJ IDEA uses the gotype comment of the following structure: {{- /*gotype: package/path.type_name*/ -}}.
For Go templates, the commonly used file extensions are:
.gohtml: specifically indicates a Go HTML template, useful if your editor or IDE provides specialized support for these templates. IntelliJ IDEA has association with this extension..tmpl: a general extension for template files, suitable for Go templates..tpl: another general extension for template files used in Go.
