JSHTML不使用Express.js在Node.js中

Question

我似乎不想让JSHTML在Express.js上充当Node.js上的模板引擎。当我安装我的Express.js应用程序并为我创建一个基本应用程序时，我运行它就会得到以下错误消息：

500 TypeError: Property 'engine' of object #<View> is not a function
at View.render (/Users/blackbook/nodejs/ds/node_modules/express/lib/view.js:75:8)
at Function.app.render (/Users/blackbook/nodejs/ds/node_modules/express/lib/application.js:504:10)

at next (/Users/blackbook/nodejs/ds/node_modules/express/node_modules/connect/lib/proto.js:190:15)

我的app.js看起来如下(这是Express.js为我创建的)：

/**
 * Module dependencies.
 */

var express = require('express')
  , routes = require('./routes')
  , http = require('http')
  , path = require('path');

var app = express();

app.configure(function(){
  app.set('port', process.env.PORT || 3000);
  app.set('views', __dirname + '/views');
  app.set('view engine', 'jshtml');
  app.use(express.favicon());
  app.use(express.logger('dev'));
  app.use(express.bodyParser());
  app.use(express.methodOverride());
  app.use(app.router);
  app.use(express.static(path.join(__dirname, 'public')));
});

app.configure('development', function(){
  app.use(express.errorHandler());
});

app.get('/', routes.index);

http.createServer(app).listen(app.get('port'), function(){
  console.log("Express server listening on port " + app.get('port'));
});

我有这样的装置：

• Node.js诉0.8.5
• Express.js@3.0.0rc2
• jshtml@0.2.3

JSHTML目前使用Express.js 2。有计划让引擎与Express.js 3一起工作，但目前我正忙于享受这个夏天！希望在冬天能解决这个问题！

Answer 2

根据https://github.com/visionmedia/express/wiki/Migrating-from-2.x-to-3.x，您可以使用app.engine来实现2-x兼容性。

例如：

var fs = require("fs");
var jshtml = require("jshtml");
app.engine("jshtml", function (path, options, fn) {
    fs.readFile(path, 'utf8', function (err, str) {
        if (err) return fn(err);
        str = jshtml.compile(str,options)(options).toString();
        fn(null, str);
    });
});

Answer 3

consolidate.js被用作许多模板引擎和表达式之间的桥梁。如果您的引擎不受支持，请签出源代码。大多数引擎需要15行代码才能实现。
