Question

我正在尝试学习node.js.我希望能够使用vash视图引擎但由于某种原因我不能让它工作。我看了一篇关于Pluralsight的教程并引用了vash文档，但我一直得到同样的错误。这是我的代码

server.js：

var http = require('http');
var port = process.env.port || 1337;

var express = require("express");
var app = express();

app.set("view engine", "vash");
app.get("/", function (req, res) { 
    res.render("index", { title: "Express + Vash" });
});

var server = http.createServer(app);
server.listen(port);

layout.vash：

<!DOCTYPE html>
<html>
    <head>
        <title>@model.title</title>
    </head>
    <body>
        <div>@html.block("body")</div>
    </body>
</html>

index.vash

@html.extend('views/layout', function(model) { 

    @html.block("body", function(model) {

        <h1>@model.title</h1>
        <p>This id from the server</p>

    })

})

stacktrace：

.vash文件位于项目根目录的views文件夹中。

提前致谢！

Answer 1

每this vash issue以下内容应该有效：

var vash = require('vash');
vash.__express = vash.renderFile;
app.set("view engine", "vash");

Answer 2

在index.vash中，只需使用'/ layout'而不是'views / layout'。

那是：

@html.extend(**'/layout'**, function(model) { ... });

无法使用vash 0.8.0与express 4.12.3一起使用
