I have the following Express 4 view engine setup:
var handlebars = require('express-handlebars').create({
layoutsDir: path.join(__dirname, "views/layouts"),
partialsDir: path.join(__dirname, "views/partials"),
defaultLayout: 'layout',
extname: 'hbs'
});
app.engine('handlebars', handlebars.engine);
app.set('view engine', 'hbs');
app.set('views', path.join(__dirname, "views"));
I have the following file structure:
/views
error.hbs
index.hbs
/partials
menu.hbs
/layouts
layout.hbs
And finally in my route: res.render('index');
And visiting my site, it loads only my index.hbs
template. It does not use my layout.hbs
. I don't get any errors or anything. It just doesn't use the layout even though layout
is set as my default layout in the handlebars config.
Next I tried to change my code to this:
res.render('index', {layout: 'layout'});
Now I get the error:
Error: ENOENT: no such file or directory, open '/.../views/layout.hbs'
So it's like it's not finding my layoutsDir
... What am I missing here?
Next I changed it to this:
res.render('index', {layout: 'layouts/layout'});
Okay so that worked. My layout is now loaded. But then I added in a partial to my layout:
{{> menu }}
Now I get: /.../views/index.hbs: The partial menu could not be found
So what is going on here? How come Handlebars isn't recognizing my layoutsDir
or partialsDir
? It's just not seeing them at all or something. And how come defaultLayout
wasn't being used? I had to specify the layout.
According to the API documentation for express-handlebars if you are changing the file extension from the default .handlebars
then when you set the view engine, all occurrences of handlebars should be replaced with the new extension you wish to use.
So your express setup will need to be updated to:
app.engine('hbs', handlebars.engine);
app.set('view engine', 'hbs');
app.set('views', path.join(__dirname, "views"));
Note: the documentation uses a period before the extension eg .hbs but it seems to work without this.
Full code:
var path = require('path');
var express = require('express');
var app = express();
var http = require('http').Server(app);
var handlebars = require('express-handlebars').create({
layoutsDir: path.join(__dirname, "views/layouts"),
partialsDir: path.join(__dirname, "views/partials"),
defaultLayout: 'layout',
extname: 'hbs'
});
app.engine('hbs', handlebars.engine);
app.set('view engine', 'hbs');
app.set('views', path.join(__dirname, "views"));
app.get('/', function(req, res){
res.render('index');
});
http.listen(3000, function(){
console.log("Server running");
});
In the new handlebars in your use partials you dont have to include its directory in server.js
Take note of these.
const hbs = require('hbs');
const expressHbs = require('express-handlebars');
//view engine setup
app.engine('.hbs', expressHbs({ defaultLayout: 'layout', extname: '.hbs' }));
app.set('view engine', 'hbs');
app.set('views', path.join(__dirname, '../views'));
app.use(express.static(path.join(__dirname, '../public')));
