3、配置Nunjucks

1、安装模版

cnpm i egg-view-nunjucks -S

2、配置config/plugin.js

module.exports = {
  // had enabled by egg
  nunjucks : {
    enable: true,
    package: 'egg-view-nunjucks'
  }
};

3、配置config/config.default.js

 // start 配置art
  config.view = {
    defaultViewEngine: 'nunjucks',
    mapping: {
      '.html': 'nunjucks',
    },
  };
  // end atr

4、在app下新建一个view的文件夹

在view文件夹里放置.html文件

5、在controller中使用render

const Controller = require('egg').Controller;
class HomeController extends Controller {
  async index() {
    const { ctx } = this;
    await ctx.render("home")
  }
}
module.exports = HomeController;

6、模版语法

for:
{% for item in Array %}
<p>{{item}}</p>
{% endfor %}
if:
{% if Boolean %}
<p>show</p>
{% endif %}
