在Go语言世界中，除了标准库自带的html/template包以外，还有种类繁多的第三方模板引擎库，这些库大多来自其余语言的经验继承。css
提起Go语言模板引擎，不少人天然会想到pongo2模板引擎，这也是笔者接触最先的Go语言模板引擎，几乎全部的Go主流流行的Web框架都对它提供支持，你甚至在xormplus/xorm这个数据库框架库中也能看到他的身影，它是一个像django语法的Go语言模板引擎，若是你之前作过python开发，那你必定会对它无比亲切。html
另外一个笔者喜欢的Go语言模板引擎是jet，它功能强大，且高效，性能至关出色。另一大特色是IDE支持，它有一个IDEA插件可供开发者使用，Github地址：https://github.com/jhsx/GoJetPlugin。这也是目前笔者主要使用的Go语言模板引擎之一（之前还有一些老项目是使用pongo2模板引擎的，另外xormplus/xorm中的sql模板也是采用pongo2）。python
还有一个笔者想说起的Go语言模板引擎库是go-template，它更像一个模板引擎适配器，它的最大特点是同时支持standard html/template、amber、django、handlebars、pug(jade)、markdown六种模板引擎。git
Go语言模板引擎其实主要分两大类，一类是非预编译生成Go代码的模板引擎（如以上说起的这些），另外一类则是预编译生成Go代码的模板引擎，这一类模板引擎因为先天优点，性能将更为出色一些，是否采用这类引擎，要看你项目的需求来权衡。这类引擎的佼佼者是hero，也是一位国人开发的Go语言模板引擎库。github
目前笔者使用的Go语言模板引擎主要是pongo2，jet和hero。若是您还有想推荐的Go语言模板引擎库，欢迎留言分享。golang
