2.在egg中使用handelbars模版引擎

1.安装   egg-view-handlebars
2.在config目录下的plugin,js中配置
  exports.handlebars = {
    enable: true,
    package: 'egg-view-handlebars',
  };
3.在config.default.js下配置
config.view = {
    root: [
      path.join(appInfo.baseDir, 'app/view'),
    ].join(','),
    defaultViewEngine: 'handlebars',
    defaultExtension: '.hbs',
    mapping: {
      '.hbs': 'handlebars',
    }
  };
4.在controller层使用handelbars渲染对应页面
class HomeController extends Controller {
  async index() {
    const { ctx } = this;
    ctx.body = 'hi, egg';
  }
  async news() {
    const { ctx } = this;
    let a={name:"andong"}
    await ctx.render('home.hbs',a);
  }
}
