Support for Hapi.js?

See original GitHub issue

I’m getting an error when trying to use Nunjucks with Hapi.js.

Steps to reproduce:

npm i hapi nunjucks -S

Create a server.js file with the following contents:

'use strict';

var Hapi = require('hapi');
var nunjucks = require('nunjucks');
// var handlebars = require('handlebars');

var serverOptions = {
views: {
  engines: {
      html: nunjucks
  },
  path: 'views'
}
};

var server = new Hapi.Server(3000, serverOptions);
server.route({
method: 'GET',
path: '/',
handler: function (res, reply) {
    reply.view('index', {
        title: 'Nice site',
        name: 'Roger',
        header: 'HEADERR',
        footer: 'FOOTERR'
  });
}
});
server.start(function () {
console.log('Hapi %s server running at %s', Hapi.version, server.info.uri);
});

Create a views/index.html with the following contents:

<!doctype html>
<html lang="en">
<head>
<title>{{ title }}</title>
</head>
<body>

<div class="container">
  {{ header }}

  <header class="page-header">
    <h1>Hello {{ name }}, <small>Welcome back</small></h1>
  </header>

  {{ footer }}
</div>

</body>
</html>

$ npm start
$ open http://localhost:3000

Actual results

$ node server

I ran into this myself. The Nunjucks.compile() method does not export the handlebars-style interface expected by Hapi, but it can be trivially replicated using a combination of Nunjucks’ compile() and render() so I wrote a teeny-tiny module to do it:

https://www.npmjs.org/package/nunjucks-hapi

The following example works:

var Hapi = require('hapi')
var Path = require('path')
var Nunjucks = require('nunjucks-hapi')

var server = new Hapi.Server('localhost', 5000)

// set up templates
server.views({
  engines: {
    html: Nunjucks
  },
  path: Path.join(__dirname, 'views')
})

// Add a route
server.route({
  method: 'GET',
  path: '/test',
  handler: function (request, reply) {
    reply.view('mytemplate',{
      'myvariable': 'myvalue'
    })
  }
})

// start server
server.start()

Hey Paulo - Glad you could get it working, could you tell me what about my module isn’t working for you? I double checked and added inheritance and includes to my example:

https://github.com/seldo/nunjucks-hapi/tree/master/test

And it seems to be working fine. [Edit: I had trouble getting your solution to work initially, deleted that.]

Your solution works too.
