配置渲染模板

npm i egg-view-nunjucks --save

修改默认的的配置文件

config/plugin.js

//初始时的文件
module.exports = {
  // had enabled by egg
  // static: {
  //   enable: true,
  // }
};


//修改后的文件
exports.nunjucks = {
  enable: true,
  package: 'egg-view-nunjucks'
};

config/config.default.js

//初始化时的文件
/* eslint valid-jsdoc: "off" */

'use strict';

/**
 * @param {Egg.EggAppInfo} appInfo app info
 */
module.exports = appInfo => {
  /**
   * built-in config
   * @type {Egg.EggAppConfig}
   **/
  const config = exports = {};

  // use for cookie sign key, should change to your own and keep security
  config.keys = appInfo.name + '_1569550138064_1554';

  // add your middleware config here
  config.middleware = [];

  // add your user config here
  const userConfig = {
    // myAppName: 'egg',
  };

 

  return {
    ...config,
    ...userConfig,
  };
};

//配置模板渲染后的文件
/* eslint valid-jsdoc: "off" */

'use strict';

/**
 * @param {Egg.EggAppInfo} appInfo app info
 */
module.exports = appInfo => {
  /**
   * built-in config
   * @type {Egg.EggAppConfig}
   **/
  const config = exports = {};

  // use for cookie sign key, should change to your own and keep security
  config.keys = appInfo.name + '_1569550138064_1554';

  // add your middleware config here
  config.middleware = [];

  // add your user config here
  const userConfig = {
    // myAppName: 'egg',
  };
  // 选软模板渲染
  config.view = {
    defaultViewEngine: 'nunjucks',
    mapping: {
      '.html': 'nunjucks',
    },
  };
 

  return {
    ...config,
    ...userConfig,
  };
};

router的配置

// app/router.js
'use strict';

/**
 * @param {Egg.Application} app - egg application
 */
module.exports = app => {
  const { router, controller } = app;
  router.get('/', controller.home.index);
  router.get('/list', controller.news.list);
};

页面的请求数据

// app/controller/home.js
'use strict';

const Controller = require('egg').Controller;

class HomeController extends Controller {
  async index() {
    let title = "我是首页"; //向模板传入数据
    await this.ctx.render('index.html',{
      title: title
    });

  } 
}

module.exports = HomeController;

html的页面数据绑定

    
    
    
    


    
    
{{ title }}
