我正在尝试用Bliss替换Jade作为NodeJS上示例Express网站的模板引擎。这是app.js的内容:
var express = require('express'),
routes = require('./routes'),
http = require('http'),
path = require('path'),
Bliss = new require('bliss'),
bliss = new Bliss({ext: '.jhtml'}),
app = express();
app.configure(function(){
app.set('port', process.env.PORT || 3000);
app.set('views', __dirname + '/views');
// app.set('view engine', 'bliss'); /* replaced with app.engine() call below */
app.use(express.favicon(__dirname + '/public/img/favicon.ico'));
app.use(express.logger('dev'));
app.use(express.bodyParser());
app.use(express.methodOverride());
app.use(app.router);
app.use(require('stylus').middleware(__dirname + '/public'));
app.use(express.static(path.join(__dirname, 'public'))); });
app.configure('development', function(){
app.use(express.errorHandler());
app.locals.pretty = true; });
app.get('/', /* routes.index */ function(req, res){
var index = bliss.compile('index');
bliss.render(index); });
http.createServer(app).listen(app.get('port'), function(){
console.log("Express server listening on port " + app.get('port')); });
我已尝试过其他SO问题的一些内容,但我对Node,Express或Bliss不太熟悉,无法调试为什么它会返回以下500错误:
500 TypeError: Object function anonymous() { var __out=[],write=__out.push.bind(__out),__tmp=0,render=this.render;write("index"); return __out.join(''); } has no method 'indexOf'
我非常确信模板和视图设置正确,因为它们非常简单,并且可以密切关注Bliss wiki。
这是由于Bliss与Express不完全兼容吗? 是否有更好的方法将其设置为正常工作?
答案 0 :(得分:0)
这是我如何解决问题
假设我的所有幸福文件都有.js.html扩展名
<强> app.js 强>
var Bliss = require('bliss');
var bliss = new Bliss();
app.set('views', __dirname + '/views/bliss');
app.set('view engine', 'js.html');
app.engine('js.html', function(path, options, fn){
// res.render is calling this
// update context here (available to all templates)
var ctx = options.context;
console.log("context", ctx);
if (typeof ctx === 'undefined') {
ctx = {};
}
// these will write over what's already in the context
ctx.name2 = 'MEH2';
//ctx.name1 = 'MEH1';
//ctx.layout = 'layout2';
var output = bliss.render(path, ctx);
fn(null, output); // fn ==> function(error, str)
});
路由器文件index.js
exports.index = function(req, res){
console.log("ready to render index1.js.html");
var ctx = {context : {name1 : 'mike1'}};
ctx.context.layout = 'layout1';
res.render('index1', ctx);
};
index1.js.html文件
@!(ctx)
@function title() {
WOW @ctx.name1, @ctx.name2
}
@function body() {
<div>
<h2> Hello @ctx.name1</h2>
</div>
}
@*choose the layout based on the context*@
@render(ctx.layout, body, title, ctx)
layout1.js.html
@!(body, title, ctx)
<!DOCTYPE html>
<html>
<head>
<title> @title() </title>
</head>
<body>
<h1> REALLY @ctx.title </h1>
LAYOUT 1
@body()
</body>
</html>
layout2.js.html是相同的,除了LAYOUT 2作为其文本
现在使用app.js / app.engine函数观看如何在不同阶段影响上下文
评论:现在我得到了express.js和bliss的工作,我决定继续使用jade。我喜欢幸福&#39;语法,但除了花太多时间让幸福工作,我决定我还没准备好完全承诺:)
