How to change handlebars extension for express?

问题

I am new to node.js and I'd like to use handlebars template engine but with a shorten extension hbs.

Here is the original code (source):

var handlebars = require('express3-handlebars')
.create({ defaultLayout: 'main' });
app.engine('handlebars', handlebars.engine);
app.set('view engine', 'handlebars');

It worked fine with templates with handlebars extension, but I changed it to:

var handlebars = require('express3-handlebars')
.create({ defaultLayout: 'main' });
app.engine('hbs', handlebars.engine);
app.set('view engine', 'hbs');

And change all the template extentions to hbs. However, now I get this error:

Error: ENOENT: no such file or directory, open '/path/to/node/myproject/views/layouts/main.handlebars'
   at Error (native)

I also tried

var handlebars = require('express3-handlebars')
.create({ defaultLayout: 'main' , extname : '.hbs'});
app.engine('handlebars', handlebars.engine);
app.set('view engine', 'handlebars');

as per answer here,

but I results in:

Error: Failed to lookup view "500" in views directory "/path/to/myproject/views"

I tried other things too but none worked so wondering how can I fix this?

回答1:

This did the trick:

exphbs = require('express3-handlebars'),
app.engine('hbs', exphbs({defaultLayout: 'main', extname: '.hbs'}));
app.set('view engine', 'hbs');

回答2:

You can use express-hbs instead of express3-handlebars.

Simply, you can do:

var hbs = require('express-hbs');
/*
...
*/
app.engine('hbs', hbs.express4({
  partialsDir   : __dirname +'/views/partials',
  defaultLayout : __dirname +'/views/layouts/default',
  extname       : '.hbs',
  layoutsDir    : __dirname +'/views/layouts',
}));

app.set('view engine', 'hbs');
app.set('views', __dirname + '/views');
