In the Go language world, in addition to the HTML/Template package that comes with the standard library, there are a wide variety of third-party template engine libraries, most of which derive from empirical inheritance from other languages.
Mentioning Go language template engine, many people will naturally think of PonGO2 template engine, which is the first Go language template engine that the author contacted. Almost all Go mainstream popular Web frameworks support it, and you can even see it in xormplus/ XORm database framework library. It is a Template engine for the Go language with django-like syntax, which will be familiar if you have ever done Python development.
Another go-language template engine I like is Jet, which is powerful, efficient, and performs quite well. Another big feature is IDE support, which has an IDEA plugin for developers to use at github.com/jhsx/GoJetP… . This is one of the main Go template engines I use (pongo2 was used in some older projects, and SQL templates in XormPlus/XORm also use Pongo2).
Another template engine library I’d like to mention for the Go language is go-Template, which is more like a template engine adapter, It also supports standard HTML/Template, Amber, Django, Handlebars, PUG (Jade), and Markdown.
The language template engine is mainly divided into two major categories, category are precompiled generating code Go template engine (e.g., the above mentioned these), another kind is to precompile generated Go code template engine, this kind of template engine due to congenital advantage, performance will be better some, whether to adopt this kind of engine, to see your project needs to weigh. The leader of this type of engine is Hero, which is also a Go language template engine library developed by a Chinese.
The Go language template engines used by the author are pongo2, Jet and Hero. If you have another Go template engine library you would like to recommend, please share it in the comments.
Below is a list of Go language template engine libraries I have compiled. I believe there is one for you 🙂
