Express & EJS - layout.ejs not used

问题

Im trying out EJS as a view engine with Express. It seems that my layout.ejs is not used. I have two views index.ejs and layout.ejs both in my 'views' folder. It seems that index.js is rendered but layout.ejs is not. The layout.ejs file should be including a CSS file but when the page is rendered in the browser this is not there. Any test test text that I place in the layout.ejs file is not output with the response.

Am I missing an additional configuration step?

Thanks!

My server.js code:

var express = require('express');

var app = express();
    app.set('view engine', 'ejs');
    app.use(express.static(__dirname + '/public'));
    app.get('/', function(req, res){
            res.render('index.ejs', {title: 'EJS Engine'});
    });

    app.listen(8080);

In my layout.ejs I am linking to a single css file which resides in the public folder.

layout.ejs:

<!DOCTYPE html>
       <html>
       <head>
           <title><%= title %></title>
            <link rel="stylesheet" type="text/css" href="main.css">
       </head>
       <body>
              <%- body %>
       </body>
       </html>

index.ejs

<div id="container">
        index.html
</div>

Here's the module you need: https://www.npmjs.org/package/express-ejs-layouts

Do the following:

npm install express-ejs-layouts // install the layout module from the command line

var express = require("express")
    ,path = require('path')
    ,fs = require('fs')
    ,expressLayouts=require("express-ejs-layouts") // add this requirement
    , app = express();

app.use(express.bodyParser());
app.use(expressLayouts); // add this use()
app.use(express.static(__dirname));

Now the ejs engine should use your layout.

I have a similar issue. In my case I would rather use Jade but I have a requirement for a more "html" style template engine for a particular project. At first I considered express-partials or ejs-locals (as mentioned in a comment by Jonathan Lonowski) or even using html via the pipe or dot syntax within Jade templates (see here for more information about that option and this SO post). I am not able to introduce the additional dependencies for express-partials and ejs-locals into this project. These two projects do look good and might meet your needs.

If you do not want to use these projects, you can do something like the following:

views/layout-head.ejs

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>The title</title>
</head>
<body>

views/layout-foot.ejs

</body>
</html>

views/index.ejs (or any other page)

<% include layout-head %>
This is the index page - <%= title %>
<% include layout-foot %>

routes/index.js

exports.index = function(req, res){
  res.render('index', { title: 'Express' });
}

This is not an optimal solution but it works. Most of my application will be a single page app and I have some other restrictions I have to work within so this works for my needs. This may not the best solution in many cases - especially if you have complex and/or changing layouts.

回答3:

app.set('view options', { layout:'layout.ejs' });

Place layout.ejs into your views folder. Alternately you can place layout.ejs into views/layouts folder and then use

app.set('view options', { layout:'layouts/layout.ejs' });
